Description

Technical Field

[0001] This utility model relates to the field of material selection technology, specifically to a vibrating feeding tray with adjustable screening size. Background Technology

[0002] A vibrating feeder is a device that uses vibration to move materials in a predetermined direction. During this movement, the material is guided into a designated channel by a selection channel of the target size, thereby achieving the purpose of screening.

[0003] However, existing vibrating feeders typically select a suitable material selection pipe based on the application scenario, allowing materials no larger than the inner diameter of the selection pipe to enter. This means that in actual use, when the material selection size needs to be changed, either a different feeder or the corresponding selection pipe must be selected, which increases the cost and difficulty of the material selection process. Therefore, a vibrating feeder with adjustable screening size is provided to solve the above problems. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this utility model proposes a vibrating feeding plate with adjustable screening size. This solves the problem that when the screening size needs to be changed in the actual use of the existing vibrating feeding plate, either other feeding plates or corresponding screening pipes need to be selected, which increases the cost and difficulty of the screening process.

[0005] A vibrating feeder with adjustable screening size includes a vibrating feeder body. A hopper is provided at the top inner part of the vibrating feeder body. Multiple vibrating motors with preset tilt angles are installed at the bottom of the hopper so that the material in the hopper circulates and moves in a predetermined direction inside the hopper. A discharge pipe is fixedly welded to the side wall of the hopper. The end of the discharge pipe extends into the hopper to naturally form a feed inlet. A baffle is movably installed on the side wall of the hopper. The bottom end of the baffle extends to the surface of the feed inlet. By adjusting the installation height of the baffle on the hopper, the size of the opening of the feed inlet exposed outside the baffle can be changed.

[0006] Preferably, the vibrating feeding tray body includes a base, the vibrating motor is fixedly mounted on the base, and the hopper is fixedly installed on the top of the base, with the bottom end of the hopper shielding the vibrating motor.

[0007] Preferably, the inner top of the hopper is provided with a frustum, so that the material in the hopper naturally moves away from the axis of the frustum along the frustum.

[0008] Preferably, the baffle includes a baffle plate and a fixing screw. The baffle plate has a vertical groove, and the fixing screw passes through the vertical groove and is threadedly connected to the hopper, so that the baffle plate is installed on the inner wall of the hopper.

[0009] Preferably, the baffle further includes a positioning mechanism, which keeps the baffle plate at a preset fixed height.

[0010] Preferably, a washer is movably fitted onto the outer surface of the fixing screw, and the washer abuts against the outer wall of the baffle plate.

[0011] Preferably, the top of the baffle plate is bent inward or outward to naturally form a handle for pulling the baffle plate to move.

[0012] Preferably, the positioning mechanism includes a positioning shaft and a positioning hole. The positioning shaft is fixedly welded to the washer, and the positioning hole is formed on the baffle plate. The positioning shaft and the positioning hole are movably connected.

[0013] Preferably, the positioning mechanism includes a handle and a support pad disposed at the bottom of the handle, wherein the handle is bent outward.

[0014] In summary, this vibrating feeder with adjustable screening size has the following beneficial effects:

[0015] (1) When in use, by loosening the fixing screws, the baffle is pushed up and down by the handle so that the bottom of the baffle blocks the end of the discharge pipe, thereby adjusting the size of the exposed opening at the end of the discharge pipe. Then, the fixing screws are tightened to fix it, which is used to screen materials of different sizes.

[0016] (2) By setting a positioning mechanism on the baffle plate, the height of the baffle plate is fixed by the positioning mechanism, thereby preventing the baffle plate from sliding down naturally under the action of the vibrating motor during use. Attached Figure Description

[0024] The technical solution of this utility model will be more clearly and completely explained below with reference to the accompanying drawings and through the description of the preferred embodiments of this utility model.

