Description

Technical Field

[0001] The present invention relates to the technical field of straw returning to the field, and particularly relates to a wheat straw turning and burying device and method. Background Art

[0002] Straw returning to the field is a measure of using straw for returning to the field, which is an important measure for increasing soil fertility and yield that is widely emphasized in the world. It can not only prevent air pollution caused by straw burning but also play a role in increasing fertilizer and yield. Straw returning to the field can increase soil organic matter, improve soil structure, make the soil loose, increase porosity, reduce bulk density, and promote the activity of microorganisms and the development of crop roots. The effect of increasing fertilizer and yield by straw returning to the field is significant, generally increasing production by 5% - 10%. However, if the method is improper, it will also lead to an increase in soil pathogens, an aggravation of crop diseases, and poor phenomena such as seedling shortage (stiff seedlings). Therefore, reasonable straw returning measures are needed to achieve good returning effects.

[0003] A straw returning and crushing mechanism and its straw returning equipment disclosed in Chinese Patent CN117441481B. Under the drive of a drive mechanism, a hay rake mechanism gathers straw in a crushing box, and then the straw is crushed by a crushing mechanism. The crushed straw is scattered by a scattering mechanism. At the same time, when the drive mechanism works, the air inside the air collecting box is blown out through a scattering plate at the lower end of a vertical rotating shaft to blow off the crushed straw that has fallen onto the scattering plate, preventing the crushed straw from accumulating on the scattering plate and affecting the rotation of the scattering plate and the scattering of the subsequent crushed straw falling onto its surface. The air outlet of the air collecting box is connected to an air outlet nozzle through a second air pipe, and the second air pipe is used to blow and clean the front surface of a filter plate through the air outlet nozzle to prevent the filter plate from being blocked.

[0004] When the above-mentioned straw turning and burying device is in use, the mature zone of wheat root tips is densely covered with root hairs, and its surface area is significantly increased. Through physical adsorption, it tightly wraps soil particles to form a stable root - soil complex. When turning the soil and returning the straw to the field, it will directly cover the straw with root hairs on the straw on the other side for landfill, resulting in the soil mass wrapped by root hairs not being crushed. The soil mass wrapped by root hairs remains unchanged due to the physical restraint of the fiber network, forming a significant difference from the crushed soil in the non - wrapped area, affecting the soil permeability and the uniformity of water and fertilizer distribution. Summary of the Invention

A fixed inclined block is arranged on one side of the moving inclined block.

[0016] As a preferred embodiment of the wheat straw turning and burying device of the present invention, a cylinder is fixedly installed on the fixed inclined block. The cylinder is fixedly connected to the forklift body. Two connecting rods are fixedly connected to both sides of the fixed inclined block. One end of each connecting rod is fixedly connected with a driven rack. A driving gear is meshed with one side of the driven rack. The driving gear is fixedly connected to one end of the intercepting plate.

[0017] To achieve the above object, the present invention provides the following technical solution: A method for turning and burying wheat straw, including the following steps:

[0018] Initially, the earth-shoveling side plates and the intercepting plate are both horizontally located on the forklift body. A tractor is connected in front of the forklift body. The equipment is pulled to drive in the field, and the intermittently planted wheat straw is shoveled up. Since the earth-shoveling side plates are horizontally arranged on both sides of the forklift body, the shovels will shovel the straw to be dug into the forklift body;

[0019] The straw and soil shoveled into the forklift body will first slide onto the horizontally placed grid plate. As the rollers in the forklift body rotate, the rotating cams arranged on both sides are driven to rotate. The protruding parts on the rotating cams will gradually push up the ejector pins sliding on the surface, causing one end of the grid plate with the torsion spring to tilt and be in an inclined state. The soil and straw on the grid plate will start to slide towards the crushing roller as the center of gravity shifts. When the protruding part on the rotating cam passes through the ejector pin, the grid plate with the torsion spring will, under the reaction force, quickly drive the ejector pin to slide down from the drop on the rotating cam, causing the grid plate to drive the soil and straw on the grid plate to vibrate, shaking off some of the soil on the grid plate. This operation is repeated, causing the remaining soil and straw to slide into the crushing roller for crushing;

