Agricultural vibrating screen is a kind of vibrating screening equipment developed for agricultural field, and is mainly applied to the processing and production process of agricultural products. It can classify and process raw agricultural products according to particle size by vibration force.

[0003] However, in the existing technology, the current production of vibrating screen has the following problems in the design of bran removing system:

[0004] (1) The single bran removing effect of the existing vibrating screen is poor, especially the fine or adhered bran particles on the surface of the grain. It is more difficult to screen, and the quality and taste of the grain with poor screening effect will decrease linearly, which will affect the quality of rice. And when the existing vibrating screen is used for screening a large amount of grain, the waterfall surface generated by the vibrating screen device for bran removing is small, and the material conveying of the track machine is also small, which will affect the transportation efficiency.

[0005] (2) When the traditional vibrating screen is used for dust treatment, the vibrating screen top cover is usually directly communicated with the subsequent dust suction system to adsorb dust, but this way will also suck some bran with light quality into the dust suction system, and the adsorption of bran will cause the blockage of dust suction filter element, which will affect the subsequent dust suction effect.

Obviously, the embodiments of the present invention described are only part of the embodiments, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] In the description of the present invention, it should be noted that the terms "upper", "lower", "side by side", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description clearly, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limiting the present invention.

[0044] like Figures 1-5 As shown, a vibrating screen high-efficiency bran removal device includes: an outer shell 1, a feed port 2, a discharge port 3, a drive motor 4, an auger 5, a ventilation duct 6, a parallel shackle 7, a dust suction top cover 8, a top cover dust discharge port 9, a dust removal duct 10, and a centrifugal fan 11. The outer shell 1 is rectangular as a whole, and is provided with a accommodating space inside. The accommodating space is used to place the auger. The feed port 2 is placed on the outer shell 1. In order to make the feed port adapt to the height of most vibrating screen equipment and ensure that the size of the feed port remains unchanged, a rotating rod is provided on the outer shell 1. The feed port 2 is rotatably connected to the outer shell 1 through the rotating rod. When the feed hopper 2 rotates, the height of the feed inlet will change accordingly. Therefore, the material receiving part of the feed port 2 is rectangular, and the rotating part is arc-shaped. The corresponding angle and height can be set in advance before pouring the material.

[0045] Preferably, Figure 5 As shown, in order to process short rods, the drive motor 4 is arranged on the side of the outer shell 1 to provide kinetic energy for the auger 5; the auger 5 is placed in the accommodating space of the outer shell 1, and the rotating blades of the auger 5 are installed at the output end of the drive motor and connected to the inner wall of the outer shell 1. The auger 5 rotates through the kinetic energy driven by the drive motor 4, and the introduced material can be chopped into some straws.

[0046] In this embodiment, Figures 3-5As shown, in order to be able to remove a large amount of bran and not produce pollution, the ventilation pipe 6 is located above the outer shell 1, the air inlet of the ventilation pipe 6 is connected with the outer shell 1, the ventilation pipe 6 is used to transport bran for dust removal and the ventilation pipe 6 is communicated with the parallel shaker 7, the parallel shaker 7 has seven shakers in parallel, and the three air inlets are arranged in parallel, and the parallel shaker 7 is symmetrically arranged in two rows, and the last one is arranged in the center of the two rows, and the air inlet of the parallel shaker 7 is connected with the ventilation pipe 6, and the parallel shaker 7 can remove a large amount of bran; The dust suction top cover 8 is horizontally arranged on the top of the parallel shaker 7, the dust suction top cover 8 is fixedly arranged on the parallel shaker 7, and the bottom of the dust suction top cover 8 is communicated with the dust removal port of the parallel shaker 7, the dust suction port of the dust removal air duct 10 is communicated with the dust removal port of the dust suction top cover 8, that is, the seven shakers are connected through the dust suction top cover 8, and the dust is discharged through the dust removal port and introduced into the dust removal air duct 10 through the dust removal port. The centrifugal fan 11 pours into the subsequent processing step for purification treatment.

[0047] It is worth mentioning that, due to the large volume of the parallel shaker, the shaker bran discharge port is more, and due to the height of the walking support 13 is higher than the height of the general vibrating screen discharge port, the height difference and the large equipment processing capacity will produce a large waterfall surface, which is convenient for material conveying.

[0048] Preferably, the walking support 13 is arranged at the bottom of the parallel shaker 7, and a circular hole corresponding to the discharge port of the parallel shaker 7 is arranged at the top of the walking support 13, so that the walking support 13 is connected with the parallel shaker 7 through the circular hole, which is convenient for supporting and pushing the equipment.

[0049] It needs to be explained that the utility model discloses a high -efficient bran removing device of vibrating screen. When using, first, material is poured into the vibrating screen hopper 19, then the vibrating screen motor is started, and the vibrating screen body 15 is driven by the motor vibration, and the material is screened. The screened material is poured into the feed inlet 2 through the vibrating screen discharge hopper 14, enters the inside of the shell body 1, and the driving motor 4 and the centrifugal fan 11 are started, the driving motor 4 drives the inside of the shell body 1 to rotate, if the poured material is larger short stem, then the short stem is crushed by the rotation of the auger 5, and the bran mixed in the short stem is sucked into the ventilation duct 6 through the filter screen 12, if the poured material is smaller grain, then the rotation of the auger drives the smaller grain to move, so that the bran mixed in the grain is also stirred with the grain, the bran is sucked by the suction airflow generated by the centrifugal fan 11, the bran is screened out of the grain particles through the filter screen 12, and then is sucked into the ventilation duct 6. At this time, the bran after the bran is removed is poured out through the discharge port 3, and the bran is poured into the parallel sandkong 7 through the ventilation duct 6. The parallel sandkong 7 operates to separate the bran and the dust mixed therein, the bran after dust removal is poured out from the discharge port of the parallel sandkong 7, and the lighter dust after the bran is removed is guided into the dust suction top cover 8 through the dust removal top cover 8. The dust suction top cover 8 guides the dust into the dust removal air duct 9, and the dust removal air duct 9 is communicated with the centrifugal fan 11, so that the dust after the bran is removed is guided into the centrifugal fan 11 for purification, and finally is poured into the subsequent dust removal system by the centrifugal fan 11. In this way, after the bran is removed, the bran discharged does not have a large dust phenomenon. Thus, the bran removal work flow is completed.

[0050] It is worth noting that: the whole device can realize the control of the motor through the total control button. Since the control button matching device is a commonly used device, it belongs to the existing mature technology, and the electrical connection relationship and the specific circuit structure are not described here.
