Technical Field

[0001] The utility model relates to the technical field of feed screening, in particular to a mechanical feed screening machine capable of removing dust. Background Art

[0002] When producing and processing feed, a feed mechanical screening machine (such as a drum screening machine) is usually used to screen and remove impurities in the feed to ensure the product quality of the feed. At the same time, considering that dust will be generated during the feed screening process, existing feed mechanical screening machines (such as drum screening machines) generally have a sealed dust cover installed on the outside of the drum screen.

[0003] The feed mechanical screening machines on the market (such as drum screening machines) use a pre-installed dust cover structure to achieve the purpose of dust blocking and dust removal. Considering that most dust covers adopt an integrated semicircular structure that is compatible with the drum screen, and are fixedly connected to the screening machine frame, the covering effect of the integrated dust cover is not conducive to the regular maintenance and sieve hole cleaning operations of the drum screen in the later stage. The operation of repeatedly disassembling the dust cover is also time-consuming and laborious. Therefore, a feed mechanical screening machine with dust removal is proposed to address the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a feed mechanical screening machine capable of removing dust, so as to solve the problem in the above-mentioned background technology that when the feed mechanical screening machine is in use, the integrated structure of the dust removal cover structure makes it inconvenient to perform regular maintenance and sieve hole cleaning operations on the drum screen at a later stage.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] Preferably, a center bracket is fixedly connected to the middle position of the inner side of the drum screen body, a front support plate is fixedly connected to the front end of the screening frame, and a second motor is fixedly installed at the middle position of the top end of the front support plate, and the output end of the second motor is connected to the middle of the center bracket.

[0008] Preferably, the bottom end of the screening frame is connected to a lower hopper, and a supporting wheel is rotatably mounted at a lower position on one side of the inner side of the screening frame, and the supporting wheel is arranged at a lower left position of the drum screen body.

[0009] Preferably, the right baffle cover is symmetrically arranged with the left baffle cover along the vertical center axis of the screening frame as the axis of symmetry, and the front and rear ends of the inner sides of the right baffle cover and the left baffle cover are respectively fixedly connected with auxiliary cover rings, the inner side surfaces of the auxiliary cover rings are bonded with rubber strips, and the outer shape of the rubber strips is arranged in an arc-shaped structure, and one end of the right baffle cover and the left baffle cover are respectively fixedly connected with magnetic blocks.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-5 , the utility model provides a technical solution:

[0021] A mechanical feed screening machine capable of removing dust comprises a screening frame 1, a drum screen body 2 is rotatably mounted at the middle position of the top of the screening frame 1, a right baffle 3 is provided on the upper right exterior of the drum screen body 2, and a left baffle 4 is provided on the upper left exterior of the drum screen body 2, side brackets 11 are fixedly connected to both sides of the screening frame 1, side vertical plates 7 are fixedly connected to the front and rear ends of the top of the side bracket 11, and a rotating shaft 8 is rotatably connected to the middle position of the side vertical plate 7, a transmission gear 9 is sleeved on the outside of the rotating shaft 8, and a driving gear 10 is meshedly connected to the lower position of the transmission gear 9, a rotating block 6 is fixedly connected to the rear end of the rotating shaft 8, and an auxiliary bracket 5 is fixedly connected to the side position of the side bracket 11 away from the screening frame 1.

[0022] like Figure 1 and Figure 2 As shown, a center bracket 17 is fixedly connected to the middle position of the inner side of the drum screen body 2, a front support plate 18 is fixedly connected to the front end of the screening frame 1, and a second motor 19 is fixedly installed at the middle position of the top end of the front support plate 18, and the output end of the second motor 19 is connected to the middle of the center bracket 17. When the equipment is started and assembled, the setting of the center bracket 17 mainly plays a role in assisting the drum screen body 2 to quickly connect to the drum screen body 2; a lower hopper 20 is connected to the bottom end of the screening frame 1, and a supporting wheel 13 is rotatably installed at the lower position of one side of the interior of the screening frame 1, and the supporting wheel 13 is arranged at the lower left position of the drum screen body 2. When the drum screen body 2 realizes the rotation operation, a group of supporting wheels 13 installed at the lower positions on both sides of the interior of the screening frame 1 will provide auxiliary support for it.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the right baffle 3 is symmetrically arranged with the left baffle 4 along the vertical center axis of the screening frame 1 as the symmetry axis, and the front and rear ends of the inner sides of the right baffle 3 and the left baffle 4 are respectively fixedly connected with auxiliary cover rings 15, and the inner side of the auxiliary cover ring 15 is bonded with a rubber strip 16, and the outer shape of the rubber strip 16 is arranged in an arc-shaped structure. One end of the right baffle 3 and the left baffle 4 is respectively fixedly connected with a magnetic block 14. After completing the maintenance and sieve hole cleaning operations, the right baffle 3 and the left baffle 4 driven by the gear will be reset and flipped respectively, and cover the drum screen body 2, so that it can perform screening work in a relatively sealed and dust-proof environment. At the same time, as the right baffle 3 and the left baffle 4 are reset and flipped and docked, a group of magnetic blocks 14 will be magnetically connected together, thereby assisting in limiting the docking between the right baffle 3 and the left baffle 4.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the auxiliary bracket 5 is arranged in an "L"-shaped structure, and the height of the auxiliary bracket 5 is greater than the height of the side bracket 11.

The driving gear 10 is connected through a transmission gear 9, a rotating shaft 8 and a rotating block 6. The two groups of rotating blocks 6 are respectively fixedly connected to the right baffle 3 and the left baffle 4. After the right baffle 3 and the left baffle 4 are respectively flipped outward and opened in the direction away from the drum screen body 2, the auxiliary bracket 5 against the bottom of the right baffle 3 and the left baffle 4 will provide auxiliary support thereto.

[0025] Working process: when it is necessary to use the mechanical screening machine for feed with dust removal, as an appropriate amount of feed is accurately fed into the interior of the drum screen body 2, when the dust removal structure composed of the right baffle 3 and the left baffle 4 is in a closed state (so that the equipment can block and remove the dust generated during feed screening), the second motor 19 will start to rotate the drum screen body 2 through the central bracket 17, so that the equipment can screen and sieve the feed and the impurities mixed inside through the drum screen body 2 with multiple sieve holes on the outer surface. When it is necessary to perform regular maintenance and sieve hole cleaning on the drum screen component, under the connection of the side stand 7 and the side bracket 11, the two groups of first motors 12 will rotate with the transmission gear 9 through the driving gear 10, so that the right baffle 3 and the left baffle 4 can be turned outward along the center point of the rotating shaft 8 respectively, and supported by the auxiliary bracket 5, the entire dust cover structure can be quickly unfolded, so that the staff can perform convenient maintenance and sieve hole cleaning operations on the drum screen later.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
