Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of biomass fuel preparation, in particular to a tobacco stalk automatic feeding type straw crushing device. BACKGROUND

[0002] Tobacco stalk is the stem part left after tobacco plant is harvested, which is bulky and belongs to a high-quality biomass raw material. In the prior art, a crushing device is usually used to crush the tobacco stalk, and then the crushed tobacco stalk is extruded to form a granular biomass fuel. Dust is inevitably generated during the crushing process. In order to reduce dust pollution, a dust removal device is usually provided in the crushing device to suppress dust. For example, the document with publication number CN218353359U crushes straw through a crusher, and the crushed straw falls on a conveyor, which conveys the crushed straw into a collection box to collect the crushed straw, thereby avoiding the situation that the crushed straw is directly discharged to cause dust to be scattered in a large area and harm the health of nearby workers. Meanwhile, a fan is used to suck and filter the dust generated during the crushing process of the tobacco stalk through a filter screen. However, during the crushing process, the suction force of the fan is hindered by the dust accumulated on the surface of the filter screen, which causes the suction force of the fan to gradually decrease with the extension of the use time. This reduces the adsorption effect and range of the dust, and causes the dust far away from the fan to be discharged together with the crushed material. This part of dust is still easy to be blown up by wind, vibration and other external factors when it is discharged to the outside, which still causes dust pollution. SUMMARY

[0020] As Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the processing mechanism 500 comprises an electric rolling assembly 510 fixedly connected to one end of the crusher 400, one end of the electric rolling assembly 510 penetrates into the crusher 400 and is rotationally connected with the crusher 400, the surface of the electric rolling assembly 510 is embeddedly installed with a ring-shaped distribution of coarse filter screens 520, the surface of the electric rolling assembly 510 is fixedly connected with a ring-shaped distribution of push rods 530 staggered with the coarse filter screens 520, the inside of the electric rolling assembly 510 is rotationally connected with a three-pass filter assembly 540 fixedly connected with the crusher 400, one end of the three-pass filter assembly 540 is fixedly connected and communicated with an air pump 550; the processing mechanism 500 further comprises a cross rod 560 fixedly connected to the inside of the crusher 400, the bottom of the cross rod 560 is fixedly connected with evenly distributed and staggered with the push rods 530 unblocking rods 570, the unblocking rods 570 can scrape off the materials intercepted by the push rods 530 when the push rods 530 rotate, which can reduce the probability of material residues on the surface of the push rods 530 or the electric rolling assembly 510, to ensure the smoothness of the coarse filter screens 520; When the crusher 400 grinds the materials, the electric rolling assembly 510 simultaneously drives the rotation of the push rods 530 and the coarse filter screens 520, the push rods 530 can push the falling materials to all directions, which can avoid the accumulation of ground materials, reduce the phenomenon of "bridge" or blockage of the discharge end of the crusher 400, improve the flowability and filling characteristics of the materials, and achieve the effect of convenient discharge, while the air pump 550 rapidly sucks the air inside the crusher 400 through the three-pass filter assembly 540, the airflow wraps the dust through the coarse filter screens 520 and enters the three-pass filter assembly 540 for filtration, while the coarse filter screens 520 can effectively intercept the materials guided by the airflow and enter the three-pass filter assembly 540, which not only can reduce the blockage of the three-pass filter assembly 540 due to the filling of materials, but also can reduce the waste of materials.

[0021] As Figure 2 , Figure 3 and Figure 4As shown, the electric rolling assembly 510 includes a servo motor 511 fixedly connected to one end of the crusher 400, the end of the output shaft of the servo motor 511 is fixedly connected with a cylinder 512, one end of the cylinder 512 penetrates out of the crusher 400 and is rotationally connected with the crusher 400, the cylinder 512 is arranged directly above the discharge end of the crusher 400, the surface of the cylinder 512 is provided with annularly distributed mounting ports 513, the coarse filter screen 520 is fixedly connected to the inside of the mounting ports 513, the lever 530 is fixedly connected to the surface of the cylinder 512, and the lever 530 is staggered with the mounting ports 513, the hopper 541 is rotationally connected to the inside of the cylinder 512; the inside of the cylinder 512 is rotationally connected with a blocking circular frame 514 which is staggered with the mounting ports 513, and the tee joint 542 is fixedly connected to the inside of the blocking circular frame 514, which can block the air in and outside the crusher 400 from communicating through the gap between the tee joint 542 and the cylinder 512, not only can reduce the probability of the dust inside the crusher 400 polluting the outside, but also can ensure the suction effect of the dust inside the crusher 400, thereby ensuring the removal rate of the dust inside the crusher 400. When the user starts the servo motor 511, the servo motor 511 drives the cylinder 512 to rotate, and the cylinder 512 simultaneously drives the lever 530 and the coarse filter screen 520 to rotate, which not only can make the lever 530 rotate to disperse the falling materials, but also can cyclically replace the coarse filter screen 520 at the inlet of the three-pass filter assembly 540, so as to reduce the resistance of the airflow carrying dust into the three-pass filter assembly 540.

