Abstract
Description
Technical Field
[0001] This utility model belongs to the field of seed treatment technology, specifically a drying device for zucchini seeds after coating. Background Technology
[0002] Seed coating is a high-tech method developed in the mid-1980s to promote increased agricultural production and harvests. Seeds coated with seed coating agents can quickly absorb water and swell after sowing. As the embryo inside the seed gradually develops and the seedling continues to grow, the seed coating agent slowly releases its various active ingredients, which are gradually absorbed by the seedling, thereby achieving the purpose of preventing and controlling seedling diseases and pests, promoting growth and development, and increasing crop yield.
[0003] Currently, after coating zucchini seeds using a coating machine, the coated seeds are quite moist and cannot be stored directly. They are generally dried before storage; otherwise, the seeds will clump together and mold, becoming inferior seeds and affecting the germination rate after sowing. However, existing dryers directly pour the zucchini seeds into the dryer for heating and drying, which causes the coating agent to stick together and clump during drying, adversely affecting subsequent seed packaging and sowing. Therefore, there is a need to develop a post-coating drying device for zucchini seeds that can prevent the coated seeds from sticking together and clumping during the drying process. Utility Model Content
[0004] To address the above technical problems, this utility model provides a zucchini seed drying device that can prevent seeds from sticking together and clumping during the drying process, thus solving the problem of zucchini seeds sticking together and clumping during the drying process of existing coated seed dryers.
[0005] To solve the above technical problems, the technical solution of this utility model is as follows: a zucchini seed coating and drying device, including a base, supports, and a drying cylinder. Two supports are provided, and the bottom of the two supports is fixedly connected to the upper end of the base. A sealing cover is hinged to the top of the drying cylinder. Connecting rods are symmetrically fixedly connected to both sides of the upper end of the drying cylinder. The other ends of the two connecting rods are rotatably connected to the upper side of the supports. A roller is rotatably connected inside the drying cylinder. A motor is fixedly connected to the bottom of the drying cylinder, and the roller is driven by the motor. A drying mechanism is provided on the lower side of the drying cylinder. The drying cylinder is inclined. A hydraulic cylinder is hinged to the upper end of the base. The output end of the hydraulic cylinder is hinged to the inclined upward side of the bottom of the drying cylinder. A limit block is fixedly connected to the upper end of the base, and one side of the limit block contacts the outer wall of the drying cylinder.
[0006] Furthermore, a plurality of mounting seats are fixedly connected to the inner wall of the drying drum, and the plurality of mounting seats are arranged along the circumferential direction of the drying drum. Rollers are rotatably connected to the mounting seats. The outer wall of the drum contacts the rollers. A rotating shaft is fixedly connected to the inner axis of the drum. A reinforcing connecting rod is fixedly connected between the rotating shaft and the inner wall of the drum. One end of the rotating shaft extends through the bottom of the drum and is rotatably connected to the bottom of the drying drum. The output end of the motor is fixedly connected to the rotating shaft.
[0007] Furthermore, the drying mechanism includes a hot air generator, a hot air outlet pipe, and an exhaust pipe. The hot air generator is fixedly connected to the bottom of the drying cylinder. The hot air outlet pipe is located on the lower side and bottom of the drying cylinder. The hot air outlet pipe is located between the drying cylinder and the drum and is fixedly connected to the inner wall of the drying cylinder.

[0016] The present invention will be further described below with reference to the accompanying drawings.
[0017] like Figures 1 to 3 The device shown is a zucchini seed coating and drying device, comprising a base 1, supports 2, and a drying cylinder 3. Two supports 2 are provided, with their bottoms fixedly connected to the upper end of the base 1. The drying cylinder 3 is a hollow cylinder with an open top. A sealing cap 4 is hinged to the top of the drying cylinder 3. Connecting rods 5 are symmetrically fixed to both sides of the upper end of the drying cylinder 3, and the other ends of both connecting rods 5 are rotatably connected to the upper side of the supports 2. A roller 6 is rotatably connected inside the drying cylinder 3. The roller 6 is also a hollow cylinder with an open top, and its outer diameter is smaller than the inner diameter of the drying cylinder 3. The sidewalls of the roller 6 are connected to the bottom... The walls are provided with several ventilation holes for gas to enter and exit. A motor 7 is fixedly connected to the bottom of the drying cylinder 3. The drum 6 is driven by the motor 7. A drying mechanism is provided on the lower side of the drying cylinder 3. The drying cylinder 3 is tilted. A hydraulic cylinder 8 is hinged to the upper end of the base 1. The output end of the hydraulic cylinder 8 is hinged to the side of the bottom of the drying cylinder 3 that is tilted upward. When the output end of the hydraulic cylinder 8 extends, it can drive the drying cylinder 3 to gradually reduce the tilt angle until the horizontal position of the upper end of the drying cylinder 3 is lower than the horizontal position of the bottom end. A limit block 9 is fixedly connected to the upper end of the base 1. One side of the limit block 9 is in contact with the outer wall of the drying cylinder 3.
