[0001] The utility model belongs to the technical field of screening equipment, and particularly relates to a material screening equipment. Background Art

[0002] A material screening equipment is a mechanical device used to separate solid materials according to particle size. The screening process is generally continuous. When the material passes through the sieve surface, particles smaller than the sieve hole size pass through the sieve holes to become the under-sieve product, while particles larger than the sieve hole size are discharged from the sieve surface and are called the over-sieve product.

[0003] Currently, screening equipment is usually used to separate materials by particle size. When screening materials, due to the continuous jolting of the screening equipment, a large amount of dust will be generated, and thus the dust will float into the surrounding air. There is no mechanism in the prior art to prevent the dust from floating around, so the dust generated during screening will be inhaled by the staff, which will endanger the health of the staff in the long run.

[0004] Therefore, in view of the above technical problems, it is necessary to provide a material screening equipment.

Detailed implementation mode

[0032] In order to enable those skilled in the art to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0033] As Figures 1 to 4 shown, a material sifting device in an embodiment of the present utility model includes a sifting equipment body 1, a covering mechanism 2 and a suction mechanism 3.

[0034] As Figures 1 to 4 shown, a covering mechanism 2 is installed on the sifting equipment body 1. The covering mechanism 2 includes a fixed bin 201. The installation of the fixed bin 201 facilitates the role of support, thus facilitating the sliding of the sliding cover 202 in the fixed bin 201, and at the same time facilitating the installation of other mechanisms on the fixed bin 201.

[0035] Among them, a sliding cover 202 is provided on the sifting equipment body 1. Through the installation of the sliding cover 202, it is convenient to cover the sifting equipment body 1, thereby avoiding the dust generated during the sifting of the sifting equipment body 1 from flying into the external environment.

[0036] Secondly, a first chute matching the sliding cover 202 is dug in the fixed bin 201. The sliding cover 202 is arranged between the fixed bins 201. The digging of the first chute is beneficial for the sliding cover 202 to contract into the fixed bin 201. Therefore, it is convenient to put the material on the sifting equipment body 1 or take out the material from the sifting equipment body 1 after the sifting is completed.

[0037] In addition, a plurality of gears 203 are provided on the fixed bin 201, which is convenient for controlling the contraction and falling of the sliding cover 202, thus facilitating the driving of the movement of the sliding cover 202.

[0038] In addition, a slot matching the gear 203 is drilled in the fixed bin 201. The gear 203 meshes with the sliding cover 202. The drilling of the slot facilitates the penetration of the gear 203 through the fixed bin 201, so that the gear 203 can mesh with the sliding cover 202.

[0039] Secondly, a pair of rotating rods 204 are rotatably installed on the fixed bin 201. The installation of the rotating rods 204 facilitates driving the gear 203 to rotate, and thus the rotation of the gear 203 is beneficial to driving the sliding cover 202 to rise or fall.

[0040] As Figures 1 to 4 shown, the gear 203 is installed on the rotating rod 204, and a synchronous pulley 205 is installed on the rotating rod 204, which is convenient for rotating according to one of the rotating rods 204, so as to facilitate driving the belt 206 to rotate.

[0041] As Figures 2 to 4 shown, a belt 206 is sleeved between a pair of synchronous pulleys 205. The rotation of the belt 206 can drive the other synchronous pulley 205 to rotate, which is beneficial to the synchronous rotation of a pair of rotating rods 204.

[0042] Among them, a threaded rod 207 is rotatably installed between the sliding cover 202 and the screening equipment body 1, which is convenient for firmly fixing the sliding cover 202 and the screening equipment body 1, so as to prevent the sliding cover 202 from jolting up and down during screening of the screening equipment body 1.

[0043] As Figures 2 to 4 shown, a threaded groove matching the threaded rod 207 is drilled in the screening equipment body 1. The drilling of the threaded groove can match the threaded rod 207, so as to firmly fix the sliding cover 202 and the screening equipment body 1.

