Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, specifically to an agricultural tillage machine. Background Technology

[0002] Tillers are tillage machines that work in conjunction with tractors to perform tillage and harrowing operations. They are widely used because of their strong soil-breaking ability and the ability to flatten the ground after tillage. At the same time, they can chop up the stubble buried below the surface, making it easier for the seeder to operate and providing a good seedbed for later sowing.

[0003] Current tillage machines require a drive motor and drive shaft to rotate the plow blades, which loosen and turn the soil. However, the soil varies in size depending on the planting area. Currently, the plow blades on tillage machines are directly welded to the drive shaft at intervals, making it impossible to adjust the spacing between the blades. This prevents the tillage machine from loosening soil of different sizes. Furthermore, during the loosening process, people around the tillage machine are easily injured by the rotating plow blades, posing a safety hazard. Therefore, an adjustable-spacing rotary tillage machine is proposed.

[0004] Therefore, it is necessary to invent an agricultural machinery tiller. Utility Model Content

[0005] The purpose of this invention is to solve the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an agricultural machinery tiller, including a fixed frame and a connecting arm, the connecting arm being hinged to the upper end of the fixed frame, side plates being symmetrically installed on both sides of the fixed frame, a drive shaft being rotatably connected to the middle of the side plates, positioning components being installed at intervals on the outside of the drive shaft, and plow blades being installed at intervals on the surface of the positioning components.

[0007] Based on the above features: the end of the connecting arm away from the fixed frame is connected to the front or rear of the vehicle. The connection is fixed by multiple bolts, which makes it convenient to push the entire fixed frame to move when the vehicle starts. At this time, the fixed frame can be dragged above the soil, and the drive shaft can drive the plow blade to rotate through the positioning component, which makes it convenient to use the plow blade to turn over the soil.

[0008] Preferably, a fixing rod is installed at the front end of the fixing frame, a sleeve is movably fitted on the outside of the fixing rod, and a protective cover is fixedly welded to the outside of the sleeve, the protective cover having a semi-arc structure.

[0009] Based on the above characteristics: after the protective cover is adjusted to the required angle, the sleeve and the fixing rod can be locked together with bolts to prevent people in the vicinity from being accidentally injured by the plow blades.

[0010] Preferably, a drive motor is installed on one side of the outer end of the side plate, a bearing is provided on the inner wall of one side of the drive motor, and the two ends of the drive shaft are rotatably connected to the bearing.

[0011] Based on the above features: when the drive motor starts, it can drive the drive shaft to rotate. When the drive shaft rotates, it can drive the plow blades to rotate through the positioning component, making it convenient to use the plow blades to turn over the soil.

[0012] Preferably, the drive shaft surface is provided with spaced-apart fixing holes, and the surface of the fixing holes is provided with a dustproof film.

[0013] Based on the above features: the fixed socket allows for easy positioning of the component after adjustment and fixation to the outside of the drive shaft.

[0014] Preferably, the dustproof film has a cross-shaped cut in the middle, and the dustproof film is made of rubber material.

[0015] Based on the above characteristics: when no workpiece is inserted into the fixed socket, the dustproof film will unfold into a planar shape to block the fixed socket from dust through its own elastic potential energy. When the workpiece is inserted into the fixed socket, the dustproof film will fold down on its own and will not affect the insertion of the workpiece.

[0016] Preferably, the positioning component includes a positioning disk and a movable hole on the surface of the positioning disk, the movable hole having a central hole in the middle, and lugs symmetrically welded on both sides of the positioning disk.

[0017] Based on the above features: the positioning disc has two semi-circular structures that are aligned and connected to each other. A hole is opened in the middle of the lug to facilitate screws to pass through and lock. At this time, both the positioning disc and the central hole will be circular structures. When it is necessary to adjust the distance between adjacent plow blades, the positioning disc can be moved outside the drive shaft.

[0018] Preferably, the positioning disk has threaded holes at the middle of both ends, and locking screws are threaded into the threaded holes.

[0019] Based on the above features: when the fixed socket is aligned with the threaded hole, the locking screw is inserted through the threaded hole into the fixed socket for fixation.

[0020] Preferably, the plow blade has an arc-shaped structure, and one end of the plow blade has a through hole, with a fixing bolt connected inside the through hole.

[0021] Based on the above features: the through hole on one side of the plow blade is aligned with the movable hole, and then the plow blade is secured by a fixing bolt that passes through the through hole and the movable hole.

[0022] The beneficial effects of this utility model are:

[0023] 1. The positioning component allows for adjustment of the spacing between adjacent plow blades. When adjustment is needed, the positioning plate can be moved outside the drive shaft. The fixed insertion hole and the threaded hole have the same diameter. Once the position is reached, the fixed insertion hole and the threaded hole are aligned. Then, a locking screw is inserted through the threaded hole and fixed inside the fixed insertion hole. The plow blade has an arc-shaped structure, and the diameter of the through hole at one end of the plow blade is the same as that of the movable hole. When the plow blade needs to be connected and fixed to the positioning plate, the through hole and the movable hole can be aligned. Then, a fixing bolt is used to fix it through the through hole and the movable hole, so that the plow blades are distributed in a ring array on the outside of the positioning plate. This makes it easy to adjust the spacing between adjacent plow blades and facilitates the removal, installation, and maintenance of the plow blades.

