Description

Technical Field

[0001] The utility model relates to the technical field of harvesters, and particularly relates to a harvesting knife for a harvester that can be folded. Background Art

[0002] A harvester is an integrated agricultural machine that can complete the harvesting, threshing of crops at one time, concentrate the grains into a storage bin, and then transport the grains to a transport vehicle through a conveyor belt. It is widely used for harvesting various crops, such as wheat, rice, corn, etc. During the process of harvesting crops, a harvesting knife is needed. The harvesting knife is crucial for the durability and performance of the harvester and is an integral part of the cutting process.

[0003] The existing harvesting knife is generally arranged at the head of the harvester. During the forward movement of the harvester, the harvesting knife is driven to move close to the crops, squeezing the crops, and thus cutting the crops at the root. When in use, the harvesting efficiency depends on the width of the cutting knife. The wider the harvesting knife, the larger the area harvested by the harvester in each pass. The width of the existing cutting knife is generally larger than the width of the harvester body to increase the harvesting efficiency. However, when driving on the road, due to the large width of the harvesting knife, it is not convenient to pass through narrow positions. To solve this technical problem, the utility model proposes a harvesting knife for a harvester that can be folded. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a harvesting knife for a harvester that can be folded, which can effectively solve the problems mentioned in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A harvesting knife for a harvester that can be folded includes a conveying plate. One end of the conveying plate is provided with a fixing plate. One side of the fixing plate is provided with a movable plate. An activity mechanism is arranged on the upper parts of the movable plate and the fixing plate. A power mechanism is arranged on one side of the activity mechanism. A supporting mechanism is arranged on the upper surface of the movable plate. A fixing mechanism is arranged on the back surfaces of the fixing plate and the movable plate. A side plate is installed at the end of the movable plate. A cutting assembly is arranged on the front surfaces of the fixing plate and the movable plate.

[0007] Preferably, the activity mechanism includes a first hinge plate. A second hinge plate is arranged on the side surface of the first hinge plate. The lower surface of the first hinge plate is fixedly connected to the fixing plate. The lower surface of the second hinge plate is fixedly connected to the movable plate. A limiting rod is fixedly connected to the inner wall of the second hinge plate. The outer surface of the limiting rod is rotatably connected to the first hinge plate.

[0008] Preferably, the power mechanism comprises a fixing member, one end of which is fixedly connected to the conveying plate, and the other end of which is fixed with a protective box.

[0009] Preferably, a motor is installed inside the protection box, and the output end of the motor passes through the protection box and is fixedly connected to the limiting rod.

[0010] Preferably, the support mechanism comprises a fixed block, one end of which is fixedly connected to the movable plate, the other end of which is detachably connected to the conveying plate, and the upper end of the movable plate is fixedly connected to the support block.

[0011] Preferably, the fixing mechanism comprises a first clamping block, one side of which is fixedly connected to the fixing plate, and a second clamping block is provided on one side of the first clamping block, and the second clamping block is fixedly connected to the movable plate.

[0012] Preferably, the inner walls of the first clamping block and the second clamping block are slidably connected with a lock buckle, and the bottom of the lock buckle is threadedly connected with a threaded rod.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In the utility model, by arranging components such as movable plates and power mechanisms, two movable plates are added to the sides of the fixed plate to increase the width of the harvest, and when the harvester travels the same distance, the cutting area is increased, thereby improving the cutting efficiency, achieving the effect of improving the cutting efficiency. When the cutting is completed and it is necessary to go on the road, the movable plate is driven by the power mechanism to rotate 180 degrees, thereby rotating the movable plate to the top of the fixed plate to reduce the overall width, making the width smaller than the width of the harvester body, so as to facilitate passage in a narrow position, achieving the effect of facilitating passage, thereby solving the problem that the width of the existing cutting knife is generally larger than the width of the harvester body, making it inconvenient to pass when passing through a narrow position.

[0015] In the utility model, by arranging components such as a supporting mechanism and a fixing mechanism, when the movable plate is flipped and folded, the fixing block can be fixedly connected to the conveying plate by bolts, and at the same time, the end of the supporting block is made to support the fixing plate to increase the stability of the movable plate after folding and prevent it from shaking up and down during the walking of the harvester. When the movable plate is unfolded, the lock buckle is buckled onto the first block and the second block, and then the threaded rod is screwed on, so that the lock buckle can be fixed to the first block and the second block together to prevent the second block from moving away from the first block, thereby preventing the movable plate from moving during use.

The output end of the motor 503 penetrates the protective box 502 and is fixedly connected to the limit rod 403. The limit rod 403 can be driven to rotate by the motor 503, thereby driving the movable plate 3 to rotate, avoiding manual rotation and achieving the effect of facilitating the folding of the movable plate 3.

[0026] A supporting mechanism 6 is provided on the upper surface of the movable plate 3, and the supporting mechanism 6 includes a fixed block 601, one end of the fixed block 601 is fixedly connected to the movable plate 3, and the other end of the fixed block 601 is detachably connected to the conveying plate 1.

[0030] When the cutting is completed and it is necessary to drive on the road, the motor 503 drives the limiting rod 403 to rotate 180 degrees. The limiting rod 403 drives the movable plate 3 to rotate 180 degrees through the second hinge plate 402, so as to rotate the movable plate 3 above the fixed plate 2, as Figure 5 shown, to reduce the overall width and make the width smaller than the width of the harvester body, so as to facilitate passing through narrower positions and achieve the effect of facilitating passage.
