DETAILED DESCRIPTION

[0019] by Figure 1 The up, down, left, right, front and back directions of the illustrated embodiment are defined.

[0020] As shown in the figure, this embodiment includes a shell 1, and a feed port 2 is arranged at the upper end of the shell 1, and the feed port 2 is communicated with the inner cavity of the shell 1; a guide plate 3 is arranged below the feed port 2, and the left side of the guide plate 3 is arranged downwardly inclined, and is fixedly connected to the upper inner wall of the shell 1, and a feed port is formed between the lower end of the left side of the guide plate 3 and the shell 1, which guides the raw materials fed into the feed port 2. A screening plate 4 is arranged below the feed port, and the right end of the screening plate 4 is arranged downwardly inclined from the feed port; the upward part of the screening plate 4 is a flat plate structure, which can receive the raw materials and convey them downward; the downward part of the screening plate 4 is provided with a screen 5, which can screen the raw materials. A vibrator 8 is arranged at the lower end of the flat part of the screening plate 4, which can vibrate the raw materials during the conveying process. A base 6 is arranged at the lower end of the screening plate 4, and the screening plate 4 is fixed by a pin connected to the shell 1 through a sleeve in the base 6; a rubber pad 7 is arranged at the contact position between the pin and the base 6, which can buffer and protect the contact surface between the base 6 and the pin during the vibration process. A first discharge port 16 is provided on the housing 1 near the screen 5 , through which the raw materials screened by the screen 5 can be discharged.

[0021] A first combing tooth plate 9 is arranged above the screening plate 4. The first combing tooth plate 9 is composed of a group of combing plates 11 and a base plate 10 connected to each combing plate at the upper end, and is located at the lower part of the flat plate part of the screening plate 4. In this embodiment, 14 combing plates 11 are arranged. The combing plates 11 are in the same inclination direction as the screening plate 4, and the lower end surface is adapted to the upper surface of the flat plate part of the screening plate 4, which can ensure that the raw materials pass through the gaps between the combing plates 11. During use, in cooperation with the vibrator 8, the raw materials can collide with the combing plates 11 when passing through the gaps between the combing plates 11, thereby breaking up the raw materials. In this embodiment, a tooth plate shaft 12 is arranged at one end of the base plate 10 close to the discharge port, and protrusions are arranged on the left and right sides of the tooth plate shaft 12, which are slidably connected to the base plate 10. The front end of the tooth plate shaft 12 is rotatably connected to the outer shell 1, and the rear end passes through the outer shell 1 and is connected to a stepping motor 13. When in use, the first combing tooth plate 9 can be controlled to swing up and down by driving the stepping motor 13. When the raw material is too large to pass through the gap between the combing plates 11, the stepper motor 13 can be controlled to lift the first combing tooth plate 9 to prevent the raw material from accumulating on the side of the first combing tooth plate 9 close to the discharge port. A screw hole 14 is provided at the front end of the base plate 10, and a bolt 15 passing through the housing 1 is provided in front of the screw hole 14; during use, the bolt 15 can be screwed into the screw hole 14, and the first combing tooth plate 9 can be pushed and pulled back and forth to clean the raw material attached to the upper surface of the screen plate, and avoid the accumulation and blockage of the raw material in the first combing tooth plate 9. After cleaning, the bolt 15 needs to be unscrewed to avoid affecting the up and down swing of the first combing tooth plate 9.

[0022] A receiving plate 17 is provided below the screening plate 4, and one end of the receiving plate 17 close to the screen 5 is a receiving hopper 18, and a second discharge port 19 is provided at the lower end of the receiving hopper 18 for conveying the screened raw materials; the other end of the receiving plate 17 is a straight horizontal plate structure, which provides an installation space for the vibrator 8, and a vertical partition is provided between the receiving plate 17 and the receiving hopper 18, which can prevent the raw materials and dust from entering the vibrator 8 during the falling process of the screen 5, thereby playing a dust-proof protection role.

[0023] In this embodiment, two-stage screening plates are provided. The second-stage screening plate 23 has a structure and an inclination direction opposite to the screening plate 4. A second combing tooth plate 20 is provided above, and a vibrating machine and a receiving plate corresponding to the structure are provided below, so as to realize multi-stage screening of raw materials.

[0024] A second-stage screening plate 23 is provided below the receiving plate 17. The left end of the second-stage screening plate 23 is tilted downward from the second unloading port 19. A second discharge port 21 is provided on the housing 1 near the screen portion of the second-stage screening plate 23, which can discharge the raw materials screened by the second-stage screening plate 23. A third discharge port is provided below the screen portion of the second-stage screening plate 23 for collecting the final screened raw materials.

[0025] When the utility model is in use, each vibrator is started, and the raw material is poured from the feed port 2. The raw material falls on the upper end of the screen plate 4 through the guide plate 3, starts to vibrate through the vibrator 8 and enters the gap of the first combing tooth plate 9. The raw material collides with the combing plate 11 as the vibrator 8 vibrates, so that the raw material is broken up. The broken raw material is screened through the screen 5, and the raw material with larger particles is discharged through the first discharge port 16, and the raw material with smaller particles falls on the second-stage screen plate 23 through the second discharge port 19. The raw material passes through the second combing tooth plate 20 and is subjected to secondary screening. The raw material with larger particles screened out is discharged through the second discharge port 21, and the raw material with smaller particles is discharged through the third discharge port 22, so that the screening of the bacterial fertilizer raw material is completed.
