Description

Technical Field

[0001] This utility model relates to an agricultural machinery soil turning device. Background Technology

[0002] In agricultural production, soil tillage is a crucial step. Tillage loosens the soil, improves its structure, removes weeds, and prepares the soil for sowing. Traditional tillage devices mostly use tractor-drawn rotary tillers, which are directly connected to the tractor via a suspension frame and powered by the tractor's power take-off shaft.

[0003] However, existing devices of this type have some obvious drawbacks: First, the connection method with insufficient rigidity or cushioning will directly transmit huge impact forces to the tractor and the tilling device itself when encountering hard obstacles, which not only affects the comfort of operation, but also makes it more likely to cause premature damage to the key components of the equipment.

[0004] Based on the above problems, we designed an agricultural machinery soil turning device that can buffer when there is a large impact force. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an agricultural machinery soil turning device that can buffer when there is a large impact force.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] An agricultural machinery soil-turning device, comprising:

[0008] A buffer connection device is used to connect the traction machinery.

[0009] A frame is fixedly installed via the buffer connection device. The frame has an installation port. A bracket plate is fixedly installed at the end of the frame away from the installation port. A wheel is installed via the bracket plate and the frame.

[0010] A rotating shaft is rotatably mounted inside an installation opening. A rotating roller is fixed on the rotating shaft, and multiple soil-turning hooks are installed on the outer wall of the rotating roller. When the wheel acts on the ground surface, the soil-turning hooks are driven into the soil by the rotating roller.

[0011] A drive device is provided, which is connected to the bracket plate device, and a transmission unit is provided between the drive device and the rotating shaft.

[0012] Preferably, the buffer connection device includes a sleeve, a connecting bracket, and a connecting plate. The sleeve is fixed at the middle position on the side of the frame away from the mounting opening. The sleeve has an inner hole, and a cover plate is detachably installed at the opening of the sleeve. A through hole is provided at the center of the cover plate, and a guide block is provided on the wall of the through hole. The connecting bracket is L-shaped, and a guide rod is provided on the end face of the connecting bracket facing the cover plate. A guide groove is axially passed through the outer wall of the guide rod. The guide rod passes through the through hole and is inserted into the sleeve. A limit ring is fitted at the end of the guide rod inserted into the sleeve. A spring is fitted onto the guide rod, and the spring acts between the cover plate and the limiting ring. The guide groove cooperates with the guide block. A first rotating seat is provided at the end of the connecting bracket away from the guide rod, and a second rotating seat is provided at the top of the connecting bracket near the frame. The connecting plate is used to connect the traction mechanism, and a connecting arm is provided at the end of the connecting plate away from the traction mechanism. A pin is fitted between the connecting arm and the first rotating seat. A third rotating seat is provided at the top of the end of the connecting plate away from the traction mechanism, and a telescopic rod is fitted between the second rotating seat and the third rotating seat.

[0013] Preferably, a safety bolt is fitted between the rotating shaft and the rotating roller.

[0014] Preferably, the soil-turning hook includes a hook rod, and the end of the hook rod is provided with a hook claw, the tip of the hook claw facing the same direction as the rotation direction of the soil-turning hook.

[0015] Preferably, the driving device is a drive motor.

[0016] Preferably, the transmission unit is a belt transmission unit, and the transmission belt used is a synchronous toothed belt.

[0017] Preferably, a cover is fixed to the top of the frame, and the side of the cover away from the connecting device has an opening through which soil turned up by the soil-turning hook is thrown out.

[0018] The beneficial effects of this utility model are:

[0019] One advantage is that the buffer connection device, especially the buffer mechanism composed of guide rods, springs, guide blocks, and limit rings, effectively absorbs and attenuates the impact and vibration generated when the traction machinery travels on uneven fields. This greatly reduces structural damage to the traction machinery and the tilling device itself, and improves the service life and operational stability of the equipment.

[0020] Secondly, the shaft and roller are connected by safety bolts, forming a simple mechanical overload protection system. When the turning hook accidentally hits an insurmountable obstacle, the safety bolts will be sheared first, disengaging the roller from the drive power. This effectively prevents the drive unit from burning out or the transmission components from being damaged, protecting the core power unit and reducing maintenance costs and downtime.

[0021] Thirdly, the telescopic rod connecting the second and third rotating seats allows for convenient adjustment of the pitch angle of the entire tillage device relative to the traction machinery. This enables the operator to quickly adjust the entry angle of the tillage hook according to different soil conditions and tillage depth requirements, optimizing operational efficiency and enhancing the adaptability and convenience of the equipment.

[0022] Fourthly, the cover installed on top of the frame effectively blocks and guides the soil turned up by the soil-turning hook, causing it to be thrown out from a specific opening, thus avoiding disorderly splashing of soil. This not only creates a safer operating environment and protects the operators, but also makes the work area cleaner. Attached Figure Description

[0038] The drive device 4 is connected to the bracket plate 22, and a transmission unit 41 is connected between the drive device 4 and the rotating shaft 3.

[0039] See Figure 1 , Figure 2 and Figure 3 As shown, the buffer connection device 1 includes a sleeve 11, a connecting bracket 12, and a connecting plate 13. The sleeve 11 is welded and fixed to the middle position of the side of the frame 2 away from the mounting opening 21. The sleeve 11 has an inner hole, and a cover plate 14 is detachably installed at the opening of the sleeve 11. A through hole 15 is provided at the center of the cover plate 14. The diameter of the through hole 15 is smaller than the diameter of the inner hole of the sleeve 11. A guide block 150 is provided on the wall of the through hole 15. The connecting bracket 12 is L-shaped. A guide rod 120 is provided on the end face of the connecting bracket 12 facing the cover plate 14.
