Description

Technical Field

[0001] The invention relates to the technical field of sturgeon breeding, and in particular to a feed spreading device for sturgeon breeding. Background Art

[0002] Sturgeon is a general term for fish of the order Acipenseriformes, found in the oceans and rivers of the Northern Hemisphere, with nine natural distribution areas. They are the largest, longest-lived, and oldest fish in the world, with a history of over 200 million years. Sturgeon farming technology involves multiple aspects, including site selection, facility construction, feed selection and feeding, water quality management, and disease prevention. The choice of feed is mainly based on compound feeds, and feeding should adhere to the principle of small, frequent meals. Feed should be palatable, with particle size not too large or too small, generally 1 / 2 the size of a fish's mouth cleft. The feeding amount is about 3% of the fish's body weight, 3-4 times a day, and the feeding amount can be adjusted at any time depending on the specific situation. Existing technologies make it difficult to quantitatively feed, and thus difficult to accurately control the sturgeon's food intake.

[0003] Patent publication number CN213463470U discloses an efficient feeding device for large-scale sturgeon farming. The upper end of the support column of the patent is provided with a rotating drum, and the upper end of the rotating drum is provided with a material barrel. The upper end of the material barrel is fixedly connected to a protective shell, and the outer wall of the material barrel is provided with a feed inlet. The upper end of the protective shell is installed with a shielding component. A motor is installed inside the protective shell, and the bottom of the motor is fixedly connected to a motor gear. In normal times, the fish should be prevented from being injured. Therefore, when feeding, the feed should not be thrown too concentratedly, and the mutual influence of the fish when feeding is reduced. The use of the rotating drum can evenly spread the feed, which is conducive to reducing the occurrence of diseases. Sturgeons are different from ordinary fish in that their light requirements will vary. When the temperature is high in summer, direct sunlight into the water will affect the development of sturgeons. Therefore, a shielding component can be used for sunshade, and it can be stored at any time and is easy to operate. Although the patent solves the above problems, it is still difficult to feed in a fixed quantity and thus difficult to accurately control the amount of food consumed by the sturgeons. Therefore, a feed throwing device for sturgeon farming is proposed to solve the above problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a feed spreading device for sturgeon farming in view of the deficiencies in the above-mentioned prior art.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a feed spreading device for sturgeon farming, comprising a feed barrel, a transmission housing is fixedly connected to the left side of the feed barrel, a feeding sleeve is fixedly connected to the right side of the transmission housing, a discharge barrel is hingedly connected to the right inner surface of the feed barrel, a discharge port is provided on the upper surface of the discharge barrel, a feeding roller is fixedly connected to the left side of the discharge barrel, a feeding port is provided on the rear side of the feeding roller, a main shaft is rotatably connected to the left inner surface of the transmission housing, an annular clamping plate is fixedly connected to the left side of the inner wall of the feed barrel, and the feeding roller The left side of the feed barrel is fixedly connected with a fan-shaped resistance block, the circumferential surface of the main shaft is fixedly connected with a toggle plate, the rear side of the feed barrel is fixedly connected with a mounting plate, and a telescopic feeding device for adjusting the feeding distance is provided below the feed barrel, which is convenient for feeding different fish ponds. A dredging device for dredging the telescopic feeding frame and improving the feeding efficiency is provided below the feed barrel. The upper surface of the feeding sleeve is fixedly connected to the lower surface of the feed barrel, the circumferential surface of the feeding roller and the inner surface of the annular clamping plate are hinged, the left end of the main shaft is fixedly connected with a motor, and the motor and the upper surface of the mounting plate are fixedly connected. The front side of the feeding drum and the front side of the inner wall of the feeding drum contact each other, the top of the toggle plate and the inclined surface of the fan-shaped resistance block contact each other, and a torsion spring is provided at the hinge of the discharge drum and the feeding drum. The feed is poured into the discharge drum through the discharge port, and the feed then falls from the discharge drum into the feeding drum. The discharge drum is rotated backward, and the discharge drum drives the feeding drum to rotate in the feeding drum. After the feeding drum rotates a certain angle so that the discharge port faces downward, the feed in the feeding drum falls into the feeding drum through the discharge port, and then slides through the arc surface of the inner wall of the feeding drum into the feeding sleeve for feeding, and then the elastic reset effect of the torsion spring drives the discharge drum and the feeding drum to rotate. Reset, at this time the feeding port faces backward, the feed in the feeding drum cannot fall into the feeding bucket, start the motor, the motor drives the main shaft to rotate, the main shaft drives the toggle plate to rotate, the toggle plate pushes it to rotate backward along the axis of the feeding drum through the inclined surface of the fan-shaped resistance block, and the fan-shaped resistance block drives the feeding drum to rotate backward in the feeding bucket when it rotates backward, so that the feeding port faces downward, and then the torsion spring drives the feeding drum and the feeding drum to rotate and reset. During the continuous rotation of the main shaft and the toggle plate, the feeding drum and the feeding drum are driven to rotate continuously and reset through the fan-shaped resistance block, so that the feed intermittently and automatically falls from the feeding drum into the feeding bucket and the feeding sleeve.

