Description

Technical Field

[0001] This utility model belongs to the field of feed production and processing technology, and specifically relates to a pelleting device for livestock feed. Background Technology

[0002] A pelleting device for livestock feed is a type of feed processing equipment used to process feed ingredients into pellets, making the feed ingredients more compact and easier for animals to digest and absorb, thereby improving feed conversion rate.

[0003] In simple terms, under the influence of gravity, feed ingredients are fed through the feed hopper onto two extruder rollers. Through the rotation of the pressure rollers and the extrusion through the die holes, they are gradually formed into granules. However, since feed ingredients such as grains and soybean meal contain a certain amount of dust, this dust is easily released during the crushing and mixing process. In addition, the feed hoppers of some existing livestock feed pelleting devices are usually open, which causes dust to fly around, polluting the working environment and affecting the health of users. Moreover, impurities can also enter the feed ingredients from the open feed hopper, affecting the purity and quality of the feed. Therefore, a livestock feed pelleting device is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a pelleting device for livestock feed to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pelleting device for livestock feed, comprising:

[0006] The main body of the device includes a feeding hopper, a pressure roller, and a mold plate. The feeding hopper is fixedly installed on the upper end face of the mold plate, and the pressure roller is rotatably installed between the feeding hopper and the mold plate, with the circumferential side of the pressure roller in contact with the mold plate.

[0007] A dustproof assembly includes a dustproof plate, a rotating shaft, spring plates, and a limiting plate. A pair of dustproof plates and rotating shafts are provided, with the pair of rotating shafts fixedly installed parallel to each other at the upper end of the feed hopper. The pair of dustproof plates are rotatably connected to the pair of rotating shafts. Two sets of spring plates are provided, with their two ends connected to the lower end face of the dustproof plate and the inner wall of the feed hopper, respectively. The limiting plate is fixedly installed at the upper end of the feed hopper, and the pair of rotating shafts are symmetrically distributed about the axial direction of the limiting plate.

[0008] As a preferred embodiment, the dustproof assembly further includes a water inlet pipe and water spray components. Multiple water spray components are provided, and the multiple water spray components are installed at intervals on the water inlet pipe and connected to the water inlet pipe. The water inlet pipe is fixedly installed on the upper end face of the feed hopper, and the limiting plate is fixedly installed on the water inlet pipe.

[0009] As a preferred embodiment, the limiting plates are provided in pairs, with one end of each pair of limiting plates fixedly installed on the circumferential side of the water inlet pipe, and the pair of limiting plates are symmetrically distributed with the axial direction of the water inlet pipe as the center.

[0010] As a preferred embodiment, the dustproof assembly further includes corrugated pipes, which are provided in two sets, with multiple corrugated pipes in each set. The multiple corrugated pipes in each set are installed at intervals on the lower end face of each limiting plate. The limiting plate is hollow, and the corrugated pipes are connected to the hollow limiting plate.

[0011] As a preferred embodiment, the pair of dustproof plates are configured in an L-shape at opposite ends, with the upper end face of the dustproof plate fitting against the lower end face of the corrugated pipe.

[0012] As a preferred embodiment, the water inlet pipe has a through hole on the side connected to the limiting plate, and the through holes are arranged in multiple ways and spaced apart.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention features a dustproof assembly comprising a dustproof plate, a rotating shaft, a spring plate, and a limiting plate. The rotating shaft is mounted on the feed hopper, and the dustproof plate is rotatably connected to the rotating shaft. The spring plate connects the dustproof plate and the feed hopper, and the limiting plate is fixedly mounted on the upper end of the feed hopper. When the user places feed ingredients on the upper surface of the dustproof plate, the dustproof plate rotates from a horizontal to a downward tilted state around the axis of the rotating shaft, causing the feed ingredients to fall from the upper surface of the dustproof plate onto the mold plate. Under the restoring force of the spring plate, the dustproof plate changes from an inclined state to a horizontal state. This effectively blocks dust, preventing it from flying and preventing impurities from entering the feed hopper, thus ensuring the purity and quality of the feed.

