Description

Technical Field

[0001] The utility model relates to the field of filtering and impurity removal devices, in particular to a filtering and impurity removal device for feed raw materials. Background Art

[0002] The feed industry, as an indispensable pillar of modern animal husbandry, has extremely high requirements for the purity and quality of feed raw materials. However, impurities such as straw and sand that are common in feed raw materials not only reduce the nutritional value of the feed, but also pose a potential threat to animal health.

[0003] At present, the filtering and impurity removal device for feed raw materials mainly relies on the working principle of the vibrating screen, which screens the feed raw materials through the vibration of the screen. The operating process of this device is usually to put the feed raw materials into the feed inlet, and then the impurities are separated from the pure feed through the shaking of the screen, and finally flow to different collection areas.

[0004] However, when the existing feed raw material filtering and impurity removal device processes a large amount of feed, the particles in the feed may clog the holes of the screen during the vibration of the screen, resulting in a decrease in the filtration efficiency of the screen and may even hinder the entire filtration and impurity removal process, requiring manual cleaning of the screen afterwards. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a device for filtering and removing impurities from feed raw materials to solve the problems mentioned in the above background technology.

[0006] The sieve box is equipped with a feeding hopper on the left side of the top of the sieve box, and a funnel discharge port is provided at the bottom of the sieve box. A buffer assembly is installed at the bottom of the sieve box, and a double-shaft motor is installed at the output end of the double-shaft motor, and a rotating rod is installed on the outer wall of the rotating rod, and a plurality of fan-shaped blocks are sleeved on the outer wall of the rotating rod. A first rotating rod is movably installed inside the sieve box, and the end of the first rotating rod is connected to the rotating rod through a transmission assembly, and two sets of gears are sleeved on the outer wall of the first rotating rod. Second rotating rods are installed on both sides of the inner wall of the sieve box, and a vibrating block is fixed on the end of the second rotating rod, and a half gear is sleeved on the outer wall of the second rotating rod. A first filter screen is provided inside the sieve box, and a second filter screen is installed inside the sieve box. A side discharge port is movably installed on one side of the top of the sieve box, and a main discharge port is provided at the end of the sieve box.

[0007] By adopting the above technical solution, the problem of particles clogging the screen during filtration in the existing raw material filtering and impurity removal device is solved. The fan-shaped block is driven by the rotation of the dual-axis motor to form centrifugal force to cause the entire screen box to vibrate. The output end of the dual-axis motor drives the rotating rod to rotate, so that the first rotating rod connected to the pulley rotates. Since the gear is embedded in the first rotating rod, the half gear engaged with the gear is half engaged with the gear, so that the vibration block on the second rotating rod connected to the half gear moves up. When the half gear is not engaged with the gear, the vibration block will fall down due to gravity, thereby solving the problem of particle clogging of the screen.

[0008] The present invention is further configured such that the transmission assembly includes pulleys fixed to the rotating rod and the end of the first rotating rod, and the two groups of pulleys are connected by a belt.

[0009] By adopting the above technical solution, the dual-axis motor drives the rotating rod to rotate, while the pulley drives the first rotating rod.

[0010] The utility model is further configured such that a bellows is fixed on one side of the side discharge port, and the bellows is fixedly connected to the screen box, thereby reducing other power supply devices.

[0011] By adopting the above technical solution, while the limiting block moves horizontally in the turntable, it is connected to the side discharge port, and the side discharge port is connected to the bellows, which can provide shaking for the side discharge port while achieving horizontal movement of the limiting block.

[0012] The utility model is further configured such that a protrusion is fixed on one side of the pulley, a limiting block is fixed on the bottom of the side discharge port, and a limiting groove is provided inside the limiting block.

[0013] By adopting the above technical solution, by designing a convex block on the turntable, the convex block will drive the limit block to move horizontally while rotating in the groove of the limit block.

[0014] The utility model is further configured such that an inclined baffle is fixed inside the screen box, and the inclined baffle is arranged obliquely.

[0015] By adopting the above technical solution, the design of the inclined baffle provides other inlets and outlets for the first filter screen, which can provide different discharge methods. Setting it to be inclined is a better guide for the discharge port.

[0016] The utility model is further configured such that a cross bar is fixed on one side of the limit block, and a push plate is fixed on the end of the cross bar, and a limit ring is fixed on both sides of the screen box, and the limit ring is sleeved on the outer wall of the cross bar (93).

[0017] By adopting the above technical solution, the cross bar designed on one side of the limit block can limit the fast movement while extending the length. The push plate on the cross bar is used to flatten the raw materials in the collection box, and the limit ring fixes its position.

[0018] The utility model is further configured such that the buffer assembly comprises a telescopic pipe fixed to the bottom of the screen box, and the outer wall of the telescopic pipe is sleeved with a support leg, and the inner wall of the support leg is fixed with a shock-absorbing spring.

[0019] By adopting the above technical solution and arranging shock-absorbing springs on the supporting legs, the screen box can be provided with better shaking, and a telescopic pipe is designed for the shock-absorbing spring to limit the shock-absorbing spring.

[0020] In summary, the present invention has the following beneficial effects:

[0021] 1. The utility model solves the problem of particles clogging the holes of the screen when the screen is shaken by the existing filtering and impurity removal device through the arrangement of a dual-axis motor, a pulley, a first rotating rod, a gear and a half-gear, a vibrating block and a second rotating rod. When the dual-axis motor rotates, the pulley drives the first rotating rod to rotate, and at the same time, the gear installed on the first rotating rod also drives the meshing half-gear. When the half-gear is meshed with the gear, the vibrating block is lifted. When they are not meshed, the vibrating block will hit the second filter due to gravity, thereby solving the problem of particles clogging the holes of the screen.

[0022] 2. The utility model solves the problem of the existing filtering and impurity removal device forming a small hill-shaped pile at the discharge port and causing space waste by setting a dual-axis motor, a protrusion, a pulley, a limiting block, a cross bar and a leveling block. The rotation of the dual-axis motor drives the pulley to rotate, and the protrusion on the pulley drives the limiting block to move horizontally. A push plate is provided at one end of the cross bar connected to the limiting block, and the back-and-forth movement of the push plate solves the problem of leveling the collection box.
