A crossbar 4 is fixedly installed on the top of the rotating rod 3. A ring 5 is fixedly installed on the left side of the crossbar 4. The ring 5 is located on the upper side of the electronic scale 1. Electronic Scale 1: It adopts a high-precision weighing sensor with a range of 0-5kg and an accuracy of 0.1g. It is made of stainless steel and is used to accurately weigh chestnuts.

[0017] Motor 2: Model is a miniature stepper motor, power is 10W, speed is 0 - 50r / min, material is aluminum alloy, used to drive the rotating rod 3 to rotate to achieve chestnut sorting.

[0018] A miniature stepper motor of model 57BYG250-51 can be selected. This motor is a two-phase stepper motor with a rated power of 10W, a rated speed of 1000rpm, and an external dimension of 575751mm. It can meet the power requirements of the device to drive the rotating rod to achieve chestnut sorting.

[0019] Rotating rod 3: 10mm in diameter, 150mm in length, made of 45# steel, serves as a transmission link between motor 2 and crossbar 4.

[0020] Crossbar 4: 200mm in length, 20mm in width, and 10mm in thickness, made of aluminum alloy, used to install ring 5 and transmit the rotation of rotating rod 3.

[0021] Ring 5: Inner diameter 30mm, outer diameter 40mm, thickness 5mm, made of plastic, used to agitate chestnuts for sorting.

[0022] Traditional chestnut quality testing devices are divided into surface damage, wormhole detection, and weight detection. Most current chestnut weight detection devices involve placing chestnuts on an electronic scale to filter out chestnuts of the same weight range. After weighing the chestnuts on the electronic scale, they still need to be manually picked out and sorted, which is inconvenient to operate and not very practical.

[0023] This solution features a motor-controlled ring at the top of the electronic scale. After the chestnuts are weighed, the motor can rotate forward and backward to sort them to the desired positions, eliminating the need for manual sorting. This makes the operation convenient and improves practicality. Additionally, there are fixing rings on both sides of the electronic scale, with bags that can be installed at the bottom of the fixing rings to receive the sorted chestnuts.

[0024] The electronic scale 1 has fixed rings 6 on both the front and rear sides. A lower clamping ring 7 is fixedly installed at the bottom of the outer wall of the fixed ring 6.

A sliding hole 13 is provided on the top left side of the upper clamping ring 8. A fixed rod 14 is fixedly installed at the left end of the outer wall of the fixed ring 6. The bottom end of the fixed rod 14 is inserted into the sliding hole 13. The side wall of the fixed rod 14 and the inner side wall of the sliding hole 13 slide against each other.

[0025] Specifically, rubber pads are fixedly installed on the top of the lower clamping ring 7 and the bottom of the upper clamping ring 8.

[0026] The rubber pads increase the frictional fixation effect of the top of the lower clamping ring 7 and the bottom of the upper clamping ring 8 on the bag body.

[0027] Specifically, buffer plates 15 are fixedly installed on both the left and right ends of the inner sidewall of the fixed ring 6. The ends of the buffer plates 15 are inclined, and a rubber layer 16 is fixedly installed on the top of the buffer plates 15.

[0028] The buffer plate 15 and the rubber layer 16 can reduce the impact of chestnuts falling and reduce the noise.

[0029] Specifically, the inner wall of the upper clamping ring 8 does not contact the outer wall of the fixing ring 6.

[0030] Specifically, a pressure ring 17 is integrally formed on the threaded sidewall of the bolt 12, the bottom of the pressure ring 17 is tightly fitted to the top of the inner ring of the bearing 11, and a nut 18 is screwed onto the threaded sidewall of the bolt 12, the top of the nut 18 is tightly fitted to the bottom of the inner ring of the bearing 11.

[0035] Lower clamping ring 7: inner diameter 80mm, outer diameter 120mm, thickness 15mm, made of stainless steel. It works with the upper clamping ring 8 at the bottom to hold the bag body. The top is equipped with a rubber pad (thickness 3mm, made of natural rubber) to increase friction and fixation.

[0036] Upper clamping ring 8: inner diameter 80mm, outer diameter 120mm, thickness 15mm, material is stainless steel. The top right side is provided with a threaded hole 9 (hole diameter 8mm, depth 10mm) for screwing with bolt 12. The left side is provided with a sliding hole 13 (hole diameter 10mm, depth 15mm) for inserting the fixing rod 14. The inner side wall does not contact the outer side wall of the fixing ring 6.

[0037] Threaded hole 9: Located on the top right side of the upper clamping ring 8, with a diameter of 8mm and a depth of 10mm, for screwing with bolt 12.

[0038] Mounting ring 10: inner diameter 15mm, outer diameter 25mm, thickness 5mm, made of stainless steel, fixed to the right end of the outer wall of the fixing ring 6, and the inner wall is fixed to the bearing 11.

[0041] Fixed rod 14: 10mm in diameter, 60mm in length, made of stainless steel, with its bottom end inserted into the sliding hole 13, and its side wall sliding against the inner side wall of the sliding hole 13, serving as a guide.

[0042] Buffer plate 15: 80mm in length, 20mm in width, and 5mm in thickness, made of plastic, with an inclined end and a rubber layer 16 (2mm thick, made of natural rubber) fixed on top, used to reduce the impact and noise of chestnuts falling.

[0043] Rubber layer 16: 2mm thick, made of natural rubber, fixed to the top of the buffer plate 15 to enhance the buffering and noise reduction effect.

[0044] Pressure ring 17: 15mm in diameter, 3mm in thickness, made of 45# steel, integrally formed on the side wall of the threaded rod of bolt 12, with the bottom tightly fitted to the top of the inner ring of bearing 11 for easy assembly.

[0045] Nut 18: Hexagonal, 10mm inner diameter, made of 45# steel, screwed onto the side wall of the threaded rod of bolt 12, with its top tightly fitted to the bottom of the inner ring of bearing 11, and can be turned by wrench.

[0046] Working principle: When in use, the top of the bag (such as a chestnut packaging bag) is placed on the top of the lower clamping ring 7. Then, the bolt 12 is turned so that it drives the upper clamping ring 8 to move downward and press it onto the bag, fixing it to the bottom of the fixing ring 6. The chestnut is placed on the top of the electronic scale 1. After weighing, the motor 2 is controlled to rotate forward and backward according to the displayed weight, so that the chestnut is sorted into the fixing ring 6 by the ring body 5.

However, those skilled in the art who understand the principle of the above patent can clearly understand the specifics of its power mechanism, power supply system and control system.

[0048] This solution features a motor-controlled ring at the top of the electronic scale. After the chestnuts are weighed, the motor can rotate forward and backward to sort them to the desired positions, eliminating the need for manual sorting. This makes the operation convenient and improves practicality. Additionally, there are fixing rings on both sides of the electronic scale, with bags that can be installed at the bottom of the fixing rings to receive the sorted chestnuts.
