Abstract

The utility model relates to the technical field of breeding, in particular to a feed discharging device. Comprising a clamping jaw, a transmission structure and a power air cylinder. The number of the clamping jaws is two. The shape of the clamping claw corresponds to the outer edge of the discharging opening so that the clamping claw can be attached to the discharging opening. The transmission structure is connected with the discharging opening in a swinging mode. One end of the transmission structure is connected with the clamping jaw, and the other end of the transmission structure is connected with the power air cylinder in a swinging mode. When the output end of the power air cylinder stretches out or retracts, the transmission structure drives the clamping claw to be away from or close to the discharging opening.

Compared with the prior art, the single air cylinder is adopted as a power source, and therefore the problem that effective clamping cannot be achieved due to two air cylinders is effectively avoided.

Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of breeding, especially to a feed discharging device. BACKGROUND

[0002] With the continuous development of the breeding industry, people's demand for feed is increasing, which leads to the increasing demand for feed transportation. In order to facilitate the transportation of feed, large nylon bags are currently used to package feed. During the packaging process, the staff holds the nylon bag, puts the nylon bag on the discharge port of the feed bin, and controls the feed bin to discharge. When the nylon bag is full, the nylon bag is sent to the subsequent sealing equipment for sealing through the conveyor belt. However, in actual operation, in order to make the nylon bag as full as possible, the staff needs to slightly lift the nylon bag to make the nylon bag in a natural state of drooping. As the amount of feed in the nylon bag increases, the force required to lift the nylon bag also increases. Therefore, in order to reduce the workload of the staff, the discharge port of the feed bin is usually provided with a corresponding discharging device to clamp the nylon bag during the discharging process, so that the staff does not need to exert force, thereby effectively reducing the workload of the staff.

[0007] In actual operation, the output end of the power cylinder is controlled to extend, so that the corresponding clamping claw is driven away from the discharge port through the transmission structure, and a certain gap is formed between the clamping claw and the discharge port. Then, the staff holds a nylon bag, puts the bag opening of the nylon bag on the discharge port, and controls the output end of the power cylinder to retract, so that the corresponding clamping claw is driven to close to the discharge port through the transmission structure, and the clamping claw clamps the nylon bag on the discharge port.

DETAILED DESCRIPTION

[0018] The following is a specific embodiment of the utility model and further describes the technical scheme of the utility model in combination with the drawings, but the utility model is not limited to these embodiments.

[0019] A feed discharging device, comprising: clamping claws 1, a transmission structure 2, and a power cylinder 3. The power cylinder 3 is fixedly arranged on one side of the discharge opening. The number of clamping claws 1 is two. The two clamping claws 1 are arranged at the two ends of the discharge opening respectively. The two clamping claws 1 can cooperate with each other to form a ring that can be attached to the outer edge of the discharge opening. Specifically, the clamping claw 1 comprises a clamping body 11 and an auxiliary claw 12. The clamping body 11 is an approximately cuboid structure. The clamping body 11 is arranged along the long side of the discharge opening. The auxiliary claw 12 corresponds to the curved arc region of the discharge opening, and the auxiliary claw 12 is in a corresponding arc shape. The trigger rod 121 is arranged on the auxiliary claw 12. One end of the trigger rod 121 is fixedly connected with the auxiliary claw 12. The other end of the trigger rod 121 extends into the clamping body 11. The clamping body 11 is provided with a through slot corresponding to the trigger rod 121. Meanwhile, the trigger rod 121 is swingably connected with the clamping body 11, and a torsional spring is arranged between the trigger rod 121 and the clamping body 11. Thus, the trigger rod 121 and the clamping body 11 form a certain angle without external force.

