Background

During salt making, brine needs to be put into a salt pond for airing, redundant water is evaporated, and salt particles can be crystallized after the brine reaches the crystallization concentration. In the process of airing, if the user encounters rainy days, rainwater enters the salt pond to dilute brine, so that the crystallization is slow. Therefore, in rainy days, a plastic mat needs to be covered on the salt pond. In the prior art, two methods are generally adopted for preventing covering, and one method is manual covering. Because the salt pond area is big, can think that the manual work covers consuming time and wasting force, especially when the high wind storms, can't satisfy and cover the requirement. The second is automatic covering, such as the slideway system of plastic tarpaulin track-entering device in salt pan with application number 201810597375.9. Then in the practical application process, the hanging head or the hanging ball can keep the overturning state, and the rest surfaces of the plastic tarpaulin are attached but not positioned on the outer side of the plastic tarpaulin in the state, so that the machine is blocked by a rail entering machine, the covering efficiency is influenced, and the machine is damaged. Although the technology improves a certain degree of automation, in order to solve the above problems, a manual mode is often adopted to turn over the hanging head attached to the plastic mat, and then the purpose of smoothly entering the plastic mat is achieved. Then, the labor cost of manual work is high, and in rainy days, particularly in thunderstorm days, manual outdoor operation is extremely dangerous, so that the rail entering device capable of correcting the hanging head is designed to meet the urgent requirement. Furthermore, due to the particularity of the salt pan environment and the operation environment of the rail entering device, namely the rainy day environment and the salt pond watery environment, the design of the special driving device for the turnover hanging head is an urgent requirement.

Detailed Description

In order to make the technical solution and the advantages of the present invention clearer, the following explains embodiments of the present invention in further detail.

As shown in fig. 14, a rail inserter for correcting a reverse rotation of a hanging head includes a rail inserter assembly 100. In the prior art, the rail insertion device assembly 100 is provided with a front end plate, which is provided with an upper front end plate and a lower front end plate, which are respectively a rail insertion lower slideway front end plate 121 and a rail insertion upper slideway front end plate 122. The front end plate 121 of the lower rail-entering slideway and the front end plate 122 of the upper rail-entering slideway form a symmetrical or asymmetrical horn shape, and the two are respectively led into the plastic film cover rail-entering slideway 130 through the rear end plate of the lower rail-entering slideway and the rear end plate of the upper rail-entering slideway. On the basis of the prior art, the present invention further comprises a flipping brush 200 and a driving device 300 for driving the flipping brush 200 to rotate. The overturning hairbrush 200 is arranged between the front end plate 121 of the lower slideway of the rail entering and the front end plate 122 of the upper slideway of the rail entering, and the overturning hairbrush 200 in a rotating state enables a plastic tarpaulin hanging head which is inverted to the inner side of the plastic tarpaulin to turn to the outer side of the plastic tarpaulin from the inner side of the plastic tarpaulin, so that the plastic tarpaulin hanging head can smoothly enter the plastic tarpaulin rail entering slideway 130.

The flipping brush 200 includes a brush spindle 210, a spindle holder 220, and a brush body 230. The shaft holder 220 is used to fix the brush shaft 210, and the technique commonly used in the prior art is adopted, that is, the shaft holder 220 is rotatably connected with the end of the brush shaft 210 through a bearing, and the shaft holder 220 can be fixedly connected with the front end plate and also can be fixedly connected with the side wall of the salt pond. Meanwhile, the connection relationship of the rotating shaft fixing bracket 220 can be determined according to the number or the group number of the turnover brushes 200. When one or a group of overturn brushes 200 are arranged, the rotating shaft fixing frame 220 can be connected with the front end plate 121 of the lower slideway of the in-orbit and can also be connected with the front end plate 122 of the upper slideway of the in-orbit. When two or two groups are provided, the upper rotating shaft fixing frame 220 is connected with the front end plate 122 of the upper track slideway, and the lower rotating shaft fixing frame 220 is connected with the front end plate 121 of the lower track slideway or the side wall of the salt pond. The brush rotating shaft 210 is used for installing the brush body 230, and the end of the brush rotating shaft 210 is connected with the rotation output part of the driving device, so as to drive the brush rotating shaft 210 to rotate, and further drive the brush body 230 to rotate. One surface of the brush body 230 is provided with bristles, and the other surface is fixedly connected with the brush rotating shaft 210.

Alternatively, the brush rotating shaft 210 and the brush body 230 are integrally formed, that is, the bristles are directly disposed on the rotating shaft.

The brush body 230 may be provided as a swept body having a cone shape, a cylinder shape, a transfer belt shape, or a curved line, or bristles provided at the brush body 230 are trimmed to have a cone shape or a cylinder shape. The method specifically comprises the following steps:

a conical state

The brush body 230 is tapered, and the tip of the brush body 230 is smoothly processed to prevent damage to the plastic film. The bristles provided on the brush body 230 have the same length, and the overall shape of the reversible brush 200 is tapered. Or the whole shape of the brush hair is conical, and the tip of the cone is a smooth curved surface. At this time, the shape of the brush body 230 may be indefinite, and the bristles are shaped into a cone shape by trimming.

