Description

Technical Field

[0001] This utility model relates to a towing structure for agricultural machinery implements, belonging to the field of agricultural machinery. Background Technology

[0002] Ridging is a farming method that involves piling soil into long, raised ridges (ridges) and creating furrows between them. This method helps improve soil aeration, drainage, and water retention, while also facilitating crop root growth and mechanized operations. Two opposing plow blades are mounted on a plow frame, which is then attached to the rear of the agricultural machinery. As the machinery moves the plow frame, the two opposing plow blades create ridges on the ground. Currently, the distance between the two plow blades on the plow frame is fixed, making it impossible to adjust the ridge width according to the width of the plastic greenhouse. This can easily lead to situations where parts of the ground within the greenhouse cannot be properly ridged. Therefore, it is necessary to design a towing structure for agricultural machinery that can easily create ridges of varying widths on the ground. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a towing structure for agricultural machinery to solve the problems mentioned in the background art. This utility model realizes the adjustment of the plow blade spacing, which makes it easier to create ridges of different widths on the ground.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a towing structure for agricultural machinery includes a crossbeam. Two vertically arranged connecting plates are mounted on one end of the crossbeam. Two movable arms, symmetrically arranged about the crossbeam, are rotatably mounted between the two connecting plates. A first plow blade is mounted on the end of each movable arm away from the connecting plates. An extension arm is rotatably mounted on the end of each movable arm near the first plow blade. A slide is rotatably mounted between the two extension arms. The slide is fitted onto the crossbeam and slidably connected to it. A second plow blade is mounted on the end of the crossbeam away from the connecting plates. A sleeve is mounted on the upper surface of the crossbeam near the second plow blade. A stud is rotatably mounted inside the sleeve. Two mating brackets are provided on the upper surface of the slide. Semi-circular threaded grooves are machined on the opposite surfaces of the two brackets. One end of the stud is threaded into the space formed by the two threaded grooves. A handwheel is mounted on the end of the stud away from the brackets. The brackets are connected to the slide via positioning components.

[0005] Furthermore, the positioning component includes an L-shaped plate, and an L-shaped plate is installed on the end of each of the two card seats facing the connecting plate. A support plate is provided on the side of the L-shaped plate facing the connecting plate, which fits against the L-shaped plate. One end of the support plate is welded and fixed to the slide. The support plate is connected to the corresponding L-shaped plate by fasteners formed by screws and nuts.

[0006] Furthermore, a limiting plate for restricting the position of the nut is installed on the upper part of the side of the support plate opposite to the L-shaped plate. The limiting plate has an L-shaped structure, and one end of the screw passes through the L-shaped plate, the support plate and the limiting plate in sequence before being threaded to the nut.

[0007] Furthermore, an insert plate is installed on the upper surface of one of the card holders, and a card plate that cooperates with the insert plate is installed on the upper surface of the other card holder. The card plate has an L-shaped structure, and one end of the insert plate extends into the card plate. Multiple upper pin holes are opened on the upper surface of the card plate, and multiple lower pin holes that cooperate with the upper pin holes are opened on the upper surface of the insert plate. A positioning pin is inserted into the channel formed by the upper pin holes and the lower pin holes.

[0008] Furthermore, a U-shaped frame is installed on the arc-shaped portion of the second plow blade, and a support wheel is rotatably installed inside the U-shaped frame.

[0009] Furthermore, a lifting lug with a U-shaped structure is installed on the upper part of the outer surface of the sleeve.

[0010] Furthermore, a lug is welded to the end of the crossbeam away from the second plow blade, and the lug is located on the side of the connecting plate opposite to the card seat.

[0011] The beneficial effects of this utility model are:

[0012] 1. Use the handwheel to rotate the stud, which in turn drives the slide to move along the crossbeam through the two clamps. At this time, the angle between the movable arm and the extension arm changes, making the gap between the two first plow blades wider or narrower, thus adjusting the gap between the plow blades. This makes it easier to create ridges of different widths on the ground. The two first plow blades and the second plow blade work together to form two ridges in one go.

[0013] 2. Connect the two L-shaped plates to the two support plates on the slide block with screws and nuts respectively to complete the assembly of the two clamps and the slide block. When dirt enters between the two clamps and affects the rotation of the stud, the clamps and studs can be separated by removing the screws and nuts, making it easy to clean the dirt that has entered the thread groove.

