Description

[0001] The present invention relates to the technical field of agricultural tillage equipment, and specifically to an agricultural tillage equipment for planting with adjustable pit depth. Background Art

[0002] Planting is one of the main components of agriculture, including the cultivation of various crops, forest trees, fruit trees, medicinal and ornamental plants, etc. There are food crops, cash crops, vegetable crops, green manure crops, forage crops, pastures, horticultural crops such as flowers, etc. Planting occupies a particularly important position in the whole agriculture and is the foundation of the whole agriculture. However, agricultural mechanization is an important symbol of the development of modern agriculture. Its core lies in replacing traditional human and animal power with mechanical equipment to improve production efficiency and reduce labor intensity. For complex terrains such as mountains and slopes, shallow tillage and soil loosening are used to improve the soil structure, and in scenarios such as apple orchards and peach orchards, when loosening the soil, corresponding small tillage equipment is often needed for processing.

[0003] When the current agricultural tillage equipment for planting is in use, for the small tillage equipment used in complex terrains such as mountains and slopes, due to the terrain, it often requires manual holding to control the movement of the equipment. Since the equipment itself has a certain weight, it is easy to increase the fatigue degree of personnel during long-term holding work and adjusting the equipment angle. In areas where the soil is soft, the tillage equipment is prone to sink, resulting in difficult walking and even inability to operate normally. At the same time, it will further increase the difficulty and pressure of manual auxiliary holding.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. Through the drag reduction mechanism of the present invention, upward pushing can be generated on the air distribution cover and the working frame, reducing the contact pressure between the equipment and the soil, reducing the adhesion resistance of the soil to the equipment, making the movement of the working frame and the operation of personnel easier to master. At the same time, the gas reaction force can also provide a certain supporting force for the working frame. When the equipment encounters soft soil, the subsidence of the equipment can be reduced to ensure that the equipment works more smoothly. At the same time, since the gas reaction force relies on the self - supply energy of the engine, the resistance between the equipment and the soil is reduced, and the traction force and power consumption required for the equipment during operation are correspondingly reduced, thereby saving energy, improving energy utilization efficiency, reducing operation costs, and reducing the downtime and adjustment time caused by equipment jamming and subsidence. Furthermore, the overall operation efficiency is improved, the operation cycle is shortened, and the adaptability of the equipment to different terrains and soil conditions is enhanced.

[0020] 2. Through the cleaning mechanism, the present invention can automatically wash and clean the surface of the moving wheels, preventing the problem that the continuous adhesion of soil to the surface of the moving wheels increases the driving resistance of the equipment, helping the equipment to travel more smoothly in the field. At the same time, there is no need for manual cleaning of the moving wheels frequently, saving dedicated cleaning time, enabling the equipment to be more involved in tillage operations, and improving the overall work efficiency.

[0021] 3. Through the adjustment mechanism, the present invention can separately adjust the position between the moving wheels and the ground to ensure the contact effect between the moving wheels and the ground, enabling the wheels to still maintain a certain ground pressure to maintain sufficient friction, avoiding the problem of wheel slippage when the equipment moves upward and affecting the walking of the equipment. Thus, it is beneficial to further ensure the smoothness of the equipment during operation. At the same time, when the working frame is working properly, adjusting the moving wheels up and down can keep the chassis of the tillage equipment parallel to the ground in areas with undulations, potholes, as well as special terrains such as ridges and ditches, ensuring the smooth driving of the equipment and also being beneficial for adjusting the depth of the tillage pits.

[0022] 4. Through the leveling mechanism, the present invention can pre-flatten the ground in front of the air distribution hood, avoiding the air distribution hood being blocked by mud blocks, and the leveled ground makes the reaction force effect of the airflow in the air distribution hood better, thus being beneficial to improving the drag reduction and support effects.

Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] To solve the technical problems that the tillage equipment is prone to sink, resulting in difficult walking and even inability to operate normally, and at the same time, it will further increase the difficulty and pressure of manual auxiliary holding, such as Figures 1 - 7As shown in the figure, the following preferred technical solutions are provided: An agricultural tillage device with adjustable pit depth, including a working frame 1 and a drag reduction mechanism 4 arranged below the front side of the power mechanism 3. A control box 2 is installed above the rear side of the working frame 1. A power mechanism 3 is arranged in the middle above the working frame 1. The power mechanism 3 includes an engine 301 installed in the middle of the surface of the working frame 1. Two groups of power shafts 302 are rotatably connected to the output ends on both sides of the engine 301. And the front end of each group of power shafts 302 is rotatably connected to a transmission chain 303. The output end of the transmission chain 303 is rotatably connected to a moving wheel 304. The power shaft 302 is slidably connected to the moving wheel 304 through the transmission chain 303. Through the transmission chain 303, the rotation of the moving wheel 304 is realized by using a gear and a rotating shaft fixedly connected to the gear below it;

