Description

Technical Field

[0001] The utility model relates to the technical field of crayfish farming in paddy fields, and specifically provides a feeding device for red claw crayfish farming in paddy fields. Background Technique

[0002] Crayfish farming in paddy fields means raising crayfish in paddy fields to make them coexist with rice. When farming crayfish in paddy fields, the paddy fields are dug into a ring-shaped or "field" - shaped ditch. The ring-shaped project is to dig a ring-shaped shrimp ditch with a width of 2 - 3 meters and a depth of 0.5 - 1 meter along the perimeter of the field ridge. A field ridge is built around the shrimp ditch to prevent water leakage. The ring-shaped ditch should be 1 - 1.5 meters away from the field ridge. At one end of the ring-shaped ditch, a shrimp temporary rearing pond with a width of 5 meters and a depth of 1.2 meters should be additionally dug. The "field" - shaped project means that while digging the ring-shaped ditch, a "+" - shaped shrimp ditch with a width of 2 meters and a depth of 0.5 - 0.7 meters is additionally dug in the middle of the field block, and this ditch is connected to the ring-shaped ditch.

[0003] For example, the patent with the national authorized patent publication number CN217905830U discloses a feeding device for red claw crayfish farming in paddy fields, including a box body, a feeding port and a discharging port. The feeding port and the discharging port are both arranged on the box body. It further includes: a feeding mechanism, which is arranged on the box body. The feeding mechanism includes a rotating rod, a spiral blade, a motor, a plurality of connecting rods and an airbag ring. The motor is fixed on the box body. The rotating rod is arranged inside the box body and fixed on the output shaft of the motor. The spiral blade is fixed on the rotating rod inside the discharging port. One end of each of the plurality of connecting rods is fixed on the box body and the other end is fixed on the airbag ring. When in use, it can easily move in the shrimp ditch, and the feed in the box body is continuously discharged through the discharging port, which can evenly put the feed into the shrimp ditch and also reduce the labor intensity of people.

[0004] However, the above - mentioned feeding device for red claw crayfish farming in paddy fields does not have an automatic spreading function during the process of feeding the feed, and still requires staff to push the device to complete the feeding work. This means that in large - scale farming, operators need to push the equipment for a long time, which affects work efficiency. Moreover, if the speed is uneven or the direction is inaccurate during the pushing process by the staff, it will also cause uneven distribution of the feed, thus affecting the feeding effect. Content of the Utility Model

[0008] Preferably, the pushing mechanism includes a motor, which is fixedly mounted on the lower surface of the connecting disk. The output shaft of the motor passes through the connecting disk and a first gear is fixedly mounted on the end thereof. The first gear is engaged with three sets of second gears. The second gear is fixedly mounted on the upper surface of the C-shaped disk. The C-shaped disk is rotatably mounted in a rotating groove. The rotating groove is provided in the connecting disk and is communicated with the pushing port.

[0009] Wherein, the first gear and the second gear both pass through the connecting disk and are rotatably mounted on the upper surface of the connecting disk.

[0010] Preferably, a connecting arm is rotatably mounted in the U-shaped disk, the other end of the connecting arm is rotatably mounted in a push post, and the push post is slidably mounted in the material pushing port.

[0011] Preferably, the U-shaped disc can drive the connecting arm to push and pull the push pin to slide back and forth in the pushing port;

[0012] Wherein, the push pin can block the pushing port during the process of being pushed in the pushing port;

[0013] The push column can expand the push port when being pulled in the push port, so that the feed in the red claw crayfish feed storage cylinder enters the push port through the first connecting port and the second connecting port and is pushed out.

[0014] Preferably, the first gear and the three sets of second gears are enclosed by a protective cover, and the protective cover is fixedly mounted on the upper surface of the connecting disk.

The pushing mechanism can be pulled and unfolded from the lower end of the pushing port during the process of being pulled in the pushing port, so that the feed in the red claw crayfish feed storage cylinder can fall into the pushing port through the first connecting port and the second connecting port. As the pushing mechanism continues to operate, the pushing mechanism will perform a pushing operation in the pushing port, which can The feed that falls into the pushing port is pushed and spread into the rice field, and this process is repeated. The distance the feed is pushed increases with the increase in the rotation speed of the pushing mechanism. The feed can be spread to different places by gradually reducing the rotation speed, so that the feed can be spread to all places. In this way, all the red claw crayfish can get the feed in a balanced manner, and there will be no situation where some shrimps cannot eat the feed because the feed is concentrated in a certain place. This ensures the uniform growth of the shrimp group. In addition, there is no need for staff to frequently move the equipment during the spreading process. After starting the equipment, the feed will be automatically spread, which reduces the frequency and intensity of manual feeding, greatly reduces the workload, and improves work efficiency.

[0018] 2. Through the design of the first gear, the second gear, the C-shaped disc, the connecting arm, the push post and the motor, when the feed needs to be spread, the first gear can be driven to rotate by starting the motor, and the first gear will engage the three sets of second gears on the outer surface of the transmission to rotate, and the rotation of the second gear can drive the C-shaped disc to rotate in the rotating groove, and the rotating C-shaped disc can drive the reciprocating push-pull push post of the connecting arm to slide back and forth in the push port, and the push post can expand the push port when being pulled in the push port, so that the feed in the red claw crayfish feed storage cylinder can fall into the push port through the first connecting port and the second connecting port, until the C-shaped disc drives the connecting arm to rotate back, and the feed in the push port can be pushed out by the connecting arm to achieve spreading;

[0019] The pushing speed of the push rod increases with the increase of the motor speed, and the high-speed motor can drive the push rod to push the feed quickly in the pushing port, which can push the feed farther. The speed can be reduced step by step to spread the feed to different places, so that it can achieve comprehensive coverage of the feed.

[0020] In the process of the first gear being driven to rotate, the first gear will drive the loose stick fixedly installed on the upper surface to rotate and stir in the red claw crayfish feed storage cylinder, which can effectively prevent the feed from accumulating into lumps in the red claw crayfish feed storage cylinder due to gravity or humidity, prevent the feed from being blocked at the first connecting port or the second connecting port, and ensure that the feed can flow smoothly into the pushing port.
