Technical Field

The invention relates to the technical field of conveying equipment, in particular to a hopper type conveyor.

Background

When the hopper type conveyor is used for feeding or in the operation process, materials overflow or do not enter the hopper and fall onto the bottom plate of the conveyor, the materials on the bottom plate are more and more after the time, and the conveyor cannot normally operate after accumulation, which is a fatal weakness of the hopper type conveyor. The general solution of the prior art is to open a feed back outlet at the end of the feed inlet of the conveyor, such as the bottom of the left end of fig. 1, and arrange a scraper on the hopper, when the hopper finishes the downward discharge return stroke, the scraper is used to scrape the material on the bottom plate to the feed back outlet, and a special elevator is used to lift the material falling from the feed back outlet to another feed back inlet at the upper part of the end and then enter the hopper.

The hopper conveyor in the prior art has the following defects: 1. to feed back the material on the bottom plate, a feed back outlet, a feed back inlet, lifting equipment and lifting power are additionally added, so that the equipment cost and the use cost are increased. 2. Installation lifting means and newly-increased feed back export and feed back entry have increased area and place space relatively, and have increased environmental pollution such as dust of feed back process. 3. Because the conveyer generally has long conveying distance, and the scraper is always in a scraping state from beginning to end in a return stroke, the scraper has large resistance and is easy to damage, the material scraping effect of certain dead corners on the bottom plate is not ideal, and the phenomenon of accumulation of the bottom plate materials still exists sometimes.

After the structure is adopted, the mechanical property of the scraper blade is better, and the effect of the scraper blade in scraping the materials on the bottom plate into the scraper blade is better.

Furthermore, a shovel plate is arranged at intervals of 3-5 hoppers. After the structure is adopted, the frequency of scraping and conveying away materials on the bottom plate by the shovel plate is reasonable, the requirement of cleaning the materials on the bottom plate can be met, and materials of the shovel plate can be saved relatively.

Furthermore, the vertical plate of the shovel plate is fixed on a hopper shaft in the hopper. After the structure is adopted, because the shaft of the hopper is generally exposed in the hopper, the fixing, such as welding, operation process of the shovel plate is relatively simple; and the shaft of the hopper is generally positioned in the middle of the width direction of the hopper, so that the mechanical property of the shovel plate is better.

Furthermore, the vertical plates of the shovel plates are fixed on two end walls in the hopper. After the structure is adopted, the strength of the shovel plate is relatively large, the supporting and reinforcing effects are also achieved on the hopper, and the shoveling force of the shovel plate is further enhanced.

Furthermore, the two vertical plates of the shovel plate are attached to each other, the first vertical plate is fixed with the hopper, the second vertical plate is connected with a second transverse plate, and the second vertical plate and the second transverse plate are formed by bending a whole steel plate; at least one of the two vertical plates is provided with a plurality of elongated holes extending up and down, the other vertical plate is provided with a plurality of holes, and a plurality of bolts correspondingly penetrate through the elongated holes and the holes on the other vertical plate one by one and are fastened through nuts to adjust the distance between the second transverse plate and the bottom plate. After the structure more than adopting, the height of the second diaphragm of shovel board is the hopper return stroke distance between shovel board and the bottom plate promptly the clearance adjustable, more can satisfy the shovel and scrape and carry away the actual need of material on the bottom plate.

Further, the length dimension of part or all of the second vertical plate is larger than the length dimension of the top of the hopper and smaller than the distance dimension between the two hopper supporting wheels of each hopper; the length dimension of the second transverse plate is larger than that of the top of the hopper and smaller than the distance between the two hopper supporting wheels of each hopper. After the structure is adopted, dead angles on the bottom plate are reduced, and materials between the bottom plate below the two ends of the hopper and the hopper supporting wheel can be basically scraped and transported away.

Furthermore, the top parts of the two ends of the hopper are fixedly provided with a guide plate which guides the materials on a second transverse plate of the shovel plate which is longer than the hopper part back into the hopper. After adopting above structure, further guaranteed to lift on the shovel board and return the in-process of hopper with the material, the material on the shovel board basically can not appear spilling hourglass phenomenon.

As shown in fig. 2, hopper 3 is loaded upward and runs from left to right along the top to the right end after top loading at the left end, then descends to the bottom, hopper 3 is unloaded downward and returns from the bottom, then lifts to the top at the left end, hopper 3 is loaded upward and runs to the right … …, and so on. The top is also called the upper layer, the bottom is also called the lower layer, and the return is also called the return. The above structure is the same as the prior art, and reference is made to the prior patent application with application number 201910445672.6 of the applicant and the name of the invention is a toothed-rope bucket conveyor.

The invention is characterized in that:

the hopper is internally provided with a shovel plate 1 which is used for taking away materials on a bottom plate 8 when the hopper 3 returns and automatically falls into the hopper 3 when the hopper 3 ascends to the top from the bottom along a driving wheel 9 of a driving device in a material conveying state. The vertical plate of blade 1 is fixed in hopper 3 as an integral vertical plate 12 and extends out of the top of hopper 3. It will be understood that the top as referred to herein means when the hopper is facing upwards, i.e. when the hopper is in an upper level. The transverse plate of the shovel 1 fixedly connected to the vertical plate, such as the integral vertical plate 12, faces the end with the feed inlet 2 when the free end of the first transverse plate 11 returns. A gap can be left between the transverse plates of the shovel plate 1, such as the first transverse plate 11, and the bottom plate 8, so as not to be in a shoveling state all the time. It will be understood that the shape of the blade 1 is visually referred to as an L-shaped plate when referring to the return stroke. The included angle between the vertical plate and the transverse plate is generally 90 degrees, and of course, the included angle can be larger than 90 degrees properly, such as within 100 degrees. The vertical plate can also be called a vertical plate or a vertical plate. The transverse plate can also be called a horizontal plate. In the structure described in this paragraph, the vertical plate of the shovel 1 may be a combined vertical plate formed of a first vertical plate 17 and a second vertical plate 18, which are also fixed in the hopper 3 and extend out of the top of the hopper 3. It will be understood that the top here also refers to when the hopper is facing upwards. In the structure described in this paragraph, the horizontal plate may be a second horizontal plate 21, and the free end of the second horizontal plate 21 may also face the end having the feed port 2 in the return stroke, and a gap may be left between the second horizontal plate 21 and the bottom plate 8.

