Description

Technical Field

[0001] This utility model relates to the field of seed screening and drying technology, and in particular to a screening and drying device with impurity removal function. Background Technology

[0002] Vegetable seeds are seeds used to produce vegetables. They are divided into conventional seeds and hybrid seeds. Conventional vegetable seeds are seeds that grow naturally by the vegetables themselves. Hybrid vegetable seeds are seeds that are pollinated with plants with different characteristics to change their varietal characteristics. Before planting vegetables, the seeds also need to be screened to remove bad seeds.

[0003] Existing patent (publication number: CN220472219U) discloses "an agricultural seed drying device, including a drying box. A partition is fixedly connected to the inner wall of the drying box. Seed discharge holes and impurity screening holes are respectively opened on the upper surface of the partition. A through hole is opened on the upper surface of the drying box, and a movable rod is slidably connected to the inner wall of the through hole. Two symmetrical screening screens are rotatably connected to the bottom end of the movable rod, and the positions of the screening screens correspond to the impurity screening holes. This agricultural seed drying device, by setting up a partition, a movable rod, screening screens, and an electric telescopic rod, uses the electric telescopic rod to drive the movable rod to move up and down reciprocally, thereby causing the two screening screens to vibrate and screen the seeds on the surface of the screening screens. Impurities and unqualified seeds are allowed to pass through the impurity screening holes into a waste box, while the screened seeds enter the bottom of the drying box through the seed discharge holes, thus achieving the purpose of convenient seed screening."

[0004] In the process of developing this application, the inventors discovered the following problems with the prior art: Although the device can use an electric telescopic rod to drive the screening screen plate to shake up and down to complete the seed screening work, it is inconvenient to quickly remove the seeds after screening, which is not conducive to further improving work efficiency.

[0005] Therefore, this application provides a screening and drying device with impurity removal function to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a screening and drying device with impurity removal function. When using this device, it is convenient to remove the screened seeds from the No. 1 storage box after screening.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a screening and drying device with impurity removal function, comprising a fixing mechanism, a first storage frame and a drying box, wherein a reciprocating screw is rotatably arranged inside the drying box, and a first fixing plate is fixedly arranged around both ends of the reciprocating screw, and a fixing frame is fixedly arranged at the lower end of the two first fixing plates, wherein two screens are rotatably arranged inside the fixing frame, and two first fixing frames are fixedly arranged at the lower end of the fixing frame;

[0008] Two electric push rods are fixedly installed at the lower end of the interior of the drying oven. A second fixing plate is fixedly installed at the upper end of each of the two electric push rods. Two connecting rods are connected between the two second fixing plates. Two support frames are slidably arranged around the two connecting rods. A start button is fixedly installed at the rear end of the interior of the drying oven.

[0009] Furthermore, two heating meshes are fixedly installed at the upper part of the interior of the drying box, and a feed inlet is provided at the upper part of the drying box.

[0010] Furthermore, a second fixing frame is fixedly installed on the upper side of one side of the drying box, and a motor is fixedly installed inside the second fixing frame.

[0012] Furthermore, the fixing mechanism includes a main body, and a fixing column is slidably disposed inside the main body.

[0013] Furthermore, a handle is fixedly provided at the lower end of the fixing column, and a spring connects the fixing column and the main body.

[0014] Furthermore, the first storage box is located at the upper end of the main body, and the main body is fixedly located at the front end of the drying box.

[0015] Furthermore, the two support frames are respectively installed inside the two No. 1 fixed frames, and the No. 1 storage box is installed between the two No. 1 fixed frames.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model proposes a screening and drying device with impurity removal function. When in use, the starting motor drives the reciprocating screw to rotate, which in turn drives the two No. 1 fixed plates and the fixed frame to move back and forth, which facilitates the separation of seeds and impurities through the screen. The separated impurities will fall into the interior of the No. 2 storage frame. After screening is completed, the handle is pulled down to move the fixed column away from the handle of the No. 1 storage frame. Then, the No. 1 storage frame is pushed into the interior of the drying chamber. The No. 1 storage frame will press the start button, which will activate the two electric push rods to move the two No. 2 fixed plates, the two connecting rods, and the two support frames downward, which can open the two screens downward, allowing the seeds to fall into the interior of the No. 1 storage frame. This facilitates the rapid completion of seed collection and improves work efficiency.

