Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and particularly relates to a strip tiller for agriculture. Background Art

[0002] Strip tillage refers to tilling between planting rows while retaining the soil structure between crop rows, reducing the tillage of the entire field. Strip tillage can reduce soil erosion because only part of the area is tilled, crop residues are retained, organic matter is increased, and the soil structure is improved. Additionally, it helps with water retention and reduces water evaporation because the residues cover the ground.

[0003] When the existing strip tiller is in use, the outside of the cutter head is prone to being wound by straw, making it difficult to clean in a timely manner, thus affecting the depth of soil loosening and resulting in a decline in tillage quality; secondly, stones or metal parts dropped in the farmland are likely to get stuck between the cutter heads. If the stones and metal parts are not cleaned in a timely manner, it will accelerate the wear and deformation of the cutter heads. Summary of the Invention

[0004] The purpose of the present invention is to provide a strip tiller for agriculture to solve the problems in the prior art that the outside of the cutter head is prone to being wound by straw, making it difficult to clean in a timely manner, thus affecting the depth of soil loosening and resulting in a decline in tillage quality; secondly, stones or metal parts dropped in the farmland are likely to get stuck between the cutter heads. If the stones and metal parts are not cleaned in a timely manner, it will accelerate the wear and deformation of the cutter heads.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A strip tiller for agriculture, including a machine body, a main shaft installed inside the machine body, and a plurality of strip tillage mechanisms installed outside the main shaft. The strip tillage mechanism includes:

[0006] A fixed cylinder, which is installed on the main shaft;

[0007] A tillage component, which is installed outside the fixed cylinder and has multiple groups. The tillage component includes a plurality of cutter heads arranged along the length direction of the fixed cylinder;

[0008] A fixed-point impurity removal component, which includes a guide plate slidably sleeved outside a plurality of cutter heads in the same tillage component and an active adjustment component for driving the guide plate to move;

[0009] A directional export component, which includes a receiving plate and a conveying component arranged at one end of the receiving plate.

[0010] Further, the multiple groups of tillage components are arranged in a circular array centered on the main shaft, and the cutter heads in the multiple groups of tillage components are arranged in an alternating manner.

[0011] Further, the active adjustment component includes fixing plates arranged at both ends of the fixed cylinder and fixing bars respectively fixed on the outer walls of the opposite sides of the two fixing plates;

[0012] The top of the fixing plate is fixedly connected to the inner wall of the top of the body;

[0013] Both ends of the material guide plate are rotatably connected with driven rods.

[0014] Furthermore, the fixing bar is a semi-elliptical structure, and when the fixing cylinder rotates, the driven rod is driven to move along the top of the fixing bar.

[0015] Furthermore, a reset component is installed on the outer wall of the guide plate near the fixed cylinder, and the reset component includes a sleeve fixed to the inside of the fixed cylinder, a slider slidably connected to the inside of the sleeve, and a linkage rod fixed to the outer wall of one side of the guide plate;

[0016] The other end of the linkage rod extends to the inside of the sleeve and is fixedly connected to the outer wall of one side of the slider. A spring is fixedly connected to the outer wall of the other side of the slider, and the other end of the spring is fixedly connected to the inner wall of the sleeve.

[0017] Furthermore, a plurality of scraping grooves are provided inside the material guide plate, and the cutter head is located inside the scraping grooves.

[0018] Furthermore, the conveying component includes a material receiving shell installed inside the machine body and an auger installed inside the material receiving shell;

[0019] A material discharge port is provided at one end of the material receiving shell, and the material discharge port faces the area between two adjacent strip tillage mechanisms.

[0020] Furthermore, one end of the receiving plate close to the receiving shell is tilted downward and fixed with a fixing rod, and the fixing rod is fixed to the inner wall of the receiving shell;

[0021] The other end of the receiving plate is provided with a plurality of adapting grooves, and the adapting grooves are used for passing the cutter head.

