Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, specifically a corn stalk crushing device. Background Technology

[0002] With the continuous improvement of agricultural mechanization, the treatment of corn stalks has become an important issue in the agricultural field. Corn stalks are not only a byproduct of agricultural production, but also contain abundant organic matter. Effective recycling and utilization of corn stalks can greatly promote resource recycling and reduce environmental pollution. However, existing corn stalk crushing devices generally have some shortcomings in the processing process, especially for continuous and variable-quantity feeding, resulting in problems such as material jamming and uneven feeding, which seriously affect the normal operating efficiency of the equipment.

[0003] Traditional corn stalk crushing devices primarily rely on manual labor or mechanical conveyor belts for feeding. Due to the unstable nature of corn stalks, significant variations in moisture content, and inconsistent stalk shapes, stalks often accumulate at the feed inlet or in the feeding system, causing jamming. Jamming not only increases equipment wear and tear and the failure rate but also leads to uneven feeding, affecting the crushing effect and even causing equipment shutdown.

[0004] Currently, to address these issues, some crushing equipment on the market is equipped with electric feeding devices and automatic adjustment devices. However, these devices are mostly designed for single-volume feeding and lack effective solutions for handling continuous, variable-volume feeding. More importantly, due to the significant differences in the amount, shape, and moisture content of corn stalks, existing crushing equipment struggles to achieve intelligent adjustment, still exhibiting problems such as uneven feeding and clogging, which often lead to low equipment operating efficiency. Utility Model Content

[0005] To overcome the problems of material jamming and uneven feeding in existing corn stalk crushing devices when handling continuous and variable feeding, this invention provides a novel corn stalk crushing device. By optimizing the feeding system and adopting an intelligent adjustment mechanism, the feeding speed can be automatically adjusted according to the amount of stalks fed, ensuring uniform feeding and avoiding material jamming.

[0006] Specifically, it includes a hopper for receiving corn stalks and a crusher that connects and cooperates with the discharge end of the hopper. The characteristic of the hopper discharge end is provided with a sliding baffle. The sliding baffle slides relative to the opening of the hopper so that the sliding baffle and the bottom surface of the hopper form a discharge port with a variable area.

[0007] Preferably, an inclined cone guide groove is provided between the discharge port and the feed port of the crusher, and the side of the inclined cone guide groove closest to the feed port of the crusher has a smaller diameter end.

[0008] Preferably, a transition slope is installed between the bottom surface of the hopper and the edge of the inclined cone guide trough.

[0009] Preferably, guide wheels that rotate and are in close contact with the inner wall of the hopper are installed on both sides of the hopper body. The two guide wheels are synchronously powered through a gear transmission unit, and the crusher and the gear transmission unit are synchronously powered.

[0010] Preferably, each of the guide wheels has multiple outwardly protruding tooth-shaped protrusions on its axial surface.

[0011] Preferably, the bottom wall of the inclined cone guide trough is provided with an auxiliary material conveyor belt, and the direction of operation of the auxiliary material conveyor belt is such that its top surface points towards the feed inlet of the crusher.

[0012] Preferably, the axis of the inclined cone guide trough is inclined towards the side closer to the feed inlet of the crusher.

[0013] Compared with the prior art, the present invention provides a corn stalk crushing device, which has the following beneficial effects:

[0014] 1. This novel corn stalk crushing device optimizes existing technologies to address their shortcomings, offering significant advantages. By installing a sliding baffle at the hopper's discharge end, the discharge port area can be flexibly adjusted, automatically regulating the feeding speed based on the amount of stalks fed, effectively preventing material jamming and ensuring uniform feeding. The inclined cone guide chute design allows stalks to enter the crusher more smoothly, and the transition slope between the hopper bottom and the guide chute further reduces material accumulation. Simultaneously, the guide wheels and toothed protrusions guide and comb the stalks, ensuring orderly transport, greatly improving the equipment's efficiency and stability, and promoting the effective processing and recycling of corn stalks.

[0015] 2. Effectively solves the problems of traditional equipment in handling continuous and variable-quantity feeding. The auxiliary material conveyor belt is set on the bottom wall of the inclined cone guide chute, which helps to transport materials to the feed inlet of the crusher and avoids material accumulation in the guide chute. The axis of the inclined cone guide chute is inclined towards the feed inlet, optimizing the material conveying path. In addition, the crusher and the gear transmission unit are synchronously powered, driving the guide wheel to rotate synchronously, making the entire feeding system more intelligent. These improvements effectively overcome problems such as uneven feeding and blockage, reduce equipment wear and failure rate, and improve crushing effect and equipment operating efficiency.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example

