Description

Technical Field

[0001] The utility model relates to the technical field of potato harvesting equipment, in particular to a novel clutch dedicated to a potato harvester. Background Art

[0002] In potato harvesting, the clutch, as one of the key components of a potato harvester, plays a vital role. Efficient and low-loss operation significantly improves harvesting efficiency and saves time. The clutch also provides strong support for the potato harvester's operation.

[0003] When a potato harvester is operating, it's very easy for seedlings to become entangled or encounter obstacles. In these situations, it's necessary to promptly disconnect the power source from the machine's actuators, severing the entire power transmission. Failure to do so would severely damage the harvester's weak points, shorten its lifespan, increase maintenance costs, and compromise the quality and efficiency of the potato harvest. Therefore, a new clutch specifically designed for potato harvesters has been designed to provide protection during the potato harvesting process. Summary of the Invention

[0004] The purpose of this utility model is to solve the above problems and research and design a new type of clutch for potato harvesters. The clutch is easy to install, and the two shafts are relatively stable after being connected, and can maintain a certain position without relative slippage, and it is easy to engage and disengage during operation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a potato harvester clutch primarily comprises a clutch fixed pawl, a clutch sliding pawl, a clutch sliding shaft, a compression spring, a clutch housing sprocket, a shift fork, an electronic push rod, a clutch block, a shift fork block A, and a shift fork block B. The clutch engages and disengages to transmit and disconnect power to the entire machine.

[0006] As a preferred embodiment of the present invention, the clutch adopts a tooth-type structure with spiral teeth. This structure is clear, the overall dimensions are small, and it is easy to manufacture. The teeth are not easily damaged by collision. In addition, the spiral teeth can transmit greater torque, which ensures a more stable clutch during operation and prevents slippage.

[0007] As a preferred embodiment of the present invention, the clutch lacks an automatic disengagement force. Therefore, an electronic push rod and shift fork are designed to act on the clutch sliding shaft. If the machine encounters a dangerous situation during operation, such as a stall or unusual noise, the operator can promptly detect it and control the electronic push rod. The electronic push rod drives the shift fork, which in turn drives the sliding shaft, causing all three to move simultaneously in the clutch disengagement direction, thereby disengaging the clutch. This process is relatively quick and ensures complete clutch disengagement, significantly reducing operational risks.

[0008] As a preferred embodiment of the present invention, the clutch is equipped with a compression spring. The spring is always in a stretched state, thus driving the clutch sliding pawl and the clutch fixed pawl toward engagement. During normal operation, the spring maintains a tight engagement between the two, ensuring proper power transmission throughout the machine. When reengagement is required after disengagement, the compression spring, due to its ability to recover to its original length, quickly reengages the two. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The present invention is described in further detail below with reference to the accompanying drawings and specific embodiments: Figure 1 and Figure 2 As shown, a schematic structural diagram of a new type of clutch for potato harvesters of the present invention is given. The present invention generally consists of a clutch fixed claw 1, a clutch sliding claw 2, a clutch sliding shaft 3, a compression spring 4, a clutch housing sprocket 5, a shift fork 6, an electronic push rod 7, a clutch block 8, a shift fork block A 9, and a shift fork block B 10.

[0013] like Figure 1 and Figure 2 As shown, the clutch fixed claw 1 and the clutch sliding claw 2 are spirally meshed with each other and installed in the clutch housing chain 5. One side of the compression spring 4 rests on the plane of the clutch sliding claw 2, and the other side rests on the clutch housing sprocket 5. The electronic push rod 7 is welded to the shift fork 6. The shift fork 6 is installed on the clutch sliding shaft 3. The clutch sliding shaft 3 is connected to the clutch sliding claw 2 through a flat key. The clutch block 8 is installed on both sides of the clutch housing sprocket 5. The shift fork block A 9 and the shift fork block B 10 are installed on both sides of the shift fork 6.

[0014] The following describes the operating principle of this utility model. The clutch is installed to the left rear of the machine's forward direction, connected to the potato harvester's engine on one side and to the reducer's power input shaft on the other. During normal operation, the clutch engages, transmitting power normally. If an obstruction occurs, the shift fork is controlled to disengage the clutch's fixed and sliding claws, cutting off the power source and protecting the remaining components. Once the problem is resolved, the clutch reengages, and the potato harvester resumes operation.

[0015] The utility model can quickly transmit and cut off the power of the whole machine at any time according to the actual working situation during the potato harvester's harvesting process, thereby protecting the machine to a greater extent, reducing the probability of danger, and improving the efficiency of potato harvesting.
