Description

Technical Field

[0001] This invention relates to the field of agricultural machinery and equipment technology, and specifically to an auxiliary device for crop rotation between crop strips. Background Technology

[0002] Wide-row corn intercropping with wheat and green manure belt rotation is a diversified planting technique integrating intercropping, rotation, and multiple cropping. It can effectively improve the efficiency of light energy, water and fertilizer use, and increase the yield of the system. By crushing and compacting the straw into the field with machinery and introducing green manure, soil fertility is improved, which can partially replace chemical nitrogen fertilizer, achieving a win-win situation for both yield and ecological benefits. Directly returning straw to the field can increase soil organic matter, improve soil physical and biological properties, return soil nutrients, and save fertilizer. It also has the characteristics of being quick, time-saving, and labor-saving, saving farming time. In addition, mulching can also suppress weed growth.

[0003] Existing crushing and returning machinery typically uses rotary cutters to directly cut and crush crops before returning them to the field, which has the following drawbacks:

[0004] (1) Poor straw crushing effect, uneven straw crushing and mixing of crop straw and stubble prevent the soil from making close contact with the seeds, affecting seed germination and reducing the emergence rate. In particular, some crushed materials that are relatively large in volume and hard in texture are not easy to decompose and transform into organic fertilizer, making the soil too loose, with uneven pore size ratio and too many large pores, resulting in moisture loss;

[0005] (2) When crops are being crushed, although the straw and soil are often exposed to the sun in advance to improve crushing efficiency, sometimes the inside of the straw is damp because it is difficult to observe, which increases the difficulty of uniform crushing. Therefore, the present invention aims to provide a device that can improve the efficiency of crop plowing and returning to the field. Summary of the Invention

[0006] To address these shortcomings, the present invention provides a crop rotation auxiliary device to overcome the aforementioned deficiencies in the prior art.

[0007] A crop rotation auxiliary device includes:

[0008] The frame, which is attached to the agricultural machinery;

[0009] The turning and compacting mechanism is used to crush crop straw and crop stubble and return them to the field;

[0010] The feed screen is used to separate the soil and crop debris crushed and thrown up by the turning and compacting mechanism.

[0011] The feeding mechanism includes a feeding cylinder that receives crop debris at the top. Several fine material inlets are equidistantly arranged at the bottom of the feeding cylinder, and several coarse material inlets are arranged on both sides of the feeding cylinder, interspersed with the fine material inlets. Two oscillating filter plates are symmetrically hinged to the cylinder shaft of the feeding cylinder, forming a fine material cavity between the two oscillating filter plates and a coarse material cavity above the oscillating filter plates. An arc plate, which fits against the inner wall of the feeding cylinder, is provided on the side of the oscillating filter plate facing the fine material cavity. The arc length of the arc plate is greater than the corresponding diameter of the coarse material inlet. The oscillating filter plate is driven by a power mechanism to swing up and down on a horizontal plane. When the oscillating filter plate swings to the lower position, the arc plate no longer covers the coarse material inlet.

[0012] A soil compaction roller is used to compact soil that has been turned over and returned to the field.

[0013] A drying mechanism is installed inside the receiving cylinder to dry crop debris before it is discharged.

[0014] Preferably, the guide screen plate is an arc-shaped screen plate, the bottom surface of the arc-shaped screen plate is tangent to the horizontal plane, and the arc-shaped lower end of the arc-shaped screen plate extends to the opening above the material receiving cylinder.

[0015] Preferably, the frame includes two symmetrically arranged main boards, the flipping mechanism, the guide screen plate and the feeding mechanism are all installed between the main boards, and a housing is provided above the main boards, with a baffle plate provided on the side of the housing facing the agricultural machinery.

[0016] Preferably, the flipping mechanism includes a blade roller rotatably mounted between the main plates. The blade roller has several rows of spirally arranged, overlapping and staggered Y-shaped moving blades in the circumferential direction. The Y-shaped moving blades are connected to the blade roller by moving blade pins. A fixed blade plate is installed on the inner wall of the crushing chamber of the frame. The Y-shaped moving blades can pass through the fixed blade plate during rotation. The blade roller is connected to a rotating shaft parallel to the blade roller through a pulley. The other end of the rotating shaft extends to the middle of the frame and is driven to rotate by a gear transmission mechanism.