[0037] Three groups of mounting seats 305 are installed below the rear part of the working frame 1. And a rotating screw 306 is arranged in the middle above each group of mounting seats 305. A plough harrow 307 is fixed to the lower surface of the mounting seat 305. And guide rods 308 are fixed to both sides of the upper surface of the mounting seat 305. The plough harrow 307 and the mounting seat 305 are slidably connected to the working frame 1 through the rotating screw 306 and the guide rod 308. And the rotating screw 306 is threadedly connected to the working frame 1;

[0038] Through an engine 301 using one of diesel, gasoline or electric hybrid, which is commonly used in existing small tillage devices, the two groups of power shafts 302 can be driven to rotate synchronously. Thus, the rotational force can be transmitted to the moving wheel 304 by using the transmission chain 303 and the rotating shaft. So that the moving wheel 304 can finally drive the overall movement of the working frame 1. The plough harrow 307 behind the working frame 1 can till the land when the working frame 1 moves. Through the cooperation of the rotating screw 306 and the guide rod 308, the height between the mounting seat 305 and the plough harrow 307 and the working frame 1 can be adjusted. Thus, the position of the plough harrow 307 can be adjusted according to the situation during the operation of the device to adjust the pit depth;

[0039] The drag reduction mechanism 4 includes a synchronous wheel 401 installed on the power shaft 302. A piston cylinder 402 is arranged in front of the synchronous wheel 401. And a camshaft 403 is installed below the inner side of the piston cylinder 402. A piston shaft 404 is rotatably connected above the camshaft 403. The synchronous wheel 401 is rotatably connected to the camshaft 403 through the piston cylinder 402. The piston shaft 404 is slidably connected to the piston cylinder 402 through the camshaft 403. The front end above the piston cylinder 402 is connected to an air duct 405. And a one-way valve 406 is installed on one side of the top of the piston cylinder 402;

[0040] A gas storage base 407 is connected below the air duct 405, and an air vent pipe 408 is connected below the gas storage base 407. A gas distribution hood 409 is arranged at the bottom of the air vent pipe 408, and a high-pressure spray head 410 is installed below the interior of the gas distribution hood 409. The piston cylinder 402 is communicated with the gas storage base 407, the air vent pipe 408, the gas distribution hood 409 and the high-pressure spray head 410 through the air duct 405;

[0041] Mounting frames 411 are installed on both side surfaces of the gas distribution hood 409, and rolling wheels 412 are arranged in the middle of the mounting frames 411. Pressure sensors 413 are installed above the front and rear ends of the mounting frames 411, and a first scraping plate 414 is fixed on one side inside the mounting frames 411. The mounting frames 411 are elastically connected to the gas distribution hood 409 through the rolling wheels 412 and the pressure sensors 413. Through the drag reduction mechanism 4, the pressure between the whole working frame 1 and the ground can be reduced, which is beneficial to reducing the difficulty of manual holding operation by personnel and preventing the problem that the equipment is prone to sink in areas with soft soil;

[0042] Through the synchronous pulley 401, the power during the operation of the power shaft 302 on the engine 301 can be utilized, enabling the camshaft 403 to be driven to rotate, thereby enabling the piston shaft 404 to be driven by the camshaft 403 to move up and down within the piston cylinder 402. By using the one-way valve 406 for one-way intake, the gas can be rapidly and continuously compressed when the piston shaft 404 moves. The compressed gas is stored in the gas storage seat 407 through the gas guide pipe 405. Through the transfer of the gas via the gas vent pipe 408, the compressed gas can finally be ejected from the high-pressure nozzles 410 inside the air distribution hood 409. The air distribution hood 409 contacts and rolls on the ground by means of the rolling wheels 412. Thus, when the high-pressure nozzles 410 jet high-pressure air downward, the air pressure will generate a reaction force inside the air distribution hood 409 to push the air distribution hood 409 and the working frame 1 upward, reducing the contact pressure between the equipment and the soil. This can reduce the adhesion resistance of the soil to the equipment, making the movement of the working frame 1 and the operation of personnel easier to master. At the same time, the gas reaction force can also provide a certain supporting force to the working frame 1. When the equipment encounters soft soil, it can reduce the subsidence of the equipment to ensure the smooth operation of the equipment. Through the pressure sensor 413 based on existing principles and existing control principles, the contact between the rolling wheels 412 and the ground can be monitored. When the pressure between the rolling wheels 412 and the ground weakens, it can be judged that the ground on which the equipment is traveling is relatively soft. At this time, the power of the equipment can be increased to increase the air jet pressure of the high-pressure nozzles 410, which is conducive to further preventing the possibility of the working frame 1 from subsiding. At the same time, since the reaction force of the gas relies on the self-supply of energy of the engine 301, the resistance between the equipment and the soil is reduced, and the traction force and power consumption required for the equipment during operation are correspondingly reduced, thereby saving energy, improving the energy utilization efficiency, reducing the operation cost, and reducing the downtime and adjustment time caused by equipment jamming and subsidence. Furthermore, the overall operation efficiency is improved, the operation cycle is shortened, and the adaptability of the equipment to different terrains and soil conditions is enhanced. The model of the pressure sensor 413 can be SBT641.