[0020] When the soil with straw is shoveled into the forklift truck body, there is still a certain distance to the next straw without straw. At this time, the intercepting plates symmetrically arranged at one end of the forklift truck body will rotate outward and open to the outside of the forklift truck body. Through the driving sliding column on the upper surface of the intercepting plate sliding in the coordination chute at one end of the lever, the lever is driven to rotate on the forklift truck body, and the driven sliding column at the other end is pushed to slide in the coordination chute, so that the earth-shoveling side plates on both sides rotate and merge into the forklift truck body, and the earth-shoveling side plates at one end of the forklift truck body are merged into a triangle, as Figure 2 shown. At the same time, the just-entered soil and straw will be pushed to slide on the grid plate, and the steps will be reset vice versa;

[0021] At the same time, the originally vertical rotating scraper will rotate with the rotation of the earth-shoveling side plate. The bottom end of the sliding column will contact the shovel blade. As the earth-shoveling side plates on both sides gradually merge, the sliding column will slide onto the surface of the forklift truck body. The sliding column slides upward along the limiting chute at one end of the earth-shoveling side plate, gradually squeezing the reset spring between the sliding column and the earth-shoveling side plate, and driving the coordinated gear engaged on one side to rotate through the driving rack on one side of the sliding column, so that the rotating scraper rotates to a horizontal state along the surface of the earth-shoveling side plate, scraping off the soil attached to the surface of the earth-shoveling side plate, reducing the friction force, and ensuring that the merged earth-shoveling side plates can smoothly push the soil to both sides to dig channels;

[0022] The soil that falls from the grid plate without being crushed falls onto the conveyor belt below. The soil and straw passing through the crushing roller are completely crushed and also fall onto the conveyor belt below for mixing. While the equipment is moving forward, the open intercepting plate will push the earth-shoveling side plates to retrieve the soil on both sides into the forklift truck body. Subsequently, the incoming soil will fall from the mixing tank onto the conveyor belt below, covering the crushed straw, and transporting it to the canal at the rear through the driving conveyor belt for returning to the field;

[0023] Initially, the intercepting plate is in a horizontal state, the air cylinder is in an extended state, the driving gear at one end of the intercepting plate is located at the bottom end of the driven rack, the fixed inclined block is at the top of the moving inclined block, and the moving inclined blocks on both sides are in a merged state;

[0024] The output end of the air cylinder pulls the fixed inclined block to slide along the forklift truck body towards the moving inclined block. At the same time, the driven rack will drive the driving gear engaged on one side to rotate, so that the intercepting plates on both sides open. The fixed inclined block will enter between the moving inclined blocks on both sides along the inclined plane, pushing the moving inclined blocks on both sides to slide towards both sides, so that the sliding blocks on both sides slide along the sliding chute on the upper surface of the limiting frame, driving the sliding plate below to slide along the side surface of the limiting frame. The pulley slides in the inclined chute. While the sliding plate slides towards both sides, the sliding plate will gradually slide downward, so that the connecting rod slides downward in the sleeve, pulling the folding spring at the top of the connecting rod to be taut, and the two pushing plates will push the soil piled in the canal to both sides to spread out.

[0025] The technical solution provided by the present invention has the following beneficial effects compared with the known prior art:

[0026] 1. By the driving sliding column on the upper surface of the intercepting plate sliding in the coordination chute at one end of the lever, driving the lever to rotate on the forklift body, and pushing the driven sliding column at the other end to slide in the coordination chute, the earth-shoveling side plates on both sides rotate and merge towards the inside of the forklift body, so that the earth-shoveling side plates at one end of the forklift body merge into a triangle, which can intermittently shovel the straw in the field according to the wheat planted at intervals, avoiding the situation of equipment blockage or overload caused by dealing with too much material, and preventing the excessive refinement of soil pulverization.

[0027] 2. By the sliding column sliding onto the surface of the forklift body and sliding upward along the limit chute at one end of the earth-shoveling side plate, driving the coordinated gear engaged on one side to rotate through the driving rack on one side of the sliding column, so that the rotating scraper rotates to a horizontal state along the surface of the earth-shoveling side plate, scraping off the soil attached to the surface of the earth-shoveling side plate, reducing the friction force, avoiding the accumulation of soil and affecting the working efficiency of the equipment, and being able to better complete the excavation task.

[0028] 3. While the sliding plate slides to both sides, the sliding plate will gradually slide downward, causing the connecting rod to slide downward in the sleeve, pulling the folding spring at the top of the connecting rod to be taut, and the two pushing plates will push the soil piled up in the canal to both sides to spread out, intermittently leveling the soil pile, which can increase the contact area and friction force between soil particles, thereby improving the stability of the soil and reducing the risk of landslide caused by rain erosion or vibration.

