Description

Technical Field

[0001] This utility model relates to the field of planting mulching technology, specifically a mulching machine for garlic planting. Background Technology

[0002] Garlic is a vegetable with rich nutritional and medicinal value. The technology of mulching garlic cultivation has been used for many years. Originally, it was mostly used for mulching on flat land, which greatly helped to increase yield and improve quality, achieving good results. Mulching can reduce the heat dissipation of the soil, reduce the temperature difference between day and night, create a more stable temperature environment for garlic growth, which is conducive to the rooting and sprouting of garlic and safe overwintering. It also prevents water evaporation, improves the soil environment, increases fertilizer utilization, inhibits weed growth, and promotes the growth and development of garlic. The temperature effect of mulching can advance the bolting and maturity period of garlic, thereby achieving early maturity and high yield.

[0003] Currently, most garlic mulching machines have a frame structure. The mulch rolls are installed inside the frame of the mulching machine, and compaction and soil turning structures are installed on both sides to achieve simultaneous mulching and compaction. However, the mulch rolls are installed inside or at the bottom, making it very inconvenient to replace them with new rolls when they are used up. In addition, different plot sizes require different widths of mulch rolls, while the frame structure has relatively fixed dimensions and poor adaptability. Based on this, we propose a garlic mulching machine to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mulching machine for garlic cultivation, which facilitates the installation and replacement of the mulch rolls. It also features a more compact structure and better overall flexibility, solving the problems of existing mulching machines for garlic cultivation where the mulch roll installation position is located on the inside or bottom, making it inconvenient to replace the mulch roll when it is used up. Furthermore, the machines have relatively fixed dimensions and poor adaptability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mulching machine for garlic planting, comprising a frame and wheels mounted on the lower end of the frame. A pusher is mounted on one side of the frame, and mounting plates are provided on both sides of the frame. A clamping assembly is rotatably mounted on the upper end of the mounting plates, and a guide roller is rotatably mounted on the lower end of the opposite side of the mounting plates. The two mounting plates and the frame are movably connected by an adjusting assembly, which is used to drive the two mounting plates closer or further apart. When the two mounting plates are close together, the clamping assembly clamps the mulch film. An intermediate frame is mounted on the other side of the frame, and pressure rollers are rotatably mounted on both sides of the lower end of the intermediate frame. A compaction assembly is provided on the pressure rollers, which is used to press the edge of the mulch film into the soil.

[0006] Furthermore, the clamping assembly includes a connecting rod rotatably mounted on the top of the mounting plate and a conical clamping head fixedly connected to the connecting rod. The conical clamping head is located on opposite sides of the two mounting plates. When the two mounting plates approach each other until the conical clamping head is inserted into both ends of the mulch film, the mulch film is fixed.

[0007] Furthermore, the adjustment assembly includes a crossbar fixedly mounted on the frame. The crossbar has a hollow structure, and a double-threaded rod is rotatably connected to the inner side of the crossbar. A hand crank is fixedly connected to one end of the double-threaded rod, and movable blocks are threaded onto both ends of the double-threaded rod. When the hand crank is rotated, the double-threaded rod drives the two movable blocks to move closer or further apart.

[0008] Furthermore, a groove is provided on the crossbar, and a connecting block is slidably installed in the groove. The mounting plate and the moving block are fixedly connected by the connecting block. When the double-ended threaded rod rotates, it drives the two moving blocks to move closer to each other or separate.

[0009] Furthermore, a mounting shaft is rotatably connected to the mounting plate. A conveyor roller is mounted on one end of the mounting shaft, which is positioned below the guide roller. A drive wheel is mounted on the other end of the mounting shaft. When the drive wheel rolls on the ground, it drives the conveyor roller to rotate.

[0010] Furthermore, the front end of the frame is provided with a telescopic groove, the upper end of the intermediate frame is slidably connected to the telescopic groove, and a compression spring is provided in the telescopic groove. The upper and lower ends of the compression spring are fixedly connected to the frame and the intermediate frame, respectively.