[0025] like Figures 1 to 5 As shown, the preferred embodiment of this utility model provides a vibrating feeding tray with adjustable screening size, comprising a vibrating feeding tray body 1, a hopper 12 disposed at the top inner part of the vibrating feeding tray body 1, and a plurality of vibrating motors 14 installed at a preset tilt angle at the bottom of the hopper 12, so that the material in the hopper 12 circulates and moves in a predetermined direction inside the hopper 12; a discharge pipe 2 is fixedly welded to the side wall of the hopper 12, the end of the discharge pipe 2 extending into the hopper 12 to naturally form a feed inlet, and a baffle 3 is movably installed on the side wall of the hopper 12, the bottom end of the baffle 3 extending to the surface of the feed inlet; by adjusting the installation height of the baffle 3 on the hopper 12, the size of the opening of the feed inlet exposed outside the baffle 3 is changed.

[0026] The vibrating feeding plate body 1 includes a base 11, a vibrating motor 14 fixedly mounted on the base 11, and a hopper 12 fixedly mounted on the top of the base 11. The bottom end of the hopper 12 shields the vibrating motor 14, thereby ensuring safe use.

[0027] The inner top of the hopper 12 is provided with a frustum 13, which is high in the middle and low on the periphery, so that the material in the hopper 12 naturally moves away from the axis of the frustum 13 along the frustum 13.

[0028] The baffle 3 includes a baffle plate 31 and a fixing screw 33. The baffle plate 31 has a vertical groove 32. The fixing screw 33 passes through the vertical groove 32 and is threadedly connected to the hopper 12 so that the baffle plate 31 is installed on the inner wall of the hopper 12.

[0029] A washer 34 is movably fitted onto the outer surface of the fixing screw 33. The washer 34 abuts against the outer wall of the baffle plate 31, thereby increasing the frictional resistance.

[0030] The top of the baffle plate 31 is bent inward or outward to naturally form a handle 35 for pulling the baffle plate 31 to move. When the handle 35 faces outward, it is convenient to operate and move by hand. When the handle 35 faces inward, it can effectively prevent the baffle plate 31 from moving due to accidental contact with the handle 35 when adding material.

[0031] Working principle: When the device is in use, the material is put into the hopper 12. At this time, the material naturally falls towards the outer ring of the hopper 12 under the action of the frustum 13. Then, by starting the vibration motor 14, the material circulates in the same direction inside the hopper 12 under the action of multiple vibration motors 14. When the material passes through the discharge pipe 2, the material that is not larger than the inner diameter of the discharge pipe 2 enters the discharge pipe 2 and is discharged outward.

[0032] Meanwhile, during use, by loosening the fixing screw 33, the baffle plate 31 is pushed up and down by the handle 35, so that the bottom of the baffle plate 31 blocks the end of the discharge pipe 2, thereby adjusting the size of the exposed opening at the end of the discharge pipe 2. Then, the fixing screw 33 is tightened to fix it, which is used to screen materials of different sizes.

[0033] Based on the above solution, the baffle 3 also includes a positioning mechanism, which keeps the baffle 31 at a preset fixed height.

[0034] Two other optional embodiments included in this application are:

[0035] The positioning mechanism includes a positioning shaft 36 and a positioning hole 37. The positioning shaft 36 is fixedly welded to the washer 34, and the positioning hole 37 is opened on the baffle plate 31. The positioning shaft 36 and the positioning hole 37 are movably inserted into each other. In use, by loosening the fixing screw 33, and then moving the washer 34 away from the baffle plate 31, the positioning shaft 36 is separated from the positioning hole 37. Then the baffle plate 31 is moved up and down so that the positioning shaft 36 is aligned with the other positioning hole 37. Then the fixing screw 33 is tightened again. In this way, when adjusting the height of the baffle plate 31, the positioning shaft 36 is inserted into the positioning hole 37 for positioning, which prevents the baffle plate 31 from sliding down naturally under the action of the vibration motor 14.

[0036] II. The positioning mechanism includes a handle 35 and a support pad 38 disposed at the bottom of the handle 35. The handle 35 is bent outward. After adjusting the height of the baffle plate 31, an appropriate number of support pads 38 are inserted between the handle 35 and the top of the hopper 12, so that the baffle plate 31 will not slide down naturally under the action of the vibration motor 14.

[0037] The above-described specific embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Various modifications, substitutions, and improvements made by those skilled in the art to the technical solutions of the present invention based on the provided description and drawings, without departing from the design concept and spirit of the present invention, should all fall within the scope of protection of the present invention. The scope of protection of the present invention is determined by the claims.