As shown in fig. 7, when the shovel is located at the lower level in the box, i.e. when the hopper faces downward, the end surface of the free end of the first horizontal plate 11 of the shovel 1 may be a slope 16 from inside to outside. Of course, the end surface of the free end of the first horizontal plate 11 of the blade 1 may be a vertical surface as shown in other figures.

When the shovel is located at the lower level in the box, that is, when the hopper 3 faces downward, the end surface of the free end of the second horizontal plate 21 of the shovel may be an inclined surface 16 from inside to outside. Of course, the end surface of the free end of second horizontal plate 21 of blade 1 may be a vertical surface.

Preferably, there is one shovel plate 1 per every 3-5 hoppers, i.e. on the 3 rd hopper and on the 6 th hopper, on the sequentially arranged hoppers, there is one shovel plate … …. Or, on the hoppers arranged in sequence, a shovel plate is arranged on the 4 th hopper, and a shovel plate is arranged on the 8 th hopper, … …. Or, on the hoppers arranged in sequence, a shovel plate is arranged on the 5 th hopper, and a shovel plate is arranged on the 10 th hopper, … …. Of course, other arrangements, such as having a shovel plate on each hopper, are within the scope of the present invention.

The connection structure of shovel plate 1 and hopper 3 can have the following three embodiments:

first, the riser 12 of the blade 1 may be secured, such as welded, to a hopper shaft 14 within the hopper 3.

Or: second, the vertical plates 12 of the shovel 1 may also be fixed, for example welded, to the two end walls 15 inside the hopper 3.

Shovel plate 1 in the above two embodiments is preferably formed by bending a single steel plate.

Or: thirdly, the vertical plates of the shovel plate 1 are two adhered to each other: the first vertical plate 17 is fixed to the hopper 3, for example, by welding, and may be fixed to the hopper shaft 14 or to both end walls 15 in the hopper 3. The second vertical plate 18 is connected with a second transverse plate 21. The second vertical plate 18 and the second horizontal plate 21 are preferably formed by bending a single steel plate. At least one of the two vertical plates, i.e., the first vertical plate 17 and the second vertical plate 18, has a plurality of elongated holes 19 extending up and down as on the first vertical plate 17, and the other vertical plate has a plurality of holes as on the second vertical plate 18, and a plurality of bolts 20 are fastened by nuts to adjust the distance between the second transverse plate 21 and the bottom plate 8 by passing through the elongated holes 19 and the holes on the other vertical plate in a one-to-one correspondence manner as on the circular holes on the second vertical plate. The elongated holes 19 may also be referred to as waist-shaped holes. The plurality of elongated holes 19 in the first riser 17 and the plurality of holes in the second riser 18 are two, three, four, etc. corresponding to each other. One fastening bolt 20 is shown in each elongated hole 19, and there may also be two fastening bolts in each elongated hole 19. The holes in the second riser can also be elongated holes, which are more adjustable. The vertical plate of the shovel plate 1 in the section is a combined vertical plate or a vertical plate of a combined structure.

Part or all of the length dimension of the second riser 18 may be greater than the length dimension of the top of the hopper and less than the dimension of the distance between the two hopper idlers 4 of each hopper 3. The second cross plate 21 may have a length dimension which is greater than the length dimension of the top of the hopper and less than the distance between the two hopper idlers 4 of each hopper 3. It will be understood that the top of the hopper in this section refers to the position of the hopper when facing upwards.

The top of the two ends of the hopper is preferably fixed with a guide plate 22 for guiding the material on the second transverse plate 21 of the shovel plate 1 longer than the hopper 3 back into the hopper. The unfolding is that: the top of the two ends of the hopper is fixed with a material guide plate 22 which is used for receiving the materials on the second transverse plate of the shovel plate longer than the hopper part and guiding the materials back to the hopper when the hopper is positioned at the upper layer. The material guide plate 22 can be fixed at the edge of the top of the hopper, and is positioned right below the second transverse plate 21 when the hopper 3 faces upwards, and extends from inside to outside upwards, the width of the material guide plate can be wider than that of the second transverse plate, and the material guide plate can be in the shape of an outer concave arc surface, so that the material guide effect is better. It will be understood that the top of the hopper in this section refers to the position of the hopper when facing upwards.

It will be understood that the top or bottom of the hopper, and the upper or lower shovel plate, are reversed as the upper level, i.e. the transport, or the lower level, i.e. the return, changes. The top is in the material transporting state, i.e. the upper layer, and the bottom is in the return state, i.e. the lower layer. Conversely, the material is at the bottom when in the material transporting state, i.e. the upper layer, and the top when in the return state, i.e. the lower layer. The upper layer is in the material conveying state, and the lower layer is in the return state. Conversely, the material transporting state, i.e., the upper layer, is the lower state, and the return state, i.e., the lower layer, is the upper state.

It will be understood that fig. 2 is a schematic representation and that the actual product length is much greater than that shown.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
