Description

Technical Field

[0001] This utility model is an anti-clogging press for corn harvesters. Background Technology

[0002] In agricultural machinery, peeling machine assemblies are widely used in crop processing, primarily for peeling, cleaning, and lifting the kernels from the ears of grain. Existing peeling machine assemblies typically include a kernel lifting assembly, a press assembly, a peeling machine assembly, and a peeling and cleaning assembly. The kernel lifting assembly transports the ears of grain to the peeling machine assembly, where they undergo further processing to obtain clean kernels.

[0003] However, in practical applications of existing grain lifting assemblies, certain defects may exist in the grain lifting assembly during operation. For example, when there are many ears of grain, the elevator may simultaneously transport a large number of ears to the press, potentially causing blockages at the front end of the press, especially in the first star wheel area, thus affecting the smooth operation of the entire grain lifting process. This blockage not only reduces the equipment's efficiency but may also lead to unstable operation, affecting the processing quality of the crops. Furthermore, the existing press assembly lacks a forced feeding auxiliary structure when feeding ears, making it difficult to control the speed and uniformity of the ears entering the grain lifting device, further impacting the grain lifting effect.

[0004] To address the aforementioned issues, existing technologies urgently need to optimize and improve the press assembly to add a forced feeding function, prevent blockages caused by the accumulation of fruit ears, and improve the overall operating efficiency and stability of the peeling machine assembly. Utility model content:

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an anti-clogging press for corn harvesters.

[0006] An anti-clogging press for a corn harvester includes a pressing star wheel assembly and a forced feeding mechanism. The forced feeding mechanism is installed at the front end of the press and includes a feeding shaft and multiple dial wheels. The feeding shaft is rotatably connected to the press housing, and the dial wheels are fixedly connected to the feeding shaft at intervals. Each dial wheel includes a hub and dial blocks. Two centrally symmetrical dial blocks are provided on the outer side of the hub. Each dial block is a straight structure that gradually tapers from one end to the other, with a notch on one side. The notch and the connection point are arc-shaped chamfered structures. The dial blocks on adjacent dial wheels are staggered.

[0007] Furthermore, the feed shaft is a cuboid structure with cylindrical connecting parts at the center of both ends. Bearings are sleeved on the outside of the connecting parts, and the bearings are installed in bearing seats, which are installed on the press housing.

[0008] Furthermore, a spacer is provided between adjacent dials, and the spacer is fitted onto the feed shaft.

[0009] Furthermore, cotter pins are provided on the outer side of the dials at both ends of the feed shaft, and the cotter pins are inserted radially into the feed shaft.

[0010] Furthermore, the stagger angle of the shift blocks on adjacent shift wheels is 90°.

[0011] Furthermore, the material of the pry block is a high-strength wear-resistant material.

[0012] Furthermore, the high-strength wear-resistant material is stainless steel or alloy steel.

[0013] Beneficial effects: Compared with the prior art, the present invention has the following advantages:

[0014] By arranging the blocks in an alternating pattern, the straw can be gradually broken and dispersed during the feeding process, reducing the risk of straw accumulation or tangling and improving the continuity and stability of feeding.

[0015] The pusher blocks are designed with 90° staggered angles, which ensures that the pusher blocks act evenly on the straw when rotating, enhancing the crushing ability and improving the straw conveying efficiency.

[0016] The tapering straight structure and rounded chamfer design of the prying blocks help reduce shear resistance, making the straw prying smoother and further reducing the risk of clogging.

[0017] The cuboid structure of the feed shaft restricts the axial degree of freedom of the dial wheel relative to the feed shaft, while the spacer and cotter pin restrict the axial degree of freedom of the dial wheel relative to the feed shaft, thus ensuring that the dial wheel will not shift or wobble during operation.

[0018] The paddles are made of high-strength wear-resistant materials (such as stainless steel or alloy steel) to improve impact resistance and wear resistance, adapt to the high-intensity working environment of corn harvesters, and extend the equipment life.

[0019] The feed shaft is supported by bearings at both ends to ensure smooth rotation, reduce frictional loss, and improve the reliability of equipment operation. Spacers are used to appropriately space the feed rollers to prevent friction between them and improve the working efficiency of the feeding mechanism. Attached Figure Description

[0025] 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.