The axial line direction, i.e. the length direction, of the turnover brush 200 may be parallel to the horizontal plane, or may be parallel to the advancing direction of the plastic film cover, or may be tangent to the inner side surface of the front end plate. When tangent with the inboard surface of front end plate, from the statistics of the direction of the upset of the plastic tarpaulin hanger that the scene feedbacks, it is tangent with the medial surface of entrygut glide slope front end plate 121 when setting up an upset brush 200 alone, two or upper and lower two sets of time, lower part and entrygut glide slope front end plate 121 are tangent, upper portion can be tangent with entrygut glide slope front end plate 121, also can be tangent with entrygut glide slope front end plate 122.

Further, since the plastic tarpaulin is mostly in a horizontal state or a state close to the horizontal state in the advancing process, the conical surface of the turnover brush 200 is parallel to the horizontal plane. At this moment, the side face of the rotating overturning brush 200 is always parallel to the plastic tarpaulin, so that a larger contact area is provided, and the overturning of the plastic tarpaulin hanging head can be realized.

Further, the end of the flipping brush 200 points in the direction of the side wall of the salt pond. At this time, even if the driving device 300 fails and cannot rotate, the overturned plastic tarpaulin hanging head can be corrected to be in a correct position. Or, the function of correcting the plastic film cover hanging head can be realized only by installing the overturning brush 200.

(II) cylindrical state

The brush body 230 is a cylinder, which may be a cylinder. Or the overall shape thereof is a cylinder by trimming the bristles of the reversible brush 200.

The axial line direction, i.e. the length direction, of the turnover brush 200 may be parallel to the horizontal plane, or may be parallel to the advancing direction of the plastic film cover, or may be tangent to the inner side surface of the front end plate. When tangent with the inboard surface of front end plate, from the statistics of the direction of the upset of the plastic tarpaulin hanger that the scene feedbacks, it is tangent with the medial surface of entrygut glide slope front end plate 121 when setting up an upset brush 200 alone, two or upper and lower two sets of time, lower part and entrygut glide slope front end plate 121 are tangent, upper portion can be tangent with entrygut glide slope front end plate 121, also can be tangent with entrygut glide slope front end plate 122.

Further, the end of the flipping brush 200 points in the direction of the side wall of the salt pond. At this time, even if the driving device 300 fails and cannot rotate, the overturned plastic tarpaulin hanging head can be corrected to be in a correct position. Or, the function of correcting the plastic film cover hanging head can be realized only by installing the overturning brush 200.

(III) curved swept volume State

The brush rotating shaft 210 is a flexible shaft, and the length direction of the flexible shaft is parallel to the inner side surface of the front end plate. Specifically, the axis of the flexible shaft is a curve parallel to or coincident with the inner side surface of the front end plate 121 of the lower slideway of the rail. In order to fix the flexible shaft, two ends of the brush rotating shaft (210) are respectively provided with a rotating shaft fixing frame (220). The brush body (230) is made of flexible materials, one surface of the brush body is attached to the flexible shaft, and bristles are arranged on the other surface of the brush body (230). Or the brush body 230 is a rubber ring sleeved on the flexible shaft. The brush body is provided with a plurality of and even distribution on the flexible axle. Bristles are arranged on the outer side surface of the brush body 230.

When two upper and lower reverse brushes are provided, the brush bodies 230 at the upper and lower sides are alternately disposed to reduce resistance between the brushes.

Further, the end of the flipping brush 200 points in the direction of the side wall of the salt pond. At this time, even if the driving device 300 fails and cannot rotate, the overturned plastic tarpaulin hanging head can be corrected to be in a correct position. Or, the function of correcting the plastic film cover hanging head can be realized only by installing the overturning brush 200.

Because the pulling force of the plastic tarpaulin is not constant in the advancing process, and the edge of the plastic tarpaulin is not neat from the reel in the rolling process, the position of the edge of the plastic tarpaulin in the advancing process on the inner side surface of the front end plate is changed at any time. In order to realize the omnibearing correction of the plastic tarpaulin hanging head, a turnover brush 200 with wide coverage is needed. The method specifically comprises the following two steps:

planar array mode

The correction range is covered by the way that the three turning brushes (one), (two) and (three) 200 are arranged side by side on the horizontal plane. The three inversion brushes 200 may be arranged side by side on a surface parallel to the surface of the undertrack nose plate 121. The direction of the side-by-side arrangement can be perpendicular to or cross with the travelling direction of the plastic tarpaulin.

(V) mode of wide brush body

As shown in fig. 12, two brush rotating shafts 210 are provided, and the two brush rotating shafts 210 are arranged side by side on the inner side surface of the front end plate, and the parallel direction is perpendicular to the advancing direction of the plastic tarpaulin. One of the brush rotating shafts 210 is located at one end close to the side wall of the salt pond, and the other brush rotating shaft 210 is located at one end far away from the side wall of the salt pond.
