Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Refer to the instruction manual Figure 1-5 The utility model provides a chute gate, comprising a chute frame 1 and a gate member 2 arranged in the chute frame 1, wherein the chute frame 1 is provided with a detection component for judging whether there is material circulation;

[0026] like Figure 1 , 3As shown in Figure 5, the detection component includes a high flow channel 3 and a low flow channel 4 opened inside the chute frame 1 and a first pressure sensor 5 embedded in the rear side of the gate member 2, and the first pressure sensor 5 is externally mounted with a first material plate 6 located on the rear side of the gate member 2 and used for contacting the material; the high flow channel 3 is arranged at the top of the low flow channel 4, and a second pressure sensor 7 is embedded inside one end of the low flow channel 4 close to the high flow channel 3, and the second pressure sensor 7 is externally mounted with a second material plate 8 for contacting the material.

[0027] In order to adjust the rotation of the gate member 2, a driving assembly for driving the gate member 2 to open and close is provided on the outside of the chute frame 1;

[0028] like Figure 2 , 4 As shown in Figures 1 and 5, the driving assembly includes two support shafts 9 respectively installed on both sides of the top of the gate member 2, and the ends of the two support shafts 9 away from the gate member 2 penetrate the chute frame 1 and are movably connected to the chute frame 1 through bearings; one of the support shafts 9 is provided with a slave gear 10 on the outside, and the front end of the slave gear 10 is meshed with a main gear 11, and the meshed slave gear 10 is driven to rotate by the main gear 11, so that the gate member 2 can be turned inward or outward by the support shaft 9. When turning inward, the gate member 2 can intercept and block the chute frame 1, and when turning outward, the gate The plate member 2 does not block the material and facilitates the flow of the material. A mounting bracket 12 is installed on the side of the chute frame 1 close to the main gear 11. A motor 13 is installed on the side of the mounting bracket 12 corresponding to the main gear 11. The output shaft of the motor 13 is fixed to the main gear 11. The motor 13 is supported and fixed by the mounting bracket 12 to ensure the stability of the motor 13. Then, the main gear 11 is driven to rotate by the motor 13, and the main gear 11 then drives the support shaft 9 to rotate by the meshing slave gear 10, thereby the gate member 2 can be flipped and adjusted.

[0029] like Figure 1 , 3 As shown in FIG. 5 , a controller 14 is installed on one side of the top end of the chute frame 1 for controlling the motor 13 , the first pressure sensor 5 and the second pressure sensor 7 . By setting the controller 14 , the motor 13 , the first pressure sensor 5 and the second pressure sensor 7 can be easily regulated.

[0030] like Figure 1 and 3As shown, the outside of the gate member 2 is in contact with the inner wall of the chute frame 1, and is used to intercept the material. By operating the gate member 2 to fit closely with the chute frame 1, the gate member 2 can completely block the chute frame 1, thereby effectively improving the interception effect of the utility model. The bottom end of the gate member 2 is arranged at the top of one end of the high flow channel 3 close to the low flow channel 4. By arranging the bottom end of the gate member 2 at the high flow channel 3, the material can fall from a high place onto the second material plate 8 in the low flow channel 4, so that the second pressure sensor 7 can detect the pressure.

[0031] The staff connects the chute frame 1 with the corresponding equipment, and then transports the material through the chute frame 1. When the material in the chute frame 1 contacts the first material plate 6 on the gate member 2, the first pressure sensor 5 is subjected to pressure and transmits the detection information to the controller 14. The controller 14 starts the motor 13 to drive the main gear 11 to rotate. The main gear 11 drives the gate member 2 to turn outward through the meshing slave gear 10, thereby allowing the material to flow;

[0032] Then, through the high flow channel 3 and the low flow channel 4 with a height difference, the material at the high flow channel 3 will fall onto the second material plate 8 at the low flow channel 4, so that the second pressure sensor 7 can be pressurized, and thereby it can be detected whether there is still material flowing from the high flow channel 3. When the pressure sensor in the second material plate 8 is not subjected to pressure, the controller 14 starts the motor 13 to drive the gate member 2 to flip inward, so that the gate member 2 can intercept the material, thereby realizing the automatic opening and closing of the gate member 2, thereby improving the practicality and intelligence level of the utility model.

[0033] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
