Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a stubble cutter for a no-till planter. Background Technology

[0002] No-till seeding technology is becoming increasingly popular in modern agriculture. During no-till seeding, a stubble cutter is responsible for cutting crop residues on the soil surface to ensure smooth seeding. Stubble cutters typically contain high-speed rotating cutting components that, upon contact with the tough crop residues and soil, withstand significant friction and impact from the cutting components and their supporting structure.

[0003] Existing stubble cutters experience intense friction between the cutting components and the rotating shaft during prolonged high-speed operation. Traditional lubrication methods, such as periodic manual oiling or grease injection, often fail to guarantee continuous and sufficient lubrication, leaving the cutting components in a semi-dry friction state for extended periods. This inadequate lubrication accelerates wear on the cutting components, significantly shortening their lifespan and necessitating frequent replacement and maintenance. Frequent component replacement not only increases the economic burden on farmers but also consumes substantial time and effort, severely impacting the efficiency and continuity of agricultural machinery operations. Therefore, the problem of severe wear and frequent maintenance of the cutting components in existing stubble cutters due to a lack of continuous and effective lubrication has become a prominent issue restricting the operational efficiency and economy of no-till seeders.

[0004] Therefore, this utility model proposes a stubble cutter for a no-till planter to solve the problem of severe wear and frequent maintenance of the cutting parts of the stubble cutter in the prior art due to the lack of continuous and effective lubrication. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a stubble cutter for a no-till planter, aiming to improve the problems of severe wear and frequent maintenance of the cutting components in some existing no-till planter stubble cutters due to lack of continuous and effective lubrication, resulting in short service life and low operating efficiency.

[0006] This utility model provides a stubble cutter for a no-till planter, comprising: a mounting plate and a cutting component; and a lubrication mechanism.

[0007] The cutting element is located on one side of the mounting plate.

[0008] The lubrication mechanism includes a rotating shaft, an oil reservoir, a small hole, and a small ball. One end of the rotating shaft is fixedly connected to the outer side of the mounting plate, and the cutting element is rotatably connected to the surface of the rotating shaft, and the cutting element can rotate around the axis of the rotating shaft. An oil reservoir is formed inside the rotating shaft, and a small hole is formed on the side wall of the rotating shaft, the small hole connecting the oil reservoir to the outer surface of the rotating shaft. A small ball is slidably fitted inside the oil reservoir, and in its natural state, the small ball can abut against the end of the small hole located on the inner wall of the oil reservoir, sealing the small hole.

[0009] Furthermore, the mounting plate serves as the basic support for the mounting plate, the cutting component, and the lubrication mechanism. The rotating shaft of the lubrication mechanism is connected to the rotating component to achieve rotational support and lubrication supply for the cutting component, thus forming a fully functional slag cutter.

[0010] Preferably, the system further includes auxiliary components, which include a fixed shaft, a baffle, and screws. The fixed shaft is fixedly connected to the surface of the mounting plate, and one end of the baffle is rotatably connected to the fixed shaft. Through its rotatable connection with the fixed shaft, the baffle can rotate between a protective position that shields the cutting element and a working position that avoids the cutting element.

[0011] Preferably, the surface of the mounting plate has mounting holes, and the screw passes through the baffle and is threaded into the mounting holes, so that the baffle is fixed to the mounting holes by the screw.

[0012] Preferably, the lubrication mechanism further includes a feeding port, which is fixedly connected to the top of the end of the rotating shaft away from the mounting plate, and the feeding port is in communication with the oil storage cavity to replenish lubricating oil into the oil storage cavity through the feeding port.

[0013] Preferably, the diameter of the hole is smaller than the diameter of the ball, and the ball is a steel ball with a smooth and wear-resistant surface.

[0014] Preferably, the rotating shaft has a cylindrical structure, and the cutting component has a shaft hole at its center that is adapted to the rotating shaft. The outer wall of the rotating shaft and the inner wall of the shaft hole of the cutting component form a rotating mating surface, and the outlet of the small hole is located on the rotating mating surface.

[0015] Preferably, the length of the baffle is greater than the radius of the cutting element, and the size and shape of the baffle allow it to completely cover the blade portion of the cutting element when the baffle is in the protective position.

[0016] Preferably, the mounting plate has two mounting holes, which are located in the working position and the protective position of the baffle, respectively, for the screws to lock the baffle in different states.