[0018] 2. The present invention proposes a screening and drying device with impurity removal function. When in use, the fixing column helps to fix the No. 1 storage frame, which helps to prevent the No. 1 storage frame from entering the interior of the drying box when screening impurities. After screening, the handle is pulled down to move the fixing column downward, which helps to disengage the fixing column from the handle of the No. 1 storage frame, making it convenient for the user to push the No. 1 storage frame into the interior of the drying box.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 This utility model provides an embodiment of a screening and drying device with impurity removal function, comprising a fixing mechanism 1, a first storage frame 4, and a drying chamber 2. A reciprocating screw 11 is rotatably mounted inside the drying chamber 2. First fixing plates 13 are fixedly mounted around both ends of the reciprocating screw 11. A fixing frame 9 is fixedly mounted at the lower end of the two first fixing plates 13. Two screens 12 are rotatably mounted inside the fixing frame 9. Two first fixing brackets 3 are fixedly mounted at the lower end of the fixing frame 9. Two electric push rods 16 are fixedly mounted at the lower end of the drying chamber 2. Second fixing plates 15 are fixedly mounted at the upper end of each of the two electric push rods 16. Two connecting rods connect the two second fixing plates 15. Two support frames 18 are slidably arranged around the two connecting rods 14. A start button 17 is fixedly arranged at the rear end of the inside of the drying box 2. Two heating grids 10 are fixedly arranged at the upper end of the inside of the drying box 2. A feed inlet 5 is arranged at the upper end of the drying box 2. A second fixed frame 7 is fixedly arranged at the upper end of one side of the drying box 2. A motor 6 is fixedly arranged inside the second fixed frame 7. A second storage frame 8 is slidably arranged at the lower end of the inside of the drying box 2. Through holes are opened at the front and rear ends of the drying box 2. The two support frames 18 are respectively arranged inside the two first fixed frames 3. The first storage frame 4 is arranged between the two first fixed frames 3. The first storage frame 4 is arranged at the upper end of the main body 101.

[0029] Specifically, the starter motor 6 drives the reciprocating screw 11 to rotate, which in turn drives the two first-fixed plates 13, the fixed frame 9, and the two screens 12 to move back and forth. This facilitates the separation of seeds and impurities inside the fixed frame 9 through the screens 12, thus completing the seed screening process. After screening, the first storage box 4 is pushed into the drying chamber 2, causing it to press the start button 17, which activates the two electric push rods 16. The two electric push rods 16 drive the two second-fixed plates 15, the two connecting rods 14, and the two support frames 18 to move downwards, which helps the two screens 12 to open downwards, allowing the screened seeds to be collected inside the first storage box 4. The two first-fixed frames 3 help drive the two support frames 18 and the first storage box 4 to move with the fixed frame 9. The heating mesh 10 helps to dry the seeds and reduce their moisture content.

[0030] Reference Figure 5 The fixing mechanism 1 includes a main body 101, a fixing column 102 is slidably arranged inside the main body 101, a handle 104 is fixedly arranged at the lower end of the fixing column 102, a spring 103 is connected between the fixing column 102 and the main body 101, and the main body 101 is fixedly arranged at the front end of the drying oven 2.

[0031] Specifically, the main body 101 is conducive to supporting the No. 1 storage frame 4; pulling down the handle 104 causes the fixed column 102 to move downward, so that it is separated from the No. 1 storage frame 4, and then the No. 1 storage frame 4 can be pushed into the interior of the drying box 2, which is conducive to taking out the screened seeds.

[0032] Working principle: When using this device, the seeds to be screened are poured into the drying chamber 2 through the feed inlet 5. The motor 6 is started to drive the reciprocating screw 11 to rotate. The reciprocating screw 11 drives the two No. 1 fixed plates 13 and the fixed frame 9 to move back and forth, which helps to separate the seeds from the impurities through the screen 12. The separated impurities will fall into the No. 2 storage frame 8. After screening, the handle 104 is pulled down to drive the fixed column 102 to disengage from the No. 1 storage frame 4. Then the No. 1 storage frame 4 is pushed into the drying chamber 2. The No. 1 storage frame 4 will press the start button 17, which will start the two electric push rods 16 to drive the two No. 2 fixed plates 15, the two connecting rods 14 and the two support frames 18 to move downward. This will open the two screens 12 downward, allowing the seeds to fall into the No. 1 storage frame 4, thus completing the seed collection work.
