[0013] As a further improvement of the technical solution, a cylinder is provided on the side wall of the machine body, a piston rod at the end of the cylinder penetrates the side wall of the machine body and a movable plate is provided at the end, and the volume of feed poured into the machine body is not higher than the set height of the movable plate.

[0014] As a further improvement of the technical solution, a rubber ball is provided at the end of the movable plate, and the rubber ball is driven to move horizontally by controlling the length of the piston rod to block and collide with the rotating stirring rod, causing the surface of the stirring rod to vibrate.

[0015] As a further improvement of the present technical solution, the scraping assembly includes a servo motor arranged on the side wall of the machine body, the output shaft at the end of the servo motor is provided with a screw rod, and a scraper is provided on the surface of the screw rod. The scraper is driven to move horizontally back and forth by the rotation of the screw rod, and the bottom of the scraper is in contact with the side wall of the machine body.

[0016] As a further improvement of the technical solution, the collecting holes are arranged on the upper part of the side wall of the collecting box, and the collecting holes are arranged in a row.

[0017] A second object of the present invention is to provide a method for mixing feed for pig farming, comprising the feed mixing device for pig farming described in any one of the above, comprising the following steps:

[0018] S1. Pour different grains into the machine body through the feed inlet, add water to the grains in the machine body, stir the feed and the water through a stirring rod to form a mixture, the stirring rod drives the main gear to rotate coaxially, and when the main gear rotates, it drives the dust collection component provided on the top to blow air to the outside of the machine body, so that airflow is formed inside the collection box, and the feed powder floating inside the machine body is collected into the collection box. When the feed powder collected in the collection box reaches a set weight, the feed powder applies pressure to the discharge component to automatically open it, and the feed powder falls into the collection box, so that the feed powder and the mixture continue to be stirred;

[0019] S2. During the stirring rod rotating and stirring, the scraping assembly scrapes the side wall of the machine body to make the feed adhering to the side wall of the machine body fall off, so that the feed is stirred evenly;

[0020] S3. When the feed mixing is completed, the feed is discharged through the electromagnetic valve port at the bottom of the machine body. When the discharge is completed, the piston rod at the end of the cylinder drives the movable plate to rotate, so that the rubber ball at the end of the movable plate collides with the stirring blade of the stirring rod, so that the stirring blade on the surface of the stirring rod is impacted and vibrates, and the feed attached to the surface of the stirring blade is shaken off.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. When the feed mixing device for pig breeding mixes grains, the main gear drives the driven gear to rotate, so that the sprocket provided on the top of the rotating rod drives the transmission chain to transmit, and during the rotation of the transmission chain, the fan blades are driven to rotate and blow air to the outside of the machine body. When the fan blades rotate, the air pressure inside the collection box is reduced, so that the air inside the machine body flows into the collection box, and the grain powder floating in the mixing is collected into the collection box, so that the grain powder is prevented from overflowing to the outside of the machine body to cause waste of resources, improve the utilization rate of grain feed, and save feeding costs.

[0023] 2. The feed mixing device for pig breeding has a block disposed under the dust screen. The grain powder sucked into the dust screen by negative pressure hits the surface of the block and falls into the collection box. At the same time, the grain powder collected at the bottom of the collection box is blocked by the block to prevent the grain powder from accumulating on the surface of the dust screen and affecting the adsorption efficiency of the grain powder floating inside the machine body.

[0024] 3. In the feed mixing device for pig breeding, when the weight of the feed powder collected in the collection box reaches the set value, the feed powder squeezes the baffle plate, causing the baffle plate to rotate on the surface of the support rod, thereby creating a gap between the baffle plates, allowing the collected feed powder to fall into the body, forming a mixture with grains and water for uniform mixing, thereby facilitating automatic cleaning of the feed powder and improving the adsorption efficiency of the floating feed powder in the body.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] One of the purposes of the present invention is to Figure 1-Figure 8 As shown, a feed mixing device for pig breeding is provided, comprising a body 100 and a discharge port arranged at the bottom of the body 100, a symmetrical feed port is arranged at the top of the body 100, a stirring rod 101 is arranged inside the body 100, the stirring rod 101 is used to stir and mix the pig feed, a main gear 102 is arranged at the center of the stirring rod 101, a collecting box 200 is arranged on the inner wall of the body 100, a discharge assembly 400 is arranged at the bottom of the collecting box 200, a collecting hole 201 is arranged on the surface of the collecting box 200, the collecting hole 201 is arranged on the upper part of the side wall of the collecting box 200, and the collecting holes 201 are arranged in a symmetrical manner. The collecting box 200 is arranged in a row, and a slot is provided on the top of the collecting box 200. A dust collecting assembly 300 is provided in the slot. The dust collecting assembly 300 is used to form a negative pressure inside the collecting box 200 when the feed is stirred, so as to collect the flying feed powder into the collecting box 200. When the feed powder reaches a set weight, the feed powder applies pressure to the unloading assembly 400 to automatically open, so that the collected feed powder falls into the body 100 and is stirred again. A scraping assembly 500 is provided at the bottom of the body 100. The scraping assembly 500 is used to scrape the feed adhered to the side wall of the body 100 to mix the feeds.

