Description

Technical Field

[0001] This utility model relates to the field of pelleting equipment technology, specifically an automatic pelleting machine for poultry feed. Background Technology

[0002] If the gap between the pressure roller and the screen plate in a pellet mill is too large, the raw material will experience uneven force as it passes through the roller, failing to form well-formed granules. Conversely, if the gap is too small, the raw material cannot be fully compressed and degassed, also resulting in unsatisfactory pellet formation. Adjustments to the pressure roller are necessary by observing the material's shape, hardness, and strength. Currently, the gap between the pressure roller and screen plate in existing poultry feed pellet mills is generally not adjustable. Therefore, when dealing with different types of materials, or materials with varying moisture content and particle size, the pellet mill struggles to guarantee effective pelleting. Utility Model Content

[0003] The technical problem solved by this utility model is to provide an automatic granulator that can adjust the gap between the pressure roller and the sieve plate to adjust according to different materials, thereby improving the granulation effect and solving the problems mentioned in the background art.

[0004] The technical problem solved by this utility model is achieved by the following technical solution: an automatic poultry feed pellet mill, comprising a cylinder, a sieve plate rotatably installed inside the cylinder, and an adjustable roller assembly installed on the upper end of the sieve plate. The sieve plate is fixedly installed on a rotating shaft and rotated by the rotating shaft. A transmission box is provided at the lower end of the cylinder to control the rotation of the rotating shaft. The roller assembly includes a pressure shaft and pressure rollers rotatably installed at both ends of the pressure shaft. The two sides of the pressure shaft are respectively inserted into corresponding adjustment holes in the cylinder. A pressure plate is integrally provided at the outer end of the pressure shaft located in the adjustment hole. An adjustment component for synchronously adjusting the height of the two pressure plates is provided at the outer end of the cylinder. A plate is also provided on the inner side of the pressure shaft located inside the cylinder to abut against the inner side of the cylinder and to cover the adjustment hole.

[0005] As a further embodiment of this utility model:

[0006] The adjustment assembly includes an adjustment seat, insert pieces that cooperate with the adjustment seat, and a pusher for controlling the movement of the insert pieces. The adjustment seat includes a vertically arranged adjustment shaft and seat plates on both sides of the adjustment shaft. The seat plates are fixedly installed on the outer end of the cylinder. The pressure plate has a shaft hole in the middle and is slidably installed on the adjustment shaft. A spring sleeved on the adjustment shaft is provided between the lower end of the pressure plate and the seat plate to elastically lift the pressure plate. The insert pieces include insert plates and frame plates that control the movement of the insert plates on both sides of the cylinder. The lower end of the insert plate has an inclined surface structure, and the middle of the insert plate has a shaft groove corresponding to the adjustment shaft. The upper end of the pressure plate has a ramp block that fits against the insert plate. The cylinder has a guide sleeve that slides with the insert plate to keep the insert plate moving horizontally. Specifically, when the insert plate moves forward, the ramp surface squeezes the pressure plate down to reduce the gap between the pressure roller and the screen plate. Conversely, when the insert plate moves backward, the ramp surface gradually rises, and the pressure plate rises under the action of the spring to adjust the height of the pressure roller.

[0007] As a further embodiment of this utility model:

[0008] The pusher includes a screw sleeve disposed in the middle of the frame plate and a screw rod threadedly connected to the screw sleeve. The screw rod is rotatably mounted on the pusher seat, and a handle for controlling the rotation of the screw rod is provided on the outside of the pusher seat, so as to control the forward and backward movement adjustment of the frame plate by rotating the screw rod through the handle.

[0009] As a further embodiment of this utility model:

[0010] A positioning gear is fixedly mounted on the screw between the push seat and the handle. A pin is slidably installed on the upper end of the push seat, and the lower end of the pin is inserted into the tooth groove of the positioning gear to fix the positioning gear and prevent the screw from rotating arbitrarily. When the operator rotates the handle, the pin can be pulled out, and after rotating to the designated position, the pin can be inserted to lock the positioning gear.

[0011] As a further embodiment of this utility model:

[0012] The lower end of the cylinder is provided with a bottom plate, and a feed chamber for receiving particles is formed between the bottom plate and the screen plate. A cutter is installed on the inner wall of the cylinder at the upper end of the feed chamber to cut the particle column extruded from the lower end of the screen plate. An opening is provided on one side of the feed chamber, and a feed hopper is installed at the outer end of the opening. A discharge component for discharging granular material is provided in the feed chamber. The discharge component includes a conical disk fixedly installed at the outer end of the rotating shaft and a discharge plate annularly distributed at the outer end of the conical disk, so that the rotating shaft drives the conical disk and the discharge plate to rotate, and the granular material is thrown into the feed hopper for discharge.

