Description

Technical Field

[0001] The utility model relates to the technical field of straw crushing, in particular to a straw processing crushing device with a dust processing function. Background Art

[0002] A straw crusher is a mechanical device specially used to crush straw and other crop residues into small particles for subsequent use. The crushed straw particles can be used in biomass energy, animal feed, organic fertilizer and other fields, avoiding the wasteful burning of these crop straws, protecting the environment well and effectively developing renewable energy.

[0003] Existing pulverizers will generate a large amount of dust during the straw pulverization process. If not effectively treated, the dust will drift with the air. The dust will not only cause great harm to the human respiratory system, but also cause serious pollution to the surrounding environment.

[0004] For example, the straw crusher disclosed in the announcement number CN203015494U does not have a dust treatment function. The dust generated when the straw is crushed will be discharged directly from the discharge port along with the straw. The dust will drift with the air and cause serious pollution to the surrounding environment, including air pollution and soil pollution. In today's era of environmental protection, this type of straw crusher may not meet the requirements of environmental protection laws and regulations and there is a risk of being restricted in use.

[0005] Therefore, it is necessary to invent a straw processing pulverizing device with dust handling function to solve the above problems. Utility Model Content

[0008] Preferably, the large gear and the small gear are meshingly connected, and the shafts of the large gear and the small gear are fixedly connected to the crushing rollers respectively. The transmission and speed change of the driving force are achieved through the meshing connection between the large gear and the small gear, ensuring that the two crushing rollers can rotate at an appropriate speed and force, thereby effectively crushing the straw.

[0009] Preferably, two crushing rollers are provided, and the two crushing rollers are rotatably connected to the two side walls of the crushing box. The rotatable connection design of the two crushing rollers allows them to rotate simultaneously and cooperate with each other in relative directions to more effectively crush the straw.

[0011] Preferably, a guide plate is provided below the crushing roller, and the guide plate is designed to be in an inclined state. A discharge port is provided at the inclined bottom end of the guide plate, and the discharge port is fixedly installed on the side wall of the crushing box. The inclined design of the guide plate helps the crushed straw to flow naturally to the discharge port, avoiding the accumulation of straw in the crushing box and ensuring the continuity and smoothness of the crushing process.

[0012] Preferably, a slider is fixedly installed on the side wall of the filter, and a slide groove is provided at the contact position between the slider and the inner wall of the dust outlet pipe. The slider and the slide groove are slidably connected. Through the sliding connection between the slider and the slide groove, the filter can be easily removed from the dust outlet pipe and installed, which is convenient for cleaning and maintenance, thereby ensuring the filtering effect of the filter and the stability of long-term use.

The sliding connection design of the dust collecting box makes it simple and convenient to clean and collect the settled dust.

[0015] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0016] 1. Through the setting of the filter, a filter is set inside the dust outlet pipe. The filter can effectively intercept and collect dust and prevent it from being directly discharged into the environment, thereby reducing dust pollution. The sliding disassembly design of the filter composed of a slider and a slide groove makes cleaning and maintenance simple and convenient. When the filter is full of dust or needs to be replaced, the staff can easily slide the filter out of the dust outlet pipe for cleaning or replacement;

[0017] 2. Through the setting of atomizing nozzle and dust collecting box, when the dust is discharged through the dust exhaust pipe, the dust will pass through the atomizing nozzle to produce fine water mist, which will combine with the dust to moisten and settle it, effectively reducing the emission of dust to the outside. The settled dust can be collected by the dust collecting box, avoiding the accumulation of dust inside the dust exhaust pipe. The sliding and pullable dust collecting box design allows the staff to easily take out the dust collecting box and clean it in time. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Working principle of this utility model:

[0031] Refer to the instruction manual Figure 1-3 When using the utility model, first place the cart 1 in a suitable position, ensure that the power connection is normal, the water tank 19 is filled with water, then turn on the power switch, start the drive motor 3, and after the drive motor 3 is started, it drives the large pulley 4 to rotate, and drives the small pulley 5 to rotate through the transmission belt 6, thereby driving the large gear 7 to rotate. The rotation of the large gear 7 will drive the small gear 8 to rotate synchronously, so the two crushing rollers 9 will rotate relatively, and then the straw to be processed will be sent from the feed port 10 into the crushing box 2 through the conveyor belt 11 to achieve continuous feeding, and will be crushed between the two relatively rotating crushing rollers 9. The crushed straw slides along the guide plate 12 under the action of gravity and is finally discharged from the discharge port 13;

[0032] Refer to the instruction manual Figure 4-6When using the utility model, the dust discharge pipe 18 is connected to the external dust collector during the straw crushing process, so that the dust generated in the crushing process is discharged through the dust discharge pipe 14. When the dust passes through the dust discharge pipe 14, it is first intercepted by the filter 15, and larger dust particles are captured by the filter 15. The cleanliness of the filter 15 is checked regularly. If necessary, the filter 15 is slid out through the slider 16 and the slide chute 17 for cleaning. The filtered dust is discharged through the dust discharge pipe 18, and the water in the water tank 19 is sent to the atomizing nozzle 21 through the water pump 20. The atomizing nozzle 21 atomizes the water into fine water mist. The water mist combines with the dust to settle the dust and finally falls into the dust collecting box 22 for centralized collection. The dust amount in the dust collecting box 22 is checked regularly. If there is too much dust, the dust collecting box 22 is slid out for cleaning through the sliding connection.
