[0025] Reference Figure 1-Figure 3 , which is an embodiment of the present utility model, provides an intelligent dosing hopper, including a main unit 100 and a discharge unit 200.

[0026] The main unit 100 includes a bracket 101 and a hopper body 102 mounted to match the bracket 101. A discharge port 104 is provided at the bottom of the hopper body 102. The medicine in the hopper body 102 is discharged downward through the discharge port 104.

[0027] The unloading unit 200 includes a motor 201 fixedly mounted on the lower end of the hopper body 102, the output end of the motor 201 is fixedly connected to the first bevel gear 204, the bottom end of the bracket 101 is symmetrically mounted with a bearing seat 208, and the opposite surfaces of the two sets of bearing seats 208 are rotatably connected to a transmission shaft 206, the outer surface of the transmission shaft 206 is fixedly connected to a second bevel gear 205, and the second bevel gear 205 is meshed with the first bevel gear 204, and the two ends of the transmission shaft 206 are fixedly connected to a transmission gear 207, the bottom end of the hopper body 102 is symmetrically provided with a tooth plate 209, and the tooth plate 209 and the transmission gear 207 is engaged, the bottom ends of the two groups of tooth plates 209 are fixedly connected with a sealing plate 212, the bottom end of the hopper body 102 is provided with a slide rail 211, and the slide rail 211 and the sealing plate 212 are slidably connected, the bottom end of the inner cavity of the slide rail 211 is installed with a limit switch 213, and the top of the limit switch 213 is in contact with the bottom end of the sealing plate 212, the bottom end of the hopper body 102 is provided with a guide structure, and the top end of the hopper body 102 is provided with a monitoring structure. The motor 201 drives the first bevel gear 204 to rotate, and the first bevel gear 204 drives the second bevel gear 205 to rotate. Then, the second bevel gear 205 is rotated. The rotation drives the rotation of the transmission shaft 206, and the transmission shaft 206 further drives the transmission gears 207 installed on both sides thereof to rotate. The transmission gears 207 are meshed with the toothed plate 209 provided at the bottom of the bracket 101. Therefore, when the transmission gears 207 rotate, they push the toothed plate 209 to move linearly. In order to ensure the stability of the toothed plate 209 during movement, a guide structure is also designed. As the toothed plate 209 moves, it drives the sealing plate 212 connected thereto, so that the sealing plate 212 opens or closes the discharge port 104 of the hopper body 102. When the bottom end of the sealing plate 212 is aligned with the guide rail provided When the limit switch 213 of the inner cavity 211 contacts, the motor 201 will automatically stop working. In addition, when the material in the hopper body 102 is completely discharged, the monitoring structure will detect this state and trigger the motor 201 to rotate in the opposite direction, thereby driving the sealing plate 212 to close. Through the forward and reverse control of the motor 201, the first bevel gear 204 can be driven to drive the two sets of transmission gears 207 to rotate forward and reverse, thereby realizing the opening and closing action of the sealing plate 212 and achieving the effect of automatic unloading. This design does not require manual operation and realizes the function of intelligent closing, which not only improves work efficiency but also reduces labor costs.

[0028] The guide structure includes guide grooves 210 symmetrically opened at the bottom end of the hopper body 102. The inner cavities of the two groups of guide grooves 210 are slidably connected with sliders, and the bottom ends of the sliders are fixedly connected to the top ends of the tooth plates 209. During the movement of the tooth plates 209, they pull the sliders to slide smoothly along the internal space of the guide grooves 210, ensuring the smoothness and stability of the tooth plates 209 during movement.

[0029] The monitoring unit includes a horizontal plate 202 installed on the top of the hopper body 102. An ultrasonic level meter 203 is installed on one side of the horizontal plate 202. The distance is calculated by measuring the time of transmitting and receiving sound waves or microwaves based on the principle of echo ranging. This is a prior art and will not be described in detail here.

[0030] An electric control box 214 is installed on one side of the hopper body 102, and the electric control box 214 is electrically connected to the motor 201, the ultrasonic level meter 203, and the limit switch 213 respectively. The electric control box 214 receives signals from the motor 201 and the ultrasonic level meter 203 to control whether the limit switch 213 is working, and the inner cavity of the electric control box 214 is heavy-duty cable connector.

[0031] A forklift cover 103 is symmetrically mounted on the bottom end of the bracket 101, and a rubber pad is provided in the inner cavity of the forklift cover 103. The bracket 101 is provided with 013, which is convenient for forklift transportation.

[0032] The hopper body 102 is an oblique cone structure, and the discharge port 104 is located on the left side of the hopper body 102. The design of the hopper body 102 as an oblique cone is conducive to automatic discharge of materials by gravity as the gate opens.

[0033] During use, the motor 201 drives the first bevel gear 204 to rotate, and the first bevel gear 204 drives the second bevel gear 205 to rotate. Then, the rotation of the second bevel gear 205 drives the rotation of the transmission shaft 206, and the transmission shaft 206 further drives the transmission gear 207 installed on both sides thereof to rotate. The transmission gear 207 is meshed with the tooth plate 209 provided at the bottom of the bracket 101. Therefore, when the transmission gear 207 rotates, it pushes the tooth plate 209 to move linearly. In order to ensure the stability of the tooth plate 209 during movement, a guide structure is also designed. As the tooth plate 209 moves, it drives the sealing plate 212 connected thereto, so that the sealing plate 212 opens or closes the discharge port 104 of the hopper body 102. When the bottom end of the sealing plate 212 contacts the limit switch 213 provided in the inner cavity of the slide rail 211, the limit switch 213 sends a signal to the electric control box 214 to control the motor 201 to stop working. In addition, when the material in the hopper body 102 is completely discharged, the monitoring structure will detect this state and make the motor 201 rotate in the opposite direction, thereby driving the sealing plate 212 to close. Through the forward and reverse control of the motor 201, the first bevel gear 204 can be driven to drive the two sets of transmission gears 207 to rotate forward and reverse, thereby realizing the opening and closing action of the sealing plate 212 and achieving the effect of automatic unloading. This design does not require manual operation and realizes the function of intelligent closing, which not only improves work efficiency but also reduces labor costs.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
