Abstract
Description
Technical Field
[0001] This utility model relates to the field of coal conveying equipment, specifically to a coal drop point adjustment device for a feed chute. Background Technology
[0002] As shown in the Chinese patent with authorization announcement number CN 208716255 U, there is currently a type of belt conveyor coal flow regulating guide trough structure on the market for guiding coal conveying. It uses screws directly installed on the shell to push the guide plate to change the guide angle. Since the screws and screw holes are directly exposed in the coal conveying pipeline, after a period of use, sticking and difficulty in rotation will occur. Utility Model Content
[0003] In order to overcome the shortcomings of the prior art, this utility model provides a coal drop point adjustment device for the guide chute, which mainly solves the problem that the adjustment parts of the current guide chute are easy to be difficult to rotate.
[0004] The technical solution of this utility model is as follows:
[0005] The coal drop point adjustment device for the feed chute includes a housing and a rotatable adjustment plate connected to the housing, and also includes...
[0006] A cylindrical body, at least partially disposed within the housing, has an axially provided through groove, the through groove including a first smooth portion and a first threaded portion;
[0007] An adjusting member includes a second smooth portion and a second threaded portion, the second threaded portion engaging with the first thread, the top end of the adjusting member extending into the housing and positioned opposite the adjusting plate, and the other end extending out of the housing;
[0008] A sealing element is disposed on the inner wall of the first smooth part and is in sealing fit with the outer wall of the second smooth part.
[0009] The sealing element is a sealing ring.
[0010] The sealing element is provided in multiple parts along the axial direction of the through groove.
[0011] The adjusting member extending out of the housing is equipped with a handwheel.
[0012] The cylindrical body is installed on the shell by welding.
[0013] The back of the adjustment plate is provided with a guide groove, and part of the adjustment element extends into the guide groove.
[0014] The outer wall of the adjusting member that extends into the guide groove is a smooth spherical surface.
[0015] The beneficial effects of this utility model are: This utility model provides a coal drop point adjustment device for the feed chute, the adjustment component is sealed as a whole to prevent dust from entering, facilitates rotation, and increases service life. Attached Figure Description
[0016] Figure 1 This is a structural schematic diagram of one embodiment of the present invention.
[0017] Figure 2 This is a partial structural diagram of one embodiment of the present invention.
[0018] Figure 3 This is a partial cross-sectional view of one embodiment of the present invention. Detailed Implementation
[0019] The present invention will be further described below with reference to the accompanying drawings. The coal drop point adjustment device for the feed chute includes a housing 1 and a rotatable adjustment plate 2 connected to the housing. It also includes a cylinder 3, at least partially disposed within the housing, with an axially arranged through groove 31. The through groove includes a first smooth portion 311 and a first threaded portion 312. An adjustment member 4 includes a second smooth portion 41 and a second threaded portion 42, the second threaded portion engaging with the first threaded portion. The top end of the adjustment member extends into the housing and is positioned opposite to the adjustment plate, while the other end extends out of the housing. A sealing member 5 is disposed on the inner wall of the first smooth portion and seals against the outer wall of the second smooth portion. Material enters from the drop port 10 and is guided by adjusting the angle via the adjustment plate. This is prior art; reference can be made to Chinese Patent CN 208716255 U. The feature of this application is that the adjustment member is installed within the cylinder, providing a sealing effect and preventing dust from entering the threaded portion and causing blockage. Preferably, the first smooth portion is at least partially disposed within the housing, while the first threaded portion is disposed outside the housing.
[0020] In this embodiment, as shown in the figure, the sealing element is a sealing ring. It is low in cost, and multiple rings can be used to achieve a better sealing effect.
[0021] In this embodiment, as shown in the figure, multiple seals are provided along the axial direction of the through groove.
[0022] In this embodiment, as shown in the figure, the adjusting member extending out of the housing is equipped with a handwheel 43 for easy manual operation.
[0023] In this embodiment, as shown in the figure, the cylinder is welded onto the shell. Installation is relatively convenient, as a through hole is made in the shell for cylinder mounting.
[0024] In this embodiment, as shown in the figure, a guide groove 22 is provided on the back of the adjusting plate, and part of the adjusting member extends into the guide groove. The guide groove is a vertical groove used to guide the range of motion of the adjusting member.
[0025] In this embodiment, as shown in the figure, the outer wall of the adjusting member extending into the guide groove is a smooth spherical surface. This reduces friction.
[0026] In the description of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.
