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. 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. 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. 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

[0003] In order to solve the deficiencies in the above-mentioned prior art, the purpose of the present invention is to provide a tillage equipment for wheat planting, the rotation center of the shovel body structure of the equipment is close to the ground. With the periodic operation of the shovel body structure, the shovel head position can act on the surface soil in a large range, and has a strong soil shoveling ability. On this basis, the shoveled soil can be effectively crushed, thereby improving the tillage efficiency of the soil that is easily compacted in the northwest region.

[0004] The technical solution adopted by the present invention to solve the technical problem is: Provided is a tillage equipment for wheat planting, comprising a vehicle body connecting component and a plurality of shovel components mounted on the vehicle body connecting component, wherein the vehicle body connecting component comprises a traction platform and a transverse frame, the traction platform is connected to a power device, the shovel components are connected to the traction platform via a reinforcement arm, a plurality of transverse arms and soil cutting edges are fixedly mounted in the transverse frame, and a plurality of bearings are arranged at intervals on the transverse arms.

[0005] The shovel-turning component includes an L-shaped seat, a rocker arm, a sleeve and a shovel handle; the L-shaped seat is detachably fixedly installed on 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, the support frame I is engaged and rotatably connected with the rotating shaft, a sliding pin I is fixedly installed on the side of the sleeve, the sliding pin I is rotatably 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, the shovel handle passes through the spherical shaft and is slidably connected with the spherical shaft, and the spherical shaft is engaged and rotatably installed in the bearing shell.

[0006] In the present application, an optional technical solution for the rotation control method of the rocker arm is: the rocker arms on multiple shovel components rotate at the lower ends of their corresponding L-shaped seats, using a large-torque low-speed motor as a power source, transmitting power through a drive shaft, and then cooperating with a pulley group for synchronous control. Parameters such as the diameter of each pulley, wheel groove specifications, and belt tension are adjusted according to the tilling terrain conditions.

[0007] In the present application, another optional technical solution for the rotation control method of the rocker arm is: the rotation of the rocker arms on multiple shoveling components at the lower ends of their corresponding L-shaped seats is independently controlled from each other; a support frame II is fixedly installed on the side of the support frame I away from the sleeve, and a rotation driver is installed on the support frame II, and the output shaft of the rotation driver is connected to the rotating shaft, and the parameter model of the rotation driver is adjusted according to the tillage terrain conditions.

[0008] Furthermore, a limiting edge is fixedly installed on the bottom of the L-shaped seat, and the rotating shaft passes through the limiting edge; the moving direction of the power equipment is defined as forward, and a protruding structure is integrally formed on the limiting edge, and the protruding structure extends to the front and lower part of the limiting edge; the rocker arm is connected to the sliding pin I through the tightening arm, the sliding pin I is rotatably connected to the tightening arm and is slidably connected to the sliding groove I on the rocker arm, and the tightening arm is slidably installed in the middle of the rocker arm and passes through both ends of the rocker arm.

[0009] The two sides of the clamping arm are respectively fixedly connected with a sliding pin II and a column, which 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 provided at the end of the sliding pin II, which is embedded in the limiting edge and is tightened against the inner side surface of the limiting edge. A spring is sleeved on the outer side of the column, and the two ends of the spring are respectively fixedly connected with the fixing ear and the clamping arm.

[0010] Furthermore, a delivery component is installed on the traction platform, and the delivery component includes a delivery tank, which is fixedly installed on the middle side of the end of the traction platform. A plurality of delivery ports are arranged at the bottom of the delivery tank, and the delivery ports are located above the cut edges of the soil blocks.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. In the wheat planting tillage equipment exemplified by the present invention, the bearing is arranged on the transverse frame, which is relatively close to the ground, and the shovel handle has a large swing angle range. With the periodic swing of the shovel handle, the shovel can act on the surface soil in a large range, and has a strong shoveling ability. In addition, since the shovel handle has a large swing angle range, the shovel can present an overall horizontal state as shown in the figure after shoveling the soil. In this way, under the action of the shovel's moving inertia, the soil shoveled by the shovel can be thrown vertically toward the cut edge of the soil block. When this part of the soil passes through the cut edge of the soil block, it is cut by the interception action of the cut edge of the soil block, thereby achieving the purpose of effectively crushing the shoveled soil. The equipment is suitable for soil conditions that are prone to compaction in the northwest region.

