Description

Technical Field

[0001] The present invention belongs to the technical field of sandy land greening, and specifically refers to a vegetation planting device for sandy deserts and gobi. Background Art

[0002] At present, there is a large area of desertified land in China that needs to be treated, and the surface conditions of these lands vary greatly due to different regions. The main types include deserts, gobi gravels, and deserts with a small amount of vegetation. These landforms also have characteristics such as large slope changes, large differences in surface hardness, and huge working areas. When considering planting new plants, it is necessary to minimize damage to the original vegetation. Therefore, the planting device should not only consider having a certain width to improve work efficiency, but also consider whether the width of the device can avoid damaging the original plants.

[0003] Most of the existing planting devices are used for construction in good farmland operation environments. The land is generally soft soil that has been treated by a rotary tiller, and the slope is basically not considered, making it difficult to be applicable to sandy desert and gobi planting. In addition, in order to quickly obtain nutrients for barren land, water-soluble organic fertilizers are required for operation. There is no professional liquid organic fertilizer construction equipment for sandy deserts and gobi in the prior art, and usually spraying equipment is used instead. Secondly, there is no integrated equipment for simultaneous operation of no-till seeding and liquid fertilizer. More prominent is the contradiction that traditional automatic seeders are used in farmland environments, and their structures are not suitable for geological conditions such as gravel gobi, deserts, and degraded grasslands. Summary of the Invention

[0004] To solve the above existing problems, the present invention provides a vegetation planting device for sandy deserts and gobi with high practicability, a secondary beam hanging frame type tillage and seeding mechanism, which is convenient for realizing the integrated setting of simultaneous operation of no-till seeding and liquid fertilizer, and convenient for controlling the forward trajectory of the device.

[0005] The technical solution adopted by the present invention is as follows: The vegetation planting equipment for sandy deserts and gobi of the present invention includes a vehicle body main beam, a dynamic auxiliary beam, a dynamic adjustable tillage and seeding device, a driving and traveling mechanism, a fertilizer supply device, and a rear-wheel steering device. The driving and traveling mechanism and the rear-wheel steering device are symmetrically arranged at both ends of the vehicle body main beam. The dynamic auxiliary beam is hinged on the driving and traveling mechanism and the vehicle body main beam. The fertilizer supply device is arranged on the upper wall of the vehicle body main beam. The dynamic adjustable tillage and seeding device is arranged on the vehicle body main beam and the dynamic auxiliary beam. The driving and traveling mechanism includes an engine, a driving wheel, a driving shaft, a driving sprocket, a driven sprocket, and a driving chain. The driving shaft is rotatably arranged on the vehicle body main beam. The driving wheel is arranged on the driving shaft. The vehicle body main beam bears the weight of all the equipment on the vehicle. An engine fixing frame is arranged on the vehicle body main beam, and the engine fixing frame is arranged directly above the driving wheel. The engine is arranged on the engine fixing frame. The driving sprocket is arranged on the output shaft of the engine. The driven sprocket is arranged on the driving shaft. The driving chain is wound around the driving sprocket and the driven sprocket. The outer walls of the driving sprocket and the driven sprocket are provided with teeth. The driving chain meshes with the driving sprocket and the driven sprocket respectively. The engine drives the driving shaft to rotate through the driven sprocket, the driving sprocket, and the driving chain, thereby driving the driving wheel to rotate and providing power for the vehicle to travel.The described dynamic adjustment tillage and seeding device includes an automatic seeding box, a speed-changing gear, a manual clutch, a seeding sprocket and chain mechanism, a seeding conduit, a seeding plow blade and a main plow blade. The automatic seeding box is arranged at one end of the vehicle body main beam close to the rear-wheel steering device. One end of the dynamic auxiliary beam is arranged in the middle of the vehicle body main beam, and the other end of the dynamic auxiliary beam is provided with a hinge plate which is rotatably arranged on the drive shaft. The dynamic auxiliary beam is hinged to the drive shaft through the hinge plate. When the driving wheel rotates, the dynamic auxiliary beam only moves forward with the vehicle and does not rotate with the drive shaft. The seeding plow blade and the main plow blade are arranged on the dynamic auxiliary beam. The seeding plow blade is arranged at one end of the dynamic auxiliary beam close to the rear-wheel steering device, and the main plow blade is arranged at one end of the dynamic auxiliary beam close to the driving wheel. The automatic seeding box is arranged at one end of the vehicle body main beam close to the rear-wheel steering device. A seed storage box is communicated and arranged at the upper end of the automatic seeding box, and the seed storage box is convenient for storing seeds. The automatic seeding box adopts an existing general automatic seeding box. The speed-changing gear is rotatably arranged above the vehicle body main beam, and the manual clutch is arranged on the side wall of the vehicle body main beam. The power shaft of the automatic seeding box is connected to the drive shaft through the seeding sprocket and chain mechanism and the speed-changing gear. The seeding sprocket and chain mechanism is connected to the manual clutch. The drive shaft drives the power shaft of the automatic seeding box to rotate through the speed-changing gear and the seeding sprocket and chain mechanism, so as to drive the automatic seeding box to work for seeding. The speed-changing gear is convenient for adjusting the rotation speed of the power shaft of the automatic seeding box so as to adjust the seeding speed. After the speed-changing gear is set, the required rotation speed of the power shaft of the automatic seeding box can be obtained. When the vehicle is in transit, the manual clutch disconnects the power shaft of the automatic seeding box from the driving wheel to stop seeding. The seeding plow blade is provided with a seeding through hole, and the seeding conduit is communicated and arranged between the output end of the automatic seeding box and the seeding through hole. The seeds sown by the automatic seeding box are conveyed to the seeding through hole of the lower seeding plow blade through the seeding conduit for seeding. When the vehicle moves forward, the main plow blade drives the sand to be plowed, and the seeding plow blade sows the sand. The number of rows to be sown by the vehicle is determined by the number of the main plow blade and the seeding plow blade and corresponds to the number of automatic seeding boxes.;

