Description

Technical Field

[0001] This invention belongs to the technical field of straw processing equipment, and specifically relates to a straw processing device. Background Technology

[0002] After harvesting, crop stalks (such as corn stalks) are often used to make feed. Before making feed, the stalks need to be cut and crushed. During the crushing process, a lot of dust is generated. People use filters to remove the dust. However, due to the large amount of dust, the filters clog quickly and need to be cleaned frequently, which increases the labor intensity of users. Summary of the Invention

[0003] In view of the problems existing in the prior art, the purpose of the present invention is to provide a straw processing device to solve the above-mentioned technical problems.

[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solution: A straw processing device includes a housing with a feed inlet on one side and a discharge outlet on the other side. A processing assembly for crushing straw is disposed within the housing. A dust collection box is mounted on the housing, with an air outlet on the dust collection box. A fan is installed on the dust collection box corresponding to the air outlet. A partition is disposed within the dust collection box, dividing the internal space into a first chamber and a second chamber. The housing is connected to the first chamber. Ventilation openings are provided on the partition. Multiple filter screens are installed in the first chamber. When clogged, the filter screens can deform and pass through the ventilation openings. Each filter screen can be individually fitted to the partition.

[0005] Preferably, a plurality of magnets are arranged circumferentially near the edge of the partition, and a slide rail is fixed on the partition outside the magnets, and the filter screen is slidably connected to the slide rail; a magnet is fixed on the filter screen at the position corresponding to the magnet, and adjacent filter screens are connected by a connecting rope.

[0006] Preferably, the filter screen has a connection hole corresponding to the position of the slide rail, and the slide rail passes through the connection hole.

[0007] Preferably, a movable ring is fitted on the slide rail, and a clip is provided on the movable ring, which clamps the edge of the filter screen.

[0008] Preferably, the housing has an opening for replacing the filter screen on the side away from the air outlet, and a baffle for blocking the opening is detachably connected to the housing.

[0009] Preferably, a slider is provided on the inner side of the opening on the housing, and the slider is provided with a socket for inserting a slide rail, and the baffle presses the slider against the housing.

[0010] Preferably, the slide rail is a guide rod with a smooth surface.

[0011] Preferably, the processing assembly includes an extrusion roller group and a cutting device; the extrusion roller group includes a first extrusion roller and a second extrusion roller disposed within a housing, the first extrusion roller being located above the second extrusion roller and having a gap between them, and a drive device for driving the first extrusion roller and the second extrusion roller to rotate is mounted on the housing; the cutting device includes a motor and a blade mounted on the motor shaft; the extrusion roller group is located between the cutting device and the feed inlet.

[0012] Preferably, a conveyor belt is provided inside the housing near the bottom.

[0013] Preferably, the first and second extrusion rollers are provided with convex ridges in the circumferential direction.

[0014] When the straw processing device provided by this invention is in use, the straw enters the shell through the feed inlet, is cut and crushed by the processing components, and is discharged through the discharge outlet. During the crushing process, dust first enters the first chamber under the action of the fan and is blocked by the filter screen attached to the baffle. When the filter screen is blocked, it deforms and passes through the ventilation port. The adjacent filter screen plays a filtering role. This process is repeated, so that people do not need to clean it frequently during use, which reduces the labor intensity of the user. Attached Figure Description

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0017] In this embodiment, the present invention provides a straw processing device, see [example]. Figure 1 and Figure 2The device includes a housing 10, with an inlet 11 on one side and an outlet 12 on the other side. A processing assembly for crushing straw is located inside the housing. A dust collector 20 is mounted on the housing, with an air outlet 21. A fan 22 is installed on the dust collector corresponding to the air outlet. A partition 23 is located inside the dust collector, dividing the internal space into a first chamber 24 and a second chamber 25. The interior of the housing communicates with the first chamber. Ventilation openings 26 are provided on the partition. Multiple filters 27 are installed in the first chamber. When clogged, the filters can deform and pass through the ventilation openings, and each filter can be individually fitted to the partition. In one specific implementation, a plurality of magnets 28 are circumferentially arranged near the edge of the partition. A slide rail 29 is fixed on the partition outside the magnets, and the filter screen is slidably connected to the slide rail. A magnet 271 is fixed on the filter screen at the position corresponding to the magnet. Adjacent filter screens are connected by a connecting rope 272. A connecting hole is provided on the filter screen at the position corresponding to the slide rail, and the slide rail passes through the connecting hole. During manufacturing, the diameter of the connecting hole is slightly larger than the diameter of the slide rail. In the above embodiment, the processing component can use existing processing components, such as rotating blades. In this embodiment, the processing component includes an extrusion roller group and a cutting device. The extrusion roller group includes a first extrusion roller 31 and a second extrusion roller 32 disposed in the housing. The first extrusion roller is located above the second extrusion roller and there is a gap between them. A drive device for driving the first extrusion roller and the second extrusion roller to rotate is installed on the housing. The drive device can use two motors or a single motor with a gear set, as long as it can achieve the desired result. Figure 1 The first extrusion roller rotates counterclockwise and the second extrusion roller rotates clockwise; the cutting device includes a motor 41 and a blade 42 mounted on the motor shaft; the extrusion roller group is located between the cutting device and the feed inlet.

