Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a straw pushing mechanism for no-till machines. Background Technology

[0002] Straw is a general term for the stems, leaves, and ears of mature crops. It usually refers to the plant remains left after the harvest of crops such as wheat, rice, corn, potatoes, oilseeds, cotton, and sugarcane. Whether it is burned, discarded, or recycled for use as fuel or animal feed, a straw-pushing mechanism is needed to collect the straw for subsequent processing.

[0003] However, most of the existing straw-pushing mechanisms for no-till machines on the market currently use multiple bolts and nuts to fix the rake wheel used to gather straw together, which makes it inconvenient for workers to disassemble and assemble the rake wheel, making it difficult for workers to remove the rake wheel for inspection and maintenance, which is quite inconvenient.

[0004] Therefore, those skilled in the art have provided a straw pushing mechanism for no-till machines to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a straw pushing mechanism for no-till machines. The mechanism uses a threaded sleeve in the connecting mechanism to be threadedly connected to the rotating rod, and a cotter pin is inserted into the insert rod and the rotating rod to prevent the threaded sleeve from rotating, thus restricting the rake wheel on the rotating rod. This makes it convenient for workers to disassemble and assemble the rake wheel for inspection and maintenance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A straw pushing mechanism for a no-till machine includes a base and a folding mechanism. The folding mechanism includes two hydraulic rods and two mounting frames. A fixing block is fixedly connected to the middle of the upper end of the base. A rotating arm is hinged to the side of each hydraulic rod away from the center of the base. The inner wall of each rotating arm is fixedly connected to the mounting frame. A connecting mechanism is provided on both sides of the base. The connecting mechanism includes multiple hay rakes, multiple threaded sleeves, and multiple cotter pins. The front and rear ends of the outer wall of the mounting bracket away from the center of the base are hinged to rotating rods. The front ends of the outer walls of the rotating rods away from the center of the base are provided with slots. The inner walls of the threaded sleeves are threaded to the rotating rods. The side of the threaded sleeves near the center of the base is fixedly connected to an insert rod. The outer wall of the insert rod and the front end of the upper end of the rotating rod are provided with through slots. The above technical solution involves connecting a threaded sleeve to a rotating rod via a threaded connection, and using a cotter pin inserted into the rod and rotating rod to prevent the threaded sleeve from rotating, thus fixing the hay rake to the rotating rod. Once the cotter pin is removed, the threaded sleeve can be rotated and unscrewed from the rotating rod, making it convenient for workers to assemble and disassemble the hay rake.

[0007] Furthermore, support legs are fixedly connected to both sides of the lower end of the base, and a walking wheel is rotatably connected to the lower end of the outer wall of the support leg on the side away from the center of the base. The above technical solution allows the entire mechanism to be supported by two support legs fixedly connected to the bottom of the base, raising it a certain distance off the ground to prevent collision between the ground and the base. The rotating wheels connected to the support legs allow the entire mechanism to move along the ground under the action of external pulling force.

[0008] Furthermore, a traction frame is fixedly connected to the middle of the outer wall of the rear end of the base, all the hay rakes are rotatably connected to the rotating rod, and the upper end of the outer wall of the threaded sleeve is provided with a screwing groove. Through the above technical solution, the traction frame fixedly connected to the base, along with multiple bolts and nuts, can be connected to traction machinery, such as a tractor, enabling the entire mechanism to move on the ground. The rotational connection between the rake wheel and the rotating rod allows the rake wheel to be passively rotated when the entire mechanism moves forward, which can roll up the straw on the ground and concentrate it in the middle position. In addition, the screwing groove opened on the threaded sleeve allows the worker to use a hex wrench to insert into the screwing groove, rotate the threaded sleeve, and unscrew it from the rotating rod.

[0009] Furthermore, the inner walls of the front and rear ends of the fixing block are hinged to the hydraulic rods, and the inner walls of the front and rear ends of the base are hinged to the rotating arm. The above technical solution involves hinged hydraulic rods connected to the fixed block and rotating arm, allowing the rotating arm to rotate on the base under the action of the hydraulic rods, thus folding the mounting frame and its components above the base for easy transport.