[0026] An anti-clogging press for a corn harvester includes a pressing star wheel assembly 2 and a forced feeding mechanism 1. The forced feeding mechanism 1 is installed at the front end of the press and consists of a feeding shaft 7 and multiple deflector wheels 3. The feeding shaft 7 is rotatably connected to the press housing, and the deflector wheels 3 are fixedly mounted on the feeding shaft 7 at intervals. Each deflector wheel 3 consists of a hub 8 and deflector blocks 9, with two centrally symmetrical deflector blocks 9 on the outer side of the hub 8. The deflector blocks 9 have a straight structure that gradually tapers from one end to the other, with a notch on one side, and the notch and the connection point are rounded with a chamfered structure. The deflector blocks 9 on adjacent deflector wheels 3 are staggered, thereby effectively crushing straw during feeding and reducing the risk of clogging.

[0027] In the above embodiment, the feed shaft 7 adopts a cuboid structure with cylindrical connecting parts at the center of both ends. Bearings are sleeved on the outside of the connecting parts, and the bearings are installed in the bearing seats 6 and fixed to the press housing, so that the feed shaft 7 can rotate stably, improving the reliability and durability of the device.

[0028] Further design optimization involves providing a spacer 4 between adjacent dial wheels 3, which is fitted onto the feed shaft 7 to ensure a reasonable distance between the dial wheels 3, prevent excessive contact or friction between the dial wheels 3, and improve the working efficiency of the feeding mechanism.

[0029] In addition, cotter pins are provided on the outer side of the dial wheels 3 located at both ends of the feed shaft 7. The cotter pins are inserted radially into the pin holes 5 on the feed shaft 7 to ensure the stable fixation of the dial wheels 3 and prevent the dial wheels 3 from axially moving or falling off when running at high speed.

[0030] To enhance the crushing effect, the staggered angle of the paddle blocks 9 on adjacent paddle wheels 3 is set to 90°, so that the paddle blocks 9 can act evenly on the straw when rotating, improving crushing and conveying efficiency and effectively reducing the risk of blockage.

[0031] To improve durability, the material of the paddle block 9 is selected as high-strength wear-resistant material, such as stainless steel or alloy steel, to enhance the impact resistance and wear resistance of the paddle block 9, thereby adapting to the high-intensity working environment of the corn harvester and extending the service life of the equipment.

[0032] Specifically, the anti-clogging press of the present invention uses a forced feeding mechanism 1 to evenly transport harvested corn stalks into the pressing star wheel assembly 2. The feeding shaft 7 rotates under the action of an external drive device, driving multiple dial wheels 3 to rotate synchronously. When the dial wheels 3 rotate, the dial blocks 9 mounted on them sequentially contact the stalks, using the rotational force of the dial blocks 9 to forcibly move and guide the stalks, thereby preventing the stalks from accumulating or tangling during feeding and improving the continuity and stability of feeding.

[0033] The feed block 9 employs a centrally symmetrical structure, ensuring even application of force to the straw during rotation and preventing eccentric forces, thus guaranteeing stable feeding. Simultaneously, the tapering straight structure of feed block 9 facilitates gradual separation and arrangement of the straw, preventing sudden jamming. The notches and chamfered edges on the sides of feed block 9 reduce shear resistance to the straw, making it smoother when moving the straw and further minimizing the risk of blockage.

[0034] In practical work, the paddle blocks 9 on adjacent paddle wheels 3 are arranged in a 90° staggered manner. That is, when one paddle block 9 moves the straw, the paddle blocks 9 on the adjacent paddle wheels 3 can further move and guide the straw at the next time point. This staggered layout can achieve more efficient straw conveying, avoid the accumulation problem caused by pushing in one direction, and improve feeding efficiency.

[0035] The cuboid structure of the feed shaft 7 restricts the axial degree of freedom of the dial wheel 3 relative to the feed shaft 7, and the spacer 4 and cotter pin restrict the axial degree of freedom of the dial wheel 3 relative to the feed shaft 7, thereby ensuring that the dial wheel 3 will not shift or wobble during operation.

[0036] 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.
