Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, in particular to a micro-tillage machine which is easy to assemble and disassemble. Background Art

[0002] With the rapid development of agricultural mechanization, micro-tillage machines have been widely used in farmland operations such as soil tillage and land preparation, especially in small-scale agriculture and fruit and vegetable planting. However, traditional micro-tillage machines often face the following problems during operation: on the one hand, frequent operations will cause damage to some parts, especially rotary tillage cutters and transmission systems; on the other hand, the process of repairing and replacing parts of traditional micro-tillage machines is cumbersome, especially when working in the soil, due to the high viscosity and rough environment of the soil, the mechanical equipment is damaged and maintenance is difficult. Therefore, how to design a micro-tillage machine that is easy to disassemble and reduce the damage of parts during operation has become the key to solving this problem;

[0003] Although the micro-tillage machines in the prior art have certain disassembly functions, most designs fail to effectively balance the ease of operation and the convenience of repair. Traditional designs often require a relatively complicated disassembly and assembly process, which increases the maintenance time. In addition, the traditional micro-tillage machines lack effective protective devices. Once obstacles such as stones are encountered during work, the tool or transmission system may be damaged, which may even affect the working performance of the entire machine. In order to improve work efficiency and reduce downtime, there is an urgent need for a micro-tillage machine that can quickly disassemble and replace damaged parts and has good protection capabilities;

[0004] Under this background, designing a micro-tillage machine that is easy to disassemble and assemble has become an urgent problem to be solved. The existing Chinese patent with publication number: CN116530240B discloses a detachable micro-tillage machine. The clamping operation of the reset spring of this device can realize quick disassembly and assembly. However, in actual application, it is easy to have loose fixation and high probability of damage between the fixing parts, which cannot effectively reduce the preparation time during operation.

[0005] Therefore, it is necessary to design a micro-tillage machine that is easy to disassemble and assemble and can reduce damage and maintenance time during tillage operations. Summary of the invention

[0018] By designing an automatic adjustment function of the rotation resistance, the mounting ring, the fixing shell, and the first magnet are connected to the connecting ring through a torsion spring structure. When the speed of the crushing plate slows down due to an obstacle, the first magnet approaches the second magnet due to inertia and adsorbs the second magnet, so that the second magnet triggers the pressure switch, thereby triggering the control module to perform adjustments, so that the pneumatic telescopic rod supports the device to cross the obstacle, avoiding the risk of equipment damage caused by high loads during the working process due to stones, and ensuring the stability and long-term durability of the equipment operation;

[0019] By providing a gravity-controlled airflow regulating device, the design of the mass difference between the counterweight ball and the baffle ensures that the airflow is always concentrated on the soil crushing site.

An air supply machine 207 is also fixedly connected to the outside of the frame 1, and an air pipe 208 is fixedly connected to the output end of the air supply machine 207. A threaded hole that passes through the upper and lower parts is opened at the overlap of the connecting rod 7 and the first fixing tube 8. A threaded connection tube 209 is inserted into the threaded hole at the overlap of the connecting rod 7 and the first fixing tube 8. The upper end of the threaded connection tube 209 is fixedly connected to the connecting rod 7 and the first fixing tube 8 through a nut. The interior of the threaded connection tube 209 is a hollow structure. An exhaust eye 210 is fixedly connected to the side wall of the threaded connection tube 209. The upper end of the threaded connection tube 209 is fixedly connected to one end of the air pipe 208. The connecting rod 7 is a hollow structure.The interior of the first fixed cylinder 8 is connected to the output end of the air supply machine 207 through the connecting rod 7, the threaded connecting cylinder 209, and the air pipe 208. The left and right sides of the ball shaft 6 are fixedly connected with the connecting rod 7. The first fixed cylinder 8 is arranged on the two connecting rods 7. The second fixed cylinder 9 is arranged on the two first fixed cylinders 8. The fixing ring 201, the crushing plate 202, the connecting ring 203, the airway 204, the air hole 205, and the guide mechanism 206 are arranged in six groups, of which four groups are arranged on the first fixed cylinder 8, and two groups are arranged on the second fixed cylinder 9. The first fixed cylinder 8 and the second fixed cylinder 9 form a sealed tubular structure inside;

