Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, and in particular to a soil clod crushing mechanism for a mulched soil compactor. Background Technology

[0002] A mulching and compaction machine is an agricultural machine that integrates mulching and compaction functions. It is mainly used for mulching operations in farmland. By smoothly covering the soil surface with mulch film and compacting the soil edges, it achieves effects such as heat preservation, moisture retention, weed suppression, and improved soil fertility, thereby promoting crop growth and increasing crop yield. A mulching and compaction machine typically consists of a power system, a walking mechanism, a mulching device, and a compaction device. During operation, the power system drives the walking mechanism to move the machine forward, and the mulching device unfolds the mulch film from the roll. The film is laid flat on the soil surface, and the soil compaction device compacts the soil on both sides of the film using rollers or plates to prevent the film from being blown away or shifted by the wind. However, in actual use, the soil clods on the land are large, which can easily cause the clods to lift or penetrate the film, thus affecting the effectiveness of the film. Existing film covering and soil compaction machines cannot crush the soil clods. Therefore, a soil clod crushing mechanism needs to be installed in front of the film covering device and the soil compaction device to crush the soil clods, thereby leveling the land and facilitating the subsequent soil compaction device to compact the soil. Utility Model Content

[0003] To overcome the technical defects of existing technologies, this utility model provides a soil clod crushing mechanism for a mulching and compaction machine. It has the advantage of good crushing effect. The soil-pulling component can move the soil clods on the ground to the lower end of the mounting frame, thereby completing the aggregation of soil clods and improving the crushing effect. At the same time, the crushing component can rotate under the drive of a servo motor, thereby crushing the soil clods by the breaker hammer, avoiding the soil clods being too large and affecting subsequent mulching and compaction. Furthermore, when not in use, the rotation radius of the breaker hammer can be shortened, making it convenient for users to store.

[0004] The technical solution adopted by this utility model is as follows: It includes an installation frame, with connectors fixedly installed at both ends of the frame for connection to an external mulching and compaction machine. U-shaped installation plates are fixedly installed on both sides of the lower end of the frame. A soil-moving component is installed between the installation plates, located on both sides of the lower outer end of the frame. A servo motor is fixedly installed on one side of the frame, and a rotating shaft is fixedly installed at the output end of the servo motor. The rotating shaft is rotatably engaged with the frame. A crushing component is fixedly arrayed on the rotating shaft and located inside the frame. In use, the structure is first connected to the external mulching and compaction machine via the connectors. During use, the soil-moving component moves soil clods to the lower end of the frame, thus accumulating the soil clods and improving crushing efficiency. When soil clods are moved to the lower end of the frame, the servo motor drives the rotating shaft and the crushing component to rotate, thereby crushing the soil clods and facilitating subsequent mulching and compaction.

[0005] Preferably, in order to drive the rotating roller to rotate, the soil-removing assembly includes a control motor, which is fixedly installed on the lower end of the outer side of the mounting plate, and the output end of the control motor is fixedly installed with a rotating roller, which is rotatably engaged inside the mounting plate.

[0006] Preferably, in order to drive the agitator plate and the rubber scraper to rotate, thereby moving the soil clods to the lower end of the mounting frame, the agitator plate is fixedly installed on the outer circumferential array of the rotating roller, and a rubber scraper is fixedly installed on one side of the agitator plate.

[0007] Preferably, in order to mount the crushing component array on the rotating shaft, the crushing component includes mounting blocks, and the mounting block array is fixedly mounted on the rotating shaft.

[0008] Preferably, in order to install the fixing cylinder on the outside of the mounting block, fixing cylinders are fixedly installed on all four sides of the outside of the mounting block, and a movable rod is slidably installed inside the fixing cylinder, with the upper end of the movable rod extending to the outside of the fixing cylinder.

[0009] Preferably, in order to break up the soil clods and facilitate subsequent mulching and compaction, a connecting chain is fixedly installed at the upper end of the movable rod, and a breaker hammer is fixedly installed at the other end of the connecting chain.

[0010] Preferably, in order to enable the movable rod to move up and down in the fixed cylinder, thereby adjusting the rotation radius of the breaker, sliding locking grooves are provided on both outer sides of the fixed cylinder. The sliding locking grooves are J-shaped, and locking rods are provided on both lower sides of the movable rod, with the locking rods slidably engaging in the sliding locking grooves.

[0011] Preferably, in order to move the movable rod, a spring is fixedly installed at the lower end of the movable rod. The spring is located inside the fixed cylinder, and the other end of the spring is fixedly connected to the lower end of the interior of the fixed cylinder.

