[0027] The material shifting assembly 320 also includes a fixed frame 3219 arranged between the feed frame 200 and the material shifting plate 310, two guide tubes 3225 are fixedly installed on the inner wall of the fixed frame 3219, and the bottom ends of the two guide tubes 3225 are slidably installed with the same movable frame 3220, and a distance sensor 3221 is fixedly installed on the inner wall of the fixed frame 3219, and the distance sensor 3221 is located at the top of the movable frame 3220, and a movable plate 3222 is fixedly installed on the bottom of the movable frame 3220.

[0028] A fixed frame 3211 is fixedly installed on the top of the support frame 321, and a movable plate 3214 is slidably installed inside the fixed frame 3211. A connecting rod 3212 is rotatably installed on the bottom of the movable plate 3214. One end of the connecting rod 3212 penetrates into the interior of the support frame 321 and is slidably connected to the rotating rod 322. An air pump 3215 is fixedly installed on the top of the fixed frame 3211. Two fixed tubes 3217 are fixedly connected to the inner top wall of the fixed frame 3211. The bottom ends of the two fixed tubes 3217 are slidably connected to movable tubes 3218. The bottom ends of the two movable tubes 3218 are fixedly connected to the top of the movable plate 3214. A delivery pipe 3216 is fixedly installed between the air pump 3215 and the two fixed tubes 3217.

[0029] The top end of the rotating rod 322 is located inside the connecting rod 3212 , and a first spring 3213 is fixedly installed between the top end of the rotating rod 322 and the inside of the connecting rod 3212 .

[0030] The second springs 3226 are fixedly connected between the moving frame 3220 and the inside of the two guide tubes 3225 , respectively. A guide plate 3223 is fixedly installed on one side of the moving plate 3222 , and the guide plate 3223 is arranged obliquely.

[0031] A plurality of contact wheels 3224 are fixedly mounted on the bottom of the movable plate 3222 , and the plurality of contact wheels 3224 are equidistantly distributed.

[0032] In this embodiment, the material-pickup plate 310 and the contact plate 324 are both controlled to move up and down by injecting and exhausting air into the two fixed tubes 3217 through the air pump 3215. When in use, the motor 327 drives the reciprocating screw 3210 to rotate, so that the reciprocating screw 3210 drives the driving block 329 to reciprocate in the moving groove 328, and controls the material-pickup plate 310 to reciprocate with the rotating rod 322 as the fulcrum, so that the material-pickup plate 310 continuously drives the contact plate 324 to perform fan-shaped material-pickup. When the contact plate 324 pokes the material, the claw hook 325 helps the contact plate 324 to better grasp or guide larger granular materials when contacting the material, thereby preventing material accumulation and improving material dispersion efficiency. At the same time as the material is input, it will preferentially contact the moving plate 3222. The guide plate 3223 obliquely arranged on one side of the moving plate 3222 can facilitate the material to enter the bottom of the moving plate 3222, and the multiple contact wheels 3224 at the bottom of the moving plate 3222 can reduce the contact friction between the moving plate 3222 and the material. When the moving plate 3222 contacts the material, it synchronously drives the moving frame 3220 to move. At this time, the distance sensor 3221 accurately detects the height of the material accumulation by detecting the moving distance of the moving frame 3220, and controls the air pump 3215 through its built-in controller feedback signal, thereby controlling the position of the material stripping plate 310 and the contact plate 324, thereby improving the effect of uniform material stripping, and at the same time avoiding damage to the material stripping plate 310 caused by excessively high materials directly contacting the lower material stripping plate 310.

[0033] like Figure 2 , Figure 3 and Figure 8 As shown, the unloading assembly 330 includes a movable frame 331 arranged on one side of the feeding frame 200, and a unloading plate 333 is slidably installed inside the movable frame 331. One side of the unloading plate 333 extends to the inside of the feeding frame 200. The unloading plate 333 is inclined, and an electric push rod 332 is fixedly installed on the surface of the movable frame 331. The output end of the electric push rod 332 is fixedly connected to the bottom of the unloading plate 333.

[0034] A buffer plate 334 is fixedly mounted on the surface of the blanking plate 333 , and a plurality of buffer pads 335 equidistantly distributed are fixedly mounted inside the buffer plate 334 . The plurality of buffer pads 335 are all in a semicircular shape.

[0035] The movable frame 331 is slidably connected to the surface of the feed frame 200. Two support rods 336 are fixedly installed at the bottom of the movable frame 331, and the two support rods 336 are slidably connected to the surface of the feed frame 200. A third spring 337 is sleeved through the outer side of the support rod 336, and the other end of the third spring 337 is fixedly connected to the feed frame 200.

[0036] In this embodiment, when the material is poured into the material frame 200, the electric push rod 332 can be used to continuously push the discharge plate 333, so that the discharge plate 333 and the contacting material exert an oblique downward force to reduce the impact force of the material falling directly. When the material is poured from the feed frame 200, the buffer pad 335 can effectively absorb the falling impact force of the material, slow down the collision between the material and the discharge plate 333, and avoid the material from causing excessive impact on the discharge plate 333. The semicircular design of the buffer pad 335 helps to disperse the impact force and enhance the buffering effect. At the same time, when the discharge plate 333 is subjected to impact, the movable frame 331 synchronously drives the support rod 336 to move downward, squeezes the third spring 337, and provides a certain buffering force through its elastic support, thereby further reducing the damage to the discharge plate 333.

[0037] Working principle: when in use, the motor 327 drives the reciprocating screw 3210 to rotate, so that the reciprocating screw 3210 drives the driving block 329 to reciprocate in the moving groove 328, and controls the material-dispensing plate 310 to reciprocate with the rotating rod 322 as the fulcrum, so that the material-dispensing plate 310 continuously drives the contact plate 324 to perform fan-shaped material dispensing. When the contact plate 324 dispenses materials, the claw hook 325 helps the contact plate 324 to better grasp or guide larger particles when contacting the material, prevent material accumulation, and improve material dispersion efficiency. At the same time as the material is input, it will preferentially contact the moving plate 3222. The guide plate 3223 obliquely arranged on one side of the moving plate 3222 can make The material can easily enter the bottom of the moving plate 3222, and the multiple contact wheels 3224 at the bottom of the moving plate 3222 can reduce the contact friction between the moving plate 3222 and the material. When the moving plate 3222 contacts the material, it synchronously drives the moving frame 3220 to move. At this time, the distance sensor 3221 detects the moving distance of the moving frame 3220 to accurately detect the height of the material accumulation, and controls the air pump 3215 through its built-in controller feedback signal, thereby controlling the position of the material stripping plate 310 and the contact plate 324, thereby improving the effect of uniform material stripping, and also avoiding the damage to the material stripping plate 310 caused by the excessively high material directly contacting the lower material stripping plate 310; When the material is poured into the material frame 200, the electric push rod 332 can be used to continuously push the discharge plate 333, so that the discharge plate 333 and the contacting material exert an oblique downward force to reduce the impact force of the material falling directly. When the material is poured from the feed frame 200, the buffer pad 335 can effectively absorb the falling impact force of the material, slow down the collision between the material and the discharge plate 333, and avoid the material from causing excessive impact on the discharge plate 333. The semicircular design of the buffer pad 335 helps to disperse the impact force and enhance the buffering effect. At the same time, when the discharge plate 333 is subjected to impact, the movable frame 331 synchronously drives the support rod 336 to move downward, squeezes the third spring 337, and provides a certain buffering force through its elastic support, thereby further reducing the damage to the discharge plate 333.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
