[0022] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0023] See also Figures 1-4 A pet food raw material mixing device comprises a base 10, on which an outer barrel assembly 20 is arranged, the front side of the outer barrel assembly 20 is open, and an inner barrel assembly 30 is inserted into the outer barrel assembly 20; the outer barrel assembly 20 comprises an outer barrel body 210 with an opening at the front side, a rotating cylinder body 220 is rotatably arranged in the outer barrel body 210, and the rotating cylinder body 220 is opened at both sides; the inner barrel assembly 30 comprises an inner barrel body 310 with an opening at the front side, and the inner barrel body 310 is movably inserted in the rotating cylinder 220, the front side of the inner barrel body 310 is detachably connected to the barrel cover 300, a stirring shaft 320 is rotatably arranged in the inner barrel body 310, the rear end of the stirring shaft 320 passes through the rear side wall of the inner barrel body 310 and extends backward, and the rear side of the outer barrel body 210 is provided with a transmission head 240 that is transmission-connected to the rear end of the stirring shaft 320; the outer barrel body 210 is provided with a limit assembly 40 for limiting the inner barrel body 310.

[0024] Based on the above embodiment, when in use, the barrel cover 300 is opened, and materials are put into the inner barrel body 310 . Under the action of the driving assembly driving the transmission head 240 to drive the stirring shaft 320 , the stirring shaft 320 stirs and mixes the materials in the inner barrel body 310 .

[0025] When the inner barrel assembly 20 needs to be disassembled at a later time, the inner barrel assembly 20 can be pulled out from the back to the front to the outside by releasing the limit lock of the limit assembly 40 to achieve disassembly and separation.

[0026] The utility model can effectively ensure the stability of the inner barrel assembly during the rotation process through the cooperation between the inner barrel assembly and the outer barrel assembly, and at the same time, the plug-in assembly method can be easily disassembled.

[0027] In the present invention, stirring rods 321 are evenly distributed on the stirring shaft 320 .

[0028] See also Figures 2 to 4, a circular limiting groove 312 is provided on the outer wall at the rear side of the inner barrel body 310. The limiting component 40 includes a first cylinder 410 fixedly arranged on the outer barrel body 210. A limiting rod 420 is fixedly arranged on the cylinder shaft of the first cylinder 410. The end of the limiting rod 420 far from the first cylinder 410 is movably inserted into the circular limiting groove 312. That is, by inserting the limiting rod 420 into the limiting groove 312, the front-back movement of the inner barrel body 310 is restricted. When it is necessary to disassemble and extract the inner barrel body 310, the first cylinder 410 drives the limiting rod 420 to disengage from the limiting groove 312.

[0029] Furthermore, the cross-section of the circular limiting groove 312 is in an arc structure, and the end of the limiting rod 420 far from the first cylinder 410 is in a spherical structure. The spherical end cooperates with the arc-shaped circular limiting groove, which can reduce frictional interference during the rotation of the inner barrel body 310 relative to the limiting rod 420, so as to improve the running stability.

[0030] Furthermore, two groups of the limiting components 40 are respectively arranged up and down.

[0031] See Figure 2 and Figure 3 , a positioning groove 230 extending in the front-back direction is provided on the inner wall surface of the rotating cylinder body 220. The positioning groove 230 is open at the front side. A positioning rib 311 that is movably inserted into the positioning groove 230 is provided on the outer wall of the inner barrel body 310. This structure can realize the synchronous relative rotation of the rotating cylinder body 220 and the inner barrel body 310 with respect to the outer barrel body 210.

[0032] Furthermore, an annular gear is provided on the rotating cylinder body 220. The annular gear and the rotating cylinder body 220 are coaxially arranged. A driving motor is arranged inside the outer barrel body 210. A driving gear is installed on the motor shaft of the driving motor. The driving gear meshes with the annular gear. So as to realize that the driving motor drives the rotating cylinder body 220 to rotate, and the rotating cylinder body 220 drives the inner barrel body 310 to rotate relative to the outer barrel body 210. The mixing efficiency can be effectively improved.

[0033] See Figure 3 , a transmission groove 322 is provided at the rear end of the stirring shaft 320. The transmission head 240 is inserted into the transmission groove 322.

[0034] Furthermore, a driving component is fixedly installed on the outer barrel body 210. The driving component includes a motor and a speed reducer that is in transmission connection with the motor. The power output shaft of the speed reducer is in transmission connection with the transmission head 240. During actual operation, the motor drives the speed reducer to operate, the speed reducer drives the transmission head 240 to rotate, and then the stirring shaft 302 is driven by the transmission head 240 to rotate.

[0035] SeeFigure 3 , a mating sleeve 330 is rotatably provided on the rear side wall surface of the bucket lid 300, and the front end of the stirring shaft 320 is inserted and mated with the mating sleeve 330. The function of the mating sleeve 330 is to perform positioning and mating with the front end of the stirring shaft 320, form a support for the front end of the stirring shaft 320, and enhance the stability of the stirring shaft 320.

[0036] Furthermore, a convex ring is provided on the rear wall surface of the bucket lid 300, and the mating sleeve 330 is mounted in the convex ring by means of a bearing.

[0037] See Figure 3 and Figure 4 , a first mounting hole 313 is provided on the rear side wall surface of the inner barrel body 310, the rear end of the stirring shaft 320 is inserted into the first mounting hole 313, and a first bearing 340 is provided between the first mounting hole 313 and the stirring shaft 320.

[0038] See Figure 3 , a plurality of second bearings 200 are provided between the rotating cylinder body 220 and the outer barrel body 210.

[0039] See Figures 1 to 4 , the base 10 is provided with a column 110 and a telescopic element 120 is hinged, the telescopic rod of the telescopic element 120 is hinged to the outer barrel body 210, and the column 110 is hinged to the outer barrel body 210.

[0040] In the present utility model, the telescopic element 120 is a cylinder. The cylinder can drive the outer barrel assembly 20 and the inner barrel assembly 30 to rotate around the hinge axis of the column 110 and the outer barrel body 210, so as to achieve tilting and facilitate pouring out the materials located in the inner barrel body 310.

[0041] In the present utility model, the bucket lid 300 is detachably connected to the inner barrel body 310 by a plurality of bolts or a plurality of hinge buckles.
