Description
Technical Field
[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to a tillage device with adjustable plow frame height. Background Technology
[0002] Currently, most commonly used tillage devices rely on manual adjustment of relevant components. Frequent manual adjustments not only increase the workload of operators but also significantly reduce the operating efficiency of the tillage device, failing to meet the demands of modern agriculture for efficient tillage.
[0003] Existing rotary tillage devices commonly suffer from slippage when working on clay soil. As the surface of the plowshare easily becomes stuck with soil, the tillage effect is poor and the work efficiency is low.
[0004] At the same time, the tire design of existing tillage devices also has obvious defects. When facing clay soil, the tires of existing tillage devices are prone to slipping or sinking into the ground, which seriously affects the stability and operating efficiency of the tillage device. This problem is particularly prominent during the rainy season or under conditions of high soil moisture, causing great inconvenience and losses to agricultural production. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a tillage device with adjustable plow frame height.
[0006] The technical solution of this utility model is:
[0007] An adjustable plow frame tillage device includes a frame, a handle connected to the frame, a drive system mounted on the frame, a plow frame connected to the frame, a forward roller connected to the frame at the front end of the plow frame, and support wheels connected to the frame on both sides of the rear end of the plow frame. The drive system is characterized in that it is connected to the forward roller and the support wheels respectively; the plow frame includes two crossbeams, and a height adjustment assembly is provided between the crossbeams and the plow frame; the crossbeams are movably connected to the plow rod.
[0008] Furthermore, the height adjustment assembly includes a housing connected to the frame, a threaded rod inside the housing, a through hole corresponding to the threaded rod on the frame, the threaded rod passing through the through hole and fixedly connected to the crossbeam, a threaded cylinder outside the threaded rod, a secondary gear fixedly connected to the outside of the threaded cylinder, a bearing seat at the bottom of the secondary gear, the bearing seat fixed on the frame, the threaded cylinder rotatably connected inside the bearing seat, and the threaded rod threadedly connected to the threaded cylinder.
[0009] Furthermore, a drive motor is provided at the top of the housing, the output end of the drive motor is connected to a rotating rod, and the bottom end of the rotating rod is connected to a main gear that meshes with the secondary gear.
[0010] Furthermore, the plow handle is provided with a spacing adjustment pin, and the crossbeam is provided with a plurality of spacing adjustment holes corresponding to the spacing adjustment pin. The plow handle is movably connected to the crossbeam by the spacing adjustment pin passing through the spacing adjustment holes.
[0011] Furthermore, the end of the plowshare away from the crossbeam is inclinedly connected to the plow head.
[0012] Furthermore, the plowshare is composed of two inwardly concave arc-shaped panels welded together.
[0013] Furthermore, the surface of the forward roller has several horizontal strip-shaped protrusions.
[0014] Furthermore, a scraper is provided in front of the forward roller, the scraper is fixed obliquely on the frame, and the end of the scraper away from the frame is in contact with the forward roller.
[0015] Furthermore, the surface of the support wheel has several protrusions of varying lengths.
[0016] Furthermore, several support beams are fixedly connected between the crossbeams.
[0017] The beneficial effects of this utility model are:
[0018] (1) This utility model sets up a height adjustment component, which drives the main gear to rotate by the drive motor. The two auxiliary gears meshing with it rotate synchronously, thereby causing the threaded cylinder to rotate inside the bearing seat. During the rotation of the threaded cylinder, the internal threaded rod can achieve vertical displacement adjustment, and the crossbeam connected to the threaded rod will also move up and down, ultimately driving the plow frame to adjust the height synchronously. Compared with traditional manual adjustment, this utility model greatly improves the adjustment efficiency and ensures the adjustment accuracy. It can quickly adapt to the plowing needs under different terrain and soil conditions, and significantly improve the operational adaptability and working efficiency of the plowing device.
[0019] (2) This utility model is designed for clay soil. It replaces the traditional rotary plow with a horizontally moving plow, which avoids the problem of the rotary plow slipping when working on clay soil. This utility model is equipped with a forward roller on the tillage device. The forward roller supports the entire tillage device and enhances the stability of the tillage device when working in the field. On the other hand, the forward roller has a large contact area with the soil. When encountering poor working conditions such as clay mud, it can greatly reduce the risk of the tillage device getting stuck in the mud and stopping work. In addition, the surface of the forward roller is designed with multiple raised structures. These raised structures can effectively increase the friction between the device and the ground during operation, play a good anti-slip role, and further improve the safety and reliability of the tillage device when driving and working in various complex terrains.
[0020] (3) This utility model can flexibly adjust the spacing between plows to adapt to different operational needs and effectively enhance the versatility of the tillage device; through the adjustable spacing structure layout, it avoids the problem of uneven soil treatment caused by missed tillage in the gap area during operation due to the traditional fixed spacing, and ensures that the soil is tilled evenly and comprehensively.

Detailed Implementation
[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the embodiments described are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0028] like Figure 1 and Figure 2 As shown, a tillage device with adjustable plow frame height includes a frame 1, a handle 4 connected to the frame 1, a drive system 2 mounted on the frame 1, a plow frame 7 connected to the frame 1, a forward roller 5 connected to the frame 1 at the front end of the plow frame 7, and support wheels 8 connected to the frame 1 on both sides of the rear end of the plow frame 7. The drive system 2 is connected to the forward roller 5 and the support wheels 8 respectively; the plow frame 7 includes two crossbeams 9, and a height adjustment assembly 3 is provided between the crossbeams 9 and the plow frame 7; the crossbeams 9 are movably connected to the plow rod 13.