[0010] Furthermore, all the insert rods are slidably connected to the slots, and the lower ends of the cotter pins all pass through the through slots and are engaged with the rotating rod and the insert rods; By using the above technical solution, the threaded sleeve can be prevented from rotating under vibration by inserting the fixedly connected insert rod into the slot on the rotating rod, and the cotter pin can be inserted into the through groove opened on the insert rod and the rotating rod. This prevents the threaded sleeve from falling off the rotating rod.

[0011] Furthermore, a fixing rod is fixedly connected to both the front and rear ends of the upper end of the mounting bracket, and a telescopic cylinder is hinged to the upper end of each fixing rod. A return spring is fixedly connected to the inner wall of the rear end of each telescopic cylinder. The above technical solution provides a fixed point for the installation of the telescopic cylinder by means of a fixed rod that is fixedly connected to the mounting frame, while a return spring fixedly connected inside the telescopic cylinder can act on the telescopic rod to compensate for its movement inside the telescopic cylinder.

[0012] Furthermore, each of the return springs is fixedly connected to a telescopic rod at its front end, and the front end of each telescopic rod passes through the telescopic cylinder and is hinged to the rotating rod. Through the above technical solution, the telescopic rod moves inside the telescopic cylinder, and the return spring can keep the telescopic rod in the extended state, thereby allowing the telescopic rod to apply a certain force to the rotating rod, so that the rotating rod drives the hay rake to keep it in contact with the ground.

[0013] This utility model has the following beneficial effects: This utility model proposes a straw pushing mechanism for a no-till machine. A threaded sleeve in the connecting mechanism is threadedly connected to a rotating rod. A cotter pin is inserted into the insert rod and the rotating rod to prevent the threaded sleeve from rotating, thus fixing the rake wheel on the rotating rod. By removing the cotter pin, the threaded sleeve can be rotated and unscrewed from the rotating rod, which facilitates the disassembly and assembly of the rake wheel for maintenance.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Reference Figure 1-5 This utility model provides a specific implementation method: A straw pushing mechanism for a no-till machine includes a base 1 and a folding mechanism 5. The folding mechanism 5 includes two hydraulic rods 502 and two mounting brackets 504. A fixing block 501 is fixedly connected to the middle of the upper end of the base 1. A rotating arm 503 is hinged to the side of the hydraulic rods 502 away from the center of the base 1. The inner wall of the rotating arm 503 is fixedly connected to the mounting bracket 504. A connecting mechanism 6 is provided on both sides of the base 1. The connecting mechanism 6 includes multiple hay rakes 603, multiple threaded sleeves 604, and multiple cotter pins 607. The front and rear ends of the outer wall of the mounting bracket 504 away from the center of the base 1 are hinged to a rotating rod 601. The front end of the outer wall of the rotating rod 601 away from the center of the base 1 is provided with a slot 602. The inner wall of the threaded sleeve 604 is threaded to the rotating rod 601. The side of the threaded sleeve 604 near the center of the base 1 is fixedly connected to an insert rod 605. The outer wall of the insert rod 605 and the front end of the upper end of the rotating rod 601 are provided with through grooves 606.

[0018] The threaded sleeve 604 in the connecting mechanism 6 is threadedly connected to the rotating rod 601, and the cotter pin 607 is inserted into the insert rod 605 and the rotating rod 601 to prevent the threaded sleeve 604 from rotating, so that the hay rake 603 is fixed on the rotating rod 601. When the cotter pin 607 is removed, the threaded sleeve 604 can be rotated and unscrewed from the rotating rod 601, which makes it convenient for workers to disassemble and install the hay rake 603 for inspection and maintenance.

