Description

Technical Field

[0001] The invention relates to the technical field of agricultural equipment, in particular to tillage equipment for wheat planting. Background Art

[0002] Traditional vertical-axis rotary tillers are suitable for light soils, but perform poorly on heavy soils or plots with a lot of rocks. Frequent hard collisions will increase the wear of the cutter and even cause mechanical failures. In addition, during the high-speed rotation of the cutter, soil will be blown away, posing certain safety hazards.

[0003] Shovel tillage does not violently turn over the soil, does not disrupt the tillage layer, and better preserves the surface root stubble vegetation. The original ridge operation does not cause serious damage to the original soil layer, thus maintaining the organic matter in the original soil layer, which is beneficial to the growth of crops.

[0004] The existing application number is CN201710791779.7, which discloses a method of controlling the rotation of a soil shovel around a horizontal axis to scoop up and deliver soil, replacing traditional high-speed rotating cutters and reducing safety hazards during the use of the equipment. Specifically, the tractor output shaft drives the output shaft of the reducer to rotate, the reducer drives the crank assembly to rotate, the crank assembly drives the connecting rod assembly to reciprocate in the same plane, the connecting rod assembly drives the rocker assembly to swing, and the soil shovel moves in an inverted raindrop-shaped curve when the connecting rod assembly reciprocates. The movement trajectory of the soil shovel is determined by the design dimensions of the connecting rod assembly, the rocker assembly, the crank assembly and the connecting plate of the actuator; the process of the soil shovel from point O to point A is within the quick return characteristic range of the crank rocker mechanism; the process of the soil shovel from point B to point O is the process of the soil shovel entering the soil; the reciprocating motion of the connecting rod assembly drives the soil shovel to complete the cycle of "entering the soil - shoveling the soil - delivering the soil - return stroke", thereby achieving the purpose of loosening the soil and tilling.

[0005] However, when using the technical solution in the above-mentioned patent document, although a large number of shovels are used to shovel the soil, in the northwest region, due to the lack of organic matter in the soil and the low precipitation, the soil is prone to compaction. When using the shovel for excavation, the excavated soil will still remain in a block shape, which is difficult to effectively break, resulting in low tillage efficiency; in addition, the rotation center of the shovel is relatively high relative to the ground. When the shovel makes a curved motion, the swing angle range of the shovel head position is small, and the range of action on the surface is relatively limited, which in turn affects its shoveling ability. Therefore, the present application provides a tillage equipment for wheat planting. Summary of the invention

[0006] To solve the deficiencies in the above-mentioned existing technologies, the purpose of the present invention is to provide a tilling device for wheat planting. The rotation center of the shovel body structure of this device is close to the ground. With the periodic operation of the shovel body structure, the position of the shovel head can act on the soil on the ground surface in a large range, with strong soil shoveling ability. On this basis, the shoveled soil is effectively broken, improving the tilling efficiency for the easily compacted soil in the northwest region.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows:

[0008] A tilling device for wheat planting is provided, including a vehicle body connection component and a plurality of turning shovel components installed on the vehicle body connection component. The vehicle body connection component includes a traction platform and a transverse frame. The traction platform is connected to a power device, and the turning shovel components are connected to the traction platform through reinforcement arms. A plurality of cross arms and soil block cutting edges are fixedly installed in the transverse frame, and a plurality of bearing bushes are arranged at intervals on the cross arms.

[0009] The turning shovel component includes an L-shaped seat, a rocker arm, a sleeve, and a shovel handle; the L-shaped seat is detachably and fixedly installed at the bottom of the reinforcement arm. A support frame Ⅰ is fixedly installed on the side of the L-shaped seat. A rotating shaft is fixedly installed on the rocker arm, and the support frame Ⅰ is rotationally connected with the rotating shaft in an embedded manner. A sliding pin Ⅰ is fixedly installed on the side of the sleeve, and the sliding pin Ⅰ is rotationally connected with the rocker arm. The shovel handle is fixedly installed in the sleeve. A shovel is provided at the end of the shovel handle, and the shovel handle penetrates through a spherical shaft and is slidably connected with the spherical shaft. The spherical shaft is rotationally installed in the bearing bush in an embedded manner.