[0017] Preferably, the mounting plate is further provided with fixing holes, which are used to fix the mounting plate to the crossbeam of the no-till planter by bolts.

[0018] This utility model has the following beneficial effects: 1. This utility model, by setting up a lubrication mechanism, utilizes the cooperation of the oil storage chamber, small hole and sliding ball inside the rotating shaft to achieve automatic lubrication when the cutting part rotates. It solves the problem of severe wear and frequent maintenance of the cutting parts of the existing slag cutter due to lack of continuous and effective lubrication, and achieves the technical effect of effectively reducing the wear of the cutting parts, extending the service life and reducing the maintenance frequency.

[0019] 2. This utility model, by setting auxiliary components, including a rotatable baffle and a screw locking structure, allows the baffle to switch between a protective position and a working position. This solves the safety hazard of exposed cutting parts in the non-working state of the existing slag cutter, which poses a risk of accidental injury to the operator. It achieves the technical effect of improving the safety of equipment operation and preventing accidental injury to personnel.

[0023] 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 described embodiments 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0024] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides a stubble cutter for a no-till planter, which aims to solve the problem of severe wear and frequent maintenance caused by the lack of effective continuous lubrication of the cutting components of the existing stubble cutter during long-term high-speed operation.

[0025] like Figure 1 As shown, it includes a mounting plate 1 and a cutting component 4 disposed on one side of the mounting plate 1; the mounting plate 1 serves as the mounting base for the entire device and connects to the main body of the no-till planter, while the cutting component 4 is used to achieve the function of cutting stubble; in order to provide continuous and effective lubrication for the cutting component 4, a lubrication mechanism 5 is also included, which is used to lubricate the cutting component 4, including a rotating shaft 51, an oil storage chamber 53, a small hole 52, and a small ball 54.

[0026] One end of the rotating shaft 51 is fixedly connected to the outside of the mounting plate 1. The cutting component 4 is rotatably connected to the surface of the rotating shaft 51, allowing the cutting component 4 to rotate freely around the axis of the rotating shaft 51, thereby achieving efficient slag cutting during operation. An oil storage chamber 53 is provided inside the rotating shaft 51 for storing lubricating oil. A small hole 52 is provided on the side wall of the rotating shaft 51, connecting the oil storage chamber 53 and the outer surface of the rotating shaft 51, serving as a channel for the outward delivery of lubricating oil. A small ball 54 is slidably fitted inside the oil storage chamber 53. In its natural state, the small ball 54 can abut against one end of the small hole 52 located on the inner wall of the oil storage chamber 53, thereby... This seals the small hole 52; this structure ensures that lubricating oil will not easily flow out of the small hole 52 when the cutting element 4 is not working, while when the cutting element 4 is rotating, the lubricating oil can be supplied automatically or intermittently; the fit between the ball 54 and the small hole 52 allows the supply of lubricating oil to be adjusted according to the operating state of the cutting element 4, effectively reducing the frequency of manual maintenance and significantly extending the service life of the cutting element 4; the rotating mating surface between the cutting element 4 and the rotating shaft 51 is the main working area of ​​the lubrication mechanism 5, and the outlet of the small hole 52 is precisely located on this mating surface, ensuring that the lubricating oil can directly act on the friction area.

[0027] Reference Figures 1 to 3 The auxiliary component 3 has a fixed shaft 31, a baffle 32, and a screw 33. The fixed shaft 31 is fixedly connected to the surface of the mounting plate 1. One end of the baffle 32 is rotatably connected to the fixed shaft 31, so that the baffle 32 can rotate around the fixed shaft 31. The surface of the mounting plate 1 is provided with a mounting hole 2. The screw 33 passes through the baffle 32 and is threaded into the mounting hole 2. Through the threaded connection between the screw 33 and the mounting hole 2, the baffle 32 can be fixed on the mounting plate 1.

[0028] When the cutter is working, the baffle 32 can be rotated to a position that avoids the working part 4 by rotating its connection with the fixed shaft 31. At this time, the screw 33 fixes the baffle 32 to the mounting hole 2, ensuring that the baffle 32 does not affect the normal operation of the cutting part 4. When the cutter is not working, the baffle 32 can be rotated to a protective position that blocks the cutting part 4, and is fixed to another mounting hole 2 by the screw 33, thereby effectively blocking the cutting part 4. This rotating locking auxiliary component 3 ensures the safety of the cutting part 4 in the non-working state and effectively prevents personnel from accidentally touching or bumping into the cutting part 4 and getting injured.

