Description

Technical Field

[0001] The invention relates to the technical field of breeding pigs, and in particular to a feeding device used for breeding pigs. Background Art

[0002] With the rapid development of society, people's living standards are constantly improving, and animal husbandry has also entered a stage of rapid development. The scale and intensiveness of my country's pig farming industry are constantly improving, and the automation requirements of animal husbandry are getting higher and higher. The scale and intensive development of the breeding industry is particularly important. Artificial breeding methods have become increasingly difficult to meet the requirements of low cost, high efficiency, and safety of animal husbandry. Pig feed includes corn, rice, barley, millet, sorghum, buckwheat, etc. In actual breeding, the nutrients in corn, especially energy and protein, need to be crushed to increase the contact area with digestive enzymes so that they can be better absorbed by pigs. Uncrushed corn particles will reduce the digestion and absorption rate of nutrients.

[0003] According to a Chinese patent with the publication number "CN219330355U", a feeding device for breeding pigs is disclosed, which involves solving the problem that the feeding device cannot adjust the proportion of feed ingredients and needs manual mixing. It includes a support frame, a trough is fixedly installed at the bottom of the support frame, a water pipe is installed at one end of the support frame, and a regulating structure is fixedly installed on the top of the support frame. The regulating structure is used to regulate the proportion of ingredients in the pig feed. The utility model sets a regulating structure, and each component of the feeding feed is put into the feeding trough respectively. The capacitive proximity sensor display on the outer wall of the feeding trough senses the weight of the feed inside the feeding trough through the change of capacitance, thereby sending an electrical signal to the electric controller; the electric controller controls the electric push rod to move the movable block in the slotted fixing at different speeds, so that the feed in the feeding trough enters the feeding pipe in different quantities, thereby adjusting the proportion of the feed, so that the pigs can get sufficient nutrition in the growth stage, so that the breeding of the pigs is basically guaranteed.

[0004] The above patent mixes multiple feeds by rotating the mixing roller during use, but when corn kernels are used as feed, they cannot be crushed. If the uncrushed corn is directly eaten by breeding pigs, it will affect the digestion and absorption rate of the breeding pigs. Therefore, a feeding device for breeding pigs is proposed to solve the above problems. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a feeding device for breeding pigs in view of the deficiencies in the above-mentioned prior art.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: a feeding device for breeding sows, comprising a tank body, three feeding hoppers are fixedly connected to the top of the tank body, and are used to feed corn kernels and other feed into the tank body, a feed tray is fixedly connected to the bottom of the tank body through a support rod, and a crushing mechanism is arranged inside the tank body; The crushing mechanism includes a vertical shaft, a movable grinding plate, a fixed grinding plate, and a material drop hole; The bottom end of the vertical shaft is rotatably connected to the top of the feed plate through a bearing, the movable grinding disc is fixedly connected to the middle of the vertical shaft, the fixed grinding disc is fixedly connected to the inner wall of the tank body and is arranged above the movable grinding disc, and the corn kernels between the fixed grinding disc and the movable grinding disc are ground by relative movement, and the ground corn and other feeds will fall into the feed plate 4 through the bottom drop hole 504, the top end of the vertical shaft rotates through the fixed grinding disc through the bearing, and drop holes are opened on the movable grinding disc and the fixed grinding disc, the aperture of the drop hole at the top is larger than the aperture of the drop hole at the bottom, and kneading grooves are arranged at the top of the movable grinding disc and the bottom of the fixed grinding disc.

[0008] Preferably, a top block is fixedly connected to the top of the movable block, and the top block is spherical. Three sliding grooves are opened inside the movable grinding disc, and a slider is slidably connected inside the sliding groove. In the process of the movable block moving upward, it drives the top block to move upward and contact with the slider, pushing the slider upward, and the slider moves upward under the limiting action of the sliding groove and collides with the bottom of the fixed grinding disc and the top inner wall of the sliding groove, so that the fixed grinding disc and the movable grinding disc vibrate due to the collision, and the corn crushed materials blocked in the top kneading groove and the bottom kneading groove are shaken off, and the bottom of the slider contacts the top of the top block, and the up and down movement of the slider is limited by setting the sliding groove. A cleaning brush is fixedly connected to the other side of the slider away from the vertical axis, and the cleaning brush contacts with the kneading groove, and the corn crushed materials blocked in the kneading groove are crushed by setting the cleaning brush.

