Description

Technical Field

[0001] This utility model belongs to the field of lime powder processing technology, and specifically relates to a feeding device for a hoist. Background Technology

[0002] A feeding device for an elevator is a specialized device designed to efficiently and accurately feed materials into the elevator. This device is typically used in conjunction with bucket elevators, screw conveyors, and other types of lifting equipment to achieve continuous material conveying and lifting. The design of the feeding device must consider factors such as material characteristics (e.g., particle size, density, flowability), production efficiency, and the operating environment to ensure that materials enter the elevator smoothly and continuously, avoiding blockages and waste.

[0003] Existing elevator feeding devices use valves to allow lime powder inside the storage tank to fall onto the elevator's lifting shell or conveyor belt under gravity through the discharge shell, thus feeding the elevator. However, since elevators vary in height but have fixed discharge shell dimensions, lime powder inevitably falls into the lower feeding area of ​​the elevator, causing dust to fly around. This not only wastes lime powder but also pollutes the working environment and affects the health of operators. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a feeding device for a hoist. The size of the discharge shell can be flexibly adjusted according to hoists of different heights, ensuring that the discharge shell is kept close to the feeding area of ​​the hoist. This avoids dust spreading during lime powder feeding, prevents lime powder waste, improves the working environment, and protects the health of operators.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a feeding device for a hoist includes a storage box, a discharge shell is provided in the discharge port at the lower end of the storage box, a sliding shell is slidably arranged inside the discharge shell, a chute frame is provided on the rear side of the discharge shell, a cavity connecting frame is slidably arranged inside the chute frame, the front side of the cavity connecting frame is connected to the rear side of the discharge shell, a lead screw is rotatably arranged inside the chute frame and threadedly connected to the cavity connecting frame, a drive unit is provided at the upper end of the chute frame, the drive unit can drive the lead screw to rotate, the drive unit includes a motor one arranged at the upper end of the chute frame, the output shaft of the motor one is connected to the upper end of the lead screw through a coupling.

[0006] As a further improvement of this utility model, a support mounting plate is provided on the outer side of the storage box, and the storage box and the support mounting plate are fixed together by welding. The support mounting plate has multiple mounting holes inside.

[0007] As a further improvement of this utility model, an observation window is provided in the installation opening on the front side of the storage box.

[0008] As a further improvement of this utility model, an impeller is rotatably arranged inside the discharge shell via a rotating column, and a second motor is arranged on the left side of the discharge shell. The output shaft of the second motor is connected to the left end of the rotating column via a coupling.

[0009] As a further improvement of this utility model, an electric push rod is provided at the upper end of the storage box, and a disintegration frame is provided on the telescopic end of the electric push rod.

[0010] As a further improvement of this utility model, each of the feed inlets at the top of the storage box is provided with a feed shell, and the inside of the feed shell is hinged with a sealing plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] Firstly, by controlling the operation of the second motor, dust continuously falls from the inside of the discharge shell and the sliding shell onto the feeding area of ​​the elevator, thereby realizing the dust feeding operation of the elevator. At the same time, the observation window allows personnel to observe and understand the capacity of lime powder inside the storage bin in real time.

[0013] Secondly, by controlling the start of the motor, the cavity connecting frame, under the constraint of the chute frame, drives the sliding shell to move downward or upward, ensuring that the sliding shell maintains a suitable distance from the feeding area of ​​the elevator, thereby avoiding dust accumulation during lime powder feeding. The size of the discharge shell can be flexibly adjusted according to elevators of different heights to ensure that the discharge shell maintains a close distance from the feeding area of ​​the elevator, avoiding dust accumulation during lime powder feeding, preventing lime powder waste, improving the working environment, and protecting the health of operators.

[0014] Thirdly, by controlling the operation of the electric push rod, the telescopic end drives the dispersing frame to move up and down, which can break up the clumps of lime powder inside, making subsequent feeding smooth and avoiding lime powder blockage. Attached Figure Description

Detailed Implementation

[0021] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0022] like Figure 1 , 2 As shown in Figures 3 and 4, a feeding device for a hoist includes a storage bin 101. A discharge shell 102 is disposed within a discharge port at the lower end of the storage bin 101. A sliding shell 201 is slidably disposed inside the discharge shell 102. A chute frame 203 is disposed on the rear side of the discharge shell 102. The chute frame 203 is slidably disposed inside a cavity connecting frame 204. The front side of the cavity connecting frame 204 is connected to the rear side of the discharge shell 102. A rotatable connection between the chute frame 203 and the cavity connecting frame is rotatably disposed inside the chute frame 203. A lead screw 205 with a 204 threaded connection is provided. A drive unit is provided at the upper end of the slide frame 203. An impeller 106 is provided inside the discharge shell 102 through a rotating column. A second motor 105 is provided on the left side of the discharge shell 102. The output shaft of the second motor 105 is connected to the left end of the rotating column through a coupling. An electric push rod 301 is provided at the upper end of the storage box 101. A disintegrating frame 302 is provided on the telescopic end of the electric push rod 301. The disintegrating frame 302 is located inside the storage box 101.

[0023] like Figure 3 , 4 As shown, the drive unit can drive the lead screw 205 to rotate. The drive unit includes a motor 202 mounted on the upper end of the slide frame 203. The output shaft of the motor 202 is connected to the upper end of the lead screw 205 via a coupling.

[0024] like Figure 1As shown, a support mounting plate 107 is provided on the outer side of the storage box 101. The support mounting plate 107 has multiple mounting holes. The support mounting plate 107 can provide stable support for the feeding device. The mounting holes inside can also be used with mounting bolts to fix it in a suitable position to ensure that the feeding device operates more stably.

[0025] like Figure 1 As shown, each of the feed inlets at the top of the storage bin 101 is equipped with a feed shell 103. The inside of the feed shell 103 is hinged to a sealing plate 104. Operators can open the sealing plate 104 and add lime powder into the storage bin 101 from the inside of the feed shell 103.

[0026] The operator first moves the feeding area of ​​the elevator to the lower end of the sliding shell 201, and then starts the motor 105 by controlling it. The output shaft drives the impeller 106 on the rotating column to rotate, so that the dust falls between the rotating impeller 106 under the action of gravity. This allows the dust to fall continuously from the discharge shell 102 and the inside of the sliding shell 201 onto the feeding area of ​​the elevator, thereby realizing the dust feeding operation of the elevator.

[0027] The motor 202 can be turned on by controlling it to run. The output shaft drives the lead screw 205 to rotate, which in turn causes the cavity connecting frame 204 to move the sliding shell 201 downward or upward under the constraint of the slide frame 203. This ensures that the sliding shell can maintain a close and suitable distance from the feeding area of ​​the elevator, thereby avoiding the occurrence of dust spreading when lime powder is fed.

[0028] Meanwhile, during the feeding process of the elevator, the electric push rod 301 can be opened by controlling it to run. The telescopic end drives the disintegrating frame 302 to move up and down, which can break up the clumps of lime powder inside, making it easier to feed the material smoothly afterwards.

[0029] According to another embodiment of the present invention, such as Figure 1 As shown, an observation window 108 is provided in the installation opening on the front side of the storage box 101. Through the observation window 108, personnel can easily observe and understand the capacity of lime powder inside the storage box 101 in real time.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