[0006] Further, the fertilizer supply device includes a fertilizer water tank, a gear pump, a drive chain, a fertilizer supply sprocket, a fertilizer supply drive sprocket, and a fertilizer spreading pipe. The fertilizer water tank is arranged in the middle of the upper wall of the main body beam of the vehicle body. The gear pump is arranged on the main body beam of the vehicle body on one side of the fertilizer water tank. The fertilizer supply sprocket is connected to the pump shaft of the gear pump. The fertilizer supply drive sprocket is connected to the drive shaft. The drive chain is wound around the fertilizer supply drive sprocket and the fertilizer supply sprocket, and the drive chain meshes with the fertilizer supply sprocket and the fertilizer supply drive sprocket. The drive shaft drives the fertilizer supply sprocket to rotate through the drive chain and the fertilizer supply drive sprocket. The fertilizer supply sprocket provides power for the gear pump. The input end of the gear pump is connected to the fertilizer water tank in a through manner. The fertilizer spreading pipe is arranged at one end of the main body beam of the vehicle body close to the rear wheel steering device. The output end of the gear pump is connected to the fertilizer spreading pipe in a through manner. The drive shaft drives the gear pump to rotate and work through the drive chain, the fertilizer supply drive chain and the fertilizer supply sprocket to pump out the liquid fertilizer from the fertilizer water tank and pump it to flow out of the fertilizer spreading pipe, realizing fertilization. Since the gear pump is in a linkage relationship with the wheels, it automatically works when the vehicle is running and automatically stops when the vehicle stops. The liquid flow rate changes linearly with the vehicle speed.