[0044] The intermittent leveling mechanism 300 includes a limit frame 301 and a push flat plate 302 that slides symmetrically on the limit frame 301. The limit frame 301 is fixedly connected to one end of the forklift body 100.

[0045] Embodiment 2

[0046] Refer to Figures 1-6 , which is the second embodiment of the present invention. A wheat straw turning and burying device is provided. The scraping assembly includes a sliding column 203. The sliding column 203 is slidably connected to one end of the soil-shoveling side plate 201. A driving rack 204 is fixedly connected to one side of the sliding column 203. A coordination gear 205 is meshed with one side of the driving rack 204. A rotating scraper 206 is fixedly connected to one side of the coordination gear 205. The rotating scraper 206 is rotatably connected to one side of the soil-shoveling side plate 201. The sliding column 203 is slidably connected to the inner wall of the soil-shoveling side plate 201 in a lifting manner, driving the rotating scraper 206 on one side to rotate along the surface of the soil-shoveling side plate 201 to scrape the soil attached to the surface of the soil-shoveling side plate 201.

[0047] The coordination gear 205 is rotatably connected inside the soil-shoveling side plate 201. A limit sliding groove 207 is opened at one end of the soil-shoveling side plate 201. The sliding column 203 is slidably connected in the limit sliding groove 207. A return spring 208 is fixedly installed in the limit sliding groove 207. One end of the return spring 208 is fixedly installed with the upper surface of the sliding column 203. A limit block 209 is fixedly connected to one side of the sliding column 203. A shovel blade 210 is fixedly connected to one end of the forklift body 100. The limit sliding groove 207 is opened at the other end of the rotating shaft of the soil-shoveling side plate 201. The return spring 208 is arranged between the sliding column 203 and the soil-shoveling side plate 201 to limit the sliding column 203 through the limit block 209.

[0048] The coordination component includes a grid plate 211. One end of the grid plate 211 is connected to the forklift body 100 by a torsion spring. Symmetrically connected to the lower surface of the grid plate 211 are top columns 212. The bottom ends of the top columns 212 slide against a rotating cam 213. The rotating cam 213 is rotatably connected within the forklift body 100. The rotating cam 213 intermittently jacks up one end of the grid plate 211, causing the grid plate 211 of the torsion spring to continuously swing and tilt reciprocally. The highest point of the tilted end does not exceed the surface of the forklift body 100, accelerating the rapid movement of the straw with soil, and the rotating cam 213 is arranged on both sides of the conveyor belt 215, below the side frames on both sides of the grid plate 211.

[0049] Fixedly connected to one side of the rotating cam 213 is a roller 214. A conveyor belt 215 is sleeved on the roller 214. The conveyor belt 215 is arranged within the forklift body 100. One side of the grid plate 211 is provided with a crushing roller 216. An end of the forklift body 100 is provided with a mixing tank 217. One end of the crushing roller 216 is provided with a protective cover, and a driving source capable of simultaneously driving a pair of crushing rollers 216 is arranged within the protective cover. The crushed straw and soil fall onto the conveyor belt 215 below through the crushing roller 216.

[0050] Rotatably connected to the forklift body 100 is a lever 218. Coordination chutes 219 are opened at both ends of the lever 218. Fixedly connected to the upper surface of the earth-moving side plate 201 is a driven sliding column 220. Fixedly connected to the upper surface of the intercepting plate 202 is a driving sliding column 221. The driven sliding column 220 and the driving sliding column 221 are respectively slidably connected within the coordination chutes 219. One end of the lever 218 is slidably connected to the driven sliding column 220, and the other end of the lever 218 is slidably connected to the driving sliding column 221.

[0051] Specifically, initially, the earth-moving side plate 201 and the intercepting plate 202 are both horizontally located on the forklift body 100. A tractor is connected in front of the forklift body 100, pulling the equipment to travel in the field and intermittently shoveling up the wheat straw planted at intervals. Since the earth-moving side plate 201 is horizontally arranged on both sides of the forklift body 100, the shovel 210 will shovel the straw to be excavated into the forklift body 100.