[0043] To solve the technical problems that the equipment is prone to adhering to soil, resulting in an increase in the driving resistance of the equipment and avoiding equipment slippage, such as Figure 1 and Figure 2 and Figures 8 - 10As shown in the figure, the following preferred technical solutions are provided: Cleaning mechanisms 5 are arranged on both sides of the drag reduction mechanism 4. The cleaning mechanism 5 includes a shielding cover 501 installed above the outside of the moving wheel 304. A gas distribution plate 502 is arranged on the rear surface of the shielding cover 501. A sub-air pipe 503 is connected to the rear side of the gas distribution plate 502. An electromagnetic valve 504 is installed at the bottom of the sub-air pipe 503. A flushing nozzle 505 is installed at the front end of the gas distribution plate 502. The gas storage base 407 is connected to the gas distribution plate 502 and the flushing nozzle 505 through the electromagnetic valve 504 and the sub-air pipe 503. Through the cleaning mechanism 5, the surface of the moving wheel 304 can be flushed and cleaned.

[0044] Through the electromagnetic valve 504, the compressed gas in the gas storage base 407 can be shunted. By using the sub-air pipe 503 and the gas distribution plate 502, the shunted gas is finally ejected from the high-pressure flushing nozzle 505. The air outlet angle of the flushing nozzle 505 faces the outer surface of the moving wheel 304, so that the surface of the moving wheel 304 can be automatically flushed and cleaned, preventing the problem that the surface of the moving wheel 304 continuously adheres to soil, resulting in an increase in the driving resistance of the equipment. This helps the equipment to travel more smoothly in the field. At the same time, there is no need for manual frequent cleaning of the moving wheel 304, saving dedicated cleaning time, enabling the equipment to be more involved in tillage operations, and improving the overall work efficiency.

[0045] Adjusting mechanisms 6 are arranged inside both sides of the power mechanism 3. The adjusting mechanism 6 includes a support frame 601 connected to the rotating shaft of the moving wheel 304. A connecting rod 602 is arranged in the middle above the support frame 601. A connecting spring 603 is arranged in the middle of the connecting rod 602. A sliding wheel 604 is installed at the top of the connecting rod 602.

[0046] An inclined push plate 605 is arranged on one side of the top of the sliding wheel 604. A first electric push cylinder 606 is installed behind the inclined push plate 605. A support spring column 607 is installed in the middle below the support frame 601. The support frame 601 is slidably connected to the side wall of the working frame 1 through the connecting rod 602, the sliding wheel 604, the inclined push plate 605 and the first electric push cylinder 606. The support frame 601 is elastically connected to the working frame 1 through the support spring column 607. Through the adjusting mechanism 6, the height of the moving wheel 304 can be adjusted separately to ensure the grip of the equipment during driving.

[0047] The tilt push plate 605 can be pushed forward by the first electric push cylinder 606. Thus, under the action of the inclined plane and with the deformation support of the support spring columns 607, the vertical position of the support frame 601 can be adjusted, so that the support frame 601 drives the moving wheels 304 to adjust the vertical height with respect to the working frame 1. When the distance between the working frame 1 and the ground increases due to the upward counter-push of air pressure, the position between the moving wheels 304 and the ground can be adjusted independently to ensure the contact effect between the moving wheels 304 and the ground, so that the wheels can still maintain a certain ground contact pressure to maintain sufficient friction and avoid the problem of wheel slippage when the equipment moves upward, which affects the walking of the equipment. This is conducive to further ensuring the smoothness of the equipment during operation. At the same time, when the working frame 1 is working normally, adjusting the moving wheels 304 up and down can keep the chassis of the tillage equipment parallel to the ground in areas with high and low undulations, potholes, and special terrains such as ridges and ditches, ensuring the stable driving of the equipment and also being conducive to adjusting the depth of the tillage pits.

[0048] To solve the technical problem that uneven land affects the effect of air impact reaction, as Figure 1 , Figure 2 and Figure 11 shown, the following preferred technical solutions are provided: A leveling mechanism 7 is provided below the front end of the working frame 1. The leveling mechanism 7 includes a fixed cover 701 installed at the front end above the working frame 1. A second electric push cylinder 702 is installed in the middle of the inner side of the fixed cover 701, and a support cover 703 is installed below the second electric push cylinder 702. The support cover 703 is slidably connected to the working frame 1 through the second electric push cylinder 702. A rolling roller 704 is installed in the middle of the inner side of the support cover 703, and a second scraper 705 is provided above one side of the rolling roller 704. Through the leveling mechanism 7, the ground can be flattened to ensure the effect of jet counter-push.

[0049] Through the second electric push cylinder 702, the support cover 703 and the rolling roller 704 can be driven to move up and down, so that the rolling roller 704 can be pressed against the ground. Thus, when the working frame 1 is traveling, the ground in front of the air distribution cover 409 can be flattened in advance to avoid the air distribution cover 409 being blocked by mud blocks, and the flattened ground makes the reaction force effect of the airflow in the air distribution cover 409 better, which is conducive to improving the drag reduction and support effects.