[0022] As shown in the drawings, Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the three-way filtering assembly 540 includes a hopper 541 rotatably connected to the inner side of the motorized rolling assembly 510, one end of the hopper 541 is fixedly connected and communicated with a three-way pipe 542, the surface of the three-way pipe 542 is fixedly connected with a processing box 543 fixedly connected with the crusher 400, one end of the processing box 543 is provided with two installation chambers 544 respectively communicated with one of the openings of the three-way pipe 542, the inside of the installation chamber 544 is inserted with a net box 545 arranged directly below one of the openings of the three-way pipe 542, the mesh diameter of the net box 545 is smaller than that of the coarse filter screen 520, the bottom of the processing box 543 is fixedly connected with two air guide pipes 546 respectively communicated with the two installation chambers 544, the two air guide pipes 546 are fixedly connected and communicated with a three-way electromagnetic valve 547, one end of the three-way electromagnetic valve 547 is fixedly connected and communicated with a wind speed controller 548, and the wind speed controller 548 is fixedly connected to the air inlet end of an air pump 550; the vertical sectional shape of the hopper 541 is fan-shaped, and the opening of the hopper 541 faces upward, which can limit the air pump 550 to only suck the dust inside the crusher 400 upward, so as to reduce the influence on the cleaning of the rod 530 and the surface material of the cylinder 512; the cross-sectional shape of the inner bottom wall of the hopper 541 is ramp-shaped, and the lowest part of the inner bottom wall of the hopper 541 is communicated with the three-way pipe 542, which can guide the dust into the three-way pipe 542, so as to reduce the probability of dust remaining inside the hopper 541; the inner top wall of the installation chamber 544 is rotatably connected with a blocking plate 549, the top of the blocking plate 549 blocks the opening communicated between the three-way pipe 542 and the installation chamber 544, and the bottom of the blocking plate 549 is fixedly connected with a spring 5410 fixedly connected with the installation chamber 544, when the airflow inside the three-way pipe 542 actively pushes against the top of the blocking plate 549, the blocking plate 549 can press down the spring 5410, so that the airflow can easily push against the blocking plate 549 and enter the installation chamber 544; when the three-way electromagnetic valve 547 switches the airflow to guide to another installation chamber 544, at this time, the spring 5410 in the original installation chamber 544 drives the blocking plate 549 to quickly block the adjacent opening of the three-way pipe 542, which can avoid that the airflow carrying dust enters the unblocked installation chamber 544 during the process of the user cleaning the dust inside the adjacent net box 545, thereby reducing the probability of dust polluting the outside world; one end of the net box 545 is provided with a transparent observation window 5411, which can facilitate the user to observe the dust accumulation or flow condition inside the net box 545, so as to facilitate the user to clean the net box 545; one end of the net box 545 is fixedly connected with a handle 5412, which can reduce the difficulty of the user to put or take the net box 545; When the user starts the air pump 550, the air pump 550 sucks the air flow entraining dust into the hopper 541, the hopper 541 guides the air flow entraining dust into the three-way pipe 542, the three-way pipe 542 guides the air flow entraining dust into the corresponding installation chamber 544, the mesh box 545 intercepts the dust entrained in the air flow, so that the clean air flow passes through the corresponding air guide pipe 546, the three-way electromagnetic valve 547 and the air pump 550 outside the external environment in turn, in this process, the wind speed controller 548 monitors the air flow value derived from the three-way electromagnetic valve 547 in real time, and compares the monitoring data with the preset lower limit data of the wind speed, if the monitoring data is less than the preset lower limit data of the wind speed, it indicates that the dust in the mesh box 545 accumulates to the preset condition that needs to be cleaned, the wind speed controller 548 controls the three-way electromagnetic valve 547 to communicate the air pump 550 with another air guide pipe 546 according to the switching instruction preset in it, at this time the air flow is sucked into another installation chamber 544 for processing, so that another unused mesh box 545 can filter the dust in the passing air flow, in this process, the worker can clean the mesh box 545 that needs to be cleaned without stopping, which not only can ensure the removal rate of the dust in the crusher 400, but also can ensure that the whole straw crushing process can proceed normally, thereby ensuring the efficiency of the straw crushing.