[0010] In this application, for the rotation control method of the rocker arm, an optional technical solution is: the rocker arms on a plurality of turning shovel components rotate at the lower ends of their respective corresponding L-shaped seats. Using a high-torque low-speed motor as the power source, the power is transmitted through a transmission shaft, and then synchronous control is carried out in cooperation with a pulley group. Parameters such as the diameter of each pulley, the groove specifications of the pulley, and the tension of the belt are adjusted according to the tilling terrain conditions.

[0011] In this application, for the rotation control method of the rocker arm, another optional technical solution is: the rotation of the rocker arms on a plurality of turning shovel components at the lower ends of their respective corresponding L-shaped seats is independently controlled; a support frame Ⅱ is fixedly installed on the side of the support frame Ⅰ away from the sleeve. A rotation driver is installed on the support frame Ⅱ, and the output shaft of the rotation driver is connected to the rotating shaft. The parameter model of the rotation driver is adjusted according to the tilling terrain conditions.

[0012] Further, a limiting edge is fixedly installed at the bottom of the L-shaped seat, and the rotating shaft penetrates through the limiting edge; defining the traveling direction of the power device as the front, a convex structure is integrally formed on the limiting edge, and the convex structure extends downward and forward of the limiting edge; the rocker arm is connected to the sliding pin Ⅰ through a tightening arm. The sliding pin Ⅰ is rotationally connected with the tightening arm and slidably connected with a chute Ⅰ on the rocker arm. The tightening arm is slidably installed in the middle of the rocker arm and penetrates through both ends of the rocker arm.

[0013] On both sides of the pressing arm, a sliding pin II and a column are respectively fixedly connected. The sliding pin II and the column are respectively slidably connected with the fixed ears and the sliding groove II on both sides of the rocker arm. An I-shaped structure is arranged at the end of the sliding pin II, and the I-shaped structure is embedded with the limiting circumferential edge and abuts against the inner side surface of the limiting circumferential edge. A spring is sleeved outside the column, and both ends of the spring are fixedly connected with the fixed ear and the pressing arm respectively.

[0014] Furthermore, a feeding component is installed on the traction table. The feeding component includes a feeding tank. The feeding tank is fixedly installed in the middle of the end of the traction table. A plurality of feeding ports are arranged at the bottom of the feeding tank, and the feeding ports are located above the cutting edges of the soil blocks.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. For the tillage equipment for wheat planting according to the example of the present invention, the bearing bush is arranged on the transverse frame and is relatively close to the ground. The shaking and rotating angle range of the shovel handle is relatively large. With the periodic shaking of the shovel handle, the shovel can act on the soil on the ground surface in a large range, and the soil shoveling ability is strong. In addition, due to the relatively large shaking and rotating angle range of the shovel handle, after the soil is shoveled up by the shovel, it can present an overall state tending to be horizontal as shown in the figure. In this way, under the action of the moving inertia of the shovel, the soil shoveled up by the shovel can be vertically thrown towards the cutting edges of the soil blocks. When this part of the soil passes through the cutting edges of the soil blocks, it is cut by the interception of the cutting edges of the soil blocks, achieving the purpose of effectively crushing the shoveled soil, and is suitable for the soil conditions in the northwest region where the soil is prone to hardening.

[0017] 2. For the tillage equipment for wheat planting according to the example of the present invention, a limiting circumferential edge is fixedly installed at the bottom of the L-shaped seat, and a convex structure is integrally formed on the limiting circumferential edge; during the shaking process of the shovel handle, corresponding points a, a, b, b, c, and c are respectively formed at the center and the edge of the shovel; when the shovel transitions from point a to point c, under the limiting action of the limiting circumferential edge, the pressing arm pulls the sliding pin I to move towards the end of the rocker arm, so that the shovel handle moves upward by a certain distance at the spherical shaft, and the shovel tends to be erected, optimizing the action angle when the shovel shovels the soil on the ground surface and strengthening the soil shoveling ability of the shovel.

