Detailed implementation mode

[0031] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] As Figures 1 to 2 shown is a stuffing mixer, which includes a machine body 1. A mixing hopper 2 and a mixing drive device 3 are arranged on the machine body 1. A horizontally arranged stirrer 5 is arranged in the mixing hopper 2, and the stirrer 5 is power-connected to the mixing drive device 3. An openable engine room door 15 is arranged on the machine body 1 at a position corresponding to the mixing drive device 3, and an electric control box 16 is arranged on the inner side of the engine room door 15.

[0033] A box cover support 6 is fixed to the rear of the mixing hopper 2. A box cover shaft 7 is rotatably connected to the box cover support 6. A box cover arm 8 is fixed to the box cover shaft 7. The front end of the box cover arm 8 is rotatably connected to the top of the hopper cover 4. The hopper cover 4 is located above the mixing hopper 2. A ring-shaped sealing ring is arranged at the bottom of the hopper cover 4. After the hopper cover 4 covers the mixing hopper 2, the airtightness of the inside of the mixing hopper 2 after vacuum pumping is ensured. In this embodiment, a vacuum pumping pipe orifice is arranged on the hopper cover 4, which is convenient for connecting with a vacuum pump through a pipeline.

[0034] One end of the box cover shaft 7 is connected to an opening drive device 9. The opening drive device 9 is arranged inside the machine body 1. As Figure 3 and 4 shown, the opening drive device 9 includes a shaft end frame 901, an opening cylinder 902 and a limit rod 903. The shaft end frame 901 is fixed to the machine body 1. The box cover shaft 7 is rotatably connected to the shaft end frame 901. The tail of the opening cylinder 902 is rotatably connected to a box cover cylinder tail seat 904. The box cover cylinder tail seat 904 is fixed to the machine body 1. The head of the opening cylinder 902 is connected to the box cover shaft 7 through a box cover swing rod 905. One end of the box cover swing rod 905 is fixed to the box cover shaft 7, and the other end is rotatably connected to the head of the opening cylinder 902; the limit rod 903 is slidably connected to the shaft end frame 901. One end of the limit rod 903 is connected to a limit control cylinder 906. The limit control cylinder 906 is installed inside the machine body 1.

[0035] When the opening cylinder 902 retracts and drives the hopper cover 4 to open by driving the box cover swing rod 905 to swing, at this time the box cover swing rod 905 will move above the limit rod 903. Then, after the limit control cylinder 906 drives the limit rod 903 to extend, the limit rod 903 will limit the box cover swing rod 905 from rotating downward, thereby avoiding accidental closing of the hopper cover 4 when a fault occurs in the air circuit of the stuffing mixer.

[0036] As Figure 5 and 7As shown, the stirrer 5 includes two stirring shafts 501 arranged side by side. A plurality of stirring blades 502 are provided on the outer wall of the stirring shaft 501. One end of the stirring shaft 501 is sealingly and rotatably connected to the shaft tail seat 503, and the shaft tail seat 503 is installed on the stirring tank 2. The other end of the stirring shaft 501 is inserted into the power transmission shaft 504 and fixed by a pin shaft, thereby realizing the detachable connection between the stirring shaft 501 and the power transmission shaft 504. The power transmission shaft 504 is sealingly and rotatably connected in the shaft cover 505, and a Gleitring is provided as a seal at the position where the power transmission shaft 504 is rotatably connected to the shaft cover 505. The shaft cover 505 is installed on the stirring tank 2, and the power transmission shaft 504 is power-connected to the stirring drive device 3 at the end facing away from the stirring shaft 501.

[0037] The stirring drive device 3 includes a shaft seat plate 301 and a drive motor 302. The shaft seat plate 301 is fixed on the stirring tank 2. The shaft seat plate 301 is concave, and the concave surface of the shaft seat plate 301 faces the stirring tank 2. The concave surface of the shaft seat plate 301 and the stirring tank 2 enclose an inspection passage 303. A shaft seat 304 is provided on the shaft seat plate 301, and the power transmission shaft 504 is rotatably connected to the shaft seat 304 through a bearing assembly; the drive motor 302 is installed in the machine body 1, and the power output end of the drive motor 302 is power-connected to the power transmission shaft 504 through a chain assembly 305. The chain assembly 305 mainly includes a chain and a sprocket. The sprocket is installed on the power transmission shaft 504, and the chain meshes with the sprockets on each power transmission shaft 504 and the drive motor 302 in turn in the form as Figure 7 shown.

[0038] The inspection passage 303 penetrates through the machine body 1, which facilitates directly detecting the sealing performance at the position of the shaft cover 505 from the outside of the machine body 1; at the same time, the inspection passage 303 separates the shaft seat 304 from the stirring tank 2, preventing the lubricating oil of the bearing assembly in the shaft seat 304 from entering the stirring tank 2 and contaminating the filling.

[0039] In this embodiment, as Figure 8 shown, detachable sealing plates 306 are provided at both ends of the inspection passage 303. The sealing plates 306 are provided with mesh holes by themselves, and the sealing plates 306 are fixed on the machine body 1 by bolts.

[0040] As Figure 9 and 10 shown, the stirring tank 2 is provided with a discharge port at the end far from the stirring drive device 3. An openable discharge gate 10 is provided outside the discharge port. A sealing rubber strip is provided at the contact position between the discharge gate 10 and the discharge port. A gate shaft 11 is fixed at the top of the discharge gate 10. Both ends of the gate shaft 11 are rotatably connected to the plate shaft seat 12, and the plate shaft seat 12 is fixed on the outer side wall of the stirring tank 2. One end of the plate shaft seat 12 is connected to the gate drive device 13.

[0041] The ram drive device 13 includes a ram cylinder 1301. The ram cylinder 1301 is arranged in the machine body 1, and the drive end of the ram cylinder 1301 is connected to the ram shaft 11 through a connecting rod group. The connecting rod group includes a first connecting rod 1302, a second connecting rod 1303, and a third connecting rod 1304 that are sequentially rotatably connected. The first connecting rod 1302 is fixedly connected to the ram shaft 11. The third connecting rod 1304 is fixed to the connecting rod shaft 1305. The connecting rod shaft 1305 is rotatably connected to the machine body 1. One end of the connecting rod shaft 1305 away from the third connecting rod 1304 is fixed to a fourth connecting rod 1306. The fourth connecting rod 1306 is rotatably connected to the telescopic end of the ram cylinder 1301. The body of the ram cylinder 1301 is rotatably connected to the machine body 1.

[0042] In this embodiment, as Figure 11 shown, a protective cover 14 is provided above the discharge ram 10. The protective cover 14 is installed on the mixing hopper 2.

[0043] The above-described embodiments are only descriptions of the preferred modes of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