[0007] Further, an auxiliary beam control mechanism is provided between the dynamic auxiliary beam and the main body beam of the vehicle body. The auxiliary beam control mechanism includes an adjusting screw rod, a control base, a hinge frame, a driven arc-shaped gear ring, a linkage rod, and a buffer spring. The control base is arranged on the main body beam of the vehicle body. The control base is provided with a threaded hole that penetrates up and down. The adjusting screw rod is rotatably threaded through the control base, and the adjusting screw rod is threadedly connected to the threaded hole. The hinge frame is hinged on the main body beam of the vehicle body. The driven arc-shaped gear ring is arranged at one end of the hinge frame close to the adjusting screw rod. Tooth rings are provided on the side wall of the driven arc-shaped gear ring close to the adjusting screw rod. The driven arc-shaped gear ring is threadedly meshed with the side wall of the adjusting screw rod. The buffer spring is arranged on the side wall of the hinge frame and is between the hinge frame and the dynamic auxiliary beam. The linkage rod is slidably arranged on the buffer spring. One end of the dynamic auxiliary beam away from the drive shaft is hinged to the lower end of the linkage rod. The buffer spring is sleeved on the linkage rod. The front section of the seeding plow blade is streamlined. When the seeding plow blade encounters substances that cannot be plowed, it will slide across the surface of the substances and at the same time lift the dynamic auxiliary beam. One end of the dynamic auxiliary beam away from the drive shaft moves upward. Since a buffer spring is also provided on the auxiliary beam control mechanism, it effectively buffers the impact force coming from the dynamic auxiliary beam to protect the entire system from being easily damaged in a harsh environment. By rotating the adjusting screw rod, the adjusting screw rod moves up and down along the control base. The up and down movement of the adjusting screw rod drives the driven arc-shaped gear ring to rotate upward or downward. The driven arc-shaped gear ring drives the hinge frame to rotate upward or downward. The hinge frame drives the linkage rod to move up and down. The linkage rod drives the dynamic auxiliary beam to rotate upward or downward around the drive shaft. When the vehicle is in the seeding state, the dynamic auxiliary beam is in the lowered state and is horizontal with the ground. The cutting edges of the main plow blade and the seeding plow blade are both below the ground surface, and the depth is determined by the initial installation position of the cutting edge. When it is necessary to move for transfer, rotate the adjusting screw rod in the reverse direction. The adjusting screw rod moves upward along the control base. The upward movement of the adjusting screw rod drives the driven arc-shaped gear ring to rotate upward. The driven arc-shaped gear ring drives the hinge frame to rotate upward. The hinge frame drives the linkage rod to move upward. The linkage rod drives the dynamic auxiliary beam to rotate upward around the drive shaft. The rear part of the dynamic auxiliary beam is lifted upward, and the main plow blade and the seeding plow blade are separated from the ground contact.

[0008] Furthermore, the main plow blade includes a plow blade body, a fixed seat, a triangular clamping member, an inclined slot, and a relief spring. The fixed seat is arranged on the dynamic auxiliary beam. A rotation through-hole penetrating up and down is provided on the fixed seat. The middle part of the plow blade body is hinged in the rotation through-hole. The triangular clamping member is arranged on the fixed seat on one side of the rotation through-hole. The triangular clamping member is arranged in a right triangle, and the hypotenuse of the triangular clamping member is close to the rotation through-hole. The inclined slots are evenly distributed at equal intervals on the inclined surface of the triangular clamping member. One end of the relief spring is arranged at the upper end of the plow blade body, and the other end of the relief spring is clamped in the inclined slot. By clamping the relief spring in the inclined slots at different heights, the inclination angle of the plow blade body can be adjusted. When the main plow blade works on the gobi gravel ground surface, it will bear a large impact force. Therefore, the designed strength is relatively large. However, there are still insurmountable large stones or substances that cannot be plowed. At this time, the main plow blade will overcome the spring force brought by the relief spring and make a backward relief movement to ensure that the cutter head and the auxiliary beam system are not damaged.

[0009] Furthermore, a hinge base is provided on the side wall of one end of the main body beam of the vehicle close to the rear wheel steering device. The fertilizer spreading pipe is hinged on the hinge base. Multiple groups of fertilizer spreading slots are provided on the hinge base. A tension spring is provided at the upper end of the fertilizer spreading pipe. One end of the tension spring is fixedly connected to the side wall of the fertilizer spreading pipe, and the other end of the tension spring is clamped in the fertilizer spreading slot. The fertilizer spreading pipe is maintained at the best fertilizer spreading angle by the spring force. Multiple groups of fertilizer spreading pipes are provided at equal intervals on the main body beam of the vehicle. The fertilizer spreading pipe is made of high-strength stainless steel pipe. A metal fin is provided at the front end of the outlet of the fertilizer spreading pipe. The lower end of the fertilizer spreading pipe is 1-3 cm below the ground surface. Preferably, the lower end of the fertilizer spreading pipe is 2 cm below the ground surface. When encountering hard objects or obstacles, the fertilizer spreading pipe can overcome the spring force and make a relief movement by rotating counterclockwise by a certain angle to protect the fertilizer spreading pipe. By clamping the tension spring in the fertilizer spreading slots at different heights, the entire tail fertilizer spreading pipe system can be manually controlled to retract, and the fertilizer spreading pipe is horizontal to the ground to ensure that the vehicle does not interfere with driving in the non-operating state.