[0017] Preferably, the power mechanism includes a guide sleeve plate vertically mounted on the frame, the guide sleeve plate passing through the middle of the material receiving cylinder, an arc-shaped guide plate at the top of the guide sleeve plate, the inner end of the oscillating filter plate hinged to both sides of the guide sleeve plate, a sliding pressure block slidably mounted on the guide sleeve plate, the two sides of the sliding pressure block being slidably connected to the side ends of the oscillating filter plate via a folded connecting rod, a connecting rod hinged to the sliding pressure block, the other end of the connecting rod being hinged to the eccentric position of the turntable, and the rotating shaft two at the center of the turntable being connected to the flipping mechanism via a pulley two.

[0018] Preferably, the drying mechanism includes an air bladder disposed inside the guide sleeve. The upper and lower ends of the air bladder are respectively connected to the lower surface of the sliding pressure block and the bottom of the guide sleeve. The air bladder is connected to a heat source through an air inlet pipe and to the arc plate through an exhaust pipe assembly. The air outlets of the exhaust pipe assembly are evenly distributed on the inner surface of the arc plate. A one-way air inlet valve is provided on the air inlet pipe, and a one-way air outlet valve is provided on the pipe of the exhaust pipe assembly.

[0019] Preferably, the heat source is the heat dissipation from the surface of the agricultural machinery's engine.

[0020] Preferably, the oscillating filter plate is provided with a row of cutters on the side facing the coarse material chamber, and the cutters are arranged close to the inner wall of the material receiving cylinder.

[0021] Preferably, the two sides of the oscillating filter plate are provided with sliding grooves along the radial direction of the material receiving cylinder, and the guide block provided at the lower end of the folded connecting rod is slidably installed in the sliding groove.

[0022] The present invention has the following advantages:

[0023] (1) The device of the present invention, through the cooperation of the turning mechanism, the feeding mechanism and the drying mechanism, allows the plant straw and stubble to enter the receiving cylinder for further screening after initial crushing. It not only distinguishes between coarse and fine materials by the up and down swing of the swinging filter plate, but also further divides the coarse material in the coarse material chamber into light coarse material that is easy for soil nutrients to absorb and heavy coarse material that is difficult for the soil to absorb. The swinging filter plate can promote further crushing of light coarse material in the coarse material chamber during the upward swing, thereby improving the crushing efficiency of crop straw and stubble. Fine material is discharged into the planting zone, while heavy coarse material is discharged into the inter-plant zone. Thus, the nutrient zone is divided during the process of crop turning back into the field, which is conducive to improving the subsequent absorption efficiency of nutrients by the soil and seeds.

[0024] (2) Furthermore, the drying mechanism of the present invention disturbs the fine material while drying it to promote its relatively uniform distribution; due to the angle setting of the swing filter plate and the arc plate, the heat flow can break through the swing filter plate to back-blow and dry the coarse material, thereby forming a layer of light coarse material and heavy coarse material distributed on the upper and lower sides, so as to distinguish the coarse material, and only the heavy coarse material located in the coarse material cavity is discharged from the coarse material outlet, while the light coarse material is left for further processing, thereby improving the utilization rate;

[0025] When not in a drying state, it can promote the automatic replenishment of heat by the airbags, spontaneously reduce the heat of the agricultural machinery engine, and improve the heat conversion efficiency.

[0026] (3) At the same time, the swinging of the swinging filter plate of the present invention can not only promote the shaking and dropping of crushed straw and stubble, but also prevent the screen hole from being blocked and the material inside the material receiving cylinder from being blocked by the airflow back blowing on the surface of the swinging filter plate and the scraping of the arc plate relative to the material receiving cylinder, thus improving the smoothness of the device operation.

[0040] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0041] like Figures 1 to 7As shown, the present invention provides an auxiliary device for crop rotation between strips, including a frame 1, a turning and pressing mechanism 2, a material guiding screen plate 3, a feeding mechanism 4, a pressing roller 5, and a drying mechanism 6.

[0042] The frame 1 is connected to the agricultural machinery using a rear-mounted design. The frame 1 includes two symmetrically arranged main plates 101. The turning and pressing mechanism 2, the guide screen plate 3, and the feeding mechanism 4 are all installed between the main plates 101. A housing 102 is located above the main plates 101, and a baffle plate 103 is installed on the side of the housing 102 facing the agricultural machinery. The housing 102 and the baffle plate 103 prevent crop debris and clay from being splashed out after being crushed in the crushing chamber.

