Description

Technical Field

[0001] The utility model belongs to the technical field of mixers, in particular to a straw mixer. Background Art

[0002] Straw is a general term for the stems and leaves (ears) of mature crops, usually referring to the remaining part of wheat, rice, corn, potatoes, rapeseed, cotton, sugarcane and other crops (usually coarse grains) after the seeds are harvested. It is a multi-purpose renewable biological resource and also a roughage. When feeding straw feed to livestock, the straw feed needs to be crushed and stirred before fermentation to facilitate the livestock to eat the straw feed better. A straw feed stirring device is required to stir the straw feed. In existing feed stirring devices, there are often gaps between the stirring blades. Since the straw needs to be crushed into a relatively slender shape during stirring, the gaps between the stirring blades often lead to uneven straw stirring. Utility Model Content

[0003] In view of this, the purpose of this utility model is to overcome the deficiencies in the prior art and provide a straw feed mixer. This application provides the following technical solutions:

[0004] It includes a mixing bin with an upper opening, a roller is installed on a bearing in the mixing bin, and mixing blades are spirally distributed on the roller; the mixing blades include a connecting rod fixedly connected to the roller and a fan-shaped shovel fixed on the connecting rod; the fan-shaped shovel is arranged at an angle, and when the fan-shaped shovel rotates, the outer edge forms a cylindrical surface, and the cylindrical surfaces formed by the rotation of adjacent fan-shaped shovels are connected in sequence end to end; when the fan-shaped shovel rotates to shovel and flip the straw for stirring, the stirring range has no gaps, ensuring that the straw is fully stirred.

[0005] It also includes a drive motor and a gear transmission. The drive motor is connected to the gear transmission, and the gear transmission is connected to the roller. The drive motor drives the roller to rotate through the gear transmission. The gear transmission is set to change the speed and torque.

[0006] It also includes a frame, and the mixing bin, the driving motor and the gear transmission are all fixedly installed on the frame to facilitate the movement and transportation of the whole.

[0007] A liquid spraying pipe is provided on the upper part of the mixing bin, and a plurality of liquid spraying heads are provided below the liquid spraying pipe, so as to facilitate spraying water to increase the humidity of the straw and apply the straw fermentation agent during mixing.

[0008] An arc-shaped convex plate is provided above the inner side wall of the mixing bin where the roller is not installed; when the upper opening of the mixing bin is opened for feeding, the upper part of the arc-shaped convex plate guides the fed straw, so that the feeding is closer to the center, which facilitates the mixing of the straw. When the straw mixing speed is faster, the lower part of the arc-shaped convex plate prevents the straw from being thrown out along the side wall of the mixing bin.

[0009] The edge of the arc-shaped convex plate is sealed and connected to the inner side wall of the mixing chamber to form a cavity. The spray pipe passes through the side wall of the mixing chamber and is arranged in the cavity. The bottom of the arc-shaped convex plate is provided with multiple through holes corresponding to the spray heads. Hiding the spray pipe in the arc-shaped convex plate makes the structure more compact and prevents straw from hanging on the spray pipe when feeding.

[0010] A reinforcing rib is further provided between the connecting rod and the rotating roller to enhance the bearing strength of the connecting rod and prevent it from being damaged.

[0011] A discharge port is provided at the bottom of the mixing bin, and a discharge plate which can slide and seal the discharge port is provided on the discharge port for discharging materials.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0013] The cylindrical surfaces formed by tilting the fan-shaped shovel to its outer edge and rotating are connected end to end in sequence, so that the stirring range of the fan-shaped shovel is gapless, and the straw is stirred more fully; at the same time, the arc-shaped convex plate is designed to facilitate feeding and prevent the straw from being thrown out, and a liquid spray pipe is set in the arc-shaped convex plate to facilitate the application of liquid when stirring the straw.

[0014] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, preferred embodiments are given below and described in detail with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0025] Please refer to Figure 1-5 As shown, a straw feed mixer provided by the utility model includes a mixing chamber 1 with an upper opening, a roller 2 is installed on a bearing in the mixing chamber 1, and mixing blades 3 are spirally distributed on the roller 2; the mixing blades 3 include a connecting rod 31 fixedly connected to the roller 2 and a fan-shaped shovel 32 fixed on the connecting rod 31; the fan-shaped shovel 32 is arranged at an angle, and when the fan-shaped shovel 32 rotates, the outer edge forms a cylindrical surface, and the cylindrical surfaces formed by the rotation of adjacent fan-shaped shovels 32 are connected end to end in sequence.

[0026] like Figure 3 As shown, in order to achieve the effect of gapless shoveling range when the sector shovel 32 rotates, the axial direction of the roller 2 is used as the coordinate axis, and the projections of the outer edge lines of adjacent sector shovels 32 on the coordinate axis are connected in sequence.

[0027] In addition, the stirring blades 3 on the roller 2 are divided into two parts from the middle, one part of the stirring blades 3 is distributed along a clockwise spiral, and the other part of the stirring blades 3 is distributed along a counterclockwise spiral, and the inclination direction of the fan-shaped shovel 32 is tangent to its corresponding spiral, so that when the fan-shaped shovel 32 rotates, the straw is shoveled towards the middle.

[0028] It also includes a drive motor 4 and a gear transmission 5. The drive motor 4 is connected to the gear transmission 5, and the gear transmission 5 is connected to the roller 2. The drive motor 4 drives the roller 2 to rotate through the gear transmission 5.
