Abstract
Description
Technical Field
[0001] This application relates to the field of soil remediation technology, specifically to a crushing and screening roller device. Background Technology
[0002] Soil remediation refers to the treatment of contaminated soil through physical, chemical, or biological means to remove or reduce the concentration of harmful substances, restoring the soil to a state suitable for plant growth and ecosystem health. The soil remediation process requires breaking down the contaminated soil into smaller pieces, thereby increasing the contact area between the soil and remediation agents (such as chemicals and solidifying agents), improving remediation efficiency. Breaking also helps to break up aggregates in the soil, increasing soil permeability and infiltration.
[0003] Soil is fed between motor-driven crushing rollers, where large clumps of soil are crushed into smaller pieces by rotation. A screen placed at the bottom of the crushing rollers removes impurities from the soil. During the crushing process, a large amount of dust is generated because the soil is contaminated. If this dust containing pollutants is inhaled, it can affect the health of people. Utility Model Content
[0004] The purpose of this application is to provide a crushing and screening roller device to solve the problem mentioned in the background art that during the operation of the crushing roller, a large amount of dust is generated and diffused because the soil is contaminated. This dust containing pollutants can affect the health of people if inhaled.
[0005] To achieve the above objectives, this application provides the following technical solution: a crushing and screening roller device, comprising: an operating box, a crushing component, a dust suppression mechanism, a tossing mechanism, and a screening screen. The main body of the crushing and screening equipment includes an operating box, a crushing component disposed inside the operating box, and a screening screen disposed inside the operating box below the crushing component.

[0009] Preferably, the actuating mechanism includes a drive motor fixed to the top of the sealed protective box, and a connecting shaft is provided on the output end of the drive motor, and the connecting shaft is engaged and fixed inside the bearing of the sealed protective box.
[0010] By adopting the above technical solution, it is possible to provide a stable structure connected to the output end for rotating operation.
[0011] Preferably, the actuating mechanism further includes an eccentric wheel fixed on the connecting shaft at the output end of the drive motor.

[0018] By adopting the above technical solution, the elastic force of the device itself can be used to squeeze and push the connecting block that is attached to one end to achieve reset.
[0019] In summary, this application has the following beneficial effects: by incorporating a dust suppression mechanism and a dispersing mechanism, the dust suppression mechanism continuously absorbs the diffused dust during the dust diffusion process, thereby effectively reducing the probability of personnel breathing in dust containing pollutants.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0027] The following is in conjunction with the appendix Figure 1-5 The embodiments of this application will be described in further detail.
[0028] Example 1
[0029] Please see Figures 1-5This embodiment provides a technical solution: a crushing and screening roller device, including: an operating box 1, a crushing component 2, a dust suppression mechanism 3, a tossing mechanism 4, and a screening screen 5;
[0030] The main body of the crushing and screening equipment includes an operating box 1, a crushing component 2 set inside the operating box 1, and a screening screen 5 set inside the operating box 1 and below the crushing component 2. Three sets of through holes are opened on the outer wall of the feed inlet of the operating box 1. The crushing component 2 is driven by a motor to rotate the crushing roller body at the output end, thereby crushing the lumpy soil passing above. The above is the prior art, and will not be described in detail below.
[0031] The dust suppression mechanism 3 is located inside the three sets of through holes in the operating box 1. The dust suppression mechanism 3 includes a vacuum cleaner body 301 fixed to the outer wall of the operating box 1. The vacuum cleaner body 301 is a cleaning tool that uses an electric motor to generate negative air pressure to suck up dust. The above is the prior art and will not be described in detail below. A sealed protective box 302 is located on the outer wall of the three sets of through holes in the operating box 1. A through hole is opened in the center of the top of the sealed protective box 302, and a bearing is installed inside the through hole of the sealed protective box 302. The sealed protective box 302 is connected to the outer wall of the exhaust port of the vacuum cleaner body 301 through a hose. A filter suction pipe 303 is horizontally slidably connected inside the three sets of through holes in the operating box 1. A filter screen is integrally formed inside the filter suction pipe 303. A fixing plate 304 and a plug block 305 welded to one end of the outer wall of the fixing plate 304 are located on the outer wall of the three sets of through holes in the operating box 1. A toggle mechanism 4 is located inside the sealed protective box 302.
[0032] Soil is fed into the operating box 1 through the feed inlet at the top of the operating box 1. At this time, the crushing component 2 is started. The crushing roller body of the crushing component 2 is driven by the motor to rotate, thereby crushing the clumps of soil passing above. After the soil is crushed, the qualified soil particles are screened through the screening screen 5 below and discharged through the discharge port at the bottom of the operating box 1. When the soil is crushed by the crushing component 2, the diffuse dust generated can be collected by the dust suppression mechanism 3. The agitator 4 can clean the dust suppression mechanism 3 in time when it receives splashed soil particles that block it.