[0029] The forward roller 5 and support wheel 8 of the tillage device can provide stable support for the tillage device, enabling it to move smoothly; the forward roller 5 has a large contact area with the soil, making it less likely to get stuck in muddy soil and interrupt operation; the spacing between the plow blades 13 is adjustable, improving the versatility of the tillage device and meeting different tillage needs.
[0030] like Figure 3 As shown, the height adjustment assembly 3 includes a housing 3-1 connected to the frame 1. A threaded rod 3-2 is located inside the housing 3-1. A through hole corresponding to the threaded rod 3-2 is provided on the frame 1 (not shown in the figure, the rest are the same). The threaded rod 3-2 passes through the through hole and is fixedly connected to the crossbeam 9. A threaded cylinder 3-3 is provided outside the threaded rod 3-2. A secondary gear 3-4 is fixedly connected to the outside of the threaded cylinder 3-3. A bearing seat 3-5 is provided at the bottom of the secondary gear 3-4. The bearing seat 3-5 is fixed on the frame 1. The threaded cylinder 3-3 is rotatably connected inside the bearing seat 3-5. The threaded rod 3-2 is threadedly connected to the threaded cylinder 3-3.
[0031] The housing 3-1 of the height adjustment component 3 ensures that the entire height adjustment component 3 will not shift due to vibration or other factors during the operation of the tillage device, and provides support for other structures, ensuring the accuracy and reliability of the adjustment. When the threaded rod 3-2 moves up and down inside the threaded cylinder 3-3, it can precisely drive the crossbeam 9 to achieve synchronous up and down adjustment, so as to flexibly and accurately change the depth of the plow head into the soil according to different tillage requirements. The threaded cylinder 3-3 is equipped with a secondary gear 3-4 on the outside, and the bottom is mounted on the bearing seat 3-5 fixed to the frame 1. When the secondary gear 3-4 rotates, it can drive the threaded cylinder 3-3 to rotate smoothly in the bearing seat, and then use the characteristics of the threaded connection to convert the circular motion into the linear motion of the threaded rod 3-2, so as to achieve stable adjustment of the height of the crossbeam 9.
[0032] Specifically, a drive motor 3-7 is provided at the top inside the outer casing 3-1. The output end of the drive motor 3-7 is connected to a rotating rod 3-6, and the bottom end of the rotating rod 3-6 is connected to a main gear 3-8 that meshes with the secondary gear 3-4.
[0033] Powered by a drive motor 3-7, the main gear 3-8 rotates after startup. Thanks to the precise meshing transmission between the gears, the main gear 3-8 can efficiently drive the two meshing auxiliary gears 3-4 to operate synchronously, thereby precisely driving the two crossbeams 9 to complete the height adjustment synchronously. This technical solution operates automatically throughout the entire process, greatly saving labor costs. At the same time, relying on the precise gear transmission system, it can achieve precise control.
[0034] like Figure 4 and Figure 5 As shown, the plow handle 13 is equipped with a spacing adjustment pin 14, and the crossbeam 9 has multiple spacing adjustment holes corresponding to the spacing adjustment pin 14 (not shown in the figure, the rest are the same). The plow handle 13 is movably connected to the crossbeam 9 by the spacing adjustment pin 14 passing through the spacing adjustment holes. The spacing between the plow handles 13 can be flexibly adjusted according to different tillage needs, avoiding the problem of uneven soil treatment caused by missed tillage in the gap area during operation due to the traditional fixed spacing. The spacing adjustment pin 14 adjusts and fixes the position of the plow handle 13 by passing through the spacing adjustment holes on the crossbeam 9 with bolts and nuts.
[0035] Specifically, the end of the plowshare 13 away from the crossbeam 9 is inclined to connect to the plow head 6, and the inclined plow head 6 is easier to enter the soil for tilling.
[0036] In a preferred embodiment of this utility model, the plow head 6 is composed of two inwardly concave arc-shaped panels 15 welded together. The arc-shaped panels 15 can increase the contact area with the soil and improve the tillage efficiency.
[0037] like Figure 1 and Figure 2As shown, the surface of the forward roller 5 has several horizontal strip-shaped protrusions 10. These strip-shaped protrusions 10 can effectively increase the friction between the roller and the ground during operation, play a good anti-slip role, and further improve the safety and reliability of the tillage device in various complex terrains.
[0038] As a preferred embodiment of the present invention, a scraper 16 is provided in front of the forward roller 5. The scraper 16 is fixed at an angle on the frame 1. The end of the scraper 16 away from the frame 1 is in contact with the forward roller 5. The scraper 16 can remove the mud adhering to the uneven and irregular surface of the forward roller 5.
[0039] It should be noted that the scraper blade 16 is made of hard silicone plate. In this way, when the forward roller 5 moves forward, the scraper blade 16 can remove the mud stuck to the uneven and irregular surface of the forward roller 5 without affecting the forward movement of the forward roller 5.
[0040] As a preferred embodiment of the present invention, the surface of the support wheel 8 has a number of protrusions 11 of varying lengths. The protrusions 11 increase the friction between the support wheel 8 and the ground, thereby improving the stability and grip of the equipment.
[0041] In a preferred embodiment of this utility model, several support beams 12 are fixedly connected between the crossbeams 9. The support beams 12 increase the stability between the crossbeams 9 and the stability of the plow frame 7, thereby making the tillage work more efficient.
[0042] The above description is merely a preferred embodiment of this utility model. However, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, are all covered within the protection scope of this utility model.
