[0018] The utility model will be further described below in conjunction with the accompanying drawings.

[0019] Example

[0020] refer to Figures 1 to 7 A granary rat and insect proof electric baffle comprises a positioning frame 1, a movable baffle 2 and a driving motor 4.

[0021] Specific reference Figure 5 and Figure 6 The positioning frame 1 is a long rectangular structure with a transverse positioning groove 11 therein. In this embodiment, the positioning frame 1 is a shell-shaped structure formed by connecting a top plate 12, two side plates 13 located on both sides of the top plate 12, and an end plate 14 located at one end of the top plate 12. The end of the positioning frame 1 away from the end plate 14 forms a socket for the movable baffle 2 described below to be inserted into the positioning groove 11, and the bottom of the positioning frame 1 forms a bottom opening for the roller 3 described below to extend out of the positioning groove 11. The positioning frame 1 of this structure adopts a semi-sealed shell-shaped method, which can effectively prevent mice from entering the positioning frame 1.

[0022] The movable baffle 2 is a long rectangular plate structure, and a roller 3 is provided at the bottom. Figures 5 to 7 The movable baffle plate 2 has a long back groove 21 near the middle of the back side, the back groove 21 is arranged horizontally, and a long rack 22 is arranged on the bottom surface thereof. The movable baffle plate 2 is arranged horizontally, and one end thereof is inserted into the positioning groove 11 and can move horizontally along the positioning groove 11, so that the movable baffle plate 2 can extend out of the positioning frame 1 or retract the positioning frame 1.

[0023] The driving motor 4 is a forward and reverse motor, and a gear 5 is coaxially provided on its output shaft 41. The driving motor 4 is fixed near the positioning frame 1 and is arranged corresponding to the back side of the movable baffle 2. The gear 5 is inserted into the back groove 21 and meshed with the rack 22. The driving motor 4 can drive the rack 22 by the gear 5, and then push the movable baffle 2 to move.

[0024] In the above structure, the gear 5 is meshed with the rack 22. When the driving motor 4 drives the gear 5 to rotate, the gear 5 and the rack 22 are driven to realize the movable baffle 2 to move left and right with the forward and reverse operation of the driving motor 4. The rack 22 is arranged near the middle of the back of the movable baffle 2, rather than on the top or bottom surface of the movable baffle 2, thereby avoiding the meshing connection of the gear 5 and the rack 22 to occupy the top or bottom position of the movable baffle 2, making the overall structure of the positioning frame 1 and the movable baffle 2 very compact. In addition, by being arranged in the back groove 21 to form a shield for the gear 5 and the rack 22, the gear 5 and the rack 22 are prevented from being completely exposed, which plays a certain protective role for the gear 5 and the rack 22, and the operator, and improves the safety and reliability of the operation.

[0025] Furthermore, in this embodiment, a plurality of rollers 6 are vertically spaced apart on the back side of the positioning frame 1 near the movable baffle 2, and the rollers 6 are in rolling contact with the movable baffle 2. Of course, when the movable baffle 2 is longer and moves slower, a plurality of rollers 6 can also be vertically spaced apart on the front side of the positioning frame 1 near the movable baffle 2.

[0026] Furthermore, the present embodiment further includes a ground rail 7, which is a long strip structure and has a guide groove 71 arranged along the length direction. The ground rail 7 is arranged below the positioning frame 1, and one end of the ground rail 7 extends out of the positioning frame 1 to form an extension section 70, and the extension section 70 is used to assist the movable baffle 2 to extend out of the positioning frame 1. In the above structure, when the movable baffle 2 extends out of the positioning frame 1 and moves to the extension section 70, the movable baffle 2 is in the closed state; and the ground rail 7 cooperates with the roller 3 to further ensure that the movable baffle 2 can move smoothly and quickly.

[0027] Furthermore, in this embodiment, both sides of the extension section 70 of the floor rail 7 are provided with insect-proof wire grooves 72 arranged along the length direction. The extension section 70 is arranged directly opposite to the warehouse door during installation, so the insect-proof wire grooves 72 are arranged to take into account the arrangement of the insect-proof wire for the warehouse door, and two insect-proof wire grooves 72 can realize two insect-proof wires to enhance the insect-proof effect.

[0028] Furthermore, in this embodiment, the insect-proof wire groove 72 extends out of the positioning frame 1 at a side away from the guide groove 71. The above structure aims to widen the insect-proof wire groove 72 so that the insect-proof wire groove 72 can form an insect-proof effect on the gap between the insertion position of the positioning frame 1 and the movable baffle 2, thereby preventing pests from crawling into the positioning frame 1 through the gap, or even bypassing the positioning frame 1 and crawling into the granary, thereby reducing the hidden dangers of pests.

[0029] The electric baffle for preventing rats and insects from entering the granary in this embodiment is installed in front of the granary door. Figure 2 As shown, first, a docking port is opened on the wall on one side in front of the warehouse door, and the docking port is used to dock the socket end of the positioning frame 1. After that, the ground rail 7 and the positioning frame 1 pre-installed with the movable baffle 2 and the drive motor 4 are installed. The ground rail 7 passes through the above-mentioned docking port, and its extended section 7 is located on the ground in front of the warehouse door, and the end extends to the wall on the other side in front of the warehouse door. The socket end of the positioning frame 1 is inserted into the docking port and aligned with the docking port to complete the installation. Figure 1 As shown, the drive motor 4 is started, and the drive motor 4 drives the rack 22 through the gear 5 to push the movable baffle 2 to move. The movable baffle 2 moves until the end contacts the wall on the other side of the warehouse door, and the drive motor 4 stops to achieve the blocking of the warehouse door. When the movable baffle 2 needs to be opened, the drive motor 4 is started to run in the reverse direction, and the movable baffle 2 can be retracted into the positioning frame 1 to avoid blocking the warehouse door.

[0030] The above installation method is for when there is enough installation space on the walls on both sides of the granary door, the walls are used to block the two sides of the door, which is equivalent to the two sides of the wall and the movable baffle to enclose and block the door. When the installation space of the walls on both sides of the granary door is narrow, fixed plates can be fixed on both sides of the door to replace the walls on both sides for installation. The height of the fixed plates is required to be higher than the positioning frame 1 to ensure the rat-proof effect.
