Description

Technical Field

[0001] This utility model is a harvester grass cutter with a flipping function. Background Technology

[0002] With societal progress and the development of agricultural technology, modern agricultural machinery is widely used in agricultural production, improving the automation level of agricultural operations. During the harvesting of crops such as wheat and rice, different regions have different requirements for the treatment of harvested straw. For example, some regions require that wheat or rice straw be crushed and returned to the field to improve soil fertility, while other regions require that the whole straw be retained for livestock feed or other uses.

[0003] Currently, most harvesters on the market are equipped with rear-mounted grass cutters to meet the needs of straw crushing. However, when farmers no longer require straw crushing, the grass cutter must be removed for whole straw collection. The existing grass cutter disassembly and assembly process is cumbersome, usually requiring multiple people to work together, which is not only time-consuming and labor-intensive but also requires additional storage space. Furthermore, disassembly is even more inconvenient during field operations, affecting work efficiency. Therefore, existing technology still falls short in terms of the flexibility and convenience of straw processing methods and urgently needs improvement. Summary of the Invention:

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a harvester grass cutter with a flipping function.

[0005] A harvester grass cutter with a flipping function is characterized by comprising a grass cutter body, a flipping mechanism, an execution mechanism, and a locking mechanism. The flipping mechanism includes a rotating shaft, which is fixedly connected to the grass cutter body and rotatably connected to the frame. The execution mechanism includes a drive gear and a driven gear. The drive gear is rotatably connected to the shaft via a bearing, and the driven gear is fixedly connected to the rotating shaft. The driven gear and the drive gear mesh. The grass cutter body has a grass-crushing mode and a grass-shredding mode depending on the flipping position. The locking mechanism is used to prevent the gears from reversing.

[0006] Furthermore, in grass-chopping mode, the grass cutter body and the frame are fixedly connected by a connecting plate.

[0007] Furthermore, the connecting plate is connected to the grass cutter body and frame by bolts.

[0008] Furthermore, in grass-cutting mode, the grass cutter body and the frame are locked together by a locking rod.

[0009] Furthermore, one end of the locking rod is connected to the grass cutter body, and the other end is detachably connected to the frame.

[0010] Furthermore, one end of the locking rod is movably sleeved on the hinge shaft and locked by a pin. A connecting shaft is provided on the frame, and the other end of the locking rod is sleeved on the connecting shaft and locked by a pin.

[0011] Furthermore, the locking mechanism is located above the drive gear. The locking mechanism includes a toothed plate, a rotating shaft, and a limiting post. The toothed plate is rotatably connected to the rotating shaft. A limiting post is provided on each side of the rotating shaft. A limiting part is provided on one side of the toothed plate. The lower end face of the limiting part is provided with a groove for cooperating with the limiting post. A triangular locking block for intervening between the gear teeth is provided below the toothed plate.

[0012] Furthermore, the grass cutter body is provided with a tail cap at the rear end, and the tail cap is connected to the grass cutter body by bolts.

[0013] Furthermore, a handle is provided on the surface of the drive gear.

[0014] Beneficial effects: Compared with the prior art, the present invention has the following advantages:

[0015] With its flip-type structure, the grass cutter can freely switch between whole grass mode and shredding mode to meet the processing needs of different crops, thereby improving the applicability and operating efficiency of the equipment.

[0016] The precise meshing of the drive gear and the driven gear ensures a smooth and stable turning process for the grass cutter, reducing energy consumption, extending equipment lifespan, and improving operational reliability.

[0017] The design incorporates anti-reverse features such as a locking plate and limit pins to effectively lock the gears, preventing equipment malfunctions caused by gear reversal during operation and improving operational safety and equipment stability.

[0018] The connecting plate and locking rod are used to fix the grass shredding mode and the grass whole mode respectively. They support multiple installation methods such as bolts, pins, and quick-release structures, which not only ensures stability but also facilitates disassembly, replacement and maintenance, improving ease of use.

[0019] The tail cap is connected with adjustable bolts to seal the tail of the grass cutter, effectively preventing grass fragments from flying and improving operational safety. It also facilitates cleaning and maintenance, extending the service life of the equipment.

[0020] By disassembling the connecting plate, adjusting the caliper plate, flipping the grass cutter body, and installing the locking rod, the mode can be easily switched, reducing the difficulty of manual operation and improving the smoothness of operation and production efficiency.

Detailed Implementation

[0030] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0031] A harvester grass cutter with a flipping function includes a grass cutter body 1, a flipping mechanism, an actuator, and a locking mechanism. The flipping mechanism includes a rotating shaft, which is fixedly connected to the grass cutter body 1 and rotatably connected to the frame. The actuator includes a drive gear 5 and a driven gear 6. The drive gear 5 is rotatably connected to the shaft via bearings, and the driven gear 6 is fixedly connected to the rotating shaft. The two mesh with each other, thereby driving the grass cutter body 1 to flip. The grass cutter body 1 has a grass-chopping mode and a grass-shredding mode depending on the flipping position. The locking mechanism is used to prevent the gears from reversing.

[0032] It should be noted that the grass cutter body has a box structure, and the rotating shaft 9 passes through the left side plate 10 and the right side plate 11 of the grass cutter body and is fixedly connected.

