AI Technical Summary
The existing dust collection hopper has a center of gravity shift due to cylinder counterweight issues, resulting in poor stability and even shaking.
The system employs a switch valve structure consisting of two cylinders and a baffle. The cylinder movement is controlled by a synchronously activated solenoid valve, which balances the overall weight of the dust collection hopper and ensures stability.
The overall weight balance of the dust collection hopper is achieved, which improves the stability during operation and avoids shaking.

Abstract
Description
Technical Field
[0001] This utility model relates to a dust collection hopper. Background Technology
[0002] The lower outlet of the dust collection hopper is usually equipped with a switch valve. The existing switch valve is usually set on a cylinder on one side and a baffle connected to the cylinder. The cylinder drives the baffle to move horizontally to open and close the outlet. Due to the counterweight problem of the cylinder, the center of gravity of the dust collection hopper shifts, resulting in poor stability of the dust collection hopper and even shaking during operation. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide a dust collection hopper, thereby solving the technical problems existing in the prior art.
[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a dust collection hopper, including a body and a switching valve disposed at the outlet end of the body. The switching valve includes a first cover plate connected to the outlet end of the body, a second cover plate disposed below the first cover plate, and a valve assembly. The first cover plate has a first through hole, and the second cover plate has a second through hole. The outlet end of the body, the first through hole, and the second through hole form a discharge channel. A guide groove is provided between the first cover plate and the second cover plate. The valve assembly includes two baffles disposed in the guide groove and arranged opposite to each other, and a cylinder for driving the baffles to move horizontally. The principle of this utility model: the switching valve, composed of two cylinders and baffles, balances the overall weight of the dust collection hopper. Combined with a synchronously activated solenoid valve, the two cylinders move in unison, resulting in good stability of the dust collection hopper during operation.
[0005] As an improvement, the first cover plate includes a first annular body, a first annular plate disposed at the upper end of the first annular body, and a first connecting plate disposed at the lower end of the first annular plate. The first annular plate and the first connecting plate are horizontally arranged, and the first annular body is perpendicular to the first annular plate and the first connecting plate, respectively. The second cover plate includes a second annular body and a second connecting plate disposed at the upper end of the second annular body. The second connecting plate is horizontally arranged and perpendicular to the second annular body. The first connecting plate and the second connecting plate are parallel to each other, and the gap between the first connecting plate and the second connecting plate forms the guide groove.
[0006] As an improvement, baffles are provided on both sides between the first connecting plate and the second connecting plate.
[0007] As an improvement, the two sides of the first connecting plate are bent upwards, and the two sides of the second connecting plate are bent downwards.
[0008] As an improvement, the second connecting plate is provided with support plates at both ends, and the cylinder is fixed on the support plates. The second connecting plate and the support plates are integrally formed.
[0009] The beneficial effects of this utility model compared with the prior art are:
[0010] The switching valve consists of two cylinders and a baffle, which balances the overall weight of the dust collection hopper. Combined with the synchronously activated solenoid valve, the two cylinders move in unison, resulting in good stability of the dust collection hopper during operation. Attached Figure Description
[0011] Figure 1 This is a 3D diagram of a dust collection hopper.
[0012] Figure 2 This is a left-side view of the dust collection hopper.
[0013] Figure 3 This is a front view of the dust collection hopper. Detailed Implementation
[0014] The present invention will be further described below with reference to the accompanying drawings.
[0015] like Figures 1 to 3As shown, a dust collection hopper includes a body 1 and a switching valve located at the outlet end of the body 1. The switching valve includes a first cover plate 2 connected to the outlet end of the body 1, a second cover plate 3 located below the first cover plate 2, and a valve assembly. The first cover plate 2 has a first through hole, and the second cover plate 3 has a second through hole. The outlet end of the body 1, the first through hole, and the second through hole form a discharge channel. The material is stored in the body 1 and is discharged sequentially through the outlet end, the first through hole, and the second through hole. A guide groove is provided between the first cover plate 2 and the second cover plate 3. The guide groove is a variable frequency transverse guide groove that cuts across the discharge channel. The valve assembly includes two baffles 4 disposed in the guide groove and arranged opposite to each other, and a cylinder 5 that drives the baffles 4 to move horizontally. The two cylinders 5 are controlled by the same solenoid valve, which can simultaneously drive the two cylinders 5 to open and close synchronously, that is, the two baffles 4 move synchronously in opposite directions. When the two baffles 4 approach each other, the dust collection hopper closes; when the two baffles 4 move away from each other, the dust collection hopper opens. The first cover plate 2 includes a first annular body, a first annular plate at the upper end of the first annular body, and a first connecting plate at the lower end of the first annular plate. The first annular plate and the first connecting plate are horizontally arranged, and the first annular body is perpendicular to the first annular plate and the first connecting plate, respectively. The second cover plate 3 includes a second annular body and a second connecting plate at the upper end of the second annular body. The second connecting plate is horizontally arranged and perpendicular to the second annular body. The first connecting plate and the second connecting plate are parallel to each other, and the gap between the first connecting plate and the second connecting plate forms the guide groove. There are baffles on both sides between the first connecting plate and the second connecting plate, which are used to separate the first connecting plate and the second connecting plate to form a gap. The two sides of the first connecting plate are bent upwards, and the two sides of the second connecting plate are bent downwards. The bending can strengthen the connecting plate. There are support plates at both ends of the second connecting plate, and the cylinder 5 is fixed on the support plate. The second connecting plate and the support plate are integrally formed. The principle of this utility model is as follows: the switch valve consists of two cylinders 5 and a baffle 4, which makes the overall weight of the dust collection hopper balanced. Combined with the synchronously started solenoid valve, the two cylinders 5 move in unison, and the dust collection hopper has good stability when working.