[0018] In use, the straw processing device described above allows the straw to enter the housing through the feed inlet. It first passes between two extrusion rollers, which simultaneously compress and move the straw forward. This compression disrupts the overall structure, making it easier for the straw to be cut and pulverized by the blades in the blade chamber, preventing the blades from getting stuck. After being cut and pulverized, the straw is discharged through the discharge outlet. To facilitate straw discharge, a conveyor belt 50 can be installed near the bottom of the housing. The installation of the conveyor belt is well-known to those skilled in the art and will not be described in detail here. During the pulverization process, dust enters the first chamber under the action of the fan and is blocked by a filter screen attached to the baffle. When the filter screen becomes clogged, the negative pressure generated by the fan in the second chamber attracts the filter screen, causing the center of the filter screen to tend to concave towards the vent. After overcoming the attraction of the magnets and the magnetic body, the filter screen's edge is pulled towards the center, eventually breaking down the edge. Due to the restriction of the ventilation opening, the filter screen indents into the ventilation hole, forming a net-like shape. During this process, pulling the adjacent filter screen towards the partition moves it closer. The portion of the net-like filter screen corresponding to the outer side of the ventilation opening filters dust, and the dust entering the net-like filter screen is ultimately encased by it. The magnets near the edge of the net-like filter screen attract each other, eventually sealing the net-like filter screen, which then falls into the second chamber. The second chamber is connected to the first chamber, and adjacent filter screens continue to filter. This process repeats. It should be noted that when adjacent filter screens move close to the partition, the attraction of the magnets and the magnetic body allows the filter screen and partition to adhere, eliminating the need for a rope to fully pull the filter screen to adhere to the partition. In the above embodiment, the magnets can be electromagnets or permanent magnets, and the magnetic body can be a permanent magnet. Of course, in actual manufacturing, the magnets on the partition can also be replaced with iron blocks, which is well known to those skilled in the art and will not be elaborated here. As a preferred implementation method, see [link to relevant documentation]. Figure 1 and Figure 3 The housing has an opening 13 for replacing the filter screen on the side away from the air outlet. A baffle 14 for blocking the opening is detachably connected to the housing. A slider 15 is provided on the housing inside the opening. The slider has a socket 16 for inserting a slide rail. The baffle holds the slider against the housing. During manufacturing, a groove of the same length as the slider can be provided on the inside of the housing. Preferably, the slide rail can be removed from the groove.

[0019] See Figure 4In the above embodiments, the filter screen can be fixed without using the slide rail through the connecting hole. Instead, a moving ring 273 is directly fitted onto the slide rail, and a clip 274 is provided on the moving ring. The clip clamps the edge of the filter screen. This structure does not damage the filter screen during use; the filter screen and slide rail can be separated simply by overcoming the friction of the clips. The slide rail is generally a smooth-surfaced guide rod. When using the moving ring and clips, the slider can also be directly fixed to the housing.

[0020] To increase the crushing effect of the extrusion rollers on the straw, convex ridges can be provided circumferentially on the first and second extrusion rollers.

[0021] It should be noted that, in the above embodiments, a support plate can also be provided on the shell at the position corresponding to the feed inlet to temporarily support the straw, and a support leg is provided at the bottom of the shell to elevate the shell for easy collection of the crushed straw. The blades mentioned above can be set vertically or horizontally, and can be set as one set or multiple sets; no specific limitation is made here.

[0022] The embodiments described above are merely illustrative of implementation methods of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