[0033] This grass cutter uses a rotating shaft to flip the cutter body 1, switching between different operating modes. The drive gear 5 drives the driven gear 6 to rotate, causing the rotating shaft to flip the cutter body 1 to the set position. The locking mechanism uses a limit device to prevent the gear from reversing, ensuring that the grass cutter operates stably in the specified mode.

[0034] This design enhances the adaptability of the grass cutter, allowing it to flexibly switch between different operating modes to meet various crop processing needs. Simultaneously, the locking mechanism effectively prevents gear reversal, improving the equipment's safety and stability.

[0035] In one possible implementation, in grass-chopping mode, the grass cutter body 1 and the frame are fixedly connected by a connecting plate 3.

[0036] When the grass cutter is in shredding mode, the connecting plate 3 supports and stabilizes the grass cutter body 1, ensuring that it does not shift during shredding operations. This fixed connection guarantees stability in shredding mode and improves cutting efficiency.

[0037] The connecting plate 3 can be fixed in different ways, such as welding or quick-release structure, to facilitate maintenance and replacement.

[0038] In one possible implementation, the connecting plate 3 is connected to the grass cutter body 1 and the frame by bolts.

[0039] The bolted connection ensures that the connecting plate 3 can be reliably fixed between the frame and the grass cutter body 1, while also providing some ease of disassembly.

[0040] In one possible implementation, in the grass-cutting mode, the cutter body 1 and the frame are locked together by a locking rod 4. When the cutter is flipped to the grass-cutting mode, the locking rod 4 is used to fix the cutter body 1, ensuring stability during operation. The locking rod 4 provides additional fixing effect to ensure stability in the grass-cutting mode.

[0041] In one possible implementation, one end of the locking rod 4 is connected to the cutter body 1, and the other end is detachably connected to the frame. The locking rod 4 is fixed to the cutter body 1 at one end and detachably connected to the frame at the other end for easy adjustment and maintenance. This detachable connection improves maintenance convenience while ensuring the reliability of the locking rod 4.

[0042] In one possible implementation, one end of the locking rod 4 is movably sleeved on the hinge shaft and locked by a pin. A connecting shaft is provided on the frame, and the other end of the locking rod 4 is sleeved on the connecting shaft and locked by a pin. Both ends of the locking rod 4 are fixed to the hinge shaft and the connecting shaft respectively by pins, achieving a stable lock and providing a certain degree of adjustability. The pin locking method facilitates disassembly and improves the maintainability of the equipment.

[0043] In one possible implementation, the locking mechanism is located above the drive gear 5. The locking mechanism includes a toothed plate, a rotating shaft, and limiting posts 8. The toothed plate is rotatably connected to the rotating shaft. A limiting post 8 is provided on each side of the rotating shaft. A limiting part is provided on one side of the toothed plate, and the lower end face of the limiting part has a groove for engaging with the limiting post 8. A triangular locking block is provided below the toothed plate for interlocking between the gear teeth. The locking mechanism achieves precise locking by engaging the limiting part of the toothed plate with the limiting post 8, preventing gear reversal. This mechanism effectively improves the stability and safety of equipment operation.

[0044] Specifically, such as Figure 4 As shown, when the caliper plate is positioned as depicted, the gear rotates in the direction of the arrow. Through the locking block, the gear drives the caliper plate to rotate in the opposite direction. At this time, the groove of the caliper plate's limiting part and the limiting post will not interfere with each other, and the gear can rotate normally. However, when the gear rotates in the opposite direction of the arrow, the caliper plate will tend to move in the direction of the arrow. At this time, the groove of the caliper plate's limiting part and the limiting post will interfere with each other. The limiting post will prevent the caliper plate from moving, and thus prevent the gear from rotating, thereby acting as a ratchet. At the same time, compared with a ratchet, it is more convenient to reset the equipment. Similarly, when the caliper plate is positioned as shown, the groove of the limiting part and the limiting post will interfere with each other. The limiting post will prevent the caliper plate from moving, and thus prevent the gear from rotating, thereby acting as a ratchet. Figure 5 The same applies to placement.

[0045] In one possible implementation, the grass cutter body 1 is provided with a tail cap 2 at its rear end, and the tail cap 2 is connected to the grass cutter body 1 by bolts. The tail cap 2 is used to seal the tail end of the grass cutter, preventing grass clippings from flying and improving safety. The tail cap 2 has a simple and reliable structure and is easy to install. By removing the bolts and adjusting their position in the arc-shaped waist hole, the angle of the tail cap 2 can be adjusted according to the actual situation, such as... Figure 6 and Figure 7 As shown, the tail cap can be adjusted to any angle between the maximum and minimum angles shown in the diagram.

[0046] In one possible implementation, the grass cutter body is provided with a fixed blade mechanism.

[0047] Instructions for use: When switching from shredding mode to whole grass mode, first loosen the tensioning device and remove the belt. Then, loosen the bolts on connecting plate 3 and remove connecting plate 3. Figure 4 Install the caliper plate 7 at the indicated position to ensure that the drive gear 5 rotates only in the desired direction. Hold the handle on the drive gear 5 and turn it to flip the grooving body upwards. Then, attach one end of the locking rod 4 to the connecting shaft on the frame and secure it with a pin.

[0048] To switch back from haymaking mode to shredding mode, reverse the steps described above, while ensuring that the caliper plate 7 is positioned correctly. Figure 5 The location shown.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