[0014] 3. When installing screws and nuts, make one end of the screw pass through the L-shaped plate, the support plate and the limiting plate in sequence, and then tighten the nut. Under the restriction of the limiting plate, there is a gap between the nut and the support plate. When the nut and screw cannot be separated normally due to corrosion, the screw can be cut off by using the gap between the limiting plate and the support plate. This allows the card holder and the stud to be separated without damaging other parts. Attached Figure Description

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a towing structure for agricultural machinery, including a crossbeam 1, with a hanging ear 3 welded to the end of the crossbeam 1 away from the second plow blade 8. The hanging ear 3 is located on the side of the connecting plate 2 away from the card seat 16. Two vertically arranged connecting plates 2 are installed at one end of the crossbeam 1. Two movable arms 4 are rotatably installed between the two connecting plates 2 and are symmetrically arranged about the crossbeam 1. A first plow blade 6 is installed at the end of the movable arm 4 away from the connecting plate 2. An extension arm 5 is rotatably installed at the end of each of the two movable arms 4 near the first plow blade 6. A slide 7 is rotatably installed between the two extension arms 5. The slide 7 is sleeved on the crossbeam 1 and slidably connected to the crossbeam 1. A second plow blade 8 is installed at the end of the crossbeam 1 away from the connecting plate 2. A U-shaped frame 9 is installed on the arc-shaped part of the second plow blade 8. A support wheel 10 is rotatably installed inside the U-shaped frame 9. The structure formed by the U-shaped frame 9 and the support wheel 10 plays a supporting role and limits the depth of the second plow blade 8 inserted into the ground.

[0023] See Figure 1 and Figure 2A sleeve 12 is installed on the upper surface of the crossbeam 1 near the end of the second plow blade 8. A stud 13 is rotatably installed inside the sleeve 12. The upper surface of the slide 7 is provided with two mutually cooperating retaining seats 16. The opposing surfaces of the two retaining seats 16 are machined with semi-circular threaded grooves. One end of the stud 13 is threaded into the space formed by the two threaded grooves. A handwheel 11 is installed on the end of the stud 13 away from the retaining seat 16. By rotating the stud 13 with the handwheel 11, the stud 13 drives the slide 7 to move along the crossbeam 1 through the two retaining seats 16. At this time, the angle between the movable arm 4 and the extension arm 5 changes, so that the distance between the two first plow blades 6 becomes wider or narrower, realizing the adjustment of the plow blade distance, which is convenient for ridging the soil ridges of different widths on the ground. The two first plow blades 6 and the second plow blade 8 cooperate with each other to facilitate the formation of two soil ridges at one time. A U-shaped lifting lug is installed on the upper part of the outer surface of the sleeve 12. The lifting lug provides a lifting point for connecting with agricultural machinery.

[0024] See Figures 1-3 Each of the two card holders 16 has an L-shaped plate 20 installed on one end facing the connecting plate 2. The side of the L-shaped plate 20 facing the connecting plate 2 has a support plate 19 that fits against the L-shaped plate 20. One end of the support plate 19 is welded and fixed to the slide 7. The support plate 19 is connected to the corresponding L-shaped plate 20 by fasteners formed by screws 21 and nuts 18, so that the two L-shaped plates 20 are connected to the two support plates 19 on the slide 7 by screws 21 and nuts 18 respectively, thus completing the assembly of the two card holders 16 and the slide 7. When mud enters between the two card holders 16 and affects the rotation of the stud 13, the card holders 16 and the stud 13 can be separated by removing the screws 21 and nuts 18, so as to easily clean the mud that has entered the thread groove.

[0025] See Figures 1-4 A limiting plate 17 for limiting the position of the nut 18 is installed on the upper part of the side of the support plate 19 opposite to the L-shaped plate 20. The limiting plate 17 has an L-shaped structure. When installing the screw 21 and the nut 18, one end of the screw 21 passes through the L-shaped plate 20, the support plate 19 and the limiting plate 17 in sequence, and then the nut 18 is screwed on. Under the restriction of the limiting plate 17, there is a gap between the nut 18 and the support plate 19. When the nut 18 and the screw 21 cannot be separated normally due to corrosion, the screw 21 can be cut off by using the gap between the limiting plate 17 and the support plate 19, so as to separate the card holder 16 and the stud 13 without damaging other components.

[0026] See Figures 1-4One card holder 16 has an insert plate 22 mounted on its upper surface, and another card holder 16 has a card plate 15 mounted on its upper surface that mates with the insert plate 22. The card plate 15 has an L-shaped structure, with one end of the insert plate 22 extending into the card plate 15. The upper surface of the card plate 15 has multiple upper pin holes 23, and the upper surface of the insert plate 22 has multiple lower pin holes 24 that mate with the upper pin holes 23. A positioning pin 14 is inserted into the channel formed by the upper pin holes 23 and the lower pin holes 24 to improve the stability of the assembly between the two card holders 16.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
