Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Examples

As shown in fig. 1-3, a pellet press comprises a frame 1, a feeding assembly 2, a pellet pressing assembly 3 and a pellet conveying assembly 4; a supporting plate 5 is fixedly arranged right below the ball pressing assembly 3; the upper end surface of the supporting plate 5 is provided with a flexible receiving plate 6; the flexible receiving plate 6 is in an inverted V shape; the pellet transport assembly 4 is located below the pallet 5.

Through setting up the flexible material receiving plate 6 that is the shape of falling "V", on the one hand can effectively reduce the decline height of pellet, on the other hand flexible material can produce slight deformation when receiving the impact material to play the cushioning effect. The flexible material receiving plate 6 can be made of rubber, soft plastic or other materials with certain flexibility.

Specifically, in order to further improve the buffering effect, a plurality of springs 7 are installed between the upper end face of the supporting plate 5 and the lower end face of the flexible receiving plate 6.

Specifically, the flexible material receiving plate 6 is provided with a plurality of holes. During the ball pressing process, part of the crushed aggregates can not be formed into balls, and the crushed aggregates can fall on the supporting plate 5 below through the holes on the flexible receiving plate 6, so that the crushed aggregates and the balls are separated.

Specifically, for facilitating the discharge of the crushed aggregates, the supporting plate 5 is obliquely arranged, and the opposite lower end of the supporting plate penetrates through the avoiding groove 11 in the frame 1.

Specifically, in order to facilitate the collection of the crushed aggregates, the outer part of the frame 1 is provided with a crushed aggregate bin 12; the crushed bin 12 is located below the pallet 5.

Specifically, in order to facilitate the collection of the pellets, the outer wall of the frame 1 is provided with a discharge sloping plate 9 through a bracket 10; the high end of the discharging inclined plate 9 is not higher than the conveying working surface of the pellet conveying assembly 4.

Specifically, the discharge swash plate 9 includes a bottom plate 901; a grid 903 is provided on the base 901. Once the pellets are broken, fragments are produced, which, because of their large size, cannot be entrained in the pellets by the holes in the flexible receiving plate 6. After being conveyed to the discharge inclined plate 9 by the pellet conveying assembly 4, the fragments can fall through the gaps of the grating 903 due to the larger gaps of the grating 903, so that the fragments are separated from the pellets.

Specifically, in order to prevent the pellets from sliding off from both sides of the bottom plate 901, the discharge inclined plate 9 further includes a guard plate 902; the shields 902 are fixedly mounted on both sides of the base 901.

Specifically, in order to improve the installation strength of the discharge inclined plate 9, two groups of brackets 10 are provided, and the two groups of brackets 10 are respectively installed on two sides of the discharge inclined plate 9; each set of brackets 10 comprises two struts forming a triangular structure with the base 901.

Specifically, in order to prevent the pellets from sliding off from both sides of the pellet conveying assembly 4, two baffles 8 are also installed on the frame 1; two baffles 8 are located on either side of the pellet transport assembly 4.

The working principle of the utility model is as follows:

during operation, the mixture falls above the ball pressing assembly 3 through the feeding assembly 2, and the mixture is pressed by the ball pressing assembly 3 to form pellets. The pellet falls on flexible receiving plate 6, because flexible receiving plate 6 is the shape of falling "V", can effectively reduce the decline height of pellet to under the combined cushioning effect of flexible material and spring 7, the impact force of pellet descends by a wide margin, can greatly reduced pellet because of the probability that impact force is great broken. The pellets fall on the flexible receiving plate 6 and slide along the surface thereof, and then fall on the pellet conveying assembly 4 below and are conveyed out. In the process that the pellets slide along the surface of the flexible material receiving plate 6, partial crushed aggregates which cannot be formed into balls in the ball pressing process can fall on the supporting plate 5 below through holes in the flexible material receiving plate 6, so that the crushed aggregates and the pellets are separated. Due to the inclined arrangement of the pallet 5, the particles slide along the pallet 5 and fall into the particle bin 12 for collection. Once the pellets are broken, fragments are produced, which, because of their large size, cannot be entrained in the pellets by the holes in the flexible receiving plate 6. After the pellets are conveyed to the discharge inclined plate 9 by the pellet conveying assembly 4, fragments can fall through the gaps of the grids 903 due to the large gaps of the grids 903, so that the fragments are separated from the pellets.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