[0022] Compared with the prior art, the agricultural tillage machine provided by the present invention has the following beneficial effects:

[0023] After the same group of cutter heads loosen the soil, and the guide plate outside the cutter heads rotates to the fixed bar area, the driven rod starts to move along the top of the fixed bar, thereby driving the guide plate to move upward along the outside of the cutter heads, and pushing the straw wrapped around the outside of the cutter heads, the stones or metal parts stuck between two adjacent cutter heads upward. When the cutter heads rotate to face vertically upward, the guide plate moves up to the top of the cutter heads, so that the straw, stones or metal parts are completely separated from the cutter heads, avoiding the problem that the straw wrapped around the outside of the cutter heads is difficult to clean in time and affects the loosening quality, and solving the problem that the stones or metal parts stuck between the cutter heads are not cleaned in time, which easily causes the cutter heads to be worn and deformed, thereby playing a role in protecting the cutter heads;

[0024] After the straw and stones reach the top of the receiving plate, they slide down along the top of the receiving plate into the inside of the material receiving shell. By driving the auger to rotate, the straw and stones are conveyed to the area without soil loosening between two adjacent strip tillage mechanisms. Through the directional conveyance of the stones and metal parts, it is convenient for agricultural personnel to clean the stones and metal parts, reducing the probability of damage to other agricultural machinery caused by the stones or metal parts.

[0034] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will further introduce the present invention in detail in conjunction with the drawings.

[0035] Embodiment: Please refer to Figure 1 - Figure 6, A strip tillage machine for agriculture, comprising a machine body 1, a main shaft 2 installed inside the machine body 1, and a plurality of strip tillage mechanisms installed outside the main shaft 2. The distance between adjacent two strip tillage mechanisms is the same. Driven wheels can also be provided at both ends of the machine body 1 to facilitate the movement of the machine body 1 on the ground. Both the main shaft 2 and the machine body 1 are connected to an agricultural machinery driving device, which can drive the movement of the machine body 1 and drive the rotation of the main shaft 2. The strip tillage mechanism includes:

[0036] A fixed cylinder 3, which is installed on the main shaft 2;

[0037] A tillage component, which is installed outside the fixed cylinder 3 and is provided with multiple groups. The tillage component includes a plurality of cutter heads 4 arranged along the length direction of the fixed cylinder 3. The multiple groups of tillage components are distributed in a circular array centered on the main shaft 2, and the cutter heads 4 in the multiple groups of tillage components are staggered with each other;

[0038] When the main shaft 2 rotates, it drives each cutter head 4 to rotate through the fixed cylinder 3 to perform soil loosening work, and the cutter head 4 rotates towards the material receiving shell 15.

[0039] A fixed-point impurity removal component, which includes a guide plate 5 slidably sleeved outside multiple cutter heads 4 in the same tillage component and an active adjustment component for driving the movement of the guide plate 5. A plurality of scraping grooves 14 are formed inside the guide plate 5, and the cutter heads 4 are located inside the scraping grooves 14. The active adjustment component includes fixing plates 7 provided at both ends of the fixed cylinder 3 and fixing bars 8 respectively fixed on the outer walls of the opposite sides of the two fixing plates 7; the top of the fixing plate 7 is fixedly connected to the inner wall of the top of the machine body 1; driven rods 9 are rotatably connected to both ends of the guide plate 5, and a reset component is also installed on the outer wall of the guide plate 5 close to the fixed cylinder 3. The reset component includes a sleeve 10 fixed inside the fixed cylinder 3, a slider 11 slidably connected inside the sleeve 10, and a linkage rod 12 fixed on the outer wall of one side of the guide plate 5; the other end of the linkage rod 12 extends into the sleeve 10 and is fixedly connected to the outer wall of one side of the slider 11. A spring 13 is fixed on the outer wall of the other side of the slider 11, and the other end of the spring 13 is fixedly connected to the inner wall of the sleeve 10. The fixing bar 8 is of a semi-elliptical structure. When the fixed cylinder 3 rotates, it drives the driven rod 9 to move along the top of the fixing bar 8;