[0044] In addition, a handle 208 is installed on one of the rotating rods 204. The installation of the handle 208 is beneficial for the staff to rotate, so as to facilitate driving the rotation of one of the rotating rods 204.

[0045] As Figures 1 to 4 shown, a suction mechanism 3 is installed on the screening equipment body 1, and the suction mechanism 3 includes a collection box 301. The installation of the collection box 301 is convenient for collecting dust, so as to prevent the dust from flying around.

[0046] In addition, a sliding bin 302 is slidably installed in the collection box 301. The installation of the sliding bin 302 is beneficial for being drawn out from the collection box 301, so as to facilitate replacing the wet cotton 306 by drawing out the sliding bin 302.

[0047] As Figures 2 to 4As shown, a second chute matching the sliding bin 302 is dug on the collection bin 301. The digging of the second chute facilitates the sliding of the sliding bin 302, so it is convenient to pull out the sliding bin 302 from the collection bin 301.

[0048] Secondly, a pair of blowers 303 are installed on the screening equipment body 1 to facilitate the extraction of the dust generated during screening, so as to facilitate the extraction of the dust into the guiding pipe 305.

[0049] As Figures 1 to 4 shown, a pipe 304 is installed on the blower 303. The pipe 304 penetrates through the sliding cover 202. The installation of the pipe 304 is beneficial to penetrate through the sliding cover 202, so that the blower 303 can suck the dust generated during screening into the blower 303.

[0050] As Figures 1 to 4 shown, a third chute matching the pipe 304 is dug on the sliding cover 202. By digging the third chute, when the sliding cover 202 rises, it will not be restricted by the pipe 304, and the sliding cover 202 can be lifted and lowered smoothly.

[0051] As Figures 1 to 4 shown, a guiding pipe 305 is installed under the blower 303. The guiding pipe 305 penetrates through the collection bin 301, which facilitates the guiding of the dust. Thus, the dust sucked by the blower 303 can fall into the collection bin 301 through the guiding of the guiding pipe 305.

[0052] In addition, a wet cotton 306 is provided in the sliding bin 302. The wet cotton 306 is in a wet state, so that the falling dust can be adsorbed on the wet cotton 306.

[0053] As Figures 1 to 4 shown, a plurality of fixing frames 307 are fixedly installed on the screening equipment body 1. The blower 303 is installed between a pair of fixing frames 307, which facilitates the support of the blower 303 and can ensure the stable installation of the blower 303.

[0054] During specific use, before using the screening equipment body 1 to screen the materials, put the materials into the screening equipment body 1. Then, turn the handle 208 to drive the rotating rod 204 to rotate. Thus, the synchronous wheel 205 will rotate according to one of the rotating rods 204, driving the rotation of the belt 206. Then, the belt 206 transmits the rotational force to drive both rotating rods 204 to rotate. Therefore, the rotation of the rotating rod 204 will drive the gear 203. When the gear 203 rotates, it will drive the sliding cover 202 to slide in the fixed bin 201 and descend. When the sliding cover 202 descends to support on the screening equipment body 1, the sliding cover 202 can be firmly installed on the screening equipment body 1 by using the threaded rod 207.

[0055] Then the screening equipment body 1 is used for screening. During the screening process, the material will generate dust, so the fixed bin 201 and the sliding cover 202 have the function of blocking the dust to prevent the dust from flying into the surrounding environment. Therefore, the fan 303 can be started for exhaust, so that the dust covered by the fixed bin 201 and the sliding cover 202 will be sucked away through the pipe 304, and the dust will fall into the collection box 301 along the guide pipe 305. Since the collection box 301 is provided with wet cotton 306, the wet cotton 306 is in a wet state, so when the dust falls into the collection box 301, it will be adsorbed by the wet cotton 306, so that the dust can be prevented from flying around in the collection box 301. When the wet cotton 306 is replaced, the sliding bin 302 can be pulled out of the collection box 301 for replacement.

[0056] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