[0020] The transmission structure 2 comprises a connecting part 21, a transmission rod 22, a support seat 23 and a mounting block 24. The support seat 23 is in a plurality, and the support seat 23 is fixedly connected with the discharge port. The support seat 23 is arranged on the same straight line. One end of the connecting part 21 is fixedly connected with the clamping body 11, and the other end is swingably connected with the discharge port through a support seat 23. The transmission rod 22 comprises a stable rod 221 and a sliding rod 222. The stable rod 221 penetrates through the support seat 23 and is rotatably connected with the support seat 23. Meanwhile, one end of the stable rod 221 is fixedly connected with the connecting part 21. The sliding rod 222 is arranged at the end of the stable rod 221 away from the connecting part 21, and one end of the sliding rod 222 is slidably connected with the stable rod 221. Thus, the stable rod 221 and the sliding rod 222 are combined into an L-shaped structure. The mounting block 24 is fixedly connected with the output end of the power cylinder 3. The mounting ears 241 are further fixedly arranged on both sides of the mounting block 24. The end of the sliding rod 222 away from the stable rod 221 is swingably connected with the mounting ear 241. Thus, one end of the transmission rod 22 is fixedly connected with the connecting part 21, and the other end is swingably connected with the power cylinder 3.

[0021] In the actual state, in order to fully set the nylon bag on the discharge port, the discharge port is usually designed to be relatively long and narrow, otherwise the nylon bag will have a certain degree of wrinkles, which will affect the fit of the nylon bag and the discharge port, and then affect the subsequent operation.

[0022] When it is necessary to hold the feed, the output end of the power cylinder 3 is controlled to extend. At this time, under the drive of the power cylinder 3, the mounting block 24 moves downward along the vertical direction, thereby driving the end connected with the sliding rod 222 to move downward along the vertical direction, and further making the sliding rod 222 swing around the stable rod 221. In the process of swinging of the sliding rod 222, the sliding rod 222 rotates relative to the mounting ear 241, and at the same time, the sliding rod 222 slides relative to the stable rod 221. Thus, the aforementioned swinging process can be normally carried out. When the sliding rod 222 swings, the sliding rod 222 drives the stable rod 221 to rotate, and further drives the connecting part 21 to swing relative to the discharge port by the stable rod 221. Thus, the two clamping claws 1 are driven to move away from the discharge port by the corresponding connecting part 21. When the clamping claw 1 moves away from the discharge port, the trigger rod 121 will lose the extrusion of the discharge port, so that the elastic force accumulated by the torsional spring is released, thereby driving the trigger rod 121 to further swing the auxiliary claw 12, and further making the auxiliary claw 12 further move away from the discharge port. Otherwise, due to the existence of a certain tangent area between the auxiliary claw 12 and the arc part of the discharge port, based on the action direction of the clamping claw 1, the auxiliary claw 12 cannot be fully separated from the discharge port, which affects the subsequent operation of the worker.

[0023] When the output end of the power cylinder 3 extends to the specified position, the clamping jaw 1 is fully separated from the discharge port. At this time, the worker can open the bag opening of the nylon bag and put the nylon bag on the discharge port. Then, the output end of the power cylinder 3 is controlled to retract, so that the above-mentioned process is reversed, and the clamping jaw 1 is close to the discharge port, so as to clamp the nylon bag on the discharge port. On the other hand, during the clamping process, the trigger lever 121 gradually approaches the discharge port, when the trigger lever 121 is in close contact with the discharge port, the clamping body 11 is still close to the discharge port, so that the discharge port gradually extrudes the trigger lever 121, and the trigger lever 121 drives the auxiliary jaw 12 to swing relative to the clamping body 11. At the same time, the torsional spring accumulates elastic force again. Finally, when the clamping body 11 is fully in close contact with the discharge port, the auxiliary jaw 12 is fully in close contact with the arc part of the discharge port. Thus, the clamping jaw 1 can effectively clamp the nylon bag on the discharge port.

[0024] In summary, the utility model can complete the clamping operation of the nylon bag through only one power cylinder 3. The problem that the nylon bag cannot be effectively clamped due to the inconsistent action and inconsistent stroke of the two cylinders is effectively avoided. At the same time, the trigger lever 121 can make the auxiliary jaw 12 further away from the discharge port, so as to facilitate the worker to operate.

Those skilled in the art to which the utility model belongs can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the utility model or exceed the range defined by the appended claims.