[0024] 2. The protective cover has a semi-circular structure. After the protective cover is adjusted to the required angle, the sleeve and the fixed rod can be locked and fixed with bolts to prevent people around from being accidentally injured by the plow blade. The surface of the fixed socket is equipped with a dustproof film. When the locking screw is not inserted into the fixed socket, the dustproof film will unfold into a flat shape through its own elastic potential energy to block the fixed socket from dust and improve the protective effect.

[0030] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0031] See attached document Figure 1-4 This utility model provides an agricultural tillage machine, including a fixed frame 1 and a connecting arm 2. The connecting arm 2 is hinged to the upper end of the fixed frame 1. The end of the connecting arm 2 away from the fixed frame 1 is connected to the front or rear of the vehicle. The connection is fixed by multiple bolts, which facilitates the displacement of the entire fixed frame 1 by the connecting arm 2 when the vehicle starts. Side plates 3 are symmetrically installed on both sides of the fixed frame 1. A drive shaft 4 is rotatably connected in the middle of the side plates 3. A drive motor 31 is installed on one side of the outer end of the side plates 3. A bearing 32 is provided on the inner wall of one side of the drive motor 31. Both ends of the drive shaft 4 are rotatably connected to the bearing 32. The output shaft of one end of the drive motor 31 is connected to one end of the drive shaft 4 through the side plates 3 and the bearing 32. When the drive motor 31 starts, it can drive the drive shaft 4 to rotate. Positioning components 5 are installed at intervals on the outside of the drive shaft 4. Plow blades 6 are installed at intervals on the surface of the positioning components 5. When the drive shaft 4 rotates, the positioning components 5 can drive the plow blades 6 to rotate, which facilitates the use of the plow blades 6 to turn over the soil.

[0032] A fixing rod 11 is installed at the front end of the fixing frame 1. A sleeve 12 is movably fitted on the outside of the fixing rod 11. A protective cover 13 is fixedly welded to the outside of the sleeve 12. The protective cover 13 has a semi-circular structure. The protective cover 13 is fitted on the outside of the fixing rod 11 through the sleeve 12, which makes it easy to rotate and adjust the protective cover 13. When the protective cover 13 is adjusted to the required angle, the sleeve 12 and the fixing rod 11 are locked and fixed with bolts on both sides to prevent people around from being accidentally injured by the plow blade 6.

[0033] The drive shaft 4 has fixed insertion holes 41 spaced apart on its surface (the inner wall of the fixed insertion holes 41 can be provided with internal threads). The surface of the fixed insertion holes 41 is provided with a dustproof film 42. The dustproof film 42 has a cross-shaped cut in the middle. After the cross-shaped cut, the dustproof film 42 has a four-fan-shaped structure. The dustproof film 42 is made of rubber material. When no workpiece is inserted into the fixed insertion hole 41, the dustproof film 42 will unfold into a flat shape to block the fixed insertion hole 41 from dust through its own elastic potential energy. When a workpiece is inserted into the fixed insertion hole 41, the dustproof film 42 will automatically fold downwards without affecting the insertion of the workpiece.

[0034] Positioning assembly 5 includes a positioning disk 51 and a movable hole 52 on the surface of the positioning disk 51. A central hole 53 is formed in the center of the movable hole 52. The positioning disk 51 is fitted onto the outer end of the drive shaft 4 through the central hole 53. Lugs 54 are symmetrically welded to both sides of the positioning disk 51. The positioning disk 51 consists of two semi-circular structures, aligned and connected. A hole is formed in the center of the lugs 54 to facilitate screw penetration and locking. At this time, both the positioning disk 51 and the central hole 53 are circular structures. When it is necessary to adjust the spacing between adjacent plow blades 6, the positioning disk 51 can be moved horizontally outside the drive shaft 4. Threaded holes 511 are formed in the center of both ends of the positioning disk 51. The fixing insertion hole 41 has the same diameter as the threaded hole 511. The internal thread of 511 is connected to a locking screw 512, and one end of the locking screw 512 is provided with a handle. When the fixed insertion hole 41 is aligned with the threaded hole 511, the locking screw 512 is inserted through the threaded hole 511 and fixed inside the fixed insertion hole 41 (the distance between adjacent fixed insertion holes 41 is 5cm). The plow blade 6 has an arc-shaped structure and a through hole is opened at one end of the plow blade 6. The diameter of the through hole is the same as that of the movable hole 52. When the plow blade 6 needs to be connected and fixed to the positioning plate 51, the through hole can be aligned with the movable hole 52. A fixing bolt 61 is connected inside the through hole. Finally, the fixing bolt 61 can be used to fix the plow blade 6 through the through hole and the movable hole 52, which facilitates the removal, installation and maintenance of the plow blade 6.

[0035] The usage process of this utility model is as follows: When installing the positioning plate 51, the two semi-arc structures are assembled together so that the positioning plate 51 and the center hole 53 form a circular structure surrounding the drive shaft 4. Then, according to the soil zone specifications, the distance between the two adjacent positioning plates 51 is adjusted so that the positioning plate 51 moves horizontally outside the drive shaft 4. When the positioning plate 51 moves to the required position, the fixing hole 41 is aligned with the threaded hole 511. Then, the locking screw 512 is inserted through the threaded hole 511 and fixed inside the fixing hole 41. Finally, the through hole on one side of the plow blade 6 is aligned with the movable hole 52. Then, the fixing bolt 61 is inserted through the through hole and the movable hole 52 to fix the plow blade 6. When the drive motor 31 is started, it can drive the drive shaft 4 to rotate. When the drive shaft 4 rotates, the positioning component 5 can drive the plow blade 6 to rotate, making it convenient to use the plow blade 6 to turn over the soil.
