Description

Technical Field

[0001] The utility model relates to the field of crusher equipment, and particularly relates to a splash-proof feeding device for a crusher. Background Art

[0002] At present, the application of existing machine equipment such as feed and forage crushers and straw chopping and silk rubbing crushers has been very common. However, the problem of material splashing at the feeding place has never been effectively solved. Generally, at the feeding port, there is only a plug board that can be inserted and withdrawn up and down or left and right in parallel to control the amount of feeding. When crushing small granular materials such as corn kernels and grains, when the plug board is used, the opening amplitude of the plug board is smaller, and the situation is much better. When there is a lot of material, since the material blocks the opening, the feeding will not splash out. However, when the material is finished, the material entering the machine will inevitably splash out from the feeding port, causing waste or injury. If the material has a relatively large volume, such as corn cobs and dried potato chips, when the opening of the plug board needs to be large, the situation is different. If it is small, the material cannot enter. If the opening is large, more materials will fly out and fly farther. More waste will be caused, and the degree and probability of personal injury will be greater. Content of the Utility Model

[0003] In view of the above deficiencies in the prior art, the utility model provides a splash-proof feeding device for a crusher. Due to the mutual occlusion of the two plug boards and the change of the path of the splashed materials, the splashed materials will re-enter the machine by themselves after multiple discharges and will not fly out of the feeding hopper. In this way, the personal injury and material loss are reduced.

[0004] In order to achieve the above-mentioned utility model purpose, the technical solution adopted by the utility model is as follows:

[0005] A splash-proof feeding device for a crusher, comprising: a feeding hopper and a feeding straight pipe. The feeding hopper is located above the feeding straight pipe, and the feeding hopper is communicated with the feeding straight pipe. An upper plug board guide rail group and a lower plug board guide rail group are respectively installed on the upper and lower parts inside the feeding straight pipe. An upper plug board and a lower plug board are respectively slidably connected inside the upper plug board guide rail group and the lower plug board guide rail group. An upper plug board backing plate and a lower plug board backing plate are respectively fixedly connected to the upper and lower parts outside the feeding straight pipe. The upper plug board backing plate and the lower plug board backing plate respectively fix the positions of the upper plug board and the lower plug board by inserting upper bolts and lower bolts respectively.

[0006] Preferably, both the upper plug board guide rail group and the lower plug board guide rail group have 4 plug board guide rails. Both the upper plug board guide rail group and the lower plug board guide rail group are in an inclined structure, and the inclined directions are opposite.

[0007] The beneficial effects of the utility model are as follows:

[0008] Two lower and upper insertion plates that are arranged vertically and insert and extract in opposite directions. The two plates have a certain inclination angle, which changes the trajectory of the material splashing out inside the machine. Since the opening directions of the two plates are opposite, the feeding ports are not on the same line. They form a structure that can block each other while not affecting feeding. This forces the path of the splashing material to change from the original direct flight to an oblique N shape. Due to the mutual blocking of the two plates and the change in the path of the splashing material, the splashing material will re-enter the machine by itself after multiple rebounds and will not fly out of the feeding hopper. This reduces the harm to the human body and the loss of materials. Description of the Drawings

Detailed Description of the Preferred Embodiment

[0013] The following will further illustrate the specific embodiments of the present utility model with reference to the accompanying drawings. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0014] In order to make the content of the present utility model easier to be clearly understood, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0015] As Figure 1 shown, a feeding anti-splash device for a crusher includes: a feeding hopper 2 and a feeding straight pipe 1. The feeding hopper 2 is located above the feeding straight pipe 1, and the feeding hopper 2 is communicated with the feeding straight pipe 1. The upper and lower parts of the inner side of the feeding straight pipe 1 are respectively provided with an upper insertion plate guide rail group 6 and a lower insertion plate guide rail group 10. The upper insertion plate 7 and the lower insertion plate 4 are respectively slidably connected to the inner sides of the upper insertion plate guide rail group 6 and the lower insertion plate guide rail group 10. The upper and lower parts of the outer side of the feeding straight pipe 1 are respectively fixedly connected with an upper insertion plate backing plate 11 and a lower insertion plate backing plate 5. The upper insertion plate backing plate 11 and the lower insertion plate backing plate 5 respectively fix the positions of the upper insertion plate 7 and the lower insertion plate 4 by inserting the upper bolt 3 and the lower bolt 8.

[0016] Both the upper plug guide rail group 6 and the lower plug guide rail group 10 have 4 plug guide rails. Both the upper plug guide rail group 6 and the lower plug guide rail group 10 are in an inclined structure, and the inclined directions are opposite.

[0017] Embodiment: As Figure 2 , 3 shown in the figure: The upper plug 7 and the lower plug 4 are respectively slidably connected to the inner sides of the upper plug guide rail group 6 and the lower plug guide rail group 10. The positions of the upper plug 7 and the lower plug 4 are changed or the quantity is reduced, but both the upper plug 7 and the lower plug 4 are in an inclined structure, and the inclined directions are opposite. The two plugs have a certain inclination angle, which changes the route trajectory of the materials splashed out inside the machine. Because the opening directions of the two plugs are opposite, the opened feeding ports are not on the same line. They form a situation where they can block each other while not affecting the feeding. In this way, the path of the splashed objects is forced to change from the original direct flying out to an inclined N shape. Due to the mutual blocking of the two plugs and the change in the path of the splashed objects, the splashed objects will re-enter the machine by themselves after multiple splashes and will not fly out of the feeding hopper.

[0018] The above is only a preferred embodiment of the utility model patent, and it is not intended to limit the utility model patent. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model patent shall be included in the protection scope of the utility model patent.
