Description

Technical Field

[0001] This utility model relates to the field of pellet mill technology, and more specifically, to an anti-clogging discharge mechanism for a feed pellet mill. Background Technology

[0002] In the field of feed production and processing, feed pellet mills are the core equipment for transforming feed raw materials from powder or loose form to pellet form. Pelleted feed can not only reduce the loss of raw materials during transportation and reduce the risk of moisture absorption and clumping during storage, but also improve the palatability and digestibility of animals by optimizing the pellet density. Therefore, pellet mills are widely used in large-scale feed mills.

[0003] The utility model patent with announcement number CN215775446U discloses a new type of feed pellet mill cooler uniform feeding device, including a pellet mill body, a feed cooler shell and a uniform feeding mechanism. In the process of use, when the motor is started, the wet and hot feed produced by the pellet mill body is fed into the conical guide block in the feed cooler shell through the feed pipe. The rotation of the motor drives the rotation of the shaft, which in turn drives the rotation of the conical guide block. The rotating conical guide block can make the feed spread out in the pellet mill body and fall to the bottom plate for cooling, avoiding local accumulation of material that affects cooling and dehumidification.

[0004] Although this utility model makes the material distribution more uniform, thereby improving the feed production rate, the discharge mechanism is only a single straight pipe structure. When the feed is discharged, if it is blocked due to adhesion, a small amount of irregular broken particles or incompletely granulated powder, the machine needs to be stopped and manually disassembled and cleaned. This not only interrupts production and reduces daily output, but may also cause wear on the inner wall of the discharge channel due to forced cleaning, shortening the service life of the equipment. Utility Model Content

[0005] The purpose of this invention is to provide an anti-clogging discharge mechanism for a feed pellet mill to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A feed pellet mill anti-clogging discharge mechanism includes a discharge channel, the discharge channel being generally rectangular in shape, and further includes:

[0008] A vibration mechanism is provided in the discharge channel near the top. The vibration mechanism includes a screen plate that vibrates up and down continuously. The screen plate has a number of screen holes regularly opened. Fixed plates extending outside the discharge channel are fixed to the four corners of the screen plate. Mounting plates are fixed to the outer wall of the discharge channel below each of the fixed plates. Springs are installed between the upper and lower adjacent mounting plates and the fixed plates.

[0009] An intermittent mechanism is arranged in the discharge channel close to the bottom end, which comprises an intermittently rotating rotating rod, which is rotationally connected between the left and right side walls of the discharge channel, and a plurality of partitions are regularly fixed on the outer side wall of the rotating rod.

[0010] As a preferred, one end of the rotating rod extends to the outside of the discharge channel and is fixed with a grooved wheel, and the positions of the radial grooves of the grooved wheel correspond one-to-one to the positions of the partitions;

[0011] As a preferred, a motor is fixed on the outer side wall of the discharge channel close to the grooved wheel, and a dial is coaxially connected to the output shaft of the motor and cooperates with the grooved wheel;

[0012] In the two settings, the position correspondence relationship between the grooved wheel and the partition ensures that the partition can accurately and synchronously displace every time the rotating rod completes a rotation, so that the rhythm of batch feeding is always uniform, and the problem of local accumulation of feed in the channel caused by deviation of the rotating angle of the partition is effectively avoided; at the same time, the motor drives the grooved wheel to rotate through the dial, which can convert the continuous power output by the motor into intermittent motion of the rotating rod, improving the stability of intermittent feeding action.

[0013] As a preferred, a connecting plate is fixed in the middle of the left and right side walls of the sieve plate, the connecting plate extends to the outside of the discharge channel, and the bottom surface of one end of the connecting plate located outside the discharge channel is fixed with a control plate, and an arc groove is formed in the bottom surface of the control plate;

[0014] As a preferred, a rotating shaft is rotationally connected below the connecting plate of the discharge channel, eccentric wheels are fixed on the outer side walls of both ends of the rotating shaft, the top ends of the eccentric wheels are in contact with the arc grooves of the same side control plate, and the rotating shaft and the output shaft of the motor are connected through a belt drive;

[0015] As a preferred, a limiting groove corresponding in position and size to the fixed plate is formed in the left and right side walls of the discharge channel, and a baffle is fixed on each of the four corners of the top and bottom surfaces of the sieve plate;

[0016] As a preferred, a limiting groove corresponding in position and size to the connecting plate is formed in the left and right side walls of the discharge channel, and a baffle block is fixed on the middle of the left and right ends of the top and bottom surfaces of the sieve plate;

[0017] Among the four settings, the cooperation of the rotating shaft and the eccentric wheel can convert the rotating action into the up-down reciprocating vibration of the sieve plate, and then through the linkage of the belt and the motor, a single motor can drive the vibration mechanism and the intermittent mechanism at the same time, the number of power elements is reduced, the overall structure of the equipment is more compact, the movement track of the fixed plate can be constrained by the limiting groove, and the sieve plate is prevented from colliding with the inner wall of the discharging channel when vibrating left and right, and the baffle can completely block the gap of the limiting groove to avoid feed leakage.

[0018] As preferred, the movable door is hinged at the front side wall of the discharging channel near the sieve plate, and a handle is fixed to the front side of the movable door away from the hinged end;

[0019] In this setting, the handle can quickly open the movable door, and the large raw materials or impurities trapped on the sieve plate can be directly cleaned without disassembling the entire discharging channel, which greatly shortens the time cost of cleaning and maintenance.

[0020] Compared with the prior art, the utility model has the advantages that:

[0021] 1. In the utility model, the vibration mechanism passes through the sieve plate vibrating up and down, which can perform preliminary screening on the just finished granulation feed on one hand: qualified particles pass through the sieve hole into the downstream channel, while large raw materials or impurities that are not completely granulated are intercepted to avoid blockage caused by size mismatch after entering the channel; on the other hand, the continuous vibration of the sieve plate can break the adhesion tendency of the feed particles, prevent the particles from accumulating at the top of the discharging channel, and ensure uniform downward conveying of the raw materials.

[0022] 2. In the utility model, the intermittent mechanism realizes the intermittent rotation of the rotating rod through the cooperation of the groove wheel and the dial, when the dial drives the groove wheel to rotate, the partition plate on the rotating rod rotates synchronously, which batches and uniformly conveys the feed particles in the channel downward, which not only ensures the stability of the discharging amount, but also further reduces the retention probability of the particles in the channel.