[0012] 2. In the tillage equipment for wheat planting in the example of the present invention, a limiting edge is fixedly installed at the bottom of the L-shaped seat, and a protruding structure is integrally formed on the limiting edge; during the shaking process of the shovel handle, corresponding points a, a and b, b and c, and c are formed at the center and edge of the shovel respectively; when the shovel transitions from point a to point c, under the limiting action of the limiting edge, the tightening arm pulls the sliding pin I toward the direction close to the end of the rocker arm, so that the shovel handle moves an end distance upward at the spherical axis, and the shovel tends to stand upright, thereby optimizing the angle of action of the shovel when shoveling the surface soil and enhancing the shovel's shoveling ability.

[0013] 3. The wheat planting tillage equipment exemplified in the present invention, with the operation of the power equipment, under the action of gravity, the soil in the delivery tank falls on the tilled surface after being cut by the soil blocks, thereby improving the physical properties, biological activity and chemical composition of the soil. In addition, since the soil in the delivery tank is broken and dispersed by the cut edges of the soil blocks, it can be spread more evenly 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 the crop root system.

[0014] 4. The wheat planting tillage equipment of the example of the present invention starts the rotary drive to drive the corresponding rotating shafts to rotate. Since the rotation controls of the multiple rocker arms are independent of each other, the reaction forces of the multiple shovels acting on the ground will not be fed back to the entire equipment at the same time, thereby avoiding the problem of loose connections between equipment components due to resonance.

[0015] 5. In the wheat planting tillage equipment exemplified in the present invention, the shovel acts on the shallow soil of the surface, does not disturb the tillage layer, better preserves the surface stubble vegetation, operates on the original ridge, and the original soil layer structure will not be seriously damaged, which is beneficial to crop growth.

DETAILED DESCRIPTION

[0018] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. It should also be noted that, for ease of description, only the parts related to the invention are shown in the drawings.

[0024] Embodiment 1: like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a tillage equipment for wheat planting, including a vehicle body connecting component 1, and a plurality of 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, the shovel components 2 are connected to the traction platform 11 through a reinforcement arm 17, a plurality of transverse arms 13 and soil cutting edges 16 are fixedly installed in the transverse frame 12, and a plurality of bearings 14 are arranged on the transverse arms 13.

[0025] Among them, the power equipment can be selected from agricultural tractors of models such as John Deere agricultural machinery tractors, Dongfanghong tractors, Zoomlion heavy machinery tractors, wheeled tractors, crawler tractors and walk-behind tractors, and the specific selection is based on the number of shovel parts 2 and the cultivated area at the same time.

[0026] like Figure 3 As 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 accommodate. A plurality of shovel teeth 251 are provided at the end of the shovel 25 .

[0027] like Figure 4 and Figure 6 As shown, the 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 mounted on the bottom of the reinforcement arm 17, a support frame Ⅰ212 is fixedly mounted on the side of the L-shaped seat 21, a rotating shaft 221 is fixedly mounted on the rocker arm 22, the support frame Ⅰ212 is engaged and rotatably connected with the rotating shaft 221, a sliding pin Ⅰ231 is fixedly mounted on the side of the sleeve 23, the sliding pin Ⅰ231 is rotatably connected with the rocker arm 22, the shovel handle 24 is installed in 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 engaged and rotatably mounted in the bearing bush 14.

[0028] The specific details of using the wheat planting tillage equipment of this application to implement arable land operations are as follows: First, the position of the vehicle body connecting component 1 on the power equipment is adjusted to set the distance between the lower side of the transverse frame 12 and the ground.