[0018] 3. For the tillage equipment for wheat planting according to the example of the present invention, with the operation of the power equipment, under the action of gravity, the soil in the feeding tank falls on the tilled ground surface after passing through the cutting edges of the soil blocks, improving the physical properties, biological activity and chemical composition of the soil. In addition, because the soil in the feeding tank can be more evenly spread on the ground surface after being cut and dispersed by the cutting edges of the soil blocks, the porosity of the soil is increased, and the air permeability and water permeability of the soil are improved, which is helpful for the healthy growth of crop roots.

[0019] 4. For the tilling equipment for wheat planting according to the example of the present invention, when the rotation driver is started to drive the respective corresponding rotating shafts to rotate, since the rotations of the multiple rocker arms are independently controlled, the reaction forces generated when the multiple shovels act on the ground will not be fed back to the entire equipment at the same time, avoiding the problem of loosening at the joints of the equipment components caused by resonance.

[0020] 5. For the tilling equipment for wheat planting according to the example of the present invention, the shovels act concentratedly on the shallow soil on the ground surface, without disturbing the tillage layer, better retaining the surface root stubble vegetation. During the original ridge operation, the original soil layer structure will not be severely damaged, which is beneficial to the growth of crops. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Embodiment 1:

[0039] As Figure 1 、 Figure 2 and Figure 3 shown, this embodiment provides a tilling device for wheat planting, including a vehicle body connecting component 1 and a plurality of turning shovel components 2 installed on the vehicle body connecting component 1. The vehicle body connecting component 1 includes a traction platform 11 and a transverse frame 12. The traction platform 11 is connected to the power equipment, and the turning shovel component 2 is connected to the traction platform 11 through a reinforcing arm 17. A plurality of cross arms 13 and soil block cutting edges 16 are fixedly installed inside the transverse frame 12, and a plurality of bearing bushes 14 are arranged on the cross arms 13.

[0040] Among them, the power equipment can be selected from agricultural tractors such as John Deere agricultural tractors, Dongfanghong tractors, Zoomlion heavy machinery tractors, wheeled tractors, crawler tractors, and walking tractors, and is specifically selected according to the number of turning shovel components 2 and the tillage area at the same time.

[0041] As Figure 3 shown, a spherical groove is integrally formed in the middle of the shovel 25, and the spherical groove is used to increase the amount of soil that the shovel 25 can hold. A plurality of shovel teeth 251 are arranged at the end of the shovel 25.

[0042] As Figure 4 and Figure 6 shown, the turning shovel component 2 includes an L-shaped seat 21, a rocker arm 22, a sleeve 23, and a shovel handle 24; the L-shaped seat 21 is detachably installed at the bottom of the reinforcing arm 17, a support frame I 212 is fixedly installed on the side of the L-shaped seat 21, a rotating shaft 221 is fixedly installed on the rocker arm 22, and the support frame I 212 is rotationally connected with the rotating shaft 221 in an embedded manner. A sliding pin I 231 is fixedly installed on the side of the sleeve 23, the sliding pin I 231 is rotationally connected with the rocker arm 22, the shovel handle 24 is installed inside the sleeve 23, a shovel 25 is provided at the end of the shovel handle 24, the shovel handle 24 passes through the spherical shaft 15 and is slidably connected with the spherical shaft 15, and the spherical shaft 15 is rotationally installed in the bearing bush 14 in an embedded manner.

[0043] The specific details of using the tilling device for wheat planting in the present application to perform tillage operations are as follows:

[0044] First, adjust the position of the vehicle body connecting component 1 on the power equipment and set the distance between the lower side of the transverse frame 12 and the ground.

[0045] After that, start the power equipment to drive the vehicle body connecting component 1 and multiple turning shovel components 2 to move synchronously. During this process, the driving rotating shaft 221 rotates to drive the rocker arm 22 to rotate around the rotating shaft 221, realizing the rocking control of the shovel handle 24. Specifically: the sliding pin I 231 rotates relative to the rocker arm 22, the spherical shaft 15 reciprocates and rotates within the bearing bush 14, and the shovel handle 24 reciprocates and slides within the spherical shaft 15.

