Drum-type multi-stage sorting device for crayfish

Abstract

The drum-type multi-stage sorting device comprises a drum-type multi-stage screening machine, a material guiding groove body is arranged at the position of a discharging opening in the drum-type multi-stage screening machine, a material collecting box is arranged at the lower end of the material guiding groove body, and an adjusting supporting frame is installed on the outer wall of the material guiding groove body. According to the drum-type multi-stage sorting device for the crayfish, the crayfish slowly slides down along the plate face through the arranged material guide groove body, impact force is reduced, the angle of the material guide groove body is convenient to adjust through the arranged adjusting supporting frame, and when the rotating speed of the drum or the flow of the crayfish changes (for example, the load is increased in the peak period), the crayfish can be separated from the material guide groove body. The angle of the guide plate can be adjusted to adapt to different sorting speeds and material quantities; the angle is increased (steeper), the discharging speed can be increased, and accumulation is prevented; the angle is reduced (more gentle), the sliding speed is reduced, and damage is reduced.

Description

Technical Field

[0001] This utility model relates to the field of crayfish processing technology, specifically a drum-type multi-stage sorting device for crayfish. Background Technology

[0002] Crayfish need to be sorted during processing to grade them by size for easier subsequent handling or sale. Currently, drum-type multi-stage screening machines are commonly used sorting equipment, which achieves the sorting of crayfish through the rotation of the drum and the grading action of the sieve holes.

[0003] However, the existing technology has the following problems:

[0004] 1. High damage rate: Crayfish fall directly and at high speed from the drum discharge port and collide with the collection box or other parts of the equipment, which can easily lead to broken claws, broken shells and other damage, affecting product quality and economic value.

[0005] 2. Poor adaptability: The guide structure of existing equipment is mostly at a fixed angle, which cannot flexibly adjust the feeding speed according to the drum speed or changes in crayfish flow (such as increased load during peak processing periods). This can easily cause material to accumulate or slide too fast, further increasing the risk of damage.

[0006] Therefore, we propose a drum-type multi-stage sorting device for crayfish. Utility Model Content

[0007] (a) Technical problems to be solved

[0008] To address the shortcomings of existing technologies, this utility model provides a drum-type multi-stage sorting device for crayfish. The guide plate has an adjustable tilt angle (usually 30°~60°) to allow the crayfish to slide slowly down the plate surface, reducing impact. When the drum speed or crayfish flow rate changes (such as increased load during peak periods), the angle of the guide plate can be adjusted to adapt to different sorting speeds and material quantities, effectively solving the problems in the background technology.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a drum-type multi-stage sorting device for crayfish, comprising a drum-type multi-stage screening machine, wherein a guide trough is provided at the discharge port of the drum-type multi-stage screening machine, a collection box is provided at the lower end of the guide trough, and an adjusting support frame is installed on the outer wall of the guide trough. The adjusting support frame includes a base plate, a first support plate, a second support plate, a first driven shaft, a transmission box, a second driven shaft, a motor, a rotating shaft, a worm and a worm wheel, and the first driven shaft is fixedly installed in the middle of one side of the outer surface of the guide trough, and the second driven shaft is fixedly installed in the middle of the other side of the outer surface of the guide trough.

[0011] Preferably, the first support plate is fixedly installed at one end of the upper outer surface of the substrate, and the second support plate is fixedly installed at the other end of the upper outer surface of the substrate.

[0012] Preferably, a bearing is provided between the first driven shaft and the first support plate, and the first driven shaft is rotatably connected to the first support plate through the bearing.

[0013] Preferably, the transmission box is fixedly installed on the upper part of the outer wall of the second support plate, and a bearing is provided between the second driven shaft and the transmission box and the second support plate. The second driven shaft is rotatably connected to the transmission box and the second support plate through the bearing.

[0014] Preferably, both the worm and the worm wheel are located inside the transmission box. The worm wheel is fixedly installed on the outer wall of one end of the second driven shaft. The worm is located on the lower outer surface of the worm wheel, and the upper outer surface of the worm meshes with the lower outer surface of the worm wheel.

[0015] Preferably, a bearing is provided between the rotating shaft and the transmission box, the rotating shaft is rotatably connected to the transmission box through the bearing, a coupling is provided between the rotating shaft and the motor, and the outer surface of one end of the rotating shaft is fixedly connected to the outer surface of one end of the output shaft of the motor through the coupling.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a drum-type multi-stage sorting device for crayfish, which has the following beneficial effects:

[0018] 1. This is a roller-type multi-stage sorting device for crayfish. Through the set guide trough, the crayfish slide slowly down the inclined plate surface, reducing the impact force of direct fall, significantly reducing damage such as broken claws and broken shells, and improving product integrity and economic value.

[0019] 2. This is a drum-type multi-stage sorting device for crayfish. The adjustable support frame allows for easy adjustment of the angle of the feed trough. When the drum speed or crayfish flow rate changes (such as increased load during peak periods), the angle of the guide plate can be adjusted to adapt to different sorting speeds and material quantities. Increasing the angle (steeper) can speed up the feeding speed and prevent accumulation; decreasing the angle (gentler) reduces the slippage speed and minimizes damage. Attached Figure Description

[0029] It should be noted that this utility model is a drum-type multi-stage sorting device for crayfish. The drum-type multi-stage screening machine 1 described herein is prior art and can be readily understood by those skilled in the art; therefore, further details are omitted. In the drum-type multi-stage screening machine 1, a set of guide troughs 2 is provided at each feeding port. The crayfish are guided through the guide troughs 2 and collected by the collection box 3, allowing them to slide slowly down the plate surface, reducing impact. The adjustable support frame 4 facilitates adjustment of the guide troughs. The angle of the guide trough 2 is adjusted by the rotation of the motor 11, which drives the rotating shaft 12 and the worm gear 13 to rotate. The worm gear 13 drives the second driven shaft 10 to rotate through the worm wheel 14. The second driven shaft 10 drives the guide trough 2 to rotate, so that the angle of the guide trough 2 can be adjusted. When the drum speed or the crayfish flow rate changes (such as increased load during peak periods), the angle of the guide plate can be adjusted to adapt to different sorting speeds and material quantities. Increasing the angle (steeper) can speed up the feeding speed and prevent accumulation; decreasing the angle (gentler) can reduce the slippage speed and reduce damage.
