[0003] After checking the publication number: CN215515385U, a circular bottom bucket type powder elevator is disclosed. This technology discloses "a circular bottom bucket type powder elevator, including an elevator base, a lifting pipe, an elevator head, a transmission mechanism, and a driving device; the elevator head is fixedly connected to the elevator base through the lifting pipe, the driving device is fixed to one side of the elevator head, the transmission mechanism includes a transmission roller, a redirecting roller, a conveyor belt, and a plurality of hoppers; the transmission roller is arranged in the elevator base, the redirecting roller is arranged in the elevator head, the transmission roller and the redirecting roller are rotatably connected to each other through a conveyor belt, the plurality of hoppers are fixed to one side of the outer periphery of the conveyor belt, and the bottom of the elevator base is arc-shaped" and other technical solutions, which have "the ability to minimize the material residue at the bottom of the elevator base according to actual conditions, so that the operation is stable and the performance is reliable, and it is mainly suitable for the lifting operation of agricultural grain, feed and granular materials";

[0004] When the bucket elevator is working, the material is not directly added to the bucket when it flows into the machine base. When the bucket continues to move, the material is loaded together. However, due to the accumulation of material in the machine base, the resistance to the movement of the bucket increases, and the material may be squeezed by the bucket and may be broken or deformed. This problem is particularly prominent for fragile or easily deformed materials. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a low-crushing elevator with air screening feeding and quantitative feeding. It has the characteristics of air screening the material, which helps to remove impurities in the material, as well as automatic loading, feeding and unloading, and reducing the crushing of the material during the process.

[0014] Beneficial effects

[0015] The utility model provides a low-crushing elevator with air screen feeding and quantitative feeding. Compared with the existing technology, it has the following advantages:

[0016] (1) When the slide drives the bucket to move downward, the slide pushes the shifting frame downward to flip it, and the shifting frame drives the front end of the movable bucket to extend above the bucket, so that the material inside the movable bucket falls into the bucket, and then the slide drives the bucket to move upward. After moving to the discharge port, due to the lack of an axle seat to limit the bucket, the bucket tilts and flips toward the discharge port by its own gravity, so that the material inside the bucket can be discharged through the discharge port.

[0017] (2) The eccentric disk is driven by the output end of the second motor to cooperate with the connecting rod to drive the screen. The screen is vibrated by the guide rod and the spring to screen the material. At the same time, the fan is connected to the air outlet to take away the light part of the material, which helps to remove impurities in the material and improve the purity of the material and the subsequent processing efficiency.

DETAILED DESCRIPTION

[0024] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-5 The utility model provides a technical solution for a low-crushing elevator with air screen feeding and quantitative feeding: a low-crushing elevator with air screen feeding and quantitative feeding, comprising a base 1, a conveying mechanism 2 provided on the base 1 and used for conveying materials, a wind screening mechanism 3 provided on the base 1 and used for air screening materials, and the conveying mechanism 2 includes:

[0026] The feeding assembly 21 includes an axle seat 211 fixed to the middle of the top of the base 1, a shifting frame 212 hinged to the upper end of the axle seat 211, a movable bucket 213 fixed to the upper end of the shifting frame 212, and a spring plate 214 fixed to the front end of the movable bucket 213;

[0027] The feeding assembly 22 includes a base 221 fixed to the front end of the top of the base 1, pulleys 222 rotatably installed at the upper and lower ends of the base 221, a belt 223 installed between the upper and lower pulleys 222, a slide 224 longitudinally slidably installed inside the base 221, and the slide 224 is fixed to the belt 223, and a bucket 225 is hinged at the upper end of the slide 224.

[0028] In this embodiment, when the slide 224 drives the bucket 225 to move downward, the slide 224 pushes the shifting frame 212 downward to flip it, and the shifting frame 212 drives the front end of the movable bucket 213 to extend above the bucket 225, so that the material inside the movable bucket 213 falls into the bucket 225, and then the slide 224 drives the bucket 225 to move upward. After moving to the discharge port 227, due to the lack of the axle seat 211 to limit the bucket 225, the bucket 225 tilts and flips toward the discharge port 227 by its own gravity, so that the material inside the bucket 225 can be discharged through the discharge port 227.