[0006] The lifting mechanism is connected with the lifting mechanism, and the lifting mechanism is connected with the lifting mechanism, and the lifting mechanism is connected with the lifting mechanism of the lifting mechanism is connected with the lifting mechanism of the lifting mechanism. The left side of the telescopic feeding frame rotates and passes through the left side of the inner wall of the telescopic feeding frame. The circumferential surface of the feeding roller and the inner surface of the annular partition contact each other, and the left side of the nut is fixedly connected to the left side of the inner wall of the telescopic feeding frame. The feed that slides out of the feed bucket is caught by the telescopic feeding frame. At this time, the staff can adjust the distance between the feeding port opened on the telescopic feeding frame and the feeding sleeve by pulling out or pushing the telescopic feeding frame into the feeding sleeve. When the telescopic feeding frame is pulled out of the feeding sleeve, the electric telescopic rod is started. After the free end of the electric telescopic rod is extended, the transmission sleeve is lifted to the right through the mounting plate. The transmission sleeve then drives the feeding sleeve and the telescopic feeding frame to tilt to the right. After the telescopic feeding frame is tilted, the feed can slide to the lower right, and the rotation of the main shaft drives the reciprocating screw to rotate. The reciprocating screw drives the nut to move back and forth left and right. The nut drives the telescopic feeding frame to slide back and forth left and right in the feeding sleeve, so that the telescopic feeding frame can automatically extend and retract into the feeding sleeve.

[0007] The camming member is a pair of armchairs, each of which is connected to the guide rail by a toothed connection, and the guide rail is connected to the guide rail by a toothed connection. The connecting rod rotates along the circumference of the telescopic slide rod axis, and the connecting rod drives the cleaning roller to rotate along the circumference of the telescopic slide rod axis and generates friction with the inner wall of the telescopic feeding frame. The cleaning roller pushes the feed blocked near the feeding port out of the feeding port through friction. When the nut moves to the right, it drives the transmission ring to move to the right, and the transmission ring drives the resistance rod to move to the right. The resistance rod pushes it to the right by contacting with the connecting plate and the resistance semicircular plate. The connecting plate drives the telescopic slide rod to slide to the right in the reciprocating screw. At the same time, the connecting plate drives the connecting rod and the cleaning roller to move to the right. When the nut moves to the left, it drives the transmission ring and the resistance rod to move to the left. The nut also drives the telescopic feeding frame to move to the left. At this time, the inner wall of the telescopic feeding frame pushes the connecting rod and the cleaning roller to move to the left, the connecting rod drives the connecting plate to move to the left, and the connecting plate drives the telescopic slide rod to slide to the left in the reciprocating screw, so that the cleaning roller is always consistent with the feeding port.

[0008] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0009] 1. In the feed spreading device for sturgeon farming, the elastic reset action of the torsion spring drives the discharge barrel and the feeding drum to rotate and reset. At this time, the feeding port faces backward, and the feed in the feeding drum cannot fall into the feeding bucket, which facilitates quantitative feeding and prevents waste caused by feeding too quickly. The feeding drum and the discharge barrel continue to rotate and reset, so that the feed intermittently and automatically falls from the feeding drum into the feeding bucket and feeding sleeve, avoiding feed waste and improving feeding efficiency.

[0010] 2. With the feed spreading device for sturgeon farming, workers can adjust the distance between the feeding port on the telescopic feeding frame and the feeding sleeve by pulling out or pushing the telescopic feeding frame into the feeding sleeve, thereby adjusting the feeding distance, making it convenient to feed at different positions in the fish pond and improving the applicability of the device. After the telescopic feeding frame is tilted, the feed can slide to the lower right, which is convenient for long-distance feed feeding and improves the ease of use of the device. The telescopic feeding frame can automatically extend and retract into the feeding sleeve, thereby evenly feeding the feed to various positions in the fish pond and improving the feeding efficiency.

[0011] 3. In the feed spreading device for sturgeon farming, the cleaning roller pushes the feed blocked near the feeding port out of the feeding port through friction, thereby improving feeding efficiency and avoiding insufficient feed due to blockage of the telescopic feeding frame in a certain part of the fish pond, thereby improving feeding uniformity. The connecting plate drives the telescopic slide rod to slide to the left in the reciprocating screw, so that the cleaning roller is always consistent with the feeding port, further preventing blockage of the feeding port and improving the dredging effect.
