Description

Technical Field

[0001] The utility model relates to the technical field of breeding equipment, in particular to a semi-underground mixing and discharging machine. Background Art

[0002] Feed mixers in animal husbandry usually use a stirring shaft to stir the feed trough. The problem is that the stirring shaft only rotates within a fixed circle and only stirs the material in a part of the trough. Some materials are always unable to enter the stirring area of ​​the stirring shaft, resulting in uneven mixing of the materials. In addition, the existing stirring mechanism generally rotates continuously in one direction and changes the form of the stirring blades on the stirring shaft so that it can contact the material to a greater extent for mixing. It takes a long time to achieve the effect of uniformly stirring the material in the trough.

[0003] In addition, the existing stirring devices are generally placed on the ground, and when adding materials thereto, materials need to be lifted manually or with the aid of a lifting mechanism, which is very inconvenient. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a semi-underground mixing and discharging machine, which is half embedded in the ground. It is not only convenient for adding materials, but also can quickly achieve uniform mixing of materials in the mixing box by setting synchronous reverse staggered mixing discs, thus saving mixing time and ensuring mixing quality.

[0005] The utility model is realized through the following technical solutions:

[0006] A semi-underground material mixing and discharging machine is provided, comprising a material mixing box and a motor box arranged on an outer side wall of the material mixing box, a box body of the material mixing box having a height greater than half thereof is embedded and installed in a groove opened on the ground, an opening for adding grass is arranged on the top surface of the material mixing box, a fine material opening is arranged on one side wall of the material mixing box at a position flush with the ground, two mixing shafts are rotatably installed between two side walls of the material mixing box in the width direction through bearings, each mixing shaft comprises a mixing inner shaft and a mixing outer shaft rotatably sleeved outside the mixing inner shaft and having a cavity, a first mixing disc is installed on the mixing inner shaft, a second mixing disc is installed on the mixing outer shaft, and mixing blades are installed at intervals in the circumference of the two mixing discs;

[0007] A reduction motor and a bidirectional transmission mechanism are installed in the motor box, the driving shaft of the reduction motor is connected to one end of the stirring inner shaft, the bidirectional transmission mechanism includes a U-shaped bracket installed in the motor box, a U-shaped wall on one side of the U-shaped bracket is rotatably connected to the stirring inner shaft, and a U-shaped wall on the other side of the U-shaped bracket is rotatably connected to the stirring outer shaft, the stirring inner shaft is installed with a driving bevel gear in the U-shaped bracket, the stirring outer shaft is installed with a driven bevel gear in the U-shaped bracket, and a transmission bevel gear meshing with both the driving bevel gear and the driven bevel gear is rotatably installed at the U-shaped bottom of the U-shaped bracket.

[0008] Furthermore, a discharge port is provided at the bottom of one side wall of the mixing box, and an inclined spiral conveying auger is connected to the discharge port. The discharge port of the spiral conveying auger is higher than the ground and a material receiving box is provided below the discharge port.

[0009] A discharge port is arranged on one side wall of the mixing box and is connected to a spiral conveying auger. The mixed feed can be discharged from the mixing box through the spiral conveying auger and collected in a receiving box for use.

[0010] Preferably, the first stirring discs and the second stirring discs on the two stirring shafts are arranged alternately in the mixing box.

[0011] The first stirring disc and the second stirring disc on the two stirring shafts are respectively arranged alternately, which can increase the contact area with the material and improve the mixing effect.

[0016] Two stirring shafts are arranged in the mixing box, and each stirring shaft is provided with two stirring disks rotating synchronously in opposite directions. The materials are stirred when the stirring blades installed on the two stirring disks rotate.
