[0017] Figure 3 yes Figure 1 Sectional view along BB;

[0018] As shown in the figure: a stirring tank 1, a main stirring shaft 2, an auxiliary stirring shaft 3, a driving mechanism 4, a cover plate 5, a discharge port 11, an outer spiral stirring belt 21, an inner spiral stirring belt 22, a flexible belt 23, a scraper plate 24, and an auxiliary stirring blade 31. DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1 , Figure 2 As shown, the horizontal feed mixer of the utility model comprises a horizontal stirring tank 1 with an arc-shaped bottom surface and a main stirring shaft 2 arranged in the stirring tank 1, the main stirring shaft 2 is provided with a stirring structure for stirring, and an auxiliary stirring shaft 3 for auxiliary stirring parallel to the main stirring shaft 2 is provided on one side or both sides above the main stirring shaft 2, and the auxiliary stirring shaft 3 is provided with an auxiliary stirring blade 31.

[0021] The areas on both sides above the main stirring shaft 2 specifically refer to Figure 3 The upper left area and the upper right area of ​​the main stirring shaft 2 are shown.

[0022] The working principle of the horizontal feed mixer of the utility model is the same as that of the existing horizontal mixer. When working, the main stirring shaft 2 is driven to rotate by the driving mechanism. During the rotation of the main stirring shaft 2, the stirring structure on it is driven to rotate together, so that the materials in the stirring tank 1 are stirred by the stirring structure to mix the materials. Like the existing horizontal feed mixer, the horizontal feed mixer of the utility model also adopts a horizontal trough structure as a stirring chamber, and there is a large operable space above the stirring shaft, which has the advantages of being convenient for personnel to maintain the stirring shaft in the stirring chamber and clean the stirring chamber. However, the existing horizontal feed mixer will have friction on the material during the rotation of the stirring structure, which will push the material to rotate around the main stirring shaft 2. When the material is transferred out of the stirring tank, there will be a certain amount of scattering due to inertia. In this way, the larger and lighter particles of the material will fall on the surface of the material in the stirring tank 1 during the scattering process, and then it is easy to gather in the two side areas where the stirring structure of the main stirring shaft is not easy to act on. There is a disadvantage that the material in this area is not easy to participate in the mixing, which affects the uniformity of the feed. The horizontal feed mixer of the utility model is provided with an auxiliary stirring shaft 3 for auxiliary stirring parallel to the main stirring shaft 2 in the area on one side or both sides above the main stirring shaft 2, and the auxiliary stirring shaft 3 is provided with an auxiliary stirring blade 31, so that the auxiliary stirring blade 31 of the auxiliary stirring shaft 3 can be used to stir the material in the corresponding area, so that it moves around the auxiliary stirring shaft 3, so that it is easily affected by the stirring structure on the main stirring shaft 2 and participates in the stirring, and then the uniformity of the feed can be further improved. From another aspect, in order to ensure the uniformity of the feed, the traditional horizontal mixer cannot stir too much feed at one time, otherwise the material will gather on both sides above the main stirring shaft 2 and cannot participate in the stirring. After the horizontal feed mixer of the utility model is provided with the above-mentioned auxiliary stirring shaft 3, the mixer can increase the amount that can be stirred at one time under the premise of ensuring the uniformity of the feed.

[0023] During the stirring process, the stirring structure on the main stirring shaft 2 causes the feed to move in the same direction as the main stirring shaft 2. Therefore, most of the materials not involved in the stirring are mainly concentrated on the lower rotating side of the main stirring shaft 2. Considering both production cost and stirring uniformity, the auxiliary stirring shaft 3 is preferably only arranged on the lower rotating side above the main stirring shaft 2. Figure 3 As shown, the main stirring shaft 2 rotates counterclockwise, and the lower rotating side above the main stirring shaft 2 is Figure 3 The upper left side of the .

[0024] like Figure 2 As shown, in the embodiment of the utility model, the auxiliary stirring blade 31 is a spiral blade wound around the auxiliary stirring shaft 3 and extending in the axial direction of the auxiliary stirring shaft 3. In some embodiments, the auxiliary stirring blade 31 is a straight plate or other structure arranged on the auxiliary stirring shaft 3 and extending in the direction of the auxiliary stirring shaft 3.

