Description

Technical Field

[0001] The utility model relates to the technical field of animal husbandry equipment, in particular to an auger device for a vertical TMR preparation machine. Background Art

[0002] TMR preparation machine, that is, total mixed ration preparation machine, is a device that combines relevant TMR feeding technology to mix multiple materials to obtain a uniformly mixed total mixed ration feed.

[0003] As a key component of the TMR preparation machine, the auger device lifts the materials at the bottom upward during the rotation process, and combines the influence of the material's own gravity to complete the mixing and mixing of various materials. Different auger devices affect the mixing effect and preparation efficiency of the total ration feed. There are many types of auger devices in the existing vertical TMR preparation machines, but there is still the problem of roughage arching caused by unreasonable design of the auger spiral blades, which in turn causes the problem of insufficient utilization of the silo space, reducing the efficiency of total ration preparation. At the same time, there is also the problem of a large amount of residual feed in the silo after discharging, resulting in a waste of the total ration. Summary of the invention

[0004] In order to solve the above problems, the utility model provides a vertical TMR preparation machine auger device to reduce the arching phenomenon and ensure the preparation efficiency of the whole diet. The technical solution adopted by the utility model is as follows:

[0005] A swirling device for a vertical TMR preparation machine comprises a rotating shaft and spiral blades, wherein the spiral blades comprise an upper spiral blade and a lower spiral blade, wherein the outer edge of the upper spiral blade is a spiral of equal diameter, the top end of the lower spiral blade 302 is connected to the bottom end of the upper spiral blade, the outer edge of the lower spiral blade is a spiral whose tangent slope gradually increases downward and the outer diameter of the spiral reaches a maximum at its bottom, and the radial dimension of the outer edge of the lower spiral blade is larger than that of the upper spiral blade.

[0006] The above-mentioned vertical TMR preparation machine auger device has a scraper plate installed at the bottom end of the lower spiral blade.

[0007] The auger device for the vertical TMR preparation machine is provided with a material stripping plate installed at the bottom end of the rotating shaft, and the material stripping plate extends in the radial direction of the rotating shaft.

[0008] In the above-mentioned auger device for the vertical TMR preparation machine, the material-shifting plate is a curved piece, and the direction of its curved protrusion is consistent with the rotation direction of the rotating shaft.

[0009] The beneficial effects of the utility model are as follows: 1) The auger device has upper auger blades with equal spiral outer diameters and lower auger blades with gradually increasing and irregular spiral outer diameters, so that when materials fall onto the auger, no arching occurs, thereby ensuring the lifting effect of the materials and improving the efficiency of preparing the whole diet. The scraper plate can scrape up the materials at the bottom, further reducing the arching phenomenon.

[0010] 2) The auger device uses a material-shifting plate that is convex in the same direction as the auger's rotation. When the auger rotates, the material at the bottom of the spiral auger moves from the center to the surrounding areas along the material-shifting plate. During unloading, less material can be discharged, greatly reducing the residue of the fully mixed ration and avoiding waste. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The technical content of the present utility model is explained in detail below in conjunction with the accompanying drawings.

[0017] The present embodiment is an auger device for a vertical TMR preparation machine, comprising a rotating shaft 2 and a spiral blade 3, wherein a cone cap 1 is screwed onto the top of the rotating shaft 2.

[0018] like Figure 1 and Figure 2 As shown, the spiral blade 3 includes an upper spiral blade 301 and a lower spiral blade 302, the outer edge of the upper spiral blade 301 is a spiral of equal diameter, the top of the lower spiral blade 302 is flush with the bottom of the upper spiral blade 301, the outer edge of the lower spiral blade 302 is a spiral with a gradually increasing tangent slope along the spiral downward, and the outer diameter of the spiral reaches the maximum at the bottom, and the radial size of the outer edge of the lower spiral blade 302 is larger than that of the upper spiral blade 301. This structure not only ensures that the bottom material is lifted, but also solves the problem that the lower spiral blade 302 is too large when the material is dropped, causing the material to form an arch and cannot fall to the bottom of the silo, thereby improving the efficiency of preparing the whole ration.

[0019] like Figure 2 and Figure 3 As shown, a scraper plate 4 is installed at the bottom end of the lower spiral blade 302, and the outer side of the scraper plate 4 is an inclined surface with an inclination angle, so that the bottom material can be conveniently transported upward along the auger blade 3 when the auger rotates.

[0020] A material-diverting plate 5 is installed at the bottom end of the rotating shaft 2. The material-diverting plate 5 extends in the radial direction of the rotating shaft 2. The material-diverting plate 5 and the scraper plate 4 have the same lowest surface. The material-diverting plate 5 and the scraper plate 4 form an angle of 180° at the installation position of the rotating shaft 2. The material-diverting plate 5 is a curved piece, and the direction of its curved protrusion is consistent with the rotation direction of the rotating shaft 2. When the auger rotates together, the bottom material moves from the middle to the surroundings along the protrusion of the material-diverting plate 5, and the mixed full-ration material at the bottom is discharged.