[0041] When the grains are stirred, the main gear 102 drives the driven gear 302 to rotate, so that the sprocket 305 provided on the top of the rotating rod 301 drives the transmission chain 303 to transmit, and during the rotation of the transmission chain 303, the fan blades 304 are driven to rotate and blow air toward the outside of the body 100. When the fan blades 304 rotate, the air pressure inside the collecting box 200 is reduced, so that the air inside the body 100 flows into the collecting box 200, and the grain powder floating during stirring is collected into the collecting box 200, so as to avoid the grain powder overflowing to the outside of the body 100 to cause waste of resources, improve the utilization rate of grain feed, and save feeding costs.

[0042] In order to improve the nutritional richness of the food intake of pigs, it is necessary to mix different varieties of grain feed with water. Since a lot of grain powder is mixed in the grain feed during its production process, the powder is easy to overflow from the inside of the machine body 100 to the outside during the mixing of the grains, causing food waste. Therefore, the dust collection component 300 includes a rotating rod 301 rotatably arranged on the top of the machine body 100, a driven gear 302 is arranged at the bottom of the rotating rod 301, and a fan blade 304 is rotatably arranged in the slot hole. The driven gear 302 and the main gear 102 are meshed and rotated, and a sprocket 305 is arranged on the top of the rotating rod 301 and the surface of the fan blade 304. The sprockets 305 are connected by a transmission chain. 303 transmission connection, when the grains are stirred, the main gear 102 drives the driven gear 302 to rotate, so that the sprocket 305 provided on the top of the rotating rod 301 drives the transmission chain 303 to transmit, and during the rotation of the transmission chain 303, the fan blades 304 are driven to rotate and blow air to the outside of the body 100. When the fan blades 304 rotate, the air pressure inside the collecting box 200 is reduced, so that the air inside the body 100 flows into the collecting box 200, and the grain powder floating in the stirring is collected into the collecting box 200, so as to avoid the grain powder overflowing to the outside of the body 100 to cause waste of resources, thereby improving the utilization rate of the grain feed and saving feeding costs.

[0043] Considering that when the fan blades 304 rotate, the feed powder is easy to overflow from the top slot of the collecting box 200 and cause environmental pollution. Therefore, a dust-proof net 202 is provided at the top slot of the collecting box 200. The dust-proof net 202 is used to prevent the feed powder from overflowing from the slot. The dust-proof net 202 is provided with a block 203. The block 203 is a trapezoidal shape with an opening at the bottom. The dust-proof net 202 is provided at the slot to block the miscellaneous grain powder and prevent the miscellaneous grain powder from overflowing and polluting the environment. At the same time, the block 203 is provided below the dust-proof net 202. The miscellaneous grain powder sucked into the dust-proof net 202 by negative pressure hits the surface of the block 203 and falls into the collecting box 200. At the same time, the miscellaneous grain powder collected at the bottom of the collecting box 200 is blocked by the block 203 to prevent the miscellaneous grain powder from accumulating on the surface of the dust-proof net 202 and affecting the adsorption efficiency of the miscellaneous grain powder floating inside the machine body 100.