[0010] Furthermore, a return pipe is provided in a through manner between the output end of the gear pump and the fertilizer tank. A return valve is provided on the return pipe. The return valve is opened when the vehicle is transferred and driving without the need for fertilizer spreading, so that the fertilizer flows back into the fertilizer storage tank.

[0011] Furthermore, the rear-wheel steering device includes rear wheels, a steering seat, a steering linkage rod, and a steering valve. The steering seat is rotatably arranged below the main body beam of the vehicle body, and the rear wheels are rotatably arranged on the steering seat. There are multiple sets of rear wheels and steering seats below the main body beam of the vehicle body. The rear wheels use wide-body tires, and the distance between adjacent two sets of rear wheels is greater than the diameter of the rear wheels and greater than the length of the steering seat, ensuring the movement space for the steering seat and the rear wheels to turn. The steering linkage rod is arranged on one side of the steering seat, and the steering seat is hinged to the steering linkage rod. Multiple sets of steering seats are connected by the steering linkage rod. The steering valve is arranged at the upper end of the steering linkage rod. The steering valve drives the steering linkage rod to move left and right, and the steering linkage rod drives multiple sets of steering seats and rear wheels to rotate to adjust the driving direction, so as to avoid obstacles and good vegetation, or travel along a predetermined arc route. Each single rear wheel rotates around the contact point between its own center point and the ground as the axis, and the whole row of rear wheels rotates simultaneously, and the rotation is controlled manually. When the vehicle is sowing in the mode of being towed by a front vehicle, the direction is fixed to the straight-ahead position without moving.

[0012] The beneficial effects achieved by the present invention with the above structure are as follows: The sand and gobi vegetation planting equipment of this solution is reasonably designed and easy to operate. The secondary beam hanging type ploughing and sowing mechanism is set up to facilitate ploughing and sowing at the same time, and it is suitable for working on gobi gravel ground. The plough blades are dynamically and automatically adjusted, and automatically avoid substances that cannot be ploughed open, ensuring that the cutter head and the auxiliary beam system are not damaged. The liquid fertilizer is pressurized by a gear pump, and the power source of the gear pump is transmitted through a sprocket chain connected to the driving wheel. The power of the gear pump changes with the vehicle speed. The liquid fertilizer is spread under the ground, and the liquid fertilizer is spread in time after sowing, increasing the control of the rear-wheel direction, enabling the equipment to conveniently control the forward trajectory in a non-farmland environment, effectively improving the sand and gobi vegetation planting efficiency, reducing the use of manual labor, and lowering the construction cost.