[0052] The straw and soil shoveled into the forklift body 100 will first slide onto the horizontally placed grid plate 211. As the roller 214 in the forklift body 100 rotates, it drives the rotating cams 213 arranged on both sides to rotate. The protruding parts on the rotating cams 213 will gradually lift the ejector pins 212 sliding on the surface, causing one end of the grid plate 211 with the torsion spring to tilt and be in an inclined state. The soil and straw on the grid plate 211 will start to slide towards the crushing roller 216 as the center of gravity shifts. When the protruding part on the rotating cam 213 passes through the ejector pin 212, the grid plate 211 with the torsion spring will, under the reaction force, quickly drive the ejector pin 212 to slide down from the drop on the rotating cam 213, causing the grid plate 211 to drive the soil and straw on the grid plate 211 to vibrate, shaking off some of the soil on the grid plate 211. This process repeats, causing the remaining soil and straw to slide into the crushing roller 216 for crushing;

[0053] When the soil with straw is shoveled into the forklift body 100, there is still some distance to the next straw without straw. At this time, the intercepting plates 202 symmetrically arranged at one end of the forklift body 100 will rotate outwards and open towards the outside of the forklift body 100. Through the driving sliding columns 221 on the upper surface of the intercepting plates 202 sliding in the coordination chutes 219 at one end of the lever 218, it drives the lever 218 to rotate on the forklift body 100, pushing the driven sliding columns 220 at the other end to slide in the coordination chutes 219, causing the earth-moving side plates 201 on both sides to rotate inwards and merge into the forklift body 100, making the earth-moving side plates 201 at one end of the forklift body 100 merge into a triangle, as Figure 2 shown. At the same time, it will push the just-entered soil and straw to slide onto the grid plate 211. The steps will be reset vice versa;

[0054] At the same time, the originally vertical rotating scraper 206 will rotate as the earth-moving side plates 201 rotate. The bottom end of the sliding column 203 will contact the shovel blade 210. As the earth-moving side plates 201 on both sides gradually merge, the sliding column 203 will slide onto the surface of the forklift body 100. The sliding column 203 slides upwards along the limit chute 207 at one end of the earth-moving side plate 201, gradually compressing the return spring 208 between the sliding column 203 and the earth-moving side plate 201, and driving the coordinated gear 205 engaged on one side to rotate through the driving rack 204 on one side of the sliding column 203, causing the rotating scraper 206 to rotate to a horizontal state along the surface of the earth-moving side plate 201, scraping off the soil attached to the surface of the earth-moving side plate 201, reducing the friction, and ensuring that the merged earth-moving side plates 201 can smoothly push the soil to both sides to form a channel;

[0055] The soil that falls from the grid plate 211 without being crushed lands on the conveyor belt 215 below. The soil and straw that pass through the crushing roller 216 are completely crushed and also land on the conveyor belt 215 below for mixing. While the equipment is moving forward, the open intercepting plate 202 will push the soil shoveling side plates 201 to both sides to scoop back the soil into the forklift body 100. Subsequently, the incoming soil will fall from the mixing tank 217 onto the conveyor belt 215 below to cover the crushed straw, and it will be conveyed to the canal at the rear through the driving conveyor belt 215 for returning to the field.

[0056] Embodiment 3

[0057] Refer to Figures 7-8 , which is the third embodiment of the present invention. A wheat straw turning and burying device is provided. The leveling assembly includes a sliding groove 303. The sliding groove 303 is opened on the upper surface of the limiting frame 301. A sliding block 304 is slidably connected in the sliding groove 303. One side of the sliding block 304 is fixedly connected with a sleeve 305. A folding spring 306 is fixedly installed in the sleeve 305. A connecting rod 307 is slidably connected in the sleeve 305. The bottom end of the connecting rod 307 is fixedly connected with a sliding plate 308. The sleeve 305 and the sleeved connecting rod 307 have the same shape, both being polygonal, which can prevent the connecting rod 307 from rotating in the sleeve 305. The folding spring 306 is arranged between the sleeve 305 and the connecting rod 307.

[0058] The sliding plate 308 is slidably connected with one side of the limiting frame 301. One side of the sliding plate 308 is symmetrically rotatably connected with pulleys 309. The other side of the sliding plate 308 is fixedly connected with the pushing flat plate 302. Tilted grooves 310 are symmetrically opened on the limiting frame 301. The top end of the sleeve 305 is fixedly connected with a moving inclined block 311. One side of the moving inclined block 311 is provided with a fixed inclined block 312. The shape of the fixed inclined block 312 is triangular, which can move through between the two moving inclined blocks 311 along the inclined plane to push the sliding plate 308 connected below to slide. The inclined grooves 310 are inclinedly opened on the limiting frame 301.

[0059] A cylinder 313 is fixedly installed on the fixed inclined block 312. The cylinder 313 is fixedly connected to the forklift body 100. Both sides of the fixed inclined block 312 are fixedly connected with connecting rods 314. One end of the connecting rod 314 is fixedly connected with a driven rack 315. One side of the driven rack 315 is engaged with a driving gear 316. The driving gear 316 is fixedly connected to one end of the intercepting plate 202. The cylinder 313 can intermittently push the fixed inclined block 312 to slide on the forklift body 100.