[0044] When the feed powder collected in the collecting box 200 reaches a set amount, it needs to be cleaned in time to prevent the feed powder from overflowing from the collecting hole 201 and affecting the adsorption efficiency of the feed powder floating in the body 100. Therefore, the unloading component 400 includes support rods 401 arranged on both sides of the bottom of the collecting box 200, and a baffle 402 is rotatably provided on the surface of the support rod 401. An elastic member 403 is provided on the surface of the support rod 401, and the two ends of the elastic member 403 are respectively connected to the baffle 402 and the inner wall of the support rod 401. When the weight of the feed powder collected in the collecting box 200 reaches a set value, the feed powder squeezes the baffle 402, causing the baffle 402 to rotate on the surface of the support rod 401, thereby generating a gap between the baffles 402, so that the collected feed powder falls into the body 100, forms a mixture with miscellaneous grains and water, and is evenly stirred, thereby facilitating automatic cleaning of the feed powder and improving the adsorption efficiency of the floating feed powder in the body 100.

[0045] During the mixing process of feed, when there are too much feed and water, it is easy to cause uneven mixing of grain feed, resulting in unbalanced nutrition of pigs. Therefore, a cylinder 103 is provided on the side wall of the body 100, and a piston rod at the end of the cylinder 103 penetrates the side wall of the body 100 and a movable plate 104 is provided at the end. The volume of feed poured into the body 100 is not higher than the set height of the movable plate 104. When adding feed and water into the body 100, by observing the height between the feed and the water in the internal volume of the body 100, when the feed and the water are close to the movable plate 104, stop adding feed, thereby ensuring that different grain feeds are mixed evenly during the mixing process and ensuring balanced nutrition for pigs.

[0046] When the feed is stirred, the electromagnetic device at the bottom of the machine body 100 is controlled to open, so that the evenly stirred feed falls into the feed trough below the machine body 100. Since the grain feed and water have a certain degree of adhesion when mixed, a certain amount of feed adheres to the surface of the stirring rod 101, resulting in feed waste. Therefore, a rubber ball 105 is provided at the end of the movable plate 104. The rubber ball 105 is driven to move horizontally by controlling the length of the piston rod to block and collide with the rotating stirring rod 101, so that the surface of the stirring rod 101 vibrates. When the stirring is completed, the movable plate 104 is driven to move horizontally by controlling the piston rod at the end of the cylinder 103. The rubber ball 105 at the end of the movable plate 104 is close to the stirring rod 101. The number of rubber balls 105 corresponds to the stirring blades set on the surface of the stirring rod 101, so that the rotating stirring rod 101 hits and collides with the rubber ball 105. During the collision, the stirring blades on the surface of the stirring rod 101 vibrate, so that the feed adhered to the surface of the stirring blades falls off, avoiding feed waste.

[0047] Considering that during the mixing process of feed, the feed and water are mixed to form a mixture, which is easy to adhere to the inner wall of the body 100, affecting the mixing effect of the feed, therefore, the scraper assembly 500 includes a servo motor 501 arranged on the side wall of the body 100, and the output shaft at the end of the servo motor 501 is provided with a screw rod 502, and the surface of the screw rod 502 is provided with a scraper 503, and the scraper 503 is driven to reciprocate horizontally by the rotation of the screw rod 502, and the bottom of the scraper 503 is in contact with the side wall of the body 100. In the process of mixing the feed, the output shaft at the end of the servo motor 501 drives the screw rod 502 to rotate, so that the scraper 503 provided on the surface of the screw rod 502 moves back and forth horizontally, and the side wall of the body 100 is scraped during the horizontal movement of the scraper 503, thereby improving the mixing effect of the feed.

