DETAILED DESCRIPTION

[0024] The embodiment of the utility model will be described in detail below in combination with the drawings.

[0025] As Figures 1-4 , in the embodiment one, a spraying machine feeding device, comprising

[0026] The vibrating hopper 40 is arranged on the feeding hopper 30, and the lower end of the vibrating hopper 40 is opposite to the feeding hopper 30.

[0027] The sleeve body 50 is fixedly connected to the vibrating hopper 40, and the lower end opening of the sleeve body 50 is partially opposite to the vibrating hopper 40 and partially staggered with the vibrating hopper 40.

[0028] The filter screen 51 is arranged in the sleeve body 50 in an inclined manner.​

[0029] The connecting plate 63 is movably arranged in the sleeve body 50.

[0030] The plurality of positioning pipes 62 are longitudinally arranged and fixedly connected with the connecting plate 63.

[0031] The plurality of push rods 61 are vertically slidably arranged through the positioning pipes 62, and the push rods 61 are arranged on the connecting plate 63 in a liftable manner.

[0032] The limiting plate 70 is fixedly arranged at the lower horizontal end of the filter screen 63 and forms a V shape with the filter screen 63.

[0033] The embodiment is implemented as follows:

[0034] In use, the worker pours the slurry on the filter screen 51 in the sleeve body 50, at this time, the slurry will pass through the filter screen 51, and the large particle stones are blocked on the filter screen 51. When the stones need to be cleaned, the feeding is stopped, at this time, the connecting plate 63 drives the positioning pipes 62 and the push rods 61 to move, so that the push rods 61 move to one side of the limiting plate 70, and the push rods 61 gradually move downward in the moving process, so that the push rods 61 can always contact the filter screen 51. The push rods 61 will push the stones down from the limiting plate 70 and fall from the other part of the lower end of the sleeve body 50, and finally the connecting plate 63 returns to the original position.