[0015] This invention comprises a water inlet pipe, water spray components, and corrugated pipes. Multiple water spray components are spaced apart on the water inlet pipe, which is fixedly installed on the upper end face of the feed hopper. A limiting plate is fixedly installed on the water inlet pipe. Multiple corrugated pipes are spaced apart on the lower end face of each limiting plate, which is hollow. The corrugated pipes are connected to the hollow limiting plates. When the dustproof plate changes from an inclined state to a horizontal state, the corrugated pipes are compressed by the rotating dustproof plate, thereby forcing gas from inside the limiting plate into the water inlet pipe through a through hole. This allows the liquid in the water inlet pipe to enter the feed hopper through the water spray components. In this way, the sprayed liquid further prevents dust from flying, and the liquid mixes with the feed, keeping the feed moist and making it easier for it to fall from the mold holes of the mold plate.

The two ends of the spring plate 23 are respectively connected to the lower end face of the dustproof plate 21 and the inner wall of the feed hopper 11. The limiting plate 24 is fixedly installed at the upper end of the feed hopper 11, and the pair of rotating shafts 22 are symmetrically distributed with the axis of the limiting plate 24 as the center.

[0026] The dustproof component 2 also includes a water inlet pipe 25 and a water spray component 26. Multiple water spray components 26 are provided, and multiple water spray components 26 are installed at intervals on the water inlet pipe 25 and connected to the water inlet pipe 25. The water inlet pipe 25 is fixedly installed on the upper end face of the feed hopper 11, and the limiting plate 24 is fixedly installed on the water inlet pipe 25.

[0027] A pair of limiting plates 24 are provided. One end of the pair of limiting plates 24 is fixedly installed on the circumferential side of the water inlet pipe 25, and the pair of limiting plates 24 are symmetrically distributed with the axial direction of the water inlet pipe 25 as the center.

[0028] The dustproof component 2 also includes a bellows 27. There are two sets of bellows 27, and each set of bellows 27 has multiple bellows 27. The multiple bellows 27 in each set are installed at intervals on the lower end face of each limiting plate 24. The limiting plate 24 is hollow, and the bellows 27 are connected to the hollow limiting plate 24.

[0029] A pair of dustproof plates 21 are configured in an L-shape at opposite ends, with the upper end face of the dustproof plate 21 attached to the lower end face of the corrugated pipe 27;

[0030] The water inlet pipe 25 has a through hole 251 on the side connected to the limiting plate 24. Multiple through holes 251 are provided and are spaced apart.

[0031] Working principle and usage process of this utility model:

[0032] In the initial state, the upper end face of a pair of dustproof plates 21 is attached to the lower end face of the corrugated pipe 27. At this time, the dustproof plates 21 are in a horizontal state, and the upper end face of the dustproof plates 21 is attached to the lower end face of the limiting plate 24, so that the upper port of the feed hopper 11 is sealed by a pair of dustproof plates 21; and one end of the water inlet pipe 25 is connected to a container filled with liquid and a water pump.

[0033] During use, the user places the feed material on the upper surface of the dustproof plate 21. Under the gravity of the feed material, the dustproof plate 21 rotates from a horizontal state to a downward tilting state around the axis of the rotating shaft 22. At this time, the spring plate 23 is compressed, causing the feed material to fall from the upper surface of the dustproof plate 21 onto the mold plate 13. Subsequently, the rotating pressure roller 12 grinds and presses the feed material, and finally the granular feed flows out of the lower surface of the mold plate 13 through the mold holes on the mold plate 13.

[0034] After the feed material falls, the spring plate 23 causes the dustproof plate 21 to change from an inclined state to a horizontal state. In this way, the dust generated by the feed material being ground and pressed by the pressure roller 12 is blocked by the horizontal dustproof plate 21 and will not escape from the upper port of the feed hopper 11. This not only prevents dust from flying, but also prevents impurities from entering the feed hopper 11 through the upper port of the feed hopper 11, ensuring the purity and quality of the feed.

[0035] Furthermore, when the dustproof plate 21 changes from an inclined state to a horizontal state, the bellows 27 is compressed by the rotating dustproof plate 21, thereby forcing the gas from inside the limiting plate 24 into the water inlet pipe 25 through the through hole 251, so that the liquid in the water inlet pipe 25 enters the feed hopper 11 through the water spraying element 26. In this way, the sprayed liquid further prevents dust from flying, and the liquid mixes with the feed, keeping the feed moist and making it easier for it to fall from the mold hole of the mold plate 13.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