[0040] After the same set of cutter heads 4 loosen the soil, and when the material guide plate 5 outside the cutter head 4 rotates to the area of the fixed strip 8, the driven rod 9 starts to move along the top of the fixed strip 8, thereby driving the material guide plate 5 to move upward along the outside of the cutter head 4. The linkage rod 12 moves accordingly, and the spring 13 is stretched, pushing the straw wound around the outside of the cutter head 4 or the stones stuck between two adjacent cutter heads 4 upward. When the cutter head 4 rotates to the vertical upward position, the material guide plate 5 moves up to the top of the cutter head 4, so that the straw and stones are completely separated from the cutter head 4. Then, as the cutter head 4 continues to rotate, due to the gravitational action of the straw and stones themselves and the centrifugal action generated by the rotation of the material guide plate 5, the straw and stones at the top of the material guide plate 5 are transported onto the receiving plate 6. As the cutter head 4 continues to rotate, and through the resilience of the spring 13, it drives the material guide plate 5 to move along the outside of the cutter head 4 towards the direction of the fixed cylinder 3. Before the cutter head 4 re-enters the soil interior, it drives the material guide plate 5 to fit against the outer wall of the fixed cylinder 3.

[0041] The directional export component includes a receiving plate 6 and a conveying component arranged at one end of the receiving plate 6. The conveying component includes a material receiving shell 15 installed inside the machine body 1 and an auger 16 installed inside the material receiving shell 15. One end of the auger 16 is connected to a motor for driving the auger 16 to rotate; an outlet is opened at one end of the material receiving shell 15, and the outlet faces the area between two adjacent strip tillage mechanisms. One end of the receiving plate 6 close to the material receiving shell 15 is inclined downward, and a fixed rod 17 is fixedly connected, and the fixed rod 17 is fixedly connected to the inner wall of the material receiving shell 15; a plurality of fitting grooves 18 are opened at the other end of the receiving plate 6, and the fitting grooves 18 are used for passing the cutter head 4.

[0042] After the straw and stones reach the top of the receiving plate 6, they slide down along the top of the receiving plate 6 into the material receiving shell 15. By driving the auger 16 to rotate, the straw and stones are transported to the area between two adjacent strip tillage mechanisms that do not need to be loosened, so as to facilitate agricultural personnel to clean the stones or even metal parts, and reduce the probability of damage to other agricultural machinery caused by stones or metal parts.

[0043] Working principle: When in use, when the main shaft 2 rotates, it drives each cutter head 4 to rotate through the fixed cylinder 3 to carry out soil loosening work. After the same group of cutter heads 4 loosen the soil and when the guide plate 5 outside the cutter head 4 rotates to the area of the fixed strip 8, the driven rod 9 starts to move along the top of the fixed strip 8, thereby driving the guide plate 5 to move upward along the outside of the cutter head 4. The linkage rod 12 moves accordingly, and the spring 13 is stretched, pushing the straw wound around the cutter head 4 or the stones stuck between two adjacent cutter heads 4 upward. When the cutter head 4 rotates to the vertical upward position, the guide plate 5 moves up to the top of the cutter head 4, so that the straw and stones are completely separated from the cutter head 4. Then, with the continuous rotation of the cutter head 4, through the gravity of the straw and stones themselves and the centrifugal force generated by the rotation of the guide plate 5, the straw and stones at the top of the guide plate 5 are conveyed onto the receiving plate 6. After the straw and stones reach the top of the receiving plate 6, they slide along the top of the receiving plate 6 into the inside of the material receiving shell 15. By driving the rotating auger 16, the straw and stones are conveyed to the area that does not need to be loosened between two adjacent strip tillage mechanisms, so as to facilitate agricultural personnel to clean the stones or even metal parts, and reduce the probability of damage to other agricultural machinery caused by the stones or metal parts. With the continuous rotation of the cutter head 4 and through the resilience of the spring 13, the guide plate 5 is driven to move along the outside of the cutter head 4 towards the direction of the fixed cylinder 3. Before the cutter head 4 re-enters the soil interior, the guide plate 5 is driven to fit against the outer wall of the fixed cylinder 3.
