AI Technical Summary
In existing vegetable seed sorting machines, it is difficult to control the feeding speed during the feeding process, which leads to a decline in screening quality.
The loss-in-weight screw feeder is combined with lifting and moving components. The weight of the hopper is detected in real time by a weighing sensor to control the feeding speed. When necessary, the height of the loss-in-weight screw feeder can be lowered to facilitate material replenishment.
It achieves precise control over the feeding speed, improving the screening quality and ease of refilling of the seed sorting machine.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] This embodiment is a vegetable seed selection device.
[0025] like Figures 1-4 As shown, the machine includes a seed sorting machine 1. The seed sorting machine 1 has a feed inlet 2 at the rear end of its upper outer surface. A loss-in-weight screw conveyor 3 is provided on one side of the seed sorting machine 1. The discharge port of the loss-in-weight screw conveyor 3 is located above the feed inlet 2. A lifting assembly 4 is fixedly installed at the lower end of the loss-in-weight screw conveyor 3. A moving assembly 5 is installed at the bottom of the lifting assembly 4. The lifting assembly 4 includes a top plate 6, a fixed plate 7, a movable base 8, a first hydraulic rod 9, a support column 10, a guide ring 11, a guide rod 12, and a slide 17. The moving assembly 5 includes a fixed base 13, a fixed frame 14, a second hydraulic rod 15, and a guide rail 16. The upper outer surface of the top plate 6 is fixedly connected to the lower outer surface of the weighing platform in the loss-in-weight screw conveyor 3.
[0026] There are four sets of support columns 10, which are fixedly installed between the four corners of the upper outer surface of the movable base 8 and the four corners of the lower outer surface of the fixed plate 7. The first hydraulic rod 9 is fixedly installed between the middle of the upper outer surface of the movable base 8 and the middle of the fixed plate 7, and the upper outer surface of the piston rod of the first hydraulic rod 9 is fixedly connected to the middle of the lower outer surface of the top plate 6. There are also four sets of guide rings 11 and four sets of guide rods 12, which are fixedly installed at the four corners of the lower outer surface of the top plate 6, and four sets of guide rings 11 are fixedly installed at the four corners of the upper outer surface of the fixed plate 7. The guide rod 12 passes through the guide ring 11, and the outer wall of the guide rod 12 is slidably connected to the guide ring 11. The slide groove 17 is opened in the middle of the lower outer surface of the movable base 8, and the fixed base 13 is fixedly installed in the middle of the upper outer surface of the fixed base 13. The movable base 8 is slidably connected to the outer wall of the guide rail 16 through the slide groove 17. The fixed frame 14 is fixedly installed in the middle of the rear outer surface of the fixed base 13, and the second hydraulic rod 15 is fixedly installed on the fixed frame 14. The outer surface of one end of the piston rod in the second hydraulic rod 15 is fixedly connected to the middle of the upper part of the rear outer surface of the movable base 8.
[0027] It should be noted that this utility model is a vegetable seed selection device. The seed selection machine 1 and the feed inlet 2 described herein are both existing technologies and can be readily understood by those skilled in the art; therefore, further details are omitted. The device includes a loss-in-weight screw conveyor 3, a lifting assembly 4, and a moving assembly 5. The loss-in-weight screw conveyor 3 primarily uses a weighing sensor to detect the weight of the material in the hopper in real time and controls the material feeding speed based on weight changes. By controlling the feeding speed, the quality of material selection by the seed selection machine 1 is improved. (See attached manual.) Figure 1 As shown, when it is necessary to replenish the loss-in-weight screw conveyor 3, the second hydraulic rod 15 is operated to drive the movable base 8 to move backward. The movable base 8 slides along the outer wall of the guide rail 16 through the slide groove 17, thereby driving the loss-in-weight screw conveyor 3 to move backward and causing the discharge pipe of the loss-in-weight screw conveyor 3 to move away from the upper part of the feed port 2. Then, the first hydraulic rod 9 is operated to drive the top plate 6 to descend. The top plate 6 drives the guide rod 12 to slide along the guide ring 11. After the first hydraulic rod 9 drives the top plate 6 to descend, the top plate 6 drives the loss-in-weight screw conveyor 3 to descend, reducing the height of the loss-in-weight screw conveyor 3, making it easier to replenish the loss-in-weight screw conveyor 3 and improving the convenience of feeding.
