Description

Technical Field

[0001] This utility model relates to the technical field of agricultural machinery, and in particular to a horizontally suspended pressure film guide cylinder for a mulching machine. Background Technology

[0002] Covering farmland with plastic film is a very arduous and strenuous task. It typically requires two people to stretch the film from both sides, one person to back up while unfolding it, and another to collect soil from under the film and press it down at the edges. Except for the person pressing the edges, who can stand, the other three people must work bent over or even squatting. The work is physically demanding and inefficient, especially during strong winds when it's impossible to work. Currently, most agricultural mulching machines use a single, integrated soil-guiding cylinder with a film-pressing ring, as shown in the instruction manual. Figure 1 The soil guide cylinder shown has a main shaft in the middle, which is installed on the mulching machine. However, the shaft is located in the center of the soil guide cylinder during operation, resulting in a complex internal structure and limited space, causing unstable soil output and easy clogging. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a horizontally suspended pressure film guide cylinder for a mulching machine that has a simple structure, stable soil discharge, and controllable soil discharge volume.

[0004] This utility model discloses a horizontally suspended pressure film guide cylinder for a mulching machine, comprising a crossbeam, a longitudinal beam, a suspension mechanism, two side soil covering components, and a middle indirect soil covering component. The crossbeam is installed on the mulching machine, the longitudinal beam is installed in the middle of the crossbeam, and the suspension mechanism is installed at the bottom right side of the longitudinal beam. The two side soil covering components are installed on the suspension mechanism, and the middle indirect soil covering component is also installed on the suspension mechanism. The suspension mechanism connects and installs the two side soil covering components or the middle indirect soil covering component. The two side soil covering components can cover soil on both sides of the mulch film, and the amount of soil discharged can be controlled. In addition, the middle indirect soil covering component can cover soil at intervals in the middle of the mulch film, which can be selected by the user.

[0005] Preferably, the suspension mechanism includes a vertical beam, a rotating shaft, and two bearings. The vertical beam is bolted to the bottom of the longitudinal beam at the end away from the transverse beam, and the rotating shaft is rotatably mounted on the lower part of the vertical beam via the two bearings. The equipment is supported by the vertical beam and the rotating shaft, and the rotating shaft can rotate at the lower end of the vertical beam via the bearings, resulting in a simple structure.

[0006] Preferably, the soil covering assembly includes two soil guide cylinders, two pressure rings, multiple sets of soil guide plates, and adjustment components. The soil guide cylinders are equipped with adjustment components. The two soil guide cylinders are located at the front and rear ends of the rotating shaft. Pressure rings are installed on the outer side of the soil guide cylinders. Multiple sets of soil guide plates are installed on the inner wall of the soil guide cylinders. The soil guide plates are inclined. When the soil guide cylinders rotate, the soil is guided by the multiple sets of soil guide plates to cover the soil on both sides of the mulch film.

[0007] Preferably, the adjusting component includes two connecting discs, multiple adjusting plates, and multiple fixing screws. The two connecting discs are installed at the front and rear ends of the rotating shaft. Multiple adjusting plates are axially and evenly installed on the outer wall of the connecting discs. Adjusting grooves are opened on the soil guide cylinder at positions corresponding to the adjusting plates. The fixing screws are installed on the adjusting plates. Loosening the fixing screws allows the soil guide cylinder to slide on the adjusting plates, making the space between the connecting discs and the soil guide cylinder hollow, which facilitates soil leakage and allows control over the amount of soil discharged.

