As shown in FIG. 1 and FIG. 2, the present invention is a self-propelled scraper applied to stainless steel cultivation tanks; the automatic scraper mainly comprises a scraper main body which is placed at the top of a stainless steel culture tank;

as shown in fig. 5 and 6, the scraper main body is a support plate connected to the side baffle of the culture tank through a plurality of limiting wheels, a scraper is rotatably connected to the bottom of the support plate, the scraper is arranged according to the size of the opening of the transverse section of the stainless steel culture tank, the long bottom edge of the scraper is ensured, the wide side edge of the scraper is fully contacted with the inner wall of the culture tank, the scraping effect is ensured, wherein one side of the long top edge of the scraper is rotatably connected with the bottom of the support plate, a fixed support extending back to the culture tank is vertically fixed in the middle of the support plate, a scraper cylinder is rotatably connected to the fixed support, a rotating seat is rotatably connected to the telescopic end of the scraper cylinder, the rotating seat is fixed at the central position of the back of the scraper, and the scraper is driven by the scraper;

as shown in fig. 5 and 6, a group of limiting protruding strips bent towards the outside of the culture tank are arranged at the top of the side baffle of the culture tank, rack-type guide rails are arranged at the top ends of the limiting protruding strips, two connecting rods are rotatably connected to the front end of the support plate through four groups of connecting rod fixing supports which are symmetrical to each other in pairs relative to the axis of the support plate, a power gear is fixed to the end of each connecting rod, the power gear is meshed with the rack-type guide rails, the connecting rods are rotatably connected with the two groups of fixing supports, the tail ends of the two groups of connecting rods are connected to two ends of an output shaft of a speed reducer through a coupler, the speed reducer is a worm-gear speed reducer, the speed reducer is fixed to the support plate through a connecting frame, a motor coaxial with the support; a group of connecting rods are rotatably connected at the axial tail end of the supporting plate through four groups of connecting rod fixing supports which are symmetrical to each other in pairs relative to the axis of the supporting plate, follow-up gears are fixed at the two ends of each connecting rod, and the follow-up gears are meshed with the rack type guide rails;

as shown in fig. 3 to 6, in order to ensure the connection stability of the whole support plate, at least four sets of longitudinal limiting wheels are arranged on the outer side of the support plate, wherein the longitudinal limiting wheels are symmetrical pairwise, the longitudinal limiting wheels are connected to the back of the support plate through a connecting seat connected to the back of the support plate, and the longitudinal limiting wheels are in contact with the surface of the limiting protruding strip facing to one side of the bottom of the culture tank, so that the longitudinal limiting of the scraper main body along the opening direction of the culture tank is realized; at least eight groups of transverse limiting wheels which are symmetrical pairwise are further arranged on the outer side of the supporting plate, the axes of every two groups of transverse limiting wheels are respectively positioned on two sides of the axis of the power gear or the axis of the follow-up gear, the rotating shafts of the transverse limiting wheels are perpendicular to the supporting plate and are installed, and each group of transverse limiting wheels comprises two transverse limiting wheels which are respectively contacted with the inner side and the outer side of the rack type guide rail;

as shown in fig. 3 to 6, since the spool, which is required for the safe and stable prevention of the cylinder and the motor driving, is protected by the tow chain, a tow chain bracket is provided outside the side guard at one side of the cultivation tank, and a cable connector is provided at the side of the scraper main body, and the cable connector is connected to the control terminal at the end of the cultivation tank through the tow chain placed on the tow chain bracket.

As shown in figures 1 and 2, the end baffle plate of the culture tank is designed to be openable and closable, and the bottom of the end baffle plate is rotatably connected with the bottom plate of the culture tank, so that the materials can be discharged conveniently.

The material scraping mode is that the material is scraped from the end of the discharge port in sections according to the preset length, when the first section of material is scraped out of the culture tank, the scraper body moves back from the discharge port to the position of the second section of material, then the second section of material is scraped out of the culture tank, and the operation is repeated until all the materials in the culture tank are emptied; when the scraper body moves back from the discharge hole, the scraper needs to be lifted to the upper part of the culture layer and cannot be contacted with the culture layer, and then descends to the bottom of the culture tank when reaching the second section of material; scraping to the end, opening a baffle plate of the openable culture tank, and discharging the materials; the same side with the openable culture tank baffle can also be used as the feed end of the culture tank, and uniform surface distribution is realized by increasing the backward walking height of the scraper.

When the automatic scraper is used, the collection work of mixed materials such as adult fly maggots, fly maggot manure and residual waste residues after cultivation is finished through automatic walking and scraping, when the scraping stroke is set to be 50cm at each time, the automatic scraper walks for 50cm from the opening end of the baffle of the cultivation tank to the other end, the push plate controlled by the air cylinder is inserted to the bottom of the cultivation layer from the recovery state (tightly attached to the bottom of the tank, and the lower edge of the push plate is provided with a rubber skin to prevent hard contact with the bottom), the automatic scraper pushes the materials which are 50cm long and 15-20cm thick to the opening end of the baffle of the cultivation tank, and the materials slide down from the guide chute to the belt conveyor to be sent to the next process. And after pushing the materials, recovering the push plate, moving the automatic scraper back for a distance of 2 multiplied by 50cm, inserting the push plate down to the bottom of the culture layer again, pushing the materials with the length of 50cm and the thickness of 15-20cm to the opening end of the baffle of the culture tank, after pushing the materials, recovering the push plate, continuing to move for a distance of 3 multiplied by 50cm, and repeating the steps until all the materials in the culture tank are cleaned. The backward travel distance is 1 × 50cm, 2 × 50cm, 3 × 50cm … … N × 50 cm. The reciprocating times are the length of the culture groove divided by 50cm = N times. If the thrust of the motor is increased, the push plate can push 100cm long materials at one time, and the reciprocating times can be reduced by half.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