[0029] The auxiliary component 3 includes a fixed shaft 31, a baffle 32, and a screw 33. The fixed shaft 31 is fixedly connected to the surface of the mounting plate 1. One end of the baffle 32 is rotatably connected to the fixed shaft 31, so that the baffle 32 can rotate around the fixed shaft 31 and switch between a protective position that blocks the cutting part 4 and a working position that avoids the cutting part 4. The surface of the mounting plate 1 is provided with a mounting hole 2. The screw 33 passes through the baffle 32 and is threaded into the mounting hole 2, so that the baffle 32 is fixed to the mounting hole 2 by the screw 33, so that it remains stable in the designated position.

[0030] The lubrication mechanism 5 also includes a feeding port 55; the feeding port 55 is fixedly connected to the top of the end of the rotating shaft 51 away from the mounting plate 1, and the feeding port 55 is connected to the oil storage cavity 53. Lubricating oil can be directly added to the oil storage cavity 53 through the feeding port 55, simplifying maintenance operations. The diameter of the small hole 52 is smaller than the diameter of the small ball 54; the small ball 54 is preferably a steel ball, which has a smooth surface and good wear resistance, ensuring low friction loss when the lubricating oil flows, and can work reliably for a long time. The rotating shaft 51 has a cylindrical structure; the center of the cutting part 4 has a shaft hole that matches the rotating shaft 51, and the outer wall of the rotating shaft 51 and the inner wall of the shaft hole of the cutting part 4 form a rotating mating surface, and the outlet of the small hole 52 is precisely located here. On the rotating mating surface, the lubricating oil is directly delivered to the friction area. The length of the baffle 32 is greater than the radius of the cutting part 4. The size and shape design of the baffle 32 ensures that it can completely cover the blade of the cutting part 4 when the baffle 32 is in the protective position, eliminating the risk of accidental injury. Two mounting holes 2 are provided on the mounting plate 1. These two mounting holes 2 are located in the working position and the protective position of the baffle 32, respectively, and are used by the screw 33 to lock the baffle 32 in the working position or the protective position, thereby providing a stable positioning. The mounting plate 1 is also provided with fixing holes. The fixing holes are used to fix the mounting plate 1 to the crossbeam of the no-till seeder with bolts to ensure that the cutter will not loosen or fall off during high-speed operation.

[0031] The implementation principle of this application embodiment is as follows: When the no-till seeder starts working and the drive cutting component 4 starts to rotate, the cutting component 4, through its rotational cooperation with the rotating shaft 51, causes the internal structure of the lubrication mechanism 5 or the lubricating oil inside it to be subjected to centrifugal force; under the action of centrifugal force, the lubricating oil in the oil storage chamber 53 overcomes the resisting force of the small ball 54 and flows out of the small hole 52; the flowing lubricating oil directly enters the rotating mating surface between the rotating shaft 51 and the cutting component 4, providing continuous and uniform lubrication for the high-speed rotating cutting component 4; this adaptive lubrication method significantly reduces the friction and wear between the cutting component 4 and the rotating shaft 51, extends the service life of the components, avoids downtime due to insufficient lubrication, and effectively solves the problem of rapid wear and frequent maintenance of cutting components in the prior art; at the same time, lubricating oil can be conveniently replenished to the oil storage chamber 53 through the feeding port 55, further improving the convenience of maintenance.

[0032] When the no-till planter stops operating or requires maintenance, the operator can release the screw 33 from the mounting hole 2, rotate the baffle 32 in the auxiliary component 3 around the fixed shaft 31 to the protective position, so that it completely covers the blade of the cutting part 4, and then lock it back into the mounting hole 2 corresponding to the protective position by the screw 33. This design effectively prevents personnel from accidentally touching or bumping into the cutting part 4 when the equipment is not in operation, thus greatly improving the safety of equipment operation. When the equipment needs to work normally, the baffle 32 is rotated and locked in the working position to ensure that the cutting part 4 can rotate freely to cut the stubble.