[0011] Furthermore, the compaction assembly includes a compaction disc that is slidably mounted on the surface of the pressure roller. Blades are provided on both sides of the surface of the compaction disc. A positioning block is fixedly installed on the inner side of the compaction disc, and a positioning groove is opened on the surface of the pressure roller. The positioning block is slidably locked in the inner side of the corresponding positioning groove.

[0012] Furthermore, the positioning block has mounting holes for installing locking bolts, and the positioning block is fixed to the pressure roller by the locking bolts.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] This garlic mulching machine uses a clamping assembly at the top to hold and fix both ends of the mulch film, optimizing the installation position of the film. When changing the film, there is no need to lift the frame, making the installation and replacement of the film more time-saving and labor-saving. At the same time, a conveyor roller is added, which is connected to the power wheel. When the frame moves, the power wheel contacts the ground and rotates, thereby driving the synchronous rotation of the conveyor roller to convey the mulch film. This ensures that the conveying speed of the mulch film is consistent with the forward speed of the mulching machine, preventing the mulch film from wrinkling or tearing. After laying, the compaction assembly is used to press the edges of the mulch film directly into the soil layer, making the mulch film adhere better. Attached Figure Description

[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.

[0024] Please see Figures 1-6This embodiment of a garlic mulching machine includes a frame 1 and wheels 2 mounted on the lower end of the frame 1. A push frame 3 is mounted on one side of the frame 1, and mounting plates 4 are provided on both sides of the frame 1. A clamping assembly is rotatably mounted on the upper end of the mounting plates 4, and a guide roller 5 is rotatably mounted on the lower end of the opposite side of the mounting plates 4. The two mounting plates 4 and the frame 1 are movably connected by an adjusting assembly, which is used to drive the two mounting plates 4 closer or further apart. When the two mounting plates 4 are close together, the clamping assembly clamps the mulch film. An intermediate frame 6 is mounted on the other side of the frame 1, and pressure rollers 7 are rotatably mounted on both sides of the lower end of the intermediate frame 6. A compaction assembly is provided on the pressure rollers 7, which is used to press the edge of the mulch film into the soil layer.

[0025] In this embodiment, the clamping assembly includes a connecting rod 41 rotatably mounted on the top of the mounting plate 4 and a conical clamping head 42 fixedly connected to the connecting rod 41. The conical clamping head 42 is disposed on opposite sides of the two mounting plates 4. When the two mounting plates 4 approach each other until the conical clamping head 42 is inserted into both ends of the mulch film roll, the mulch film roll is fixed.

[0026] It should be noted that personnel move the frame 1 by pulling the push rod 3. The moving wheel 3 and the pressure roller 7 facilitate movement. The mulch film is installed between the two mounting plates 4 through the clamping assembly. One end of the mulch film is connected to the ground through the guide roller 5. When moving, the mulch film is covered on the ground to achieve film covering.

[0027] Please see Figure 1 , Figure 3 and Figure 4 In this embodiment, the adjustment component includes a crossbar 11 fixedly installed on the frame 1. The crossbar 11 has a hollow structure. A double-threaded rod 12 is rotatably connected to the inner side of the crossbar 11. A hand crank 13 is fixedly connected to one end of the double-threaded rod 12. Moving blocks 14 are threadedly installed at both ends of the double-threaded rod 12. When the hand crank 13 is rotated, the double-threaded rod 12 drives the two moving blocks 14 to move closer or further away.

[0028] In this embodiment, the threads at both ends of the double-threaded rod 12 are in opposite directions (left-handed thread on the left and right-handed thread on the right). Therefore, when the hand crank 13 is rotated, the two moving blocks 14 can move synchronously in opposite directions along the crossbar 11, realizing stepless adjustment of the spacing between the installation uprights 4, which is suitable for mulch film rolls with a width of 80 to 150 cm. The surface of the moving block 14 that contacts the inner wall of the crossbar 11 is provided with wear-resistant pads to extend its service life.

