DETAILED DESCRIPTION

[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0023] Reference Figures 1 to 3 The utility model discloses a machine-made sand conveying device, which includes a frame 10, a hopper 20 and a conveyor belt 30.

[0024] The conveyor belt 30 is installed on the frame 10, and a motor 50 is arranged beside the frame 10. The motor 50 is connected to an active roller 300 arranged on one side of the output end of the conveyor belt 30 through a pulley mechanism. The conveyor belt 30 is kept in operation under the drive of the motor 50.

[0025] Reference Figure 1 and Figure 2 The hopper 20 is arranged in an inclined shape, and has a group of horizontal extensions 21 at its upper end. The side walls on both sides of the extensions 21 are provided with a plurality of mounting holes 210. The extensions 21 can be detachably fixed to the frame 10 by passing bolts through the mounting holes 210, so that the hopper 20 is fixed to the output end of the conveyor belt 30, and the hopper 20 is located below the conveyor belt 30. After the machine-made sand output by the conveyor belt 30 falls into the hopper 20, it is exported to the subsequent storage site through the hopper 20.

[0026] Among them, the hopper 20 is also provided with a brush roller assembly 40 for brushing the surface of the conveyor belt 30, and the brush roller assembly 40 includes a horizontal axis 402, a brush cylinder 400 rotatably mounted on the horizontal axis 402, and bristles 401 installed on the outer wall of the brush cylinder 400, wherein the horizontal axis 402 is parallel to the active roller 300, and the two ends of the horizontal axis 402 are installed on the side walls on both sides of the hopper 20.

[0027] Among them, refer to Figure 2The brush cylinder 400 is driven and connected to the active roller 300 through a sprocket mechanism 70, that is, a first sprocket 700 is installed at the end of the brush cylinder 400, and a second sprocket 701 is installed at the end of the active roller 300. The first sprocket 700 and the second sprocket 701 are connected by a chain 702. In addition, a sprocket cover 703 for dust prevention is also installed on the sprocket mechanism 70. During the operation of the conveyor belt 30 driven by the motor 50, the active roller 300 drives the brush cylinder 400 to rotate through the sprocket mechanism 70. At this time, the bristles 401 on the brush cylinder 400 can brush off the powder sand agglomerates on the surface of the conveyor belt 30 and drop them into the hopper 20 below.

[0028] Taking into account that different water contents in machine-made sand will result in different sizes of powdered sand agglomerates, the distance between the brush roller assembly 40 and the surface of the conveyor belt 30 will affect the cleaning effect of the bristles 401. Therefore, both ends of the horizontal axis 402 are installed on the hopper 20 in a liftable and adjustable manner, and the distance between the brush roller assembly 40 and the conveyor belt 30 can be adjusted.

[0029] The tightness of the chain 702 within a certain range does not affect the operation of the sprocket mechanism 70, that is, the vertical lifting of the horizontal axis 402 does not affect the sprocket mechanism 70 transmitting power to the brush roller assembly 40. Therefore, in some embodiments, the two ends of the horizontal axis 402 can be lifted and lowered by threaded push rods.

[0030] In a more preferred embodiment, in order to ensure that the tightness of the chain 702 remains consistent during the lifting and lowering of the horizontal axis 402, refer to Figure 3 A group of arc holes 200 are respectively opened on the side walls on both sides of the hopper 20, and the center of the arc side of each group of arc holes 200 is located on the axis of the active roller 300. The two ends of the horizontal axis 402 are respectively penetrated in a group of arc holes 200. During the up and down movement of the horizontal axis 402 in the arc hole 200, the distance between the horizontal axis 402 and the active roller 300 remains unchanged. Therefore, the lifting and lowering of the horizontal axis 402 does not affect the tightness of the chain 702.

[0031] Accordingly, in order to facilitate the lifting and lowering adjustment of the horizontal axis 402, refer to Figure 3A group of ball joints 60 located below the arc hole 200 are also installed on both side walls of the hopper 20, that is, a group of support platforms 201 are welded on the outer walls on both sides of the hopper 20, and the ball pin seat 600 in the ball joint 60 is installed on the support platform 201, wherein the ball pin rod 602 in the ball joint 60 includes a smooth rod section 6020 and a threaded section 6021, wherein the lower end of the smooth rod section 6020 of the ball pin rod 602 is installed on the ball pin body 601 in the ball joint 60, and the threaded section 6021 at the upper end of the ball pin rod 602 passes through the horizontal axis 402 on the same side, and a spring for supporting the horizontal axis 402 is sleeved on the smooth rod section 6020, and a nut 603 pressed against the horizontal axis 402 is connected to the threaded section 6021, wherein the threaded mesh 603 adopts a butterfly nut, and the spring can be extended / compressed by tightening / loosening the threaded mesh 603, thereby adjusting the height of the entire brush roller assembly 40.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