[0013] As a further embodiment of this utility model:

[0014] The lower end of the rotating shaft is mounted on the bearing seat corresponding to the base plate. A first pulley is mounted on the lower end of the rotating shaft on the base plate. A drive motor is mounted on one side of the transmission box. A second pulley is mounted on the lower end of the drive motor on the transmission box. The first pulley and the second pulley are connected by belt drive.

[0015] Compared with existing technologies, the advantages of this invention are as follows: The height of the pressure roller can be adjusted via an adjustable component, allowing for selection and adjustment of the gap between the pressure roller and the screen plate based on different materials, their moisture content, and hardness, thereby improving the granulation effect. Operators control the screw rotation via a handle to move the frame plate back and forth, which in turn moves the insert plate. The height of the pressure plate is adjusted using the slope at the lower end of the insert plate, achieving precise adjustment of the gap between the pressure roller and the screen plate. The device is simple to operate and convenient to use; the adjustment hole can limit the pressure shaft to ensure the minimum gap distance between the pressure roller and the screen plate.

Conversely, the insert plate 43 moves backward, the inclined surface of the blocking ramp block 34 gradually rises, and the pressure plate 32 rises under the action of the spring 42, so as to adjust the height of the pressure roller 31.

[0025] The pusher includes a screw sleeve 46 disposed in the middle of the frame plate 44 and a screw rod 47 threadedly connected to the screw sleeve 46. The screw rod 47 is rotatably mounted on the pusher seat 48, and a handle 5 is provided on the outside of the pusher seat 48 to control the rotation of the screw rod 47, so as to control the back-and-forth movement adjustment of the frame plate 44 by rotating the screw rod 47 through the handle.

[0026] A positioning gear 49 is fixedly mounted on the screw 47 between the push base 48 and the handle 5. A pin 40 is slidably mounted on the upper end of the push base 48, and the lower end of the pin 40 is inserted into the tooth groove of the positioning gear 49 to fix the positioning gear 49 and prevent the screw 47 from rotating arbitrarily. When the operator rotates the handle 5, the pin 40 can be pulled out, and after rotating to the designated position, the pin 40 can be inserted to lock the positioning gear 49.

[0027] In this embodiment, a bottom plate 11 is provided at the lower end of the cylinder 1, and a feed chamber for receiving particles is formed between the bottom plate and the screen plate 2. A cutter 12 is installed on the inner wall of the cylinder 1 at the upper end of the feed chamber to cut the particle column extruded from the lower end of the screen plate 2. An opening is provided on one side of the feed chamber, and a feed hopper 13 is installed at the outer end of the opening. A discharge component for discharging granular material is provided in the feed chamber. The discharge component includes a conical disk 14 fixedly installed at the outer end of the rotating shaft 21 and a discharge plate 15 annularly distributed at the outer end of the conical disk 14, so that the conical disk 14 and the discharge plate 15 are rotated by the rotating shaft 21, and the granular material is thrown into the feed hopper 13 for discharge.

[0028] The lower end of the rotating shaft 21 is mounted on the bearing seat 16 corresponding to the base plate 11. The first pulley 17 is mounted on the lower end of the rotating shaft 21 on the base plate 11. A drive motor 18 is mounted on one side of the transmission box 10. A second pulley 19 is mounted on the lower end of the drive motor 18 on the transmission box 10. The first pulley 17 and the second pulley 19 are connected by belt drive.

[0029] The working principle of this utility model is as follows: Material is fed into the upper part of the cylinder 1. The drive motor drives the rotating shaft 21 to rotate, which in turn drives the screen plate 2 to rotate. The pressure roller 31 interacts with the screen plate 2 to squeeze the material, so that the particle column is discharged from the screen hole at the lower end of the screen plate 2. The particle column is cut into particles by the cutter installed on one side of the cylinder 1, falls into the guide chamber, and is discharged through the discharge component. The operator controls the screw 47 to rotate by turning the handle, so as to control the back and forth movement of the frame plate 44, thereby driving the insertion plate 43 to move. The height of the pressure plate 32 is adjusted by using the inclined surface at the lower end of the insertion plate 43, so as to achieve precise adjustment of the gap between the pressure roller 31 and the screen plate 2.