[0029] Please see Figure 1 , Figure 3 and Figure 5In this embodiment, a mounting shaft 52 is rotatably connected to the mounting plate 4. A conveying roller 51 is mounted on one end of the mounting shaft 52 and is positioned below the guide roller 5. A power wheel 53 is mounted on the other end of the mounting shaft 52. When the power wheel 53 rolls on the ground, it drives the conveying roller 51 to rotate. A telescopic groove 61 is provided at the front end of the frame 1. The upper end of the intermediate frame 6 is slidably connected to the telescopic groove 61. A compression spring 62 is provided in the telescopic groove 61. The upper and lower ends of the compression spring 62 are fixedly connected to the frame 1 and the intermediate frame 6, respectively.

[0030] It should be noted that the outer periphery of the power wheel 53 is wrapped with rubber material, which can improve the grip on the soil surface and prevent slippage. The surface of the conveying roller 51 adopts a grid pattern design to increase the friction with the mulch film, ensuring that the mulch film conveying speed is consistent with the forward speed of the mulching machine, and preventing the mulch film from wrinkling or tearing.

[0031] The spring constant of the compression spring 62 has been optimized (spring constant is 20N / mm) to ensure that the mulch film fits tightly to the ground. The sliding connection between the intermediate frame 6 and the telescopic groove 61 is provided with a grease filling port. Regularly adding grease can reduce wear.

[0032] Please see Figure 2 and Figure 5 , Figure 6 In this embodiment, the compaction assembly includes a compaction disc 71 that is slidably mounted on the surface of the pressure roller 7. Blades are provided on both sides of the surface of the compaction disc 71. A positioning block 72 is fixedly mounted on the inner side of the compaction disc 71. A positioning groove 73 is provided on the surface of the pressure roller 7. The positioning block 72 is slidably engaged in the inner side of the corresponding positioning groove 73. A mounting hole for installing a locking bolt is provided on the positioning block 72. The positioning block 72 is fixedly mounted on the pressure roller 7 by the locking bolt.

[0033] It should be noted that the blades on both sides of the compaction disc 71 are made of manganese steel with a cutting angle of 30°, which can easily cut into the soil to a depth of 5-8cm, burying the edge of the mulch film into the soil layer. The length of the positioning groove 73 is 1 / 3 of the total length of the pressure roller 7, which can adapt to the compaction requirements of mulch film edges of different widths, while preventing soil turning, simplifying the structure of the frame 1 and improving efficiency.

[0034] Please see Figure 7 Based on another embodiment of the compaction component in this embodiment, the compaction disc 71 is an inclined soil covering disc. When moving, it can turn up the soil layer at the edge of the mulch film and place it at the edge of the mulch film to form a soil covering and fixation on the edge of the mulch film.

[0035] The working principle of the above embodiments is as follows:

[0036] Align the inner cores at both ends of the plastic film roll with the two conical clamping heads 42, and fix the plastic film roll by adjusting the positions of the mounting plates 4 on both sides. During adjustment, rotate the hand crank 13 to drive the double-headed threaded rod 12 to rotate. Since the threads at both ends of the threaded rod turn in opposite directions, the two moving blocks 14 move synchronously in opposite directions along the crossbar 11. The distance between the mounting plates 4 changes through the connecting block 16 until it matches the current width of the plastic film. Then, fix the end of the plastic film to the ground through the guide roller 5. When personnel move the frame 1 through the push frame 3, the plastic film... When laid on the ground, the power wheel 53 contacts and rolls with the ground. The shaft 52 drives the conveyor roller 51 to rotate synchronously. The friction of the grid pattern on the surface of the conveyor roller 51 is used to release the mulch film from the roll at a uniform speed. The moving speed should not be too fast, and the uniform speed (1 to 1.5 m / s) should be maintained as much as possible. After the mulch film is laid on the ground, it is compacted by the pressure roller 7. When the pressure roller 7 rolls, the blade cuts into the soil 5 to 8 cm to bury the edge of the mulch film into the soil layer, thus completing the mulching and fixing. After the laying is completed, the unused roll is removed.

[0037] It should be noted that the compaction assembly achieves compaction through the weight of the frame 1 and the pressure roller 7. The blade needs to be inserted into the ground so that the pressure roller 7 can roll on the ground, thus it cannot be used on hard and compacted soil.

[0038] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