[0043] The compaction mechanism 2 is used to crush crop straw and stubble and return them to the field. Specifically:

[0044] The flipping and pressing mechanism 2 includes a cutter roller 201 rotatably mounted between the main plates 101. The cutter roller 201 has several rows of spirally arranged, overlapping, and staggered Y-shaped moving blades 202 on its circumference. The Y-shape of the moving blades is designed to effectively and firmly cut the crop stalks and rootstock laterally. The Y-shaped moving blades 202 are connected to the cutter roller 201 via moving blade pins 203. The Y-shaped moving blades 202 can both revolve around the cutter roller 201 and rotate around the moving blade pins 203. This allows the Y-shaped moving blades 202 to automatically rotate and avoid hard objects such as stones.

[0045] The inner wall of the crushing chamber of the frame 1 is equipped with a fixed blade plate 204, and the Y-shaped moving blade 202 can pass through the fixed blade plate 204 during rotation. The fixed blade plate 204 and the Y-shaped moving blade 202 work together to shear and crush crop straw and stubble.

[0046] The cutter roller 201 is connected to a rotating shaft 205 parallel to the cutter roller 201 via a pulley 206. The other end of the rotating shaft 205 extends to the middle of the frame 1 and is driven to rotate by a gear transmission mechanism 207. The power comes from the power output shaft of the agricultural machinery. The power is transmitted to the gear transmission mechanism 207 through the power output shaft, which drives the rotating shaft 205 to rotate. The cutter roller 201, which is connected to the rotating shaft 205 via the pulley 206, also rotates to complete the crushing operation.

[0047] In the process of crushing straw, corn stalks, etc., not only are the straws cut, but a lot of soil is also brought up. Therefore, a guide screen plate 3 is specially set up to separate the soil and crop debris raised by the turning and pressing mechanism 2.

[0048] The guide screen plate 3 is an arc-shaped screen plate, with its bottom surface tangent to the horizontal plane. The lower arc of the screen plate extends to the opening above the receiving cylinder 401. In this way, heavier soil and debris will settle at the bottom of the guide screen plate 3 and fall through the screen holes to the outside of the receiving cylinder 401, while lighter crop debris will accumulate on the surface of the guide screen plate 3 and fall along the arc into the receiving cylinder 401.

[0049] The feeding mechanism 4 includes a feeding cylinder 401 that receives crop debris at the top. Several fine material inlets 402 are equidistantly arranged at the bottom of the feeding cylinder 401, and several coarse material inlets 403 are arranged on both sides of the feeding cylinder 401, alternating with the fine material inlets 402. Two oscillating filter plates 404 are symmetrically hinged to the cylinder shaft of the feeding cylinder 401, forming a fine material cavity 10 between the two oscillating filter plates 404. A coarse material cavity 20 is formed above the oscillating filter plates 404. An arc plate 405, which is in contact with the inner wall of the feeding cylinder 401, is provided on the side of the oscillating filter plate 404 facing the fine material cavity 10. The arc length of the arc plate 405 is greater than the corresponding diameter of the coarse material inlets 403. The oscillating filter plates 404 are driven by a power mechanism to oscillate up and down on a horizontal plane. Specifically:

[0050] The power mechanism includes a guide sleeve 407 vertically mounted on the frame 1. The guide sleeve 407 passes through the middle of the material receiving cylinder 401. An arc-shaped guide plate 406 is provided on the top of the guide sleeve 407. The inner ends of the swing filter plate 404 are hinged to both sides of the guide sleeve 407. A sliding pressure block 408 is slidably mounted on the guide sleeve 407.

[0051] The two sides of the sliding pressure block 408 are slidably connected to the side ends of the swing filter plate 404 via a folded connecting rod 409. Specifically, the two sides of the swing filter plate 404 are provided with sliding grooves 410 along the radial direction of the material receiving cylinder 401, and the guide block 411 provided at the lower end of the folded connecting rod 409 is slidably installed in the sliding grooves 410.

[0052] A connecting rod 414 is hinged to the sliding pressure block 408. The other end of the connecting rod 414 is hinged to the eccentric position of the turntable 415. The rotating shaft 412 at the center of the turntable 415 is connected to the flipping mechanism 2 through the pulley 413.

[0053] During operation, the rotating shaft 412, which is connected to the cutter roller 201 via the pulley 413, drives the turntable 415 to rotate around the shaft, thereby causing the sliding pressure block 408, which is connected to the connecting rod 414, to move up and down along the guide sleeve 407. The folded connecting rod 409 installed on the sliding pressure block 408 drives the swing filter plate 404, which is limited by the guide block 411 at its end, to swing up and down along the hinge axis between the swing filter plate 404 and the guide sleeve 407.