[0046] Since the bearing bush 14 is arranged on the transverse frame 12 and is relatively close to the ground, the rocking rotation angle range of the shovel handle 24 is relatively large. With the periodic rocking of the shovel handle 24, the shovel 25 can act on the soil on the surface of the ground in a large range, and the soil shoveling ability is strong; in addition, due to the relatively large rocking rotation angle range of the shovel handle 24, after the shovel 25 shovels up the soil, it can present a state that is generally horizontal as shown in Figure 4 shown. In this way, under the action of the moving inertia of the shovel 25, the soil shoveled up by the shovel 25 can be vertically thrown towards the soil block cutting edge 16. When this part of the soil passes through the soil block cutting edge 16, it is cut by the interception of the soil block cutting edge 16, achieving the purpose of effectively crushing the shoveled soil, which is suitable for the easily compacted soil conditions in the northwest region.

[0047] During the implementation of the above solution, since the shovel 25 acts concentratedly on the shallow soil on the surface of the ground, it will not disrupt the tillage layer, retains the surface root stubble vegetation well, operates in the original ridge, and the original soil layer structure will not be severely damaged, which is beneficial to the growth of crops.

[0048] In order to increase the crushing treatment effect of the soil block cutting edge 16 on the soil, as shown in Figure 3 shown, the multiple soil block cutting edges 16 within the transverse frame 12 are divided into upper and lower layers, and the upper and lower layers of soil block cutting edges 16 are staggered from each other in the horizontal direction. The cross-section of the soil block cutting edge 16 is circular or narrow strip-shaped, and fine steel wires or thin steel bars are used to smoothly carry out effective splitting and crushing treatment on the thrown soil.

[0049] In order to increase the operation stability of the equipment, a gap is provided between the outer side surface of the shovel handle 24 and the inner side surface of the spherical shaft 15 to ensure the smooth sliding of the shovel handle 24 within the spherical shaft 15. A scraping ring 232 is detachably and fixedly installed at the bottom of the sleeve 23, and the inner side surface of the scraping ring 232 abuts against the outer side surface of the shovel handle 24. After the equipment is used for a period of time, the outer side surface of the shovel handle 24 is scraped and cleaned by the scraping ring 232 to ensure the stable operation of the equipment.

[0050] In this embodiment, the rotation of the rocker arms 22 on the multiple turning shovel components 2 at the lower ends of their respective corresponding L-shaped seats 21 uses a high-torque low-speed motor as the power source, transmits the power through the transmission shaft, and then cooperates with the pulley group for synchronous control (not shown in the figure). Parameters such as the diameter of each pulley, the groove specifications of the pulley, and the tension of the belt are adjusted according to the tillage terrain conditions.

[0051] Example Two:

[0052] The features identical to those in Example One will not be elaborated here. The differences between this example and Example One are as follows: As shown in Figure 3 and Figure 6 , in this example, the rotations of the rocker arms 22 on multiple turning shovel components 2 are independently controlled at the lower ends of their respective corresponding L-shaped seats 21. On one side of the support frame Ⅰ212 away from the sleeve 23, a support frame Ⅱ213 is fixedly installed. A rotating drive 214 is installed on the support frame Ⅱ213. The output shaft of the rotating drive 214 is connected to the rotating shaft 221. The parameter model of the rotating drive 214 is adjusted according to the tillage terrain conditions. When the rotating drive 214 is started to drive the rotation of the respective corresponding rotating shafts 221, since the rotations of the multiple rocker arms 22 are independently controlled, the reaction forces when the multiple shovels 25 act on the ground will not be fed back to the whole equipment at the same time, avoiding the problem of loosening at the joints of the equipment components caused by resonance.

[0053] Example Three:

[0054] The features identical to those in Example One will not be elaborated here. The differences between this example and Example One are as follows: As shown in Figure 3 and Figure 4 , in this example, a limiting rim 211 is fixedly installed at the bottom of the L-shaped seat 21, and the rotating shaft 221 passes through the limiting rim 211. Defining the traveling direction of the power equipment as forward, a convex structure is integrally formed on the limiting rim 211 and extends downward and forward of the limiting rim 211. The rocker arm 22 is connected to the sliding pin Ⅰ231 through the pressing arm 26. The sliding pin Ⅰ231 is rotatably connected to the pressing arm 26 and slidably connected to the sliding groove Ⅰ222 on the rocker arm 22. The pressing arm 26 is slidably installed in the middle of the rocker arm 22 and passes through both ends of the rocker arm 22.

