The rotating inclined plate is connected between the two rotating arms. A baffle is provided on the inner front wall of the feed hopper. The top front side of the rotating inclined plate abuts against the bottom of the baffle.
[0007] Furthermore, it also includes fixed blocks, sliding rods, and elastic elements. Fixed blocks are symmetrically arranged on both sides of the stirring blade on the stirring paddle. Sliding rods are symmetrically arranged on both sides of the end of the sliding plate near the rotation axis. The sliding rods pass through two fixed blocks on the same side, and the fixed blocks are slidably connected to the sliding rods on them. Elastic elements are sleeved on the sliding rods.

[0009] Furthermore, the fixed inclined plate is formed by connecting the rear inclined plate and the front cylindrical sleeve. The rear inclined plate is fixedly connected to the inner wall of the feed hopper. The two rotating arms are respectively sleeved on the left and right ends of the front cylindrical sleeve. The total mass of the two rotating arms is twice the mass of the rotating inclined plate.
[0010] Furthermore, it also includes a discharge hopper, a control motor, and a cross plate. The discharge hopper is connected to the bottom left side of the mixing box, and the cross plate is rotatably connected inside the discharge hopper.

Detailed Implementation
[0026] The present invention will now be described in detail with reference to the accompanying drawings.
[0027] A feed mixing device, as shown in Figures 1-5, includes a mixing tank 1, a connecting plate 102, a rotary motor 2, a rotating shaft 201, a belt pulley transmission component 202, a stirring paddle 203, a sliding plate 2031, a reciprocating screw 3, a threaded seat 301, a scraper 302, and a protrusion 303. The right end of the mixing tank 1 is connected to the connecting plate 102, and the top of the connecting plate 102 is equipped with the rotary motor 2. The rotating shaft 201 is rotatably connected to the center of the mixing tank 1, and the stirring paddles 203 are arranged at intervals from left to right on the rotating shaft 201. The mixing paddle 203 is used to mix the feed ingredients in the mixing tank 1. Each mixing paddle 203 has four mixing blades, and the end of each mixing blade away from the rotating shaft 201 is slidably connected to a sliding plate 2031. The right end of the rotating shaft 201 is connected to the output shaft of the rotary motor 2, which provides power to drive the rotating shaft 201 to rotate and achieve the mixing function. A reciprocating screw 3 is rotatably connected to the rear side of the mixing tank 1. A threaded seat 301 is threadedly connected to the reciprocating screw 3, and a scraper is fixedly connected to the threaded seat 301. Scraper 302 slides along the inner wall of mixing tank 1. A pulley transmission component 202 connects the right side of reciprocating screw 3 to the rotating shaft 201, transmitting power. Protrusions 303 are spaced from front to back on the top of the lower part of scraper 302. Slide plate 2031 can contact the protrusions 303. The front side of protrusion 303 is a vertical section, and the top side of protrusion 303 is an arc-shaped slope. The upper side of the vertical section is connected to the front side of the arc-shaped slope, allowing slide plate 2031 to slide along the arc-shaped slope. The sliding plate 2031 has a through hole inside, and the stirring blade of the stirring paddle 203 slides in the through hole. During the stirring process, the sliding plate 2031 will slide and vibrate due to contact with the protrusion 303, preventing feed raw materials from adhering to the stirring paddle 203 and the sliding plate 2031. The scraper 302 is composed of a horizontal base plate and two curved vertical plates connected together. Both the horizontal base plate and the vertical plates are attached to the inner wall of the mixing box 1. The sliding plate 2031 can contact the top of the horizontal base plate, and the protrusion 303 is set at the top of the horizontal base plate.
[0028] As shown in Figures 1 and 6, the mixture also includes a feed hopper 103, a fixed inclined plate 1031, a rotating inclined plate 1032, a rotating arm 1033, and a baffle 104. The feed hopper 103 is connected to the middle of the top of the mixing box 1. The feed hopper 103 is used to add feed ingredients into the mixing box 1. The fixed inclined plate 1031 is fixedly connected to the rear side of the inside of the feed hopper 103. The rotating arms 1033 are symmetrically arranged on the left and right sides of the front of the fixed inclined plate 1031 and are rotatably connected. The rotating inclined plate 1032 is connected between the two rotating arms 1033. A baffle 104 is provided on the inner front wall of the feed hopper 103. The front side of the top of the rotating inclined plate 1032 abuts against the baffle. At the bottom of plate 104, baffle 104 is used to limit the swing range of rotating inclined plate 1032 and prevent it from overturning. Referring to Figure 6, baffle 104 has an inclined surface at the top, which facilitates the falling of feed raw materials and prevents feed raw materials from accumulating on baffle 104. Fixed inclined plate 1031 is formed by connecting rear inclined plate and front cylindrical sleeve. Rear inclined plate is fixedly connected to the inner wall of feed hopper 103. Two rotating arms 1033 are respectively sleeved on the left and right ends of front cylindrical sleeve. Fixed inclined plate 1031 is used to support two rotating arms 1033. The total mass of the two rotating arms 1033 is twice the mass of rotating inclined plate 1032.
[0029] As shown in Figure 5, the system also includes a fixing block 2033, a sliding rod 2034, and an elastic element 2032. Fixing blocks 2033 are symmetrically arranged on both sides of the stirring blade on the stirring paddle 203. Sliding rods 2034 are symmetrically arranged on both sides of the end of the sliding plate 2031 near the rotating shaft 201. The sliding rods 2034 pass through the two fixing blocks 2033 on the same side, and the fixing blocks 2033 are slidably connected to the sliding rods 2034 on them. An elastic element 2032 is sleeved on each sliding rod 2034. One end of the elastic element 2032 is connected to the fixing block 2033 near the rotating shaft 201, and the other end of the elastic element 2032 is connected to the sliding rod 2034.