[0021] The following is combined Figure 1 and Figure 2 This application introduces a corn stalk crushing device, comprising a hopper 1 for receiving corn stalks and a crusher 2 connected to the discharge end of the hopper 1. The device is characterized in that the discharge end of the hopper 1 is provided with a sliding baffle 3, which slides relative to the opening of the hopper 1, forming a discharge port 4 with a variable area between the sliding baffle 3 and the bottom surface of the hopper 1. A sloping conical guide groove 5 is provided between the discharge port 4 and the inlet of the crusher 2, with the side of the sloping conical guide groove 5 near the inlet of the crusher 2 having a smaller diameter end. A transition slope 6 is installed between the bottom surface of the hopper 1 and the edge of the sloping conical guide groove 5. Guide wheels 8, which rotate and are tightly attached to the inner wall of the hopper 1, are mounted on both side walls of the hopper 1. The two guide wheels 8 are synchronously powered through a gear transmission unit 10, and the crusher 2 is synchronously powered through the gear transmission unit 10. Each guide wheel 8 has multiple outwardly protruding toothed protrusions 9 on its axial surface. The bottom wall of the inclined cone-shaped material guide trough 5 is equipped with an auxiliary material conveyor belt 7, which rotates in the direction that its top surface points towards the feed inlet of the crusher 2. The axis of the inclined cone-shaped material guide trough 5 is inclined towards the side closer to the feed inlet of the crusher 2.

[0022] The hopper 1 is one of the key components of this application, and its main function is to collect and guide corn stalks into the crusher 2. The bottom surface of the hopper 1 is designed with an adjustable sliding baffle 3. The function of the sliding baffle 3 is to adjust the opening size of the discharge port 4 to accommodate different feeding amounts. Specifically, the sliding baffle 3 slides relative to the opening of the hopper 1, and by adjusting the position of the baffle, the area of ​​the discharge port 4 is changed. In this way, when the demand for stalk processing is large, the discharge port 4 can be increased to increase production efficiency; when the load on the crusher 2 reaches its maximum value, the discharge port 4 can be reduced to decrease the equipment load and ensure equipment performance. Through this structural design, it is possible to ensure that corn stalks can flow smoothly into the crusher 2 under different feeding amounts.

[0023] To better guide the corn stalks towards the feed inlet of the crusher 2, an inclined conical guide chute 5 is installed between the bottom of the hopper 1 and the feed inlet of the crusher 2. The function of the inclined conical guide chute 5 is to help guide the corn stalks into the crusher 2 evenly and smoothly through its unique structure. The smaller diameter side of the inclined conical guide chute 5 near the crusher 2 effectively controls the flow speed of the stalks, ensuring that the corn stalks do not accumulate or clog during their entry into the crusher 2.

[0024] An auxiliary material conveyor belt 7 is installed on the bottom wall of the inclined cone-shaped feed chute 5. The auxiliary material conveyor belt 7 runs in the direction of the feed inlet of the crusher 2. The auxiliary material conveyor belt 7 can further help the corn stalks to pass evenly through the feed chute into the crusher 2, and can also prevent the stalks from accumulating in the feed chute, increasing the stability during transportation.

[0025] To enhance the guiding effect during the feeding process, two guide wheels 8 are installed on both side walls of the hopper 1. The guide wheels 8 rotate synchronously through the gear transmission unit 10 to ensure that the straw maintains a stable flow during transportation. The toothed protrusions 9 of the guide wheels 8 can effectively contact the straw and push it forward, avoiding the straw from getting stuck during the feeding process.

[0026] Each guide wheel 8 has multiple outwardly protruding toothed protrusions 9 on its axial surface. These protrusions help the straw pass smoothly through the guide wheel 8 and ensure that the straw does not accumulate or become blocked during the conveying process.

[0027] The rotation of the guide wheel 8 is synchronously powered by the gear transmission unit 10 and the crusher 2, ensuring that the power transmission between the guide wheel 8 and the crusher 2 is coordinated and consistent, achieving efficient feeding control.

[0028] To further optimize the feeding process, this invention designs a transition slope between the bottom surface of the hopper 1 and the edge of the inclined cone guide trough 5. The function of this slope is to help the corn stalks smoothly transition into the inclined cone guide trough 5, thereby reducing material stagnation or jamming during the feeding process.

[0029] The purpose of setting the transition slope is to connect the transfer of corn stalks between the bottom surface of the bucket 1 and the inclined cone guide trough 5. In some embodiments, holes can be drilled in the transition slope to form a screen plate structure, so that when the corn stalks are transferred between the bottom surface of the bucket 1 and the inclined cone guide trough 5, impurities such as soil and gravel can be shaken off, protecting the crusher 2.

[0030] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