[0033] When dust accumulates at the feed inlet of the operating housing 1, the vacuum cleaner body 301 is activated. Since the vacuum cleaner body 301 is connected to the sealed protective box 302 via a flexible hose, and the interior of the sealed protective box 302 is connected to the feed inlet of the operating housing 1 via a filter suction pipe 303, the vacuum cleaner body 301 can quickly absorb the dust at the feed inlet of the operating housing 1 through the filter suction pipe 303. When small, clumps of soil become stuck in the filter mesh of the filter suction pipe 303, the filter suction pipe 303 is slid through the holes in the operating housing 1. During this movement, the filter suction pipe 303 aligns its filter mesh with the insertion block 305 of the fixing plate 304, allowing the insertion block 305 to be inserted into the filter mesh of the filter suction pipe 303 for cleaning.
[0034] Example 2
[0035] Please see Figures 1-5 This embodiment provides a technical solution: a crushing and screening roller device, including: a drive motor 401, an eccentric wheel 402, a connecting block 403, a "U"-shaped rod 404, a positioning block 405, and a spring 406;
[0036] The actuating mechanism 4 includes a drive motor 401 fixed on the top of the sealed protective box 302, a connecting shaft on the output end of the drive motor 401, and the connecting shaft is engaged and fixed inside the bearing of the sealed protective box 302. An eccentric wheel 402 is fixed on the connecting shaft at the output end of the drive motor 401, and a connecting block 403 is welded to the outer wall of the filter dust collection pipe 303. There are two sets of connecting blocks 403.
[0037] The "U"-shaped rod 404 is welded to the outer wall of the two sets of connecting blocks 403 and the positioning block 405 is fixed to the outer wall of the operating box 1. The two ends of the "U"-shaped rod 404 are slidably disposed inside the positioning block 405. The springs 406 are sleeved on the two ends of the "U"-shaped rod 404, and the two ends of the springs 406 are respectively attached to the outer walls of the connecting block 403 and the positioning block 405.
[0038] When it is necessary to frequently clean and clog the filter mesh of the dust collection duct 303, the drive motor 401 is started. The drive motor 401 drives the eccentric wheel 402 connected to the bottom output end to rotate. When the eccentric wheel 402 rotates, it drives the "U"-shaped rod 404 on one side to move horizontally inside the positioning block 405. At this time, the "U"-shaped rod 404 is connected to multiple sets of dust collection ducts 303 through the connecting block 403, so that it moves together with the "U"-shaped rod 404, so that the dust collection duct 303 can automatically contact the insertion block 305. When the eccentric wheel 402 rotates to the point where it no longer contacts the "U"-shaped rod 404, the connecting block 403 is pushed by the spring 406 to return to its original position. At this time, the insertion block 305 is no longer in the mesh of the dust collection duct 303, thus providing good air permeability to the mesh of the dust collection duct 303.
[0039] The implementation principle of the crushing and screening roller device of this application is as follows:
[0040] First, the soil is fed into the operating box 1 through the feed port at the top of the operating box 1. At this time, the crushing component 2 is started. The crushing roller body of the crushing component 2 is driven by the motor to rotate, thereby crushing the clumps of soil passing above. After the soil is crushed, the soil particles of qualified size are screened through the screening screen 5 below and discharged through the discharge port at the bottom of the operating box 1. When the soil is crushed by the crushing component 2, the diffuse dust generated can be collected by the dust suppression mechanism 3. The agitator 4 can clean the dust suppression mechanism 3 in time when it receives splashed soil particles that block it.
[0041] Secondly, when dust accumulates at the feed inlet of the operating box 1, the vacuum cleaner body 301 is activated. Since the vacuum cleaner body 301 is connected to the sealed protective box 302 via a flexible hose, and the interior of the sealed protective box 302 is connected to the feed inlet of the operating box 1 via a filter suction pipe 303, the vacuum cleaner body 301 can quickly absorb the dust at the feed inlet of the operating box 1 through the filter suction pipe 303. When small, clumps of soil become stuck in the filter mesh of the filter suction pipe 303, the filter suction pipe 303 is slid through the holes in the operating box 1. During this movement, the filter suction pipe 303 aligns its filter mesh with the insertion block 305 of the fixing plate 304, allowing the insertion block 305 to be inserted into the filter mesh of the filter suction pipe 303 for cleaning.
[0042] Finally, when it is necessary to frequently clean and clog the filter mesh of the dust collection duct 303, the drive motor 401 is started. The drive motor 401 will drive the eccentric wheel 402 connected to the bottom output end to rotate. When the eccentric wheel 402 rotates, it will drive the "U"-shaped rod 404 on one side to move horizontally inside the positioning block 405. At this time, the "U"-shaped rod 404 is connected to multiple sets of dust collection ducts 303 through the connecting block 403, so that it will move together with the "U"-shaped rod 404, so that the dust collection duct 303 can automatically contact the insertion block 305. When the eccentric wheel 402 rotates to no longer contact the "U"-shaped rod 404, the connecting block 403 is pushed by the spring 406 to return to its original position. At this time, the insertion block 305 is no longer in the mesh of the dust collection duct 303, thus providing good air permeability to the mesh of the dust collection duct 303.
[0043] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