[0030] As shown in Figures 3, 6, and 8, the mixture also includes a base 101, an elastic membrane 1034, and a guide rod 4. The bottom end of the mixing box 1 is connected to the base 101. An elastic membrane 1034 is connected between the rear end of the rotating inclined plate 1032 and the cylindrical sleeve of the fixed inclined plate 1031. During the movement of the rotating inclined plate 1032, the elastic membrane 1034 will change with the movement of the rotating inclined plate 1032. During the downward rotation of the rotating inclined plate 1032, the elastic membrane 1034 will gradually stretch. During the upward reset of the rotating inclined plate 1032, the elastic membrane 1034 will contract and return to its initial state. A guide rod 4 is connected to the upper side of the inner front wall of the mixing box 1. The guide rod 4 is slidably connected to the upper front side of the scraper 302.
[0031] As shown in Figures 1, 7, and 8, the mixing box 1 also includes a discharge hopper 5, a control motor 501, a cross plate 502, and inclined blocks 503. The discharge hopper 5 is connected to the bottom left side of the mixing box 1. The cross plate 502 is rotatably connected inside the discharge hopper 5. The control motor 501 is connected to the front end of the discharge hopper 5. The output shaft of the control motor 501 passes through the discharge hopper 5 and connects to the front end of the cross plate 502. Inclined blocks 503 are connected to the inner left and right walls of the discharge hopper 5. The top of each inclined block 503 has an inclined surface. After mixing is complete, the control motor 501 is started, and the control motor 501 drives... The rotating cross plate 502 agitates the feed material in the discharge hopper 5 during the rotation process, causing the feed material to fall continuously from the bottom of the discharge hopper 5. At this time, as the scraper 302 moves to the left, the scraper 302 continuously pushes the feed material in the mixing box 1 to the left side of the mixing box 1, which is conducive to the feed material coming out of the mixing box 1. During the discharge process, the inclined surface on the inclined block 503 helps to guide the feed material to fall onto the cross plate 502, so that the feed material flows out smoothly and can effectively prevent the feed material from remaining in the discharge hopper 5.
[0032] When using this feed mixing device, the feed ingredients and additives to be mixed are first added to the mixing box 1 through the feed hopper 103. The feed and additives fall directly onto the rotating inclined plate 1032. Initially, since the total mass of the two rotating arms 1033 is greater than the mass of the rotating inclined plate 1032, the rotating inclined plate 1032 abuts against the baffle 104, and there is no gap between the rotating inclined plate 1032 and the feed hopper 103. As the feed ingredients gradually accumulate on the rotating inclined plate 1032, the rotating inclined plate 1032 will gradually rotate downward with the connection point with the rotating arm 1033 as the center of rotation, while the rotating arm 1033 will gradually tilt upward with the connection point as the center of rotation. As the feed ingredients on the rotating inclined plate 1032 continue to increase, the rotating inclined plate 1032... As the mass on one side of 032 increases, the rotating inclined plate 1032 will continue to rotate downwards. Eventually, a gap will appear between the rotating inclined plate 1032 and the feed hopper 103. Under the action of gravity, the feed material will fall from the rotating inclined plate 1032 into the mixing box 1. At this time, the total mass of the two rotating arms 1033 will again be greater than the mass of the rotating inclined plate 1032. Under the downward pressure of the two rotating arms 1033, the rotating inclined plate 1032 will return to its initial position, and the top of the rotating inclined plate 1032 will again contact the baffle 104. During the process of adding the feed material to be mixed into the mixing box 1, the movement state of the rotating inclined plate 1032 will repeat the above process. After the feed material to be mixed is added into the mixing box 1, the rotating inclined plate 1032 will contact the baffle 104. This creates a sealed space within the mixing chamber 1, which facilitates the mixing of feed ingredients. Simultaneously, the rotary motor 2 is activated, driving the rotary shaft 201 to rotate. The four agitator blades on the stirring paddle 203 follow the rotation of the shaft 201, thoroughly mixing the feed ingredients. The rotary shaft 201 transmits power to the reciprocating screw 3 via the pulley transmission component 202, causing the screw 3 to rotate. This drives the threaded seat 301, which is threaded to it, to move the scraper 302 back and forth along the inner wall of the mixing chamber 1. The scraper 302 continuously scrapes off the feed ingredients adhering to the inner wall of the chamber, enhancing the mixing effect of the stirring paddle 203. During the left-right movement of the scraper 302, the protrusions 303 on the scraper 302 may interact with the lower sliding plate 2031. Initially, the lower sliding plate 2031 contacts the arc-shaped inclined surface at the top of the protrusion 303 (refer to Figure 3, the rotation direction of the rotating shaft 201 is clockwise). The arc-shaped inclined surface at the top of the protrusion 303 will push the sliding plate 2031 to slide upward along the stirring blade (the sliding plate 2031 slides upward under the squeezing force and moves relative to the stirring blade through the through hole). During this process, the sliding rod 2034 follows the sliding plate 2031 to slide upward along the fixed block 2033. The elastic element 2032 changes from the initial state to the compressed state. As the sliding plate 2031 rotates, when the sliding plate 2031 is no longer in contact with the arc-shaped inclined surface at the top of the protrusion 303, the protrusion 303 will no longer squeeze the sliding plate 2031, and the elastic element 2032 will return to its original position. Under the action of the elastic element 2032...The slide bar 2034 and the connected slide plate 2031 will return to their initial positions. During this process, the slide plate 2031 will directly impact the scraper 302, generating vibration and causing the feed material adhering to the slide plate 2031 and the mixing blades to fall off (this helps improve the overall uniformity of the feed material mixing in the mixing tank 1).
[0033] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