[0038] The hand throttle and gear controller are arranged on the handrail 4 to control the power output of the power output device 3 and the differential device 2, and then control the rotation speed of the transmission rod 5, so that the transmission rod 5 drives the ball shaft 6 and the connecting rod 7 to rotate, so that the rate at which the crushing plate 202 crushes the ground can be controlled;

[0039] During operation, the power output device 3 drives the output end of the differential device 2 to rotate the transmission rod 5 through transmission, and the lower end of the transmission rod 5 drives the ball shaft 6 and the connecting rod 7 to rotate through the bevel gear group, thereby rotating the first fixed cylinder 8, the second fixed cylinder 9, the side plate 10 and the structure on the surface thereof. While the first fixed cylinder 8 and the second fixed cylinder 9 rotate, the connecting ring 203, the fixed ring 201 and the upper side of the crushing plate 202 rotate synchronously from back to front, and the crushing plate 202 crushes the ground while driving the device forward, and the side plate 10 is conducive to maintaining the direction of travel during the movement;

[0040] Since the differential device 2 and the power output device 3 of the device are higher than the ground and are less affected by the working environment, the transmission rod 5 is connected to the ball shaft 6 through the bevel gear set to drive the rotation of the ball shaft 6, and the ball shaft 6 is rotatably connected to the inner wall of the frame 1 through the bearing, and the connection between the first fixed cylinder 8 and the connecting rod 7 is relatively fixed by a detachable threaded connection cylinder 209, and the connection between the first fixed cylinder 8 and the second fixed cylinder 9 and the second fixed cylinder 9 and the side plate 10 are fixed by bolts. Therefore, when a certain crushing plate 202 or the first fixed cylinder 8, the second fixed cylinder 9 and the surface structure thereof are damaged, they can be quickly disassembled and replaced by removing the bolts, which reduces the disassembly and maintenance time;

[0041] During operation, the air supply machine 207 continuously inputs compressed gas into the sealed cavity formed between the first fixed cylinder 8 and the second fixed cylinder 9 through the air pipe 208 and the threaded connection cylinder 209. The gas enters the interior of the air passage 204 through the air hole 205 and is then ejected from the far end of the crushing plate 202. When the far end of the crushing plate 202 crushes the ground, the compressed air flow is quickly discharged from the gap between the crushing plate 202 and the soil while being inserted into the ground, which can accelerate the drying speed of the surface of the crushing plate 202, thereby reducing soil adhesion, thereby reducing rotational resistance, and reducing the load required for crushing the soil, thereby reducing the possibility of damage. In addition, the compressed air flow helps to form air pockets inside the soil turned up on the ground to increase the soil bulkiness.

[0042] For example 2, please refer to Figure 1-11 The present invention provides a technical solution: a support mechanism 11 includes a support arm 101, one end of the support arm 101 is fixedly connected to the outer wall of the frame 1, the other end of the support arm 101 is hinged with a plow bar 102, a pneumatic telescopic rod 103 is hinged to the middle of the outer wall of the support arm 101, and the lower end of the pneumatic telescopic rod 103 is hinged to the middle of the outer wall of the plow bar 102. The support mechanism 11 also includes a mounting ring 104, the outer wall of the mounting ring 104 is connected to the outer wall of the connecting ring 203 through a torsion spring, the mounting ring 104 is located on the connecting ring 203 on one side of the principle fixing ring 201, the outer wall of the mounting ring 104 is fixedly connected to a fixing shell 105, the inner wall of the fixing shell 105 is fixedly connected to a first magnet 106, and the connecting ring 20 3 is fixedly connected to a fixing frame 107 on the outer wall thereof, a spring 108 is fixedly connected to the rear side of the fixing frame 107, a second magnet 109 is fixedly connected to the rear end of the spring 108, the other end of the second magnet 109 extends to the inside of the fixing frame 107, the second magnet 109 is a U-shaped structure, and a pressure switch 110 is fixedly connected to the inner wall of the fixing frame 107 at the middle part of the second magnet 109, the first magnet 106 can move relative to the fixing frame 107, and when the fixing shell 105 contacts the fixing frame 107, the suction force of the first magnet 106 on the second magnet 109 is greater than the force required for the deformation of the spring 108, and the fixing frame 107 is located at the rear side of the fixing shell 105 and on the deflection path of the fixing shell 105;