[0009] Preferably, a kneading mechanism is provided above the fixed grinding disc, and the kneading mechanism includes three horizontal shafts, and the three horizontal shafts are fixedly connected to the vertical shaft, and the external rotation of the three horizontal shafts is connected to the kneading rollers, when the vertical shaft rotates counterclockwise, the horizontal shafts are driven to rotate counterclockwise, and the kneading rollers are driven to rotate counterclockwise to knead the corn on the fixed grinding disc, and the kneading rollers are provided above the fixed grinding disc.

The front side of the movable plate is fixedly connected to bristles, and the bristles are in contact with the kneading roller. When the kneading roller rotates counterclockwise following the horizontal and vertical axes, it will contact the bristles on the front side of the movable plate, and the corn stuck to the surface of the kneading roller will be scraped off by the bristles, thereby promoting the kneading effect of the kneading roller.

[0013] Preferably, the bottom end of the feed pipe is rotatably connected to a second rotating shaft, and a semicircular plate is fixedly connected to the second rotating shaft. A vertical groove is opened on the outer side of the turntable, and the vertical groove and the lever are driven to rotate during the rotation of the turntable. When the vertical groove rotates to the bottom of the feed pipe, the turntable will break away from the contact with the bottom of the feed pipe. At this time, the corn and other feed in the three feeding hoppers will flow into the tank body through the feed pipe and fall onto the fixed grinding disc to achieve intermittent discharging. The inner wall of the vertical groove is fixedly connected to a lever, and the lever is in contact with the semicircular plate. The lever will collide with the semicircular plate during the rotation of the lever. The semicircular plate will flip over after the collision, and hit the corn and other feed falling in the feed pipe to make them scattered more evenly.

[0014] The present invention adopts the above technical solution to bring the following beneficial effects: 1. The invention provides a crushing mechanism, and grinds corn by means of a fixed grinding plate, a movable grinding plate and a kneading trough, so as to reduce the volume of corn, thereby making it easier for breeding pigs to digest when feeding.

The corn crumbs blocked in the kneading trough are scraped off by a cleaning brush, thereby further promoting the grinding effect of the fixed grinding plate and the movable grinding plate on the corn.

[0015] 2. The invention sets a kneading mechanism, and the vertical axis drives the horizontal axis and the kneading roller to rotate to knead the corn on the fixed grinding disc, thereby further reducing the volume of the corn. The pawl and the ratchet wheel are used to intermittently limit the rotation of the kneading roller, and the kneading roller is used to smooth the corn on the upper surface of the fixed grinding disc, thereby promoting the kneading effect of the kneading roller and stirring and mixing the corn with other feeds.

[0016] 3. The invention sets a feeding mechanism, and sets a movable plate, a vertical rod and a hinge. When the kneading roller rotates clockwise, it pushes the movable plate, and drives the vertical rod, the turntable, the vertical groove and the lever to rotate, and intermittently blocks the feeding pipe to achieve intermittent discharging. During the rotation of the lever, it will collide with the semicircular plate, and the semicircular plate will flip after the collision. When the corn kernels are synchronously mixed with other nutrients, such as other grains, these grains falling from the feeding pipe are hit to make them scattered more evenly, thereby promoting the mixing effect of multiple grains.

[0017] 4. The invention realizes the mutual cooperation between the kneading mechanism and the feeding mechanism. When the kneading roller rotates counterclockwise along the horizontal and vertical axes, it will contact the bristles on the front side of the movable plate, and the corn stuck to the surface of the kneading roller will be scraped off by the bristles, thereby promoting the kneading effect of the kneading roller.

When the movable block 506 moves upward, it drives the top block 508 to move upward and contact with the slider 5010, pushing the slider 5010 upward. The slider 5010 moves upward under the limiting action of the slide groove 509 and collides with the bottom of the fixed grinding disc 503 and the top inner wall of the slide groove 509. As a result, the fixed grinding disc 503 and the movable grinding disc 502 vibrate due to the collision, and the corn crumbs blocked in the top kneading groove and the bottom kneading groove are shaken off. The bottom of the slider 5010 contacts the top of the top block 508, and the sliding groove 509 is provided to limit the up and down movement of the slider 5010.

The ratchet 606 is provided to limit the clockwise rotation of the ratchet 604 and the kneading roller 602. The ratchet 606 is engaged with the ratchet 604, and when the vertical shaft 501 rotates clockwise, the horizontal shaft 601 is driven to rotate clockwise. At this time, the kneading roller 602 and the ratchet wheel 604 cannot rotate clockwise due to the restriction of the pawl 606.