[0060] Specifically, initially, the interception plate 202 is in a horizontal state, the cylinder 313 is in an extended state, the driving gear 316 at one end of the interception plate 202 is located at the bottom end of the driven rack 315, the fixed inclined block 312 is at the top end of the moving inclined block 311, and the moving inclined blocks 311 on both sides are in a combined state;

[0061] The output end of the cylinder 313 pulls the fixed inclined block 312 to slide along the forklift body 100 towards the moving inclined block 311. At the same time, the driven rack 315 drives the meshing driving gear 316 on one side to rotate, causing the interception plates 202 on both sides to open. The fixed inclined block 312 enters between the moving inclined blocks 311 on both sides along the inclined surface, pushing the moving inclined blocks 311 on both sides to slide towards both sides, causing the sliding blocks 304 on both sides to slide along the sliding grooves 303 on the upper surface of the limiting frame 301, driving the lower sliding plate 308 to slide along the side surface of the limiting frame 301. The pulley 309 slides in the inclined groove 310. While the sliding plate 308 slides towards both sides, the sliding plate 308 gradually slides downward, enabling the pushing plate 302 to be in contact with the soil for a longer time, pushing more soil, pushing the raised part in the middle of the soil pile towards both sides, causing the connecting rod 307 to slide downward in the sleeve 305, pulling the folding spring 306 at the top end of the connecting rod 307 to be taut, and the two pushing plates 302 pushing the soil piled in the canal to spread out towards both sides.

[0062] Embodiment 4

[0063] Refer to Figures 1-8 , which is the fourth embodiment of the present invention, provides a method for turning and burying wheat straw into the field, including the following steps:

[0064] Initially, the soil shoveling side plates 201 and the interception plates 202 are both horizontally located on the forklift body 100. A tractor is connected in front of the forklift body 100 to pull the equipment to travel in the field, intermittently shoveling up the wheat straw planted at intervals. Since the soil shoveling side plates 201 are horizontally arranged on both sides of the forklift body 100, the shovel blades 210 will shovel the straw to be excavated into the forklift body 100;

[0065] The straw and soil shoveled into the forklift body 100 will first slide onto the horizontal grid plate 211. As the roller 214 in the forklift body 100 rotates, it drives the rotating cams 213 arranged on both sides to rotate. The protruding parts on the rotating cams 213 will gradually lift the ejector pins 212 sliding on the surface, causing one end of the grid plate 211 with the torsion spring to tilt and be in an inclined state. The soil and straw on the grid plate 211 will start to slide towards the crushing roller 216 as the center of gravity shifts. When the protruding part on the rotating cam 213 passes through the ejector pin 212, the grid plate 211 with the torsion spring will, under the reaction force, quickly drive the ejector pin 212 to slide down from the drop on the rotating cam 213, causing the grid plate 211 to drive the soil and straw on the grid plate 211 to vibrate, shaking off some of the soil on the grid plate 211. This process repeats, causing the remaining soil and straw to slide into the crushing roller 216 for crushing;

[0066] When the soil with straw is shoveled into the forklift body 100, there is still some distance to the next straw without straw. At this time, the intercepting plates 202 symmetrically arranged at one end of the forklift body 100 will rotate outwards and open towards the outside of the forklift body 100. Through the driving slide columns 221 on the upper surface of the intercepting plates 202 sliding in the coordination chutes 219 at one end of the lever 218, it drives the lever 218 to rotate on the forklift body 100, pushing the driven slide columns 220 at the other end to slide in the coordination chutes 219, causing the shoveling side plates 201 on both sides to rotate inwards and merge into the forklift body 100, making the shoveling side plates 201 at one end of the forklift body 100 merge into a triangle, as Figure 2 shown. At the same time, it will push the just-entered soil and straw to slide onto the grid plate 211. The steps will be reset vice versa;

[0067] At the same time, the originally vertical rotating scraper 206 will rotate as the shoveling side plates 201 rotate. The bottom end of the sliding column 203 will contact the shovel 210. As the shoveling side plates 201 on both sides gradually merge, the sliding column 203 will slide onto the surface of the forklift body 100. The sliding column 203 slides upwards along the limit chute 207 at one end of the shoveling side plate 201, gradually compressing the return spring 208 between the sliding column 203 and the shoveling side plate 201, and driving the coordinated gear 205 engaged on one side to rotate through the driving rack 204 on one side of the sliding column 203, causing the rotating scraper 206 to rotate to a horizontal state along the surface of the shoveling side plate 201, scraping off the soil attached to the surface of the shoveling side plate 201, reducing the friction, and ensuring that the merged shoveling side plates 201 can smoothly push the soil to both sides to form a channel;

