The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0024] Example 1

[0025] like Figs. 1-4 As shown, this embodiment proposes a mixer discharge gate cleaning device, which includes a mixing box 1, a mixing chamber 2 inside the mixing box 1, and a discharge port 3 at the bottom of the mixing box 1, the mixing chamber 2 communicating with the discharge port 3; it also includes a discharge gate 4, one side of which is rotatably connected to one side wall of the bottom of the mixing box 1, the discharge gate 4 being used to open or cut off the discharge port 3; it also includes a housing 5, which surrounds the mixture of the mixing box 1 and the discharge gate 4; and the inner wall of the housing 5 has a gap between it and the mixing box 1 and the discharge gate 4 respectively; it also includes an air jet pipe 6, which is installed on the inner wall of the housing 5; and it also includes an air jet nozzle 7, which communicates with the air jet pipe 6 and is positioned toward the gap between the discharge port 3 and the discharge gate 4.

[0026] A mixing chamber 2 is provided inside the mixing box 1. The mixing chamber 2 is used to place the mixing components, which are used to stir the materials. The shape of the discharge port 3 is not limited. In this embodiment, the discharge port 3 is a rectangular opening. One side of the discharge door 4 is rotatably connected to one side wall of the bottom of the mixing box 1, for example, by a pivot connection. The discharge door 4 is rotatable relative to the bottom of the mixing box 1. When the discharge door 4 blocks the discharge port 3, the discharge port 3 is cut off. When the discharge door 4 is turned open and does not block the discharge port 3, the discharge port 3 is opened. The opened discharge port 3 is used to discharge the materials, allowing the materials to enter the transition hopper.

[0027] The housing 5 is made of metal and surrounds the combination of the mixing chamber 1 and the discharge gate 4. In this embodiment, it is used to install the jet pipe 6. The jet pipe 6 is installed on the inner wall of the housing 5 and compressed air flows through the jet pipe 6. It also includes a jet nozzle 7, which is arranged toward the gap between the discharge port 3 and the discharge gate 4. Preferably, the jet nozzle 7 is a fan-shaped jet nozzle, that is, the gas ejected from the jet nozzle 7 is ejected in a fan-shaped path.

[0028] Specifically, the jet duct 6 is arranged around the gap between the discharge port 3 and the discharge gate 4. There are multiple jet nozzles 7, which are evenly spaced along the path of the jet duct 6.

[0029] like Figs. 1-4 As shown, more specifically, the mixer discharge gate cleaning device also includes an air inlet pipe 8, which is confined outside the combination of the housing 5, the mixing box 1 and the discharge gate 4, and is connected to the inlet of the jet pipe 6; it also includes a solenoid valve 9, which is disposed on the air inlet pipe 8 and is used to open or close the air inlet pipe 8.

[0030] The intake pipe 8 is used to connect the air source to the jet pipe 6, wherein the air source can be an air compressor or a compressed air storage tank; in this embodiment, in order to control the opening and closing of the intake pipe 8, a solenoid valve 9 is provided. The solenoid valve 9 is connected to the central control room, and the central control room controls the solenoid valve 9 to open and close, thereby opening and closing the intake pipe 8.

[0031] The mixer is an important piece of equipment in the feed production process. Materials to be mixed enter the mixer, and after mixing, the mixer's discharge gate opens and discharges the material into the transition hopper. Often during the discharge process, material tends to stick to the edges of the discharge gate. When the discharge gate and discharge port are locked together, the following consequences can occur: 1. The discharge gate and discharge port cannot completely seal, resulting in material leakage; 2. Uneven material adhering to the edges of the discharge gate causes uneven stress on the sealing strip, shortening its lifespan.

[0032] If the uneven material adhering to the edge of the unloading door is cleaned by opening the shell, mixing box, and unloading door, it will greatly reduce production efficiency and subsequent maintenance costs.

[0033] Therefore, the technical problem in the prior art is that there is an urgent need to propose a mixer discharge gate cleaning device that can easily clean the material adhering to the edge of the discharge gate.

[0034] When in use, when the mixer discharge gate 4 approaches the discharge port 3, the central control room sends a signal to the solenoid valve 1, the solenoid valve is energized, and the air intake pipe 8 is opened. High-pressure compressed air is introduced into the jet pipe 6 and blows air through the jet nozzle 7 into the gap between the discharge port 3 and the discharge gate 4, thereby blowing away the material stuck to the edge of the discharge gate 4, the material stuck to the sealing strip of the discharge gate 4, and the material stuck to the edge of the discharge port 3.

[0035] In this embodiment, the compressed air flowing in the air inlet pipe 8 can act on the gap between the discharge port 3 and the discharge gate 4 through the jet nozzle 7. During the process of the discharge gate 4 and the discharge port interlocking, the material adhering between the discharge port 3 and the discharge gate 4 can be blown away. The material adhering between the discharge port 3 and the discharge gate 4 includes the material adhering to the edge of the discharge gate 4, the material adhering to the sealing strip of the discharge gate 4, and the material adhering to the edge of the discharge port 3. Therefore, this embodiment solves the technical problems existing in the prior art and urgently needs to provide a mixer discharge gate cleaning device that can easily clean the material adhering to the edge of the discharge gate.

[0036] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