[0029] Afterwards, the power equipment is started to drive the vehicle body connecting component 1 and multiple shovel components 2 to move synchronously. During this process, the driving shaft 221 rotates, driving the rocker arm 22 to rotate around the shaft 221, thereby realizing the shaking control of the shovel handle 24. Specifically: the sliding pin Ⅰ231 rotates relative to the rocker arm 22, the spherical shaft 15 reciprocates in the bearing 14, and the shovel handle 24 slides back and forth in the spherical shaft 15.

[0030] Since the bearing bush 14 is arranged on the transverse frame 12 and is relatively close to the ground, the shovel handle 24 has a large swing angle range. With the periodic swing of the shovel handle 24, the shovel 25 can act on the soil on the surface in a large range, and has a strong shoveling ability. In addition, since the shovel handle 24 has a large swing angle range, the shovel 25 can present the following after shoveling the soil. Figure 4 The overall state shown is tending to be horizontal. In this way, under the action of the moving inertia of the shovel 25, the soil shoveled by the shovel 25 can be thrown vertically to 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 effect of the soil block cutting edge 16, thereby achieving the purpose of effectively crushing the shoveled soil. It is suitable for the soil conditions that are easy to compact in the northwest region.

[0031] In the process of implementing the above scheme, since the shovel 25 acts on the shallow soil of the surface, the tillage layer will not be disturbed, the surface root stubble vegetation will be better preserved, the original ridge operation will not be seriously damaged, and the original soil layer structure will not be seriously damaged, which is beneficial to the growth of crops.

[0032] In order to increase the crushing effect of the soil block cutting edge 16 on the soil, Figure 3 As shown, the multiple soil cutting edges 16 in the transverse frame 12 are divided into two layers, and the soil cutting edges 16 of the upper and lower layers are staggered in the horizontal direction. The cross-section of the soil cutting edges 16 is circular or narrow strip-shaped, and thin steel wires or thin steel bars are used to effectively cut and crush the thrown soil smoothly.

[0033] In order to increase the operating 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 in the spherical shaft 15, and a scraper ring 232 is detachably fixedly installed at the bottom of the sleeve 23, and the inner side surface of the scraper ring 232 abuts against the outer side surface of the shovel handle 24. After the equipment has been used for a period of time, the scraper ring 232 is used to scrape and clean the outer side surface of the shovel handle 24 to ensure stable operation of the equipment.

[0034] In this embodiment, the rocker arms 22 on the multiple shoveling components 2 rotate at the lower ends of their respective L-shaped seats 21, and a high-torque low-speed motor is used as a power source to transmit power through a drive 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 wheel groove specifications, and the tension of the belt are adjusted according to the tilling terrain conditions.

[0035] Embodiment 2: The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Figure 3 and Figure 6 As shown, in this embodiment, the rotation of the rocker arms 22 on the multiple shovel components 2 at the lower ends of their respective L-shaped seats 21 is independently controlled; a support frame II 213 is fixedly installed on the side of the support frame I 212 away from the sleeve 23, and a rotation driver 214 is installed on the support frame II 213. The output shaft of the rotation driver 214 is connected to the rotating shaft 221, and the parameter model of the rotation driver 214 is adjusted according to the tillage terrain conditions; the rotation driver 214 is started to drive the corresponding rotating shafts 221 to rotate. Since the rotation control of the multiple rocker arms 22 is independent of each other, the reaction force of the multiple shovels 25 when acting on the ground will not be fed back to the equipment as a whole at the same time, thereby avoiding the problem of loose connections between equipment components caused by resonance.

