[0005] The purpose of this invention is to provide an automated seed weighing device with high weighing accuracy.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an automated seed weighing device, comprising a base, a weighing box fixedly connected to the top of the base, a fixed seat fixedly connected to the inner wall of the weighing box, a vibration spring fixedly connected to the top of the fixed seat, a spring connecting seat fixedly connected to the top of the vibration spring, a vibrating screen plate fixedly connected to the top of the spring connecting seat, a material discharge hole opened on the upper surface of the vibrating screen plate, a motor connecting seat fixedly connected to the lower surface of the vibrating screen plate, a vibration motor fixedly connected to the bottom of the motor connecting seat, a fixing groove opened on the upper surface of the weighing box, a dust collection hood fixedly connected to the inner wall of the fixing groove, a dust collection pipe fixedly connected to the top of the dust collection hood, a dust collection box fixedly connected to one end of the dust collection pipe, and an air suction pump fixedly connected to one side of the dust collection box.

When the vibration motor is working, it drives the vibrating screen plate to vibrate at high speed, which in turn drives the seeds above the vibrating screen plate to vibrate rapidly, separating the impurities and dust mixed in the seeds. The separated seeds reach the weighing device below through the feeding hole, while the impurities remaining above the vibrating screen plate reach the impurity collection box through the impurity outlet. The mixed dust is sucked into the dust collection box with the cooperation of the dust collection hood, dust collection pipe, dust collection box, and suction pump. This design realizes the automatic impurity removal function before the seed weighing operation, which can effectively avoid the impurities in the seeds from affecting the accuracy of the weighing results, thereby achieving the effect of high weighing accuracy of the device.

[0008] A further feature of this invention is that a hopper support is fixedly connected to the upper surface of the base, and a discharge hopper is fixedly connected to the inner wall of the hopper support.

[0009] By adopting the above technical solution and setting up a hopper support, the hopper can be supported and fixed.

[0010] A further feature of this invention is that the top of the discharge bin is hinged with a bin cover, and the top of the bin cover is fixedly connected with a handle.

[0011] By adopting the above technical solution and setting a cover, the feeding bin is sealed to prevent foreign objects from entering the feeding bin when seeds are not being filled.

[0012] A further feature of this invention is that a screw feeder is fixedly connected to the bottom of the feeding hopper, the screw feeder is fixedly connected to the weighing box, the screw feeder includes a drive motor, and the output end of the drive motor is fixedly connected to a screw feeding blade.

[0013] By adopting the above technical solution and setting up a screw feeder, the seeds in the feeding hopper can be automatically transported to the inside of the weighing box.

[0014] A further feature of this invention is that an impurity collection box is fixedly connected to one side of the weighing box, and an impurity outlet is provided on one side of the weighing box, with the impurity outlet located above the impurity collection box.

[0016] A further feature of this invention is that a mounting base is fixedly connected to the inner bottom wall of the dust collection box, and a filter screen is fixedly connected to the top of the mounting base.

[0017] By adopting the above technical solution and setting up a filter screen, dust can be blocked and filtered, preventing dust from entering the air pump.

[0018] A further feature of this invention is that a seed collection seat is fixedly connected to the bottom wall of the weighing box, a collection cavity is formed on the upper surface of the seed collection seat, a weighing device is fixedly installed on the bottom wall of the collection cavity, and a display is provided on the outer surface of the weighing box, and the display is electrically connected to the weighing device.

[0019] By adopting the above technical solution and setting up a seed collection seat, the seeds that have passed through the vibrating screen can be collected, which facilitates subsequent weighing operations.

[0020] A further feature of this invention is that: a feeding channel is provided inside the seed collection seat, a first cylinder is fixedly connected to the inner wall of the weighing box, a sealing plate is fixedly connected to the output end of the first cylinder, and the first cylinder is located inside the feeding channel.

[0021] By adopting the above technical solution and setting a sealing plate, the collection chamber is sealed to prevent the seeds from falling into the feeding channel before the weighing is completed.

[0022] A further feature of this invention is that a driving cavity is provided inside the seed collecting seat, and a second cylinder is fixedly connected to the inner wall of the driving cavity, and a pusher plate is fixedly connected to the output end of the second cylinder.

[0023] By adopting the above technical solution, and by setting up a feeding channel, a first cylinder, a sealing plate, a driving chamber, a second cylinder, and a pusher plate, after the seeds are weighed, the first and second cylinders work simultaneously. The first cylinder drives the sealing plate to move to the right, at which point the sealing plate loosens its blockage of the feeding channel. When the second cylinder works, it drives the pusher plate to move to the right, which can push the seeds above the weighing device into the feeding channel, allowing them to be discharged from the weighing box through the discharge hole. This design not only achieves the automatic discharge of seeds after weighing, but also allows the pusher plate to push out all the seeds remaining above the weighing device, preventing seeds from remaining above the weighing device and affecting the weighing results of subsequent seeds, thereby enhancing the practicality of the device.

[0024] A further feature of this invention is that a discharge hole is provided on one side of the weighing box, and the discharge hole is connected to the material feeding channel.

[0025] By adopting the above technical solution and setting a discharge hole, it is convenient to discharge the seeds inside the feeding channel to the outside of the weighing box.

The vibration motor drives the vibrating screen plate to vibrate at high speed, which in turn causes the seeds above the screen plate to vibrate rapidly, separating impurities and dust from the seeds. The separated seeds reach the weighing device below through the feeding hole, while the impurities remaining above the vibrating screen plate reach the impurity collection box through the impurity outlet. The dust, with the cooperation of the dust collection hood, dust collection pipe, dust collection box, and air suction pump, is sucked into the dust collection box. This design achieves automatic removal of impurities before the seed weighing operation. The device features a complex structure that effectively prevents impurities in the seeds from affecting the accuracy of the weighing results, thus achieving high weighing precision. By incorporating a feeding channel, a first cylinder, a sealing plate, a drive chamber, a second cylinder, and a pusher plate, the first and second cylinders operate simultaneously after the seeds are weighed. The first cylinder moves the sealing plate to the right, releasing it from the feeding channel. Simultaneously, the second cylinder moves the pusher plate to the right, pushing the seeds above the weighing device into the feeding channel and allowing them to exit the weighing box through the discharge hole. This design not only achieves automatic seed discharge after weighing but also ensures that the pusher plate removes any seeds remaining above the weighing device, preventing them from affecting subsequent weighing results and enhancing the device's practicality.
