Description

Technical Field

[0001] This utility model relates to the field of feed processing technology, and in particular to a double-layer high-efficiency mixer for feed processing. Background Technology

[0002] Feed is a general term for the food given to animals. It is generally made by mixing and stirring feed ingredients such as wheat, corn, soybean meal, wheat bran, fish meal, chicken meal, bone meal, vegetable oil, and feed additives, and then extruding them into shape.

[0003] Double-layer high-efficiency mixers have been widely used in feed mixing due to their high mixing efficiency. However, existing high-efficiency mixers have a fixed mixing chamber. When mixing feed, the feed ingredients enter the mixing chamber and are continuously pushed towards the discharge port by the stirring and pushing of the spiral agitator. The only way to change the pushing speed of the feed ingredients is to adjust the rotation speed of the spiral agitator.

[0004] The mixing speed of a spiral agitator is positively correlated with the speed at which it pushes feed ingredients. Therefore, it cannot simultaneously increase the mixing speed and decrease the feed pushing speed according to the needs of feed mixing, or simultaneously decrease the mixing speed and increase the feed pushing speed according to the needs of feed mixing.

[0042] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0043] like Figures 1 to 9As shown, a double-layer high-efficiency mixer for feed processing includes a frame 1, an upper mixing bin 2, a lower mixing bin 3, and a feed guide hose 4.

[0044] The upper mixing hopper 2 has a downward-extending discharge port 209 at its tail bottom, and the lower mixing hopper 3 has an upward-extending inlet port 309 at its head top. The two ends of the guide hose 4 are connected to the discharge port 209 and the inlet port 309, respectively. Utilizing the flexibility of the guide hose 4, it can be bent or its angle adjusted when the tilt angle of the upper mixing hopper 2 and the lower mixing hopper 3 is adjusted.

[0045] The frame 1 includes a base plate 101, a first column 102, and a second column 103. The base plate 101 is rectangular. There are two first columns 102 that are symmetrical to each other.

A first round rod 5 is installed between the tops of the two first columns 102, and a fourth round rod 8 is installed between the bottoms of the two first columns 102. There are two second columns 103 that are symmetrical to each other. The two second columns 103 are vertically welded to the top of the two corners at the front of the base plate 101. A second round rod 6 is installed between the tops of the two second columns 103, and a third round rod 7 is installed between the middle parts of the two second columns 103.

[0046] A connecting crossbar 104 is installed between the top of column 2 103 and column 1 102. Diagonal bracing rods 105 are fixed between the top of the base plate 101 and columns 1 102 and 2 103 respectively. The connecting crossbar 104 and diagonal bracing rods 105 improve the stability of columns 1 102 and 2 103.

[0047] The upper mixing chamber 2 includes an upper mixing cylinder 201, an upper cylinder cover 202, an upper stirring shaft 203, and an upper servo motor 204. The upper cylinder cover 202 is installed at the tail end of the upper mixing cylinder 201. The two ends of the upper stirring shaft 203 are rotatably installed at the head center of the upper mixing cylinder 201 and the center of the upper cylinder cover 202, respectively. Multiple upper stirring paddles 207 arranged in a spiral pattern are installed on the upper stirring shaft 203. The power output shaft of the upper servo motor 204 is connected to one end of the upper stirring shaft 203 through a coupling.

[0052] An isolation pipe 11 is fitted on the round rod 5 between the upper mixing bin 2 and the two columns 102. The isolation pipe 11 prevents the upper mixing bin 2 from moving along the axial direction of the round rod 5. An isolation pipe 22 is fitted on the round rod 6 between the upper telescopic cylinder 9 and the two columns 103. The isolation pipe 22 prevents the upper telescopic cylinder 9 from moving along the axial direction of the round rod 6.

[0053] The tail of the upper mixing hopper is hinged to the frame. An upper telescopic cylinder is installed between the frame and the head of the upper mixing hopper. The telescopic movement of the upper telescopic cylinder is used to adjust the tilt angle of the upper mixing hopper, thereby changing the discharge speed of the upper mixing hopper. The rotation speed of the upper stirring shaft in the upper mixing hopper is controlled separately by the upper reduction motor. This allows the mixing speed and discharge speed of the feed in the upper mixing hopper to be controlled separately, and the mixing speed and discharge speed of the feed can be adjusted separately according to the needs of feed mixing.

[0054] The lower mixing chamber 3 includes a lower mixing cylinder 301, a lower cylinder cover 302, a lower stirring shaft 303, and a lower servo motor 304. The lower cylinder cover 302 is installed at the tail end of the lower mixing cylinder 301. The two ends of the lower stirring shaft 303 are rotatably installed at the center of the head of the lower mixing cylinder 301 and the center of the lower cylinder cover 302, respectively. Multiple lower stirring paddles 307 arranged in a spiral pattern are installed on the lower stirring shaft 303. The power output shaft of the lower servo motor 304 is connected to one end of the lower stirring shaft 303 through a coupling. A downwardly extending discharge port 308 is provided at the bottom of the tail of the lower mixing chamber 3. Specifically, the discharge port 308 is located at the bottom of the tail of the lower mixing cylinder 301.

[0055] The head of the lower mixing cylinder 301 is a conical lower stirring section 3011, and the angle between the generatrix of the lower stirring section 3011 and its central axis is 3°~5°, so as to facilitate the discharge of the well-mixed feed; the tail of the lower mixing cylinder 301 is a circular lower discharge section 3012.

[0056] In this embodiment, preferably, the angle between the generatrix of the lower stirring section 3011 and its central axis is 3°.

[0057] The head of the lower mixing hopper 3 is hinged to the end of the piston rod of the lower telescopic cylinder 10. Specifically, the head of the lower mixing cylinder 301 is fixedly connected to a hinge block 4 305 that is hinged to the end of the piston rod of the lower telescopic cylinder 10.

[0058] The tail of the lower mixing bin 3 is hinged to the round rod 7. Specifically, the lower cylinder cover 302 is fixed with a hinge block 306 that is hinged to the round rod 7.

[0059] An isolation pipe 13 is fitted on the round rod 3 7 between the lower mixing bin 3 and the two columns 2 103. The isolation pipe 13 prevents the lower mixing bin 3 from moving along the axial direction of the round rod 3 7. An isolation pipe 14 is fitted on the round rod 4 8 between the lower telescopic cylinder 10 and the two columns 1 102. The isolation pipe 14 prevents the lower telescopic cylinder 10 from moving along the axial direction of the round rod 4 8.

[0060] The tail section of the lower mixing bin is hinged to the frame. A lower telescopic cylinder is installed between the frame and the head section of the lower mixing bin. The telescopic movement of the lower telescopic cylinder adjusts the tilt angle of the lower mixing bin, thereby changing the discharge speed of the lower mixing bin. The rotation speed of the lower stirring shaft in the lower mixing bin is controlled separately by a lower reduction motor. This allows the mixing speed and discharge speed of the feed in the lower mixing bin to be controlled separately, and the mixing speed and discharge speed of the feed can be adjusted separately according to the needs of feed mixing.