[0029] Specifically, the wind screening mechanism 3 includes a silo 31 arranged on the feeding assembly 21, a screen 32 arranged inside the silo 31, guide rods 33 fixed at the four corners of the bottom of the screen 32, and the four guide rods 33 are respectively slidably installed with the four corners inside the silo 31, and springs 34 are sleeved and installed on the guide rods 33, eccentric disks 35 are rotatably installed on the inner walls of both ends of the silo 31, a connecting rod 36 is pivotally connected to the outer edge of the eccentric disk 35, and the lower end of the connecting rod 36 is pivotally connected to the screen 32, a second motor 37 is installed on the outer walls of both ends of the silo 31 and is used to drive the eccentric disk 35, a feed port 38 fixed at the upper end of the silo 31, and an air outlet 39 fixed at the rear end of the silo 31.

[0030] In this embodiment, the material is poured into the hopper 31 from the feed port 38, and the eccentric disk 35 is driven by the output end of the second motor 37 to cooperate with the connecting rod 36 to drive the screen 32. The screen 32 vibrates through the guide rod 33 and the spring 34 to screen the material. At the same time, the fan is connected through the air port 39 to take away the light part of the material, which helps to remove impurities in the material and improve the purity of the material and the subsequent processing efficiency.

[0031] Specifically, the feeding assembly 21 further includes a limiting seat 217 fixed to the top of the base 1 , and the limiting seat 217 is located behind the shaft seat 211 .

[0032] In this embodiment, when the slide plate 224 moves upward and disengages from the shifting frame 212 , the rebound pressure of the spring plate 214 pushes the movable bucket 213 backward until the shifting frame 212 contacts the limiting seat 217 , thereby achieving the reset of the movable bucket 213 .

[0033] Specifically, the feeding assembly 21 also includes a frame 218 fixed at the top rear end of the base 1, a hopper 219 fixed at the upper end of the frame 218, a vibrator 2110 installed in the middle of the frame 218, and a trough 2111 installed at the upper end of the vibrator 2110.

[0034] In this embodiment, the material after the air screening enters the hopper 219 and then falls into the inside of the material trough 2111, and the material in the material trough 2111 is sent into the movable hopper 213 through the vertical vibrator 2110.

[0035] Specifically, the feeding assembly 21 further includes a carrier plate 215 installed at the lower end of the movable bucket 213 , a pressure sensor 216 installed at the bottom of the movable bucket 213 , and the pressure sensor 216 is connected to the carrier plate 215 .

[0036] In this embodiment, when the material load inside the movable bucket 213 reaches a preset threshold value of the pressure sensor 216, the vertical vibrator 2110 stops working to prevent the material trough 2111 from continuing to discharge material.

[0037] Specifically, the feeding assembly 22 further includes a first motor 226 mounted on the outer wall of the machine base 221 and used to drive the pulley 222 , and a discharge port 227 fixed on the outer wall of the upper end of the machine base 221 .

[0038] In this embodiment, the output end of the first motor 226 drives the pulley 222 in cooperation with the belt 223 to drive the bucket 225 on the slide 224 to move up and down.

[0039] The working principle and use process of the utility model are as follows: first, the material is poured into the hopper 31 from the feed port 38, and the eccentric disk 35 is driven by the output end of the second motor 37 to cooperate with the connecting rod 36 to drive the screen 32. The screen 32 vibrates through the guide rod 33 and the spring 34, thereby screening the material. At the same time, the fan is connected to the air port 39 to take away the light part of the material, which helps to remove impurities in the material, improve the purity of the material and the efficiency of subsequent processing;

[0040] Then, the material after the air screening enters the hopper 219 and then falls into the trough 2111. The material in the trough 2111 is sent to the movable hopper 213 through the vertical vibrator 2110. When the material load in the movable hopper 213 reaches the threshold value preset by the pressure sensor 216, the vertical vibrator 2110 stops working to prevent the trough 2111 from continuing to discharge material.

[0041] Finally, the output end of the first motor 226 drives the pulley 222 in cooperation with the belt 223 to drive the tipping bucket 225 on the slide 224 to rise and fall. When the slide 224 drives the tipping bucket 225 to move downward, the slide 224 pushes the shifting frame 212 downward to flip over. The shifting frame 212 drives the front end of the movable bucket 213 to extend above the tipping bucket 225, so that the material inside the movable bucket 213 falls into the tipping bucket 225. The slide 224 then drives the tipping bucket 225 to move upward. After moving to the discharge port 227, due to the lack of the shaft seat 211 to limit the tipping bucket 225, the tipping bucket 225 tilts and flips toward the discharge port 227 by its own gravity, so that the material inside the tipping bucket 225 can be discharged through the discharge port 227.

[0042] At the same time, when the slide plate 224 moves upward and disengages from the shifting frame 212 , the rebound pressure of the spring plate 214 pushes the movable bucket 213 to move backward until the shifting frame 212 contacts the limiting seat 217 , thereby achieving the reset of the movable bucket 213 .