[0043] When the crushing plate 202 rotates continuously to crush the soil, the lower end of the plow rod 102 is located inside the soil to provide a stabilizing effect for the device. If the crushing plate 202 contacts stones inside the soil during its movement, the movement of the crushing plate 202 will be instantly blocked, and the rotation speed of the crushing plate 202 and the connecting ring 203 will be instantly slowed down, causing the mounting ring 104 and the fixed shell 105 and the first magnet 106 on its surface to deflect toward the fixed frame 107 due to inertia, causing the torsion spring at the connection between the mounting ring 104 and the connecting ring 203 to deform and store energy. When the first magnet 106 approaches the fixed frame 107, the second magnet 109 will move toward the fixed shell 105 due to the suction force of the first magnet 106, causing the spring 108 to contract and store energy. At the same time, the other side of the second magnet 109 will squeeze the pressure switch 110. The switch 110 is electrically connected to the control module of the device, and the pneumatic telescopic rod 103 is electrically connected to the control module of the device. When the pressure switch 110 is triggered, the pneumatic telescopic rod 103 will perform a rapid telescopic action. At the same time, the fixed shell 105 and the mounting ring 104 rotate and reset due to the torsion spring rebound effect at the connection between the mounting ring 104 and the connecting ring 203. At this time, since the lower end of the plow rod 102 is located inside the soil, the lower end of the plow rod 102 will support the device to move forward and upward, so that the crushing plate 202 can pass over the stone position due to the support of the plow rod 102, thereby avoiding damage to the crushing plate 202 caused by excessive impact force after the crushing plate 202 contacts the stone, and avoiding damage to the power output component of the device after the crushing plate 202 is blocked by the stone, thereby reducing the possibility of damage to the device;

[0044] For example 3, please refer to Figure 1-13 The present invention provides a technical solution: the flow guide mechanism 206 includes a follower ring 601, the outer wall of the follower ring 601 is fixedly connected to the inner wall of the first fixed cylinder 8, the inner wall of the follower ring 601 is fixedly connected to a bracket 602, one side of the bracket 602 is rotatably connected to a swivel 603 through a bearing, the upper side of the swivel 603 is fixedly connected to a baffle 605, the lower side of the swivel 603 is fixedly connected to a weight ball 604, four air holes 205 are opened on the inner side of the fixed ring 201 on the first fixed cylinder 8, the positions of the four air holes 205 correspond to the positions of the four crushing plates 202, the mass of the weight ball 604 is greater than the mass of the baffle 605, and the baffle 605 blocks the three air holes 205 on the upper side;

[0045] When the first fixed cylinder 8 drives the crushing plate 202 to rotate and crush the soil, since the mass of the weight ball 604 is greater than the mass of the baffle plate 605, and the rotating ring 603 is connected to the bracket 602 through the bearing, although the follower ring 601 and the bracket 602 rotate synchronously with the first fixed cylinder 8, the weight ball 604 is always located at the lower side due to gravity, and the baffle plate 605 always covers the three air holes 205 located at the upper side, so that the airflow is more concentrated and ejected from the far end of the crushing plate 202 located at the lower side, making the airflow effect more obvious;

[0046] When the crushing plate 202 is blocked by stones and the plow bar 102 supports the device to move forward, the weight ball 604 will lag behind the movement of the follower ring 601 due to inertia, and the weight ball 604 will drive the baffle 605 to deflect, so that the baffle 605 deflects forward, and the air hole 205 located on the rear side is exposed to the outside of the baffle 605. At the same time, since the first fixed cylinder 8 and the crushing plate 202 are continuously in a rotating state at this time, the crushing plate 202 originally blocked by the stone has moved to the first On the rear side of the fixed cylinder 8, when the crushing plate 202 is blocked and passes over stones, the air flow is always ejected from the far end of the same crushing plate 202, so that when the middle section of the crushing plate 202 is blocked and the breaking ability of the far end of the crushing plate 202 to the soil decreases, the compressed air flow can assist in breaking the soil, thereby reducing the probability of breakage caused by the resistance exerted by the soil on the far end after the crushing plate 202 is blocked by stones, and the air flow accelerates the heat dissipation on the surface of the crushing plate 202, so that the friction heat of the crushing plate 202 during operation can be dissipated faster, thereby increasing its wear resistance and hardness.