[0012] The beneficial effects of this utility model are: the soil-moving component can move soil clods on the ground to the lower end of the mounting frame, thereby completing the aggregation of soil clods and improving the crushing effect. At the same time, the crushing component can rotate under the drive of the servo motor, thereby crushing the soil clods by the breaker hammer, avoiding the soil clods being too large to affect the subsequent mulching and compaction. In addition, when not in use, the rotation radius of the breaker hammer can be shortened, making it convenient for users to store. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] like Figures 1-6As shown, this embodiment provides a soil clod crushing mechanism for a mulched soil compactor, including a mounting frame 1. Connectors 2 for connecting to an external mulched soil compactor are fixedly installed at both ends of the mounting frame 1. U-shaped mounting plates 3 are fixedly installed on both sides of the lower end of the mounting frame 1. Soil-dispensing components 4 are installed between the mounting plates 3, located on both sides of the lower outer end of the mounting frame 1. A servo motor 5 is fixedly installed on one side of the outer edge of the mounting frame 1. A rotating shaft 6 is fixedly installed at the output end of the servo motor 5, and the rotating shaft 6 is rotatably engaged within the mounting frame 1. The rotating shaft 6 is fixedly mounted with a crushing component 7. The crushing component 7 is located inside the mounting frame 1. In use, the structure is first connected to the external mulching and compaction machine through the connector 2. During use, the soil-moving component 4 moves the soil clods on the ground to the lower end of the mounting frame 1, thereby completing the accumulation of soil clods and improving the crushing efficiency. When the soil clods are moved to the lower end of the mounting frame 1, the servo motor 5 can drive the rotating shaft 6 and the crushing component 7 to rotate, so that the soil clods can be crushed by the crushing component 7, which facilitates the subsequent mulching and compaction.

[0022] As a technical optimization solution of this utility model, specifically as follows: Figure 3 As shown, the soil-moving assembly 4 includes a control motor 401, which is fixedly installed on the lower end of the outer side of the mounting plate 3. A rotating roller 402 is fixedly installed at the output end of the control motor 401. The rotating roller 402 is rotatably engaged inside the mounting plate 3. A deflecting plate 403 is fixedly installed in a circular array on the outer side of the rotating roller 402. A rubber scraper 404 is fixedly installed on one side of each deflecting plate 403. In use, the control motor 401 can drive the rotating roller 402 to rotate, thereby driving the deflecting plate 403 and the rubber scraper 404 to rotate. At this time, the rotation direction of the control motor 401 is opposite, so that the soil clods can be moved to the lower end of the mounting frame 1 under the action of the deflecting plate 403 and the rubber scraper 404, thereby completing the accumulation of soil clods.

[0023] As a technical optimization solution of this utility model, specifically as follows: Figure 5As shown, the crushing assembly 7 includes mounting blocks 701, with an array of mounting blocks 701 fixedly mounted on a rotating shaft 6. Fixed cylinders 702 are fixedly mounted on all four outer sides of the mounting blocks 701. A movable rod 703 is slidably mounted inside the fixed cylinder 702, with its upper end extending to the outside of the fixed cylinder 702. A connecting chain 704 is fixedly mounted on the upper end of the movable rod 703, and a breaker hammer 705 is fixedly mounted on the other end of the connecting chain 704. Sliding locking grooves 706 are J-shaped on both outer sides of the fixed cylinder 702. Locking rods 707 are provided on both lower sides of the movable rod 703, slidingly engaging with the sliding locking grooves 706. A spring 708 is fixedly mounted on the lower end of the movable rod 703. Inside the fixed cylinder 702, and with the other end of the spring 708 fixedly connected to the lower end of the fixed cylinder 702, during use, the movable rod 703 is pressed by the snap-fit ​​rod 707, and then the movable rod 703 is rotated, so that the snap-fit ​​rod 707 is located in the long groove of the sliding snap-fit ​​groove 706. Under the action of the spring 708, the movable rod 703 extends out of the fixed cylinder 702, thereby increasing the rotation radius of the breaker hammer 705. After use, the reverse operation can make the movable rod 703 snap into the fixed cylinder 702, thereby reducing the rotation radius of the breaker hammer 705, making it convenient for the user to store. During crushing, the servo motor 5 can drive the rotating shaft 6 to rotate, thereby driving the crushing component 7 to rotate. The breaker hammer 705 can crush the soil clods gathered at the lower end of the mounting frame 1, completing the crushing of the soil clods.