[0019] Support legs 2 are fixedly connected to both sides of the lower end of the base 1. A traveling wheel 3 is rotatably connected to the lower end of the outer wall of the support legs 2 on the side furthest from the center of the base 1. The two support legs 2 fixedly connected to the lower part of the base 1 support the entire mechanism, raising it a certain distance from the ground to prevent collision between the ground and the base 1. The traveling wheel 3 rotatably connected to the support legs 2 allows the entire mechanism to move along the ground under external pulling force. A traction frame 4 is fixedly connected to the middle of the outer wall at the rear end of the base 1. Hay-raking wheels 603 are rotatably connected to the rotating rod 601. A turning groove 7 is provided on the upper end of the outer wall of the threaded sleeve 604. The traction frame 4 fixedly connected to the base 1, along with multiple bolts and nuts, can be connected to traction machinery, such as a tractor, enabling the entire mechanism to move. The mechanism is capable of moving on the ground. The rotational connection between the rake wheel 603 and the rotating rod 601 allows the rake wheel 603 to passively rotate as the entire mechanism moves forward, gathering straw from the ground and concentrating it in the center. Furthermore, the screwing groove 7 on the threaded sleeve 604 allows workers to use a hex wrench to insert into the groove 7 and rotate the threaded sleeve 604 to unscrew it from the rotating rod 601. The inner walls of the front and rear ends of the fixing block 501 are hinged to the hydraulic rod 502, and the inner walls of the front and rear ends of the base 1 are hinged to the rotating arm 503. By hinged to the hydraulic rod 502 connected to the fixing block 501 and the rotating arm 503, the rotating arm 503 can move under the action of the hydraulic rod 502. The mounting bracket 504 and its components can rotate on the base 1, folding them over the base 1 for easy transport. All insert rods 605 are slidably connected to slots 602. The lower ends of cotter pins 607 penetrate through slots 606 and engage with rotating rods 601 and insert rods 605. By inserting the insert rods 605 fixedly connected to the threaded sleeve 604 into slots 602 on the rotating rod 601, and with the cotter pins 607 inserted into the through slots 606 on the insert rods 605 and rotating rods 601, the threaded sleeve 604 can be prevented from rotating under vibration, thus preventing it from falling off the rotating rod 601. The front and rear ends of the upper part of the mounting bracket 504 are fixedly connected to fixing rods 8, and the upper ends of the fixing rods 8 are hinged to telescopic cylinders 9. Each telescopic cylinder 9 has a return spring 10 fixedly connected to the inner wall of its rear end. The fixed rod 8 fixedly connected to the mounting bracket 504 can provide a fixed point for the installation of the telescopic cylinder 9. The return spring 10 fixedly connected inside the telescopic cylinder 9 can act on the telescopic rod 11 to compensate for its movement inside the telescopic cylinder 9. The front end of each return spring 10 is fixedly connected to the telescopic rod 11. The front end of each telescopic rod 11 passes through the telescopic cylinder 9 and is hinged to the rotating rod 601. The telescopic rod 11 moves inside the telescopic cylinder 9, and the return spring 10 can keep the telescopic rod 11 in the extended state. This allows the telescopic rod 11 to apply a certain force to the rotating rod 601, so that the rotating rod 601 drives the hay rake 603 to keep it in contact with the ground.

[0020] Working principle: When using the straw pushing mechanism for no-till machines, the operator first uses multiple bolts and nuts with the traction frame 4 to install the entire mechanism onto the traction machine. Then, the hydraulic rod 502 is used to apply force to the rotating arm 503, unfolding the mounting frame 504 and its components. Next, the operator starts the traction machine, allowing the entire mechanism to move on the ground using the traveling wheels 3. With the help of the return spring 10 acting on the telescopic rod 11, the rotating rod 601 presses the rake wheel 603 against the ground, rolling up and gathering the straw. Finally, the operator can remove the cotter pin 607 from the through groove 606. Then, using a hex wrench inserted into the turning groove 7, the threaded sleeve 604 is rotated to remove the threaded sleeve 604 from the rotating rod 601. The rake wheel 603 can then be removed for maintenance, repair, or replacement.