[0054] When the far end of the swing filter plate 404 swings downward, the arc plate 405 no longer covers the coarse material inlet 403; when the far end of the swing filter plate 404 swings upward, the arc plate 405 covers the coarse material inlet 403, and no material is discharged from the coarse material inlet 403. Throughout the entire process, the fine material inlet 402 remains open.

[0055] A row of cutters 416 is arranged on the side of the oscillating filter plate 404 facing the coarse material chamber 20, and the cutters 416 are arranged close to the inner wall of the receiving cylinder 401. The cutters 416 can further cut the crop debris on the inner wall of the receiving cylinder 401.

[0056] The drying mechanism 6 is located inside the receiving cylinder 401 and is used to dry the crop debris before it is discharged. Specifically:

[0057] The drying mechanism 6 includes an airbag 601 disposed inside the guide sleeve 407. The upper and lower ends of the airbag 601 are respectively connected to the lower surface of the sliding pressure block 408 and the bottom of the guide sleeve 407. The airbag 601 is connected to a heat source through an air inlet pipe 602, which can dissipate heat from the surface of the agricultural machinery's engine.

[0058] The airbag 601 is connected to the arc plate 405 via an exhaust pipe assembly 603. The air outlets 604 of the exhaust pipe assembly 603 are evenly distributed on the inner surface of the arc plate 405. A one-way intake valve (not shown in the figure) is provided on the intake pipe 602, and a one-way exhaust valve (not shown in the figure) is provided on the exhaust pipe assembly 603. When the sliding pressure block 408 moves relative to the guide sleeve 407, it can change the volume of the airbag 601.

[0059] The trowel roller 5 is used to compact the soil that has been turned over and returned to the field. During its forward movement, the trowel roller 5 compacts the areas it passes over (including soil and crop debris), and the compaction by the trowel roller 5 prevents the soil from becoming too loose.

[0060] The working principle of the device of this invention is as follows:

[0061] The power output shaft of the agricultural machinery drives the cutter roller 201 and the swing filter plates 404 on both sides of the material receiving cylinder 401 to swing up and down.

[0062] When the cutter roller 201 rotates, the Y-shaped moving blade 202 connected to the cutter roller 201 can effectively and firmly grab the crop straw on the bottom surface during the rotation process, and cut the crop stubble and roots in the direction of rotation. The cut crop straw, stubble, and soil are lifted onto the inclined guide screen plate 3. As the guide screen plate 3 shakes, small-diameter soil particles are filtered from the surface of the guide screen plate 3, while larger-diameter straw and stubble will fall along the guide screen plate 3 along the arc-shaped guide plate 406 into the receiving cylinder 401.

[0063] During the oscillation of the oscillating filter plate 404, the drying of crop straw and stubble is accelerated, as well as the separation of coarse and fine materials. Fine materials fall from the filter holes of the oscillating filter plate 404 into the fine material chamber 10 below, while coarse materials are retained in the coarse material chamber 20. It should be noted that the proportion of coarse materials in the crop straw and stubble crushed by the cutter roller 201 is relatively low. This proportion can be achieved by configuring factors such as the density and rotation speed of the cutter roller 201, limiting the diameter of the coarse materials, and controlling the oscillation amplitude of the oscillating filter plate 404, thereby preventing clogging of the oscillating filter plate 404 during the screening process.

[0064] Fine feed and coarse feed are returned to the field alternately through fine feed inlet 402 and coarse feed inlet 403, respectively. Specifically:

[0065] 1. When the sliding block 408 moves upward along the guide sleeve 407:

[0066] On the one hand, the far end of the swing filter plate 404 rotates upward, and the arc plate 405 connected to it will gradually block the coarse material inlet 403, thereby closing the coarse material inlet 403 and providing time for further processing of the coarse material in the coarse material chamber 20.

[0067] The fine material in the fine material chamber 10 is discharged normally along the fine material outlet 402. The falling fine material will fall into the planting belt 30. The material discharged from this part is fine and easily absorbed by the soil, and will not affect the planting of subsequent crops.

[0068] As the oscillating filter plate 404 moves upward, the cutter 416 at the upper end of the oscillating filter plate 404 will further crush the coarse material in the coarse material chamber 20. The crushed fine material can enter the fine material chamber 10 along the oscillating filter plate 404, thereby improving the utilization rate of fine material.