[0055] As shown in Figure 6 , Figure 7 and Figure 8 , on both sides of the pressing arm 26, a sliding pin Ⅱ261 and a column 262 are respectively fixedly connected. The sliding pin Ⅱ261 and the column 262 are respectively slidably connected to the fixed ears 224 and the sliding groove Ⅱ223 on both sides of the rocker arm 22. An I-shaped structure is provided at the end of the sliding pin Ⅱ261. The I-shaped structure is fitted with the limiting rim 211 and abuts against the inner side surface of the limiting rim 211. A spring 27 is sleeved outside the column 262. Both ends of the spring 27 are fixedly connected to the fixed ear 224 and the pressing arm 26 respectively.

[0056] Using the limiting edge 211 provided in this embodiment, under the action of the spring 27, the sliding pin II 261 is always in contact with the inner side surface of the limiting edge 211. During the shaking process of the shovel handle 24, the pressing arm 26 drives the sliding pin I 231 to move in the chute I 222, optimizing the movement trajectory of the shovel 25 and enhancing the soil shoveling ability of the shovel 25.

[0057] The virtual movement trajectory of the shovel 25 is as Figure 5 shown. During the shaking process of the shovel handle 24, corresponding points a1, a2 and b1, b2 and c1, c2 are respectively formed at the center and the edge of the shovel 25. When the shovel 25 transitions from point a to point c, under the limiting action of the limiting edge 211, the pressing arm 26 pulls the sliding pin I 231 to move towards the end of the rocker arm 22, causing the shovel handle 24 to move upward by a certain distance at the spherical shaft 15, and the shovel 25 tends to stand up, optimizing the action angle when the shovel 25 shovels the surface soil and enhancing the soil shoveling ability of the shovel 25.

[0058] Embodiment Four:

[0059] The features identical to those in Embodiment One will not be described in detail. The different solution in this embodiment from Embodiment One is as Figure 1 shown. In this embodiment, a feeding component 3 is installed on the towing platform 11. The feeding component 3 includes a feeding tank 31 which stores soil. The feeding tank 31 is fixedly installed in the middle of the end of the towing platform 11, and a plurality of feeding ports 32 are arranged at the bottom of the feeding tank 31, and the feeding ports 32 are located above the soil block cutting edge 16.

[0060] With the operation of the power equipment, under the action of gravity, the soil in the feeding tank 31 falls on the plowed surface after passing through the soil block cutting edge 16, improving the physical properties, biological activity and chemical composition of the soil. In addition, since the soil in the feeding tank 31 is split and dispersed by the soil block cutting edge 16, it can be more evenly spread on the surface, increasing the porosity of the soil, improving the air permeability and water permeability of the soil, and contributing to the healthy growth of crop roots.

[0061] To facilitate the control of the soil feeding process in the feeding tank 31, as Figure 9 shown, a guiding plate 33 is rotatably installed at the lower end of the side of the feeding tank 31, and the upper side surface of the guiding plate 33 can be in contact with the bottom of the feeding tank 31 to block the feeding ports 32, so as to control the soil feeding process in the feeding tank 31.

[0063] The features identical to those in Embodiment One will not be described in detail. The different solution in this embodiment from Embodiment One is as Figure 3As shown, in this embodiment, the shovel 25 is rotatably installed at the lower end of the shovel handle 24, and the relative position between the shovel 25 and the shovel handle 24 is locked by fasteners; the relative angle of the shovel 25 at the bottom of the shovel handle 24 is adjusted to change the initial shoveling angle when the shovel teeth 251 act on the ground, so that the acting force is concentrated at the end or side of the shovel teeth 251 to cope with different hardness of soil conditions.

[0064] Embodiment Six:

[0065] The same features as those in Embodiment One will not be described in detail.

The end of the positioning screw is inserted and connected to one of the plurality of positioning grooves; the relative position of the shovel handle 24 and the sleeve 23 is adjusted to change the limit distance that the shovel 25 can dig down to cope with different depths of tillage requirements.