[0028] During actual use, the vehicle can be driven by self-propulsion, or can be towed and moved forward by a power device such as a tractor. First, liquid fertilizer is injected into the fertilizer storage water tank 25, and seeds are placed in the seed storage box 23. The main body beam 1 of the vehicle bears the weight of all the equipment on the vehicle. When driving by self-propulsion, the engine 7 rotates to provide power for the vehicle to travel. The engine 7 drives the drive shaft 9 to rotate through the drive sprocket 11, the driving sprocket 10 and the drive chain 12, thereby driving the drive wheel 8 to rotate, providing power for the vehicle to travel;The driving wheel 8 rotates. The dynamic auxiliary beam 2 only moves forward with the vehicle and does not rotate with the drive shaft 9. When the vehicle is in the sowing state, the dynamic auxiliary beam 2 is in the lowered state and is horizontal with the ground. The cutting edges of the main plow blade 21 and the sowing plow blade 20 are both below the ground surface, and the depth is determined by the initial installation position of the cutting edge. The dynamic auxiliary beam 2 drives the main plow blade 21 to plow the sandy surface. The inclination angle of the plow blade body 38 can be adjusted by clamping the avoidance spring 42 in the diagonal slots 41 at different heights. When the main plow blade 21 works on the gobi gravel ground surface, it will bear a large impact force, so it is designed with a relatively large strength. However, there are still insurmountable large stones or substances that cannot be plowed. At this time, the main plow blade 21 will overcome the spring force of the avoidance spring 42 and make a backward avoidance action to ensure that the cutting edge and the auxiliary beam system are not damaged. Before the vehicle moves forward, the speed-changing gear 16 is set. The speed-changing gear 16 is convenient for adjusting the rotational speed of the power shaft of the automatic seeding box 15 so as to adjust the seeding speed. After the speed-changing gear 16 is set, the rotational speed required by the power shaft of the automatic seeding box 15 can be obtained. The drive shaft 9 drives the power shaft of the automatic seeding box 15 to rotate through the speed-changing gear 16 and the seeding sprocket chain mechanism 18, thereby driving the automatic seeding box 15 to work and sow seeds. The manual clutch 17 disconnects the power shaft of the automatic seeding box 15 from the driving wheel 8 when the vehicle is in transit, stopping the seeding. The seeds sown by the automatic seeding box 15 are conveyed through the seeding conduit 19 into the seeding through-holes 24 of the lower sowing plow blade 20 and sown in the sandy land plowed by the main plow blade 21 and the sowing plow blade 20. The number of rows to be sown by the vehicle is determined by the number of the main plow blade 21 and the sowing plow blade 20 and corresponds to the number of the automatic seeding boxes 15. When the sowing plow blade 20 encounters substances that cannot be plowed, it will slide across the surface of the substances and at the same time lift the dynamic auxiliary beam 2. The end of the dynamic auxiliary beam 2 far from the drive shaft 9 moves upward. Since there is also a buffer spring 37 on the auxiliary beam control mechanism 31, it effectively buffers the impact force coming from the dynamic auxiliary beam 2 to protect the whole system from being easily damaged in a harsh environment. During the vehicle's driving process, the drive shaft 9 drives the fertilizer supply sprocket to rotate through the drive chain 27 and the fertilizer supply drive sprocket 29. The fertilizer supply sprocket provides power for the gear pump 26. The gear pump 26 is driven to rotate through the drive chain 27, the fertilizer supply drive chain and the fertilizer supply sprocket to pump the liquid fertilizer out of the fertilizer tank 25 and pump it out through the fertilizer spreading pipe 30 to achieve fertilization. Because the gear pump 26 is in a linkage relationship with the wheels, it works automatically when the vehicle is driving and stops automatically when the vehicle stops. The liquid flow rate changes linearly with the vehicle speed. When encountering hard objects or obstacles, the fertilizer spreading pipe 30 can overcome the spring force and rotate counterclockwise by a certain angle to make an avoidance action to protect the fertilizer spreading pipe 30;It is clamped in the fertilizer broadcasting slots 45 at different heights through the tension spring 14. The entire rear fertilizer broadcasting pipe 30 system can be manually controlled to retract. The fertilizer broadcasting pipe 30 is horizontal to the ground to ensure that it does not interfere with the vehicle's driving when the vehicle is in a non-operating state. The steering valve 28 drives the steering linkage rod 51 to move left and right. The steering linkage rod 51 drives multiple groups of steering seats 50 and the rear wheels 49 to rotate to adjust the driving direction, so as to bypass obstacles and good vegetation, or drive along a predetermined arc route. A single rear wheel 49 rotates around the axis of its own center point and the ground contact point. The entire row of rear wheels 49 rotates simultaneously, and the rotation is manually controlled. When it is necessary to move the field, the manual clutch 17 is controlled to disconnect the power shaft of the automatic seeding box 15 from the driving wheel 8, and the adjusting screw rod 32 is rotated in the reverse direction. The adjusting screw rod 32 moves upward along the control base 33. The upward movement of the adjusting screw rod 32 drives the driven arc-shaped gear ring 35 to rotate upward. The driven arc-shaped gear ring 35 drives the articulated frame 34 to rotate upward. The articulated frame 34 drives the linkage rod 36 to move upward. The linkage rod 36 drives the dynamic auxiliary beam 2 to rotate upward around the drive shaft 9. The rear part of the dynamic auxiliary beam 2 is lifted upward, and the main plow blade 21 and the seeding plow blade 20 are separated from the ground contact. The return valve 48 is opened when fertilizer broadcasting is not required during the vehicle's transfer driving, so that the fertilizer flows back into the fertilizer storage water tank 25; when the vehicle selects the front vehicle traction method for seeding, the direction of the rear wheels 49 is controlled by the steering valve 28 and the steering linkage rod 51 to be fixed in the straight-ahead position. At this time, the auxiliary beam control mechanism 31 is not limited to the screw principle shown in the figure, and can also be electric or pneumatic.;