[0036] Embodiment three: The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Figure 3 and Figure 4 As shown, in this embodiment, the bottom of the L-shaped seat 21 is fixedly installed with a limiting edge 211, and the rotating shaft 221 passes through the limiting edge 211; the moving direction of the power equipment is defined as forward, and a protruding structure is integrally formed on the limiting edge 211, and the protruding structure extends to the front and lower part of the limiting edge 211; the rocker arm 22 is connected to the sliding pin Ⅰ231 through the tightening arm 26, and the sliding pin Ⅰ231 is rotatably connected to the tightening arm 26 and is slidably connected to the sliding groove Ⅰ222 on the rocker arm 22, and the tightening arm 26 is slidably installed in the middle of the rocker arm 22 and passes through both ends of the rocker arm 22.

[0037] like Figure 6 , Figure 7 and Figure 8 As shown, the two sides of the clamping arm 26 are respectively fixedly connected with a sliding pin II 261 and a column 262, which are respectively slidably connected with the fixed ears 224 and the slide grooves II 223 on both sides of the rocker arm 22. The end of the sliding pin II 261 is provided with an I-shaped structure, which is embedded in the limiting edge 211 and is tightened against the inner side surface of the limiting edge 211. The outer side of the column 262 is provided with a spring 27, and the two ends of the spring 27 are respectively fixedly connected with the fixing ears 224 and the clamping arm 26.

[0038] By using the position-limiting edge 211 provided in this embodiment, under the action of the spring 27, the sliding pin II 261 always contacts the inner side surface of the position-limiting edge 211. When the shovel handle 24 is shaken, the pressing arm 26 drives the sliding pin I 231 to move in the slide groove I 222, thereby optimizing the moving track of the shovel 25 and enhancing the shoveling ability of the shovel 25. The virtual moving track of the shovel 25 is as follows: Figure 5 As shown, during the shaking process of the shovel handle 24, corresponding points a1, a2, b1, b2, c1 and c2 are formed at the center and edge of the shovel 25 respectively; when the shovel 25 transitions from point a to point c, under the limiting action of the limiting edge 211, the tightening arm 26 pulls the sliding pin Ⅰ231 to move toward the end of the rocker arm 22, so that the shovel handle 24 moves an end distance upward at the spherical shaft 15, and the shovel 25 tends to stand upright, thereby optimizing the angle of action of the shovel 25 when shoveling the surface soil and enhancing the shovel 25's shoveling ability.

[0039] Embodiment 4: The features of this embodiment that are the same as those of the first embodiment are not described in detail.

[0040] As the power equipment runs, under the action of gravity, the soil in the delivery tank 31 passes through the soil block cutting edges 16 and falls onto the plowed surface, thereby improving the physical properties, biological activity and chemical composition of the soil. In addition, since the soil in the delivery tank 31 is more evenly spread on the surface after being cut and dispersed by the soil block cutting edges 16, the porosity of the soil is increased, and the air permeability and water permeability of the soil are improved, which is conducive to the healthy growth of crop roots.

[0041] In order to facilitate the control of the soil delivery process in the delivery tank 31, Fig. 9 As shown, a guide plate 33 is rotatably installed at the lower end of the side of the delivery tank 31, and the upper side of the guide plate 33 can abut against the bottom of the delivery tank 31 to block the delivery port 32, so as to control the delivery process of the soil in the delivery tank 31.

[0042] Embodiment five: The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Figure 3As shown, in this embodiment, the shovel 25 is rotatably mounted on the lower end of the shovel handle 24, and the relative position between the shovel 25 and the shovel handle 24 is locked by a fastener; 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 force is concentrated on the end or side of the shovel teeth 251 to cope with soil conditions of different hardness.

[0043] Embodiment six: The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Figure 4 As shown, in this embodiment, the shovel handle 24 and the sleeve 23 are adjustably fixedly connected, a positioning screw is rotatably installed on the sleeve 23, and a plurality of positioning grooves are evenly spaced at the upper end of the side of the shovel handle 24, and the end of the positioning screw is plugged into one of the plurality of positioning grooves; the relative position of the shovel handle 24 and the sleeve 23 is adjusted to change the maximum distance that the shovel 25 can dig, so as to meet the requirements of tilling at different depths.

Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept.
