Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, and in particular to a hook-type shot blasting machine shot lifting mechanism. Background Technology

[0002] The shot lifting mechanism of a hook-type shot blasting machine refers to a type of equipment used in hook-type shot blasting machines. It is used to lift the shot used in the shot blasting process to the position of the shot blasting device for cleaning the workpiece. In the process of shot blasting large workpieces, the lifting structure is used to lift the shot to the required position and then cooperates with the shot blasting machine to clean the large workpiece.

[0003] In the prior art, when shot is lifted by a lifting structure, there is a certain gap between the hopper containing the shot and the inner wall of the shot collection cavity during the lifting process. The vibration of the overall structure affects the lifting process, making it easy for the shot to fall through the gap, thereby affecting the efficiency of shot lifting. To address the above problem, the document with application number 202322379788.9 discloses a hook-type shot lifting mechanism for shot blasting machines, which includes an outer shell. A lifting frame is fixedly connected to the top of the outer shell, and a lifting assembly is fixedly connected to the rear end of the outer shell. The lifting assembly includes a discharge hopper fixedly installed at the rear end of the upper part of the outer shell. A protective shell is fixedly connected above the discharge hopper, and two transmission rollers are symmetrically and evenly distributed and movably connected between the inner sidewalls of the protective shell.

[0004] However, a thorough reading of the aforementioned patent documents reveals the following shortcomings: While it can filter impurities in shot blasting, the filter components are located inside the shot blasting machine, making it inconvenient to remove the filtered impurities from the machine. This results in certain inconveniences and poor practicality, which need to be improved.

[0005] Therefore, we propose a hook-type shot blasting machine shot lifting mechanism to solve the problems in the background technology. Utility Model Content

[0006] The purpose of this utility model is to provide a hook-type shot blasting machine shot lifting mechanism, which not only achieves the effect of automatically lifting shot, but also screens and filters impurities in shot during the lifting and conveying process, and facilitates the collection of impurities.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a hook-type shot blasting machine shot lifting mechanism, including a base plate, a shot blasting machine shell and a lifting mechanism;

[0008] The base plate is provided with a shot blasting machine housing, the shot blasting machine housing is provided with a lifting mechanism, and the shot blasting machine housing is provided with a conveying mechanism and connected to the lifting mechanism;

[0009] The lifting mechanism includes a shot lifting pipe, a rotating shaft, a first spiral plate, a second spiral plate, a discharge pipe, a waste discharge pipe, and a motor. The shot lifting pipe is fixedly installed on one side of the shot blasting machine housing. A through hole is opened on one side of the shot blasting machine housing, corresponding to the shot lifting pipe. A rotating shaft is rotatably connected inside the shot lifting pipe. A first spiral plate is fixedly sleeved on the rotating shaft. Through the coordinated design between the shot blasting machine housing, the conveying mechanism, and the lifting mechanism, not only can the shot be automatically lifted, but also the impurities in the shot can be screened and filtered during the lifting and conveying process. It also facilitates the collection of impurities, greatly improving convenience and practicality.

[0010] A further feature of this invention is that a spiral plate II is fixedly fitted onto one end of the rotating shaft. The spiral plate II has multiple shot sieve holes. These holes allow shot to pass through, thus achieving the effect of screening larger impurities and preventing the shot from being transported into the discharge pipe. A discharge pipe is sealed to one side of the shot lifting pipe. One end of the discharge pipe is sealed to the outer casing of the shot blasting machine. A shot sieve II is fixedly installed at one end of the discharge pipe. When the shot moves to the position of the discharge pipe, the shot sieve II passes through it and is discharged through the discharge pipe, thereby achieving the effect of screening larger impurities in the shot.

[0011] A further feature of this invention is that both the second spiral plate and the first spiral plate rotate within the shot and sand lifting pipe and are adapted to the shot and sand lifting pipe. One end of the shot and sand lifting pipe is fixedly installed with a first motor, and the output end of the first motor is fixedly connected to the rotating shaft. Driven by the first motor, the rotating shaft rotates within the shot and sand lifting pipe. At the same time, the rotating shaft drives the first spiral plate and the second spiral plate to rotate synchronously within the shot and sand lifting pipe, thereby achieving the effect of lifting and conveying the shot and sand.

[0012] A further feature of this invention is that a discharge pipe is sealed to one side of the shot lifting pipe, the discharge pipe corresponds to the second spiral plate, and the discharge pipe corresponds to the first spiral plate, which facilitates the discharge of larger impurities screened out.

[0013] A further feature of this invention is that the conveying mechanism includes a screw rod, a second electric motor, and a shot sieve plate. The screw rod is rotatably connected inside the shot blasting machine housing, corresponding to the through hole. One end of the screw rod penetrates the shot blasting machine housing.

A sprocket is fixedly connected to the output end of the second electric motor, and a chain is connected to the first sprocket. One end of the chain is connected to a second sprocket, which is fixedly sleeved on the screw rod. Driven by the second electric motor, the first sprocket rotates and, through the chain, drives the second sprocket to rotate synchronously. Simultaneously, the second sprocket drives the screw rod to rotate inside the shot blasting machine housing. Thus, the screw rod effectively conveys the shot to the shot lifting pipe.

[0014] A further feature of this invention is that a guide plate is fixedly installed inside the casing of the shot blasting machine, and a discharge port is provided at one end of the guide plate. The discharge port corresponds to the screw rod. Through the action of the guide plate, the shot and sand inside the casing of the shot blasting machine can be guided to one end of the screw rod.

[0015] A further feature of this invention is that the outer casing of the shot blasting machine is provided with an installation groove, and a shot sieve plate is fixedly installed in the installation groove. The shot sieve plate corresponds to the spiral rod. Through the action of the shot sieve plate, smaller impurities in the shot can be screened and fall into the collection box below the shot sieve plate, thereby achieving the effect of filtering the shot.

[0016] A further feature of this invention is that a bearing is fixedly sleeved at one end of the spiral rod, and the outer wall of the bearing is fixedly connected to the housing of the shot blasting machine to facilitate the rotation of the spiral rod.

[0017] A further feature of this invention is that a hoisting slot is provided on the top of the shot blasting machine housing, and a door is provided on the shot blasting machine housing.

[0038] Working principle: During use, the guide plate 16 can guide the shot and sand inside the shot blasting machine housing to one end of the spiral rod 3;

[0039] Then, the motor 12 drives the sprocket 13 to rotate and the chain 14 drives the sprocket 15 to rotate synchronously.

[0041] During this process, when the shot moves to the position of the discharge pipe 9, the shot passes through the shot screen plate 2 17 and is discharged through the discharge pipe 9, thereby achieving the effect of screening larger impurities in the shot.

[0042] Meanwhile, through the combined action of spiral plate 7 and spiral plate 8 with shot and sand lifting pipe 5, larger impurities after screening can be conveyed to the collection box, and then placed into the collection box through discharge pipe 10, thereby achieving further filtration of impurities.

[0043] The technological advancements of this invention compared to existing technologies are as follows: through the cooperation of various components, not only can the automatic lifting of shot be achieved, but also the screening and filtering of impurities in the shot can be carried out during the lifting and conveying process, and the collection of impurities is also convenient, greatly improving convenience and practicality.