[0018] To facilitate the stable rotation of the drum 6 inside the drying cylinder 3, several mounting seats 10 are fixedly connected to the inner wall of the drying cylinder 3. The mounting seats 10 are arranged in a circle along the circumference of the drying cylinder 3. Rollers 11 are rotatably connected to the mounting seats 10. The outer wall of the drum 6 contacts the rollers 11. A rotating shaft 12 is fixedly connected to the inner axis of the drum 6. A reinforcing connecting rod 13 is fixedly connected between the rotating shaft 12 and the inner wall of the drum 6. There are two sets of reinforcing connecting rods 13, with three rods evenly spaced in each set, for a total of six rods. One end of the rotating shaft 12 extends through the bottom of the drum 6 and is rotatably connected to the bottom of the drying cylinder 3. The output end of the motor 7 is fixedly connected to the rotating shaft 12.
[0019] To dry the coated seeds placed inside the drum 6, the drying mechanism includes a hot air generator 14, a hot air outlet pipe 15, and an exhaust pipe 16. The hot air generator 14 is fixedly connected to the bottom of the drying drum 3. The hot air outlet pipe 15 is located on the lower side and bottom of the drying drum 3. The hot air outlet pipe 15 is located between the drying drum 3 and the drum 6 and is fixedly connected to the inner wall of the drying drum 3. The exhaust pipe 16 is fixedly connected to the sealing cover 4. The output end of the hot air generator 14 is connected to the input end of the hot air outlet pipe 15. The hot air entering the drying drum 3 is finally discharged through the exhaust pipe 16 on the sealing cover 4.
[0020] In order to guide the hot air to blow onto the coated seeds inside the drum 6, the hot air outlet pipe 15 is provided with several air outlets, all of which are oriented towards the drum 6.
[0021] In order to maintain the tilted state of the drying cylinder 3, when the hydraulic cylinder 8 is in the initial state, the tilt angle of the drying cylinder 3 is 30 degrees, and the outer side of the drying cylinder 3 is in contact with the inclined surface of the limiting block 9.
[0022] The specific working process of this utility model is as follows:
[0023] Open the sealing cover 4, add the coated zucchini seeds from the top of the drying cylinder 3 into the drum 6, then close the sealing cover 4, start the motor 7 and hot air generator 14, and the device begins the drying operation. The hot air generator 14 continuously delivers hot air into the hot air outlet pipe 15, blowing it onto the drum 6 inside the drying cylinder 3. The hot air passes through the vent holes on the side wall of the drum 6 and blows onto the coated zucchini seeds inside the drum 6, drying the coating skin covering the zucchini seeds. At the same time, the motor 7 drives the rotating shaft 12 to rotate, thereby driving the drum 6 to rotate inside the drying cylinder 3. Since the drum 6 is tilted with the drying cylinder 3, the zucchini seeds inside the drum 6 are constantly turned over by gravity as the drum 6 rotates, making the hot air blown more evenly. Finally, the hot air carrying moisture is discharged from the drying cylinder 3 through the exhaust pipe 16. After a period of time, the drying operation is completed. Turn off the motor 7 and the hot air generator 14, open the sealing cover 4, and control the output end of the hydraulic cylinder 8 to extend, gradually lifting one side of the bottom of the drying cylinder 3, so that the horizontal position of the bottom of the drying cylinder 3 gradually rises until the top position of the drying cylinder 3 is lower than the bottom position. Pour out the coated and dried zucchini seeds in the drum 6. After completely pouring out the seeds in the drum 6, control the output end of the hydraulic cylinder 8 to shorten until the side wall of the drying cylinder 3 is close to and against the inclined surface of the limit block 9. Stop the hydraulic cylinder 8, and add the coated zucchini seeds to be dried again according to the above steps to continue the drying operation.