[0068] The soil that falls from the grid plate 211 without being crushed lands on the lower conveyor belt 215. The soil and straw that pass through the crushing roller 216 are completely crushed and also land on the lower conveyor belt 215 for mixing. While the equipment is moving forward, the open intercepting plate 202 will push the earth-moving side plates 201 to both sides to retrieve the soil that has been scooped up and bring it into the forklift body 100. Subsequently, the incoming soil will fall from the mixing tank 217 onto the lower conveyor belt 215 to cover the crushed straw, and it will be conveyed by the driving conveyor belt 215 to the canal at the rear for returning to the field.

[0069] Initially, the intercepting plate 202 is in a horizontal state, the cylinder 313 is in an extended state, the driving gear 316 at one end of the intercepting plate 202 is located at the bottom of the driven rack 315, the fixed inclined block 312 is at the top of the moving inclined block 311, and the moving inclined blocks 311 on both sides are in a combined state.

[0070] The output end of the cylinder 313 pulls the fixed inclined block 312 to slide along the forklift body 100 towards the moving inclined block 311. At the same time, the driven rack 315 will drive the meshing driving gear 316 on one side to rotate, causing the intercepting plates 202 on both sides to open. The fixed inclined block 312 will enter between the moving inclined blocks 311 on both sides along the inclined plane, pushing the moving inclined blocks 311 on both sides to slide towards both sides, causing the sliding blocks 304 on both sides to slide along the sliding grooves 303 on the upper surface of the limit frame 301, driving the lower sliding plate 308 to slide along the side of the limit frame 301. The pulley 309 slides in the inclined groove 310. While the sliding plate 308 slides towards both sides, the sliding plate 308 will gradually slide downwards, enabling the pushing plate 302 to be in contact with the soil for a longer time, pushing more soil, pushing the raised part in the middle of the soil pile towards both sides, causing the connecting rod 307 to slide downwards in the sleeve 305, pulling the folding spring 306 at the top of the connecting rod 307 to be taut, and the two pushing plates 302 will push the soil piled in the canal to spread out towards both sides.

A tractor is connected in front of the forklift body (100). The pulling device travels in the field, intermittently shoveling up the wheat straws planted at intervals. Since the earth-moving side plates (201) are horizontally arranged on both sides of the forklift body (100), the shovels (210) will shovel the straws to be excavated into the forklift body (100). The straw and soil shoveled into the forklift body (100) will first slide onto the horizontally placed grid plate (211). As the roller (214) in the forklift body (100) rotates, it drives the rotating cams (213) arranged on both sides to rotate. The raised parts on the rotating cams (213) will gradually lift the ejector pins (212) sliding on the surface, causing one end of the grid plate (211) of the torsion spring to tilt and be in an inclined state. The soil and straw on the grid plate (211) will start to slide towards the crushing roller (216) as the center of gravity shifts. When the raised part on the rotating cam (213) passes through the ejector pin (212), the grid plate (211) of the torsion spring will, under the reaction force, quickly drive the ejector pin (212) to slide down from the drop on the rotating cam (213), causing the grid plate (211) to drive the soil and straw on the grid plate (211) to vibrate; When the soil with straw is shoveled into the forklift body (100), there is still some distance to the next straw without straw at this time. At this time, the intercepting plates (202) symmetrically arranged at one end of the forklift body (100) will rotate outwards and open towards the outside of the forklift body (100).

The bottom end of the sliding column (203) will abut against the shovel blade (210). As the earth-moving side plates (201) on both sides gradually merge, the sliding column (203) will slide onto the surface of the forklift body (100). The sliding column (203) slides upwards along the limit chute (207) at one end of the earth-moving side plate (201), gradually squeezing the return spring (208) between the sliding column (203) and the earth-moving side plate (201), and driving the coordinated gear (205) engaged on one side to rotate through the driving rack (204) on one side of the sliding column (203), causing the rotating scraper (206) to rotate to a horizontal state along the surface of the earth-moving side plate (201) and scraping off the soil attached to the surface of the earth-moving side plate (201); The soil that falls from the grid plate (211) without being crushed lands on the conveyor belt (215) below.