[0069] On the other hand, during the upward movement of the sliding block 408, the volume of the airbag 601 increases, and the previously emptied airbag 601 is replenished with temporarily stored hot air from the intake pipe 602 for subsequent use. This method reduces engine heat while effectively utilizing this heat for drying coarse and fine materials, and enables automatic gas discharge and replenishment, simplifying the device while improving energy efficiency.

[0070] 2. When the sliding block 408 moves downward along the guide sleeve 407:

[0071] On one hand, the sliding pressure block 408 compresses the air bladder 601, and the hot air temporarily stored in the air bladder 601 will be discharged from the air outlet 604 of the arc plate 405 through the exhaust pipe assembly 603. This dries the fine material in the fine material chamber 10. Also, due to the disturbance of the hot air, the flow of fine material in the fine material chamber 10 can be promoted, making the distribution of fine material more uniform, which is conducive to improving the uniformity of material discharge at the fine material outlet 402.

[0072] Furthermore, as the two oscillating filter plates 404 approach each other, the fine material in the squeezed fine material chamber 10 is discharged along the fine material inlet 402.

[0073] Because the oscillating filter plate 404 and the corresponding arc plate 405 are approximately at an acute angle, the hot air discharged from the air outlet 604 will also pass through the oscillating filter plate 404 to dry the coarse material on it. Under the influence of the upward airflow formed by the oscillating filter plate 404, the lighter "light coarse material" in the coarse material will be blown away from the surface of the oscillating filter plate 404, while the heavier "heavy coarse material" will accumulate on the surface of the oscillating filter plate 404, forming a layer with the "light coarse material" above. When the arc plate 405 connected to the oscillating filter plate 404 rotates to expose the coarse material outlet 403, the oscillating filter plate 404 rotates to tilt downwards towards the end facing the coarse material outlet 403. The lower layer of "heavy coarse material" is discharged from the coarse material outlet 403 to the intercropping zone 40, bringing secondary nutrients to the farmland and achieving full return of nutrients to the crop. The upper "light coarse material" can be temporarily stored in the coarse material chamber 20 and further crushed into fine material by the cutter 416. The "heavy coarse material" and fine material are like... Figure 7 As shown, the plants fall into the alternating inter-species zone 40 and planting zone 30, which allows for differentiated return to the field according to local conditions, avoiding the impact on crop growth due to the difficulty in absorbing coarse feed.

[0074] Finally, as the 5th roller rolls over the ground, it compacts the soil, completing the process of turning the crop back into the field.

[0075] In summary, the device of the present invention, through the cooperation of mechanisms such as the turning and pressing mechanism 2, the feeding mechanism 4, and the drying mechanism 6, allows plant straw and stubble to be further screened in the receiving cylinder 401 after initial crushing. It not only distinguishes between coarse and fine materials through the up-and-down swinging of the oscillating filter plate 404, but also, in conjunction with the drying mechanism 6, further divides the coarse material in the coarse material chamber 20 into light coarse material that is easily absorbed by the soil and heavy coarse material that is difficult for the soil to absorb. The upward swinging of the oscillating filter plate 404 promotes further crushing of the light coarse material in the coarse material chamber 20, improving the crushing efficiency of crop straw and stubble. Fine material is discharged into the planting zone 30, while heavy coarse material is discharged into the inter-species zone 40. Thus, during the process of turning the crop back into the field, nutrient zones are divided, which is beneficial to improving the subsequent absorption efficiency of nutrients by the soil and seeds.

[0076] Furthermore, the drying mechanism 6 of the present invention simultaneously agitates the fine material during drying to promote a relatively uniform distribution of the material; due to the angle setting of the oscillating filter plate 404 and the arc plate 405, the heat flow can break through the oscillating filter plate 404 to back-blow and dry the coarse material, thereby forming a layer of light coarse material and heavy coarse material distributed vertically, so as to distinguish the coarse material, allowing only the heavy coarse material located in the coarse material cavity 20 to be discharged from the coarse material port 403, while leaving the light coarse material for further processing, thereby improving the utilization rate;

[0077] When not in a drying state, it can promote the automatic replenishment of heat by the airbag 601, spontaneously reduce the heat of the agricultural machinery engine, and improve the heat conversion efficiency.

[0078] Meanwhile, the oscillation of the oscillating filter plate 404 of the present invention can not only promote the shaking and dropping of crushed straw and stubble, but also prevent the screen hole from being blocked and the material from sticking inside the material receiving cylinder 401 by the backflow of air on the surface of the oscillating filter plate 404 and the scraping of the arc plate 405 relative to the material receiving cylinder 401, thus improving the smoothness of the device operation.

[0079] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
