DETAILED DESCRIPTION

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which embodiments of the application belong. The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application.

[0025] Furthermore, directional terms such as "front", "back", "up", "down", "left", "right", "side", "top", "bottom", and the like are used with reference to the orientation of the various example structures and elements shown in the drawings and are merely used for convenience in providing a frame of reference to describe the application. As such, directional terms are used with reference to the orientation shown in the drawings. Therefore, terms such as "up", "down", "front", "back", "side", "top", "bottom" do not inherently describe a spatial orientation with respect to gravity or the earth's gravitational field.

[0026] A casting solid waste transfer device is further described in detail below in combination with the drawings.

[0027] As shown in FIG. Figures 1 to 5 A casting solid waste transfer device includes a screw feeder and a conveyor belt 11. The screw feeder is vertically arranged inside a storage pit 14, and the conveyor belt 11 is arranged outside the storage pit 14. An upper discharge passage 102 of the screw feeder is located directly above the conveyor belt 11.

[0028] In use, the screw feeder and the conveyor belt 11 are started. The screw feeder transfers the sand mold casting waste inside the storage pit 14 onto the conveyor belt 11, and then the waste is conveyed to a designated location by the conveyor belt 11, thereby completing the casting solid waste transfer work.

[0029] Since the storage pit 14 is generally a rectangular pit, if the screw feeder is fixed, the waste on the far side cannot be transferred in the case of a small amount of sand mold casting waste stored inside the storage pit 14.

[0030] Therefore, in the present embodiment, a driving mechanism is arranged outside the storage pit 14. The driving mechanism drives the screw feeder to reciprocate along the arrangement direction of the conveyor belt 11 at the lowest point of the inclined pit bottom 1401 inside the storage pit 14.

[0031] The two sides of the conveyor belt 11 are provided with side baffles 12, and the discharge port of the upper discharge passage 102 is located between the two side baffles 12. At least one side baffle 12 is provided with a dust suction pipe 13 on the inner side, and the dust suction pipe 13 is provided with a through hole. In this way, the waste discharged from the discharge port of the upper discharge passage 102 will not be thrown outside the conveyor belt 11. The dust suction pipe 13 is connected with an induced draft fan and a dust collection bag. The dust generated during the discharging process is sucked into the dust suction pipe 13, and then collected in the dust collection bag, thereby realizing dust-free transfer of the waste.

[0032] The driving mechanism comprises a second motor 7, the output shaft of the second motor 7 is connected with a screw rod 6, the screw rod feeder is fixed with a nut sleeve 5, and the nut sleeve 5 is threadedly connected with the screw rod 6.

[0033] Since the screw rod feeder has a certain weight and has a certain resistance when moving in the waste material, if only the screw rod 6 is used for driving, the nut sleeve 5 bears too large torsional stress and is prone to breakage. Therefore, in the embodiment, the screw rod 6 is arranged with a parallel rod 9 at intervals, the two are arranged in parallel with each other, the screw rod feeder is provided with a connecting block 10, the connecting block 10 is sleeved on the parallel rod 9, and the two ends of the parallel rod 9 and the screw rod 6 are supported by a stand column 8.

[0034] The parallel rod 9 can be a sliding rod or a threaded rod, if the threaded rod is used, the threaded rod is threadedly connected with the connecting block 10. The end of the parallel rod 9 and the end of the screw rod 6 are provided with a belt pulley or a chain wheel, and the two are connected by a synchronous belt or a chain.

[0035] The screw rod feeder comprises a pipe body 1, the pipe body 1 is rotatably connected with a feeding screw rod 2 inside, the feeding screw rod 2 is connected with a first motor 3 at the top end and penetrates to the outside of the pipe body 1, the lower part of the circumferential surface of the pipe body 1 is throughly connected with a lower feeding channel 101, the upper part of the circumferential surface of the pipe body 1 is throughly connected with an upper discharging channel 102, the feeding port of the lower feeding channel 101 is arranged upward, and the discharging port of the upper discharging channel 102 is arranged downward.

[0036] The nut sleeve 6 is fixedly connected with the pipe body 1, and the connecting block 10 is fixedly connected with the base of the first motor 3.

[0037] The pipe body 1 is provided with symmetrically arranged pushers 4 on the circumferential surface, and the pushers 4 are arranged in the direction of the pipe body 1. The horizontal cross-sectional shape of the pusher 4 is an isosceles triangle, which plays a role of distributing material and reducing the moving resistance.

[0038] The embodiments of the application are described in detail above with reference to the drawings, but the application is not limited to the above-described embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the purpose of the application.