[0048] When used specifically, different kinds of grain feed are poured into the machine body 100, and water is injected into the machine body 100 at the same time, and the grain feed and the water are stirred and mixed by the stirring rod 101. During the stirring process, the powder in the grains is beaten and floated by the stirring blades of the stirring rod 101. When the stirring rod 101 drives the main gear 102 to rotate to stir the grains, the main gear 102 drives the driven gear 302 to mesh and rotate, so that the sprocket 305 provided on the top of the rotating rod 301 drives the transmission chain 303 to transmit. During the rotation, the fan blades 304 are driven to rotate and blow air to the outside of the machine body 100. When the fan blades 304 rotate, the air pressure inside the collection box 200 is reduced, so that the air inside the machine body 100 flows into the collection box 200, and the floating grain powder during stirring is collected into the collection box 200, so as to avoid the grain powder overflowing to the outside of the machine body 100 to cause waste of resources and save feeding costs. By setting a block 203 under the dust screen 202, the grain powder sucked into the dust screen 202 by negative pressure hits the surface of the block 203 and falls into the collection box 200, and at the same time, the grain powder collected at the bottom of the collecting box 200 is blocked by the block 203 to prevent the grain powder from accumulating on the surface of the dust-proof net 202, thereby improving the adsorption efficiency of the grain powder floating inside the machine body 100. During the mixing process of the feed, the output shaft at the end of the servo motor 501 drives the screw rod 502 to rotate, so that the scraper 503 provided on the surface of the screw rod 502 moves horizontally back and forth. Since the scraper 503 is in contact with the side wall of the machine body 100, the side wall of the machine body 100 is scraped during the horizontal movement of the scraper 503. Thereby, the mixing effect of the feed is improved. When the mixing is completed, the piston rod at the end of the cylinder 103 is controlled to drive the movable plate 104 to move in the horizontal direction, and the rubber ball 105 at the end of the movable plate 104 is close to the stirring rod 101. The number of rubber balls 105 corresponds to the stirring blades arranged on the surface of the stirring rod 101, so that the rotating stirring rod 101 hits and collides with the rubber balls 105. During the collision, the stirring blades on the surface of the stirring rod 101 vibrate, so that the feed adhering to the surface of the stirring blades falls off, thereby avoiding feed waste.

[0049] The second object of the present invention is to provide a method for mixing feed for pig farming, comprising any one of the above-mentioned feed mixing devices for pig farming, comprising the following steps:

[0050] S1. Pour different grains into the machine body 100 through the feed inlet, add water to the grains in the machine body 100, stir the feed and the water through the stirring rod 101 to form a mixture, and the stirring rod 101 drives the main gear 102 to rotate coaxially. When the main gear 102 rotates, it drives the dust collection component 300 provided on the upper part to blow air to the outside of the machine body 100, so that airflow is formed inside the collection box 200, and the feed powder floating in the machine body 100 is collected into the collection box 200. When the feed powder collected in the collection box 200 reaches a set weight, the feed powder applies pressure to the discharge component 400 to automatically open it, and the feed powder falls into the collection box 200, so that the feed powder and the mixture continue to be stirred;

[0051] S2. During the stirring process of the stirring rod 101, the scraping assembly 500 is used to scrape the side wall of the machine body 100, so that the feed adhering to the side wall of the machine body 100 falls off, so that the feed is stirred evenly;

[0052] S3. When the feed mixing is completed, the feed is discharged through the electromagnetic valve port provided at the bottom of the body 100. When the discharge is completed, the piston rod at the end of the cylinder 103 drives the movable plate 104 to rotate, so that the rubber ball 105 provided at the end of the movable plate 104 collides with the stirring blade of the stirring rod 101, so that the stirring blade on the surface of the stirring rod 101 is impacted and vibrates, and the feed attached to the surface of the stirring blade is shaken off.

[0053] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.

Pour different grains into the machine body (100) through the feed inlet, add water to the grains in the machine body (100), stir the feed and the water through the stirring rod (101) to form a mixture, the stirring rod (101) drives the main gear (102) to rotate coaxially, and when the main gear (102) rotates, it drives the dust collection component (300) provided above to blow air to the outside of the machine body (100), so that airflow is formed inside the collection box (200), and feed powder floating inside the machine body (100) is collected into the collection box (200). When the feed powder collected in the collection box (200) reaches a set weight, the feed powder applies pressure to the discharge component (400) to automatically open it, and the feed powder falls into the collection box (200), so that the feed powder and the mixture continue to be stirred; S2. During the process of the stirring rod (101) rotating and stirring, the scraping assembly (500) scrapes the side wall of the machine body (100) to make the feed adhering to the side wall of the machine body (100) fall off, so that the feed is stirred evenly; S3. When the feed is mixed, the feed is discharged through the electromagnetic valve port provided at the bottom of the machine body (100). When the feed is discharged, the piston rod at the end of the cylinder (103) drives the movable plate (104) to rotate, so that the rubber ball (105) provided at the end of the movable plate (104) collides with the stirring blade of the stirring rod (101), so that the stirring blade on the surface of the stirring rod (101) is impacted and vibrates, thereby shaking off the feed attached to the surface of the stirring blade.