[0008] Preferably, the intermediate indirect soil covering assembly includes two intermediate soil guide cylinders, an adjusting cylinder, multiple adjusting screws, two second soil guide cylinders, two sets of second soil guide plates, and a fixing and adjusting device. The two intermediate soil guide cylinders are installed at the front and rear ends of the rotating shaft. An indirect soil leakage port is opened on the inner side of the intermediate soil guide cylinder. Multiple adjusting screws are installed on the outer side of the intermediate soil guide cylinder. The adjusting cylinder has a second adjusting groove and is fitted onto the outer wall of the intermediate soil guide cylinder. The second soil guide cylinder is installed on the inner wall of the intermediate soil guide cylinder through the fixing and adjusting device. A second sliding adjusting cylinder is set on the outer ring of the second soil guide cylinder. The space between the adjusting cylinder and the second soil guide cylinder is hollow. A second pressure film ring is set on the outer side of the second soil guide cylinder. Multiple second soil guide plates are installed in the inner walls of the second soil guide cylinder and the intermediate soil guide cylinder. When the intermediate soil guide cylinder rotates, it can cover the middle interval of the mulch film with soil. At the same time, the second soil guide cylinder covers the two sides of the mulch film with soil. Loosening the adjusting screws allows the adjusting cylinder to slide on the intermediate soil guide cylinder. The hollow space between the adjusting cylinder and the second soil guide cylinder facilitates soil leakage and allows control over the amount of soil discharged.

[0009] Preferably, the fixing and adjusting device includes multiple adjusting sleeves, multiple connecting rods, and multiple sets of locking bolts. Multiple adjusting sleeves are axially and evenly installed on the inner walls of the intermediate soil guide cylinder and the second soil guide cylinder. Multiple locking bolts are screwed onto the adjusting sleeves. The front and rear ends of the connecting rods are respectively inserted into the adjusting sleeves. The intermediate soil guide cylinder and the second soil guide cylinder are connected by adjusting sleeves and connecting rods. The connecting rods are fixed by tightening the locking bolts. The structure is simple and convenient to use.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the suspension mechanism connects and installs the soil covering components on both sides or the indirect soil covering components in the middle. The soil covering components on both sides can cover the soil on both sides of the mulch film and can control the amount of soil discharged.

Loosening the fixing screw 11 pulls the soil guide cylinder 6 to slide on the adjusting plate 10, so that the connecting plate 9 and the soil guide cylinder 6 are hollow, which facilitates soil leakage and can control the amount of soil discharged.

[0021] Example 2

[0022] like Figure 4 and Figure 5As shown, based on embodiment 1, two intermediate soil guide cylinders 12 are installed at the front and rear ends of the rotating shaft 4. An indirect soil leakage port is opened on the inner side of the intermediate soil guide cylinder 12. Multiple adjusting screws 14 are installed on the outer side of the intermediate soil guide cylinder 12. A second adjusting groove is opened on the adjusting cylinder 13.

When the intermediate soil guide cylinder 12 rotates, it can cover the middle interval of the mulch film with soil. At the same time, the second soil guide cylinder 15 covers the two sides of the mulch film with soil. Loosening adjusting screw 14 allows adjusting cylinder 13 to slide on intermediate soil guide cylinder 12. The adjusting cylinder 13 and the second soil guide cylinder 15 are hollow, which facilitates soil leakage and can control the amount of soil discharged.

[0024] like Figures 1 to 5 As shown, the mulching machine of this utility model uses a horizontally suspended soil guide cylinder. During operation, the crossbeam 1 is installed on the mulching machine, and the longitudinal beam 2 is installed in the middle of the crossbeam 1. The equipment is supported by the vertical beam 3 and the rotating shaft 4. The rotating shaft 4 can rotate at the lower end of the vertical beam 3 via bearings 5. When the soil guide cylinder 6 rotates, it guides the soil through multiple sets of guide plates 8, covering both sides of the mulch film with soil. Loosening the fixing screws 11 allows the soil guide cylinder 6 to slide on the adjusting plate 10, making the space between the connecting plate 9 and the soil guide cylinder 6 hollow, facilitating soil leakage. The amount of soil removed is controlled. In addition, the intermediate soil guide cylinder 12 and the second soil guide cylinder 15 are connected by the adjusting sleeve 17 and the connecting rod 18. The connecting rod 18 is fixed by tightening the locking bolt 19. When the intermediate soil guide cylinder 12 rotates, it can cover the middle interval of the mulch film with soil. At the same time, the second soil guide cylinder 15 covers the two sides of the mulch film with soil. Loosening the adjusting screw 14 allows the adjusting cylinder 13 to slide on the intermediate soil guide cylinder 12. The adjusting cylinder 13 and the second soil guide cylinder 15 are hollow, which facilitates soil leakage. This can be selected according to the user's needs.

[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