[0025] The stirring structure can be various plates or protrusions that can produce stirring effects and are arranged on the main stirring shaft 2. In the utility model, the stirring structure includes an outer spiral stirring belt 21 and an inner spiral stirring belt 22 that are wound and fixed on the main stirring shaft 2 and extend along the axial direction of the main stirring shaft 2. There is a spacing between the outer spiral stirring belt 21 and the main stirring shaft 2. The inner spiral stirring belt 22 is arranged on the inner side of the inner edge of the outer spiral stirring belt 21, and there is also a spacing between the inner spiral stirring belt 22 and the main stirring shaft 2. The inner spiral stirring belt 22 has an opposite rotation direction to the outer spiral stirring belt 21. Both the outer spiral stirring belt 21 and the inner spiral stirring belt 22 can be integrated or multiple. In the embodiment of the utility model, there are two outer spiral stirring belts 21 and two inner spiral stirring belts 22. Among them, the distance between the outer spiral stirring belt 21 and the main stirring shaft 2 can be set arbitrarily, and the distance between the inner spiral stirring belt 22 and the main stirring shaft 2 can be determined by experiments to obtain a better value according to the distance between the outer spiral stirring belt 21 and the main stirring shaft 2, the width of the outer spiral stirring belt 21 and the inner spiral stirring belt 22, and the working speed of the main stirring shaft 2. The above-mentioned stirring structure adopts a suspended spiral stirring belt (there is a distance between the inner and outer spiral stirring belts and the main stirring shaft 2), and the outer spiral stirring belt 21 and the inner spiral stirring belt 22 rotate in opposite directions, which will cause the material to tumble in all directions in the stirring tank 1, and its stirring efficiency is higher, the uniformity of the mixed feed is better, and it also saves energy.

[0026] In order to make the crusher discharge cleaner, the utility model also installs a flexible belt 23 on the outer spiral stirring belt 21, the outer edge of which is in contact with the arc-shaped bottom surface of the stirring tank 1. The flexible belt 23 has little wear on the stirring tank, and the provision of the flexible belt 23 is also conducive to further improving the stirring efficiency and uniformity of the feed. The flexible belt 23 can be a rubber belt or a plastic belt.

[0027] The utility model is also provided with a driving mechanism 4, which is drivingly connected to the main stirring shaft 2. The driving mechanism 4 is generally a motor.

[0028] The auxiliary stirring shaft 3 can be driven by a separate driving mechanism, or it can be driven by the same driving mechanism as the main stirring shaft 2. In order to save costs, the auxiliary stirring shaft 3 and the main stirring shaft 2 are preferably driven by a common driving mechanism, that is, the driving mechanism 4 is also connected to the auxiliary stirring shaft 3 through a transmission mechanism. The transmission mechanism can be a belt transmission mechanism, a chain transmission mechanism, etc. In order to further ensure the stirring efficiency and uniformity, the transmission direction of the driving mechanism 4 to the auxiliary stirring shaft 3 is the same as the transmission direction of the driving mechanism 4 to the main stirring shaft 2, and the auxiliary stirring blade 31 is a spiral blade wound around the auxiliary stirring shaft 3 and extending in the axial direction of the auxiliary stirring shaft 3, and the rotation direction of the auxiliary stirring blade 31 is opposite to the rotation direction of the outer spiral stirring belt 21. The transmission direction of the driving mechanism 4 to the auxiliary stirring shaft 3 is the same as the transmission direction of the driving mechanism 4 to the main stirring shaft 2, that is, the driving mechanism 4 drives the auxiliary stirring shaft 3 to rotate in the same direction as the driving mechanism 4 drives the main stirring shaft 2 to rotate. Specifically, when the driving mechanism 4 drives the main stirring shaft 2 to rotate counterclockwise, the driving mechanism 4 drives the auxiliary stirring shaft 3 to rotate counterclockwise; when the driving mechanism 4 drives the main stirring shaft 2 to rotate clockwise, the driving mechanism 4 drives the auxiliary stirring shaft 3 to rotate clockwise. The above structure can push the material in the opposite direction of the outer spiral stirring belt 21 through the auxiliary stirring blade 31, so that the material in the corresponding area of ​​the auxiliary stirring shaft 3 is affected by the outer spiral stirring belt 21, which is conducive to improving the stirring efficiency and stirring uniformity.

[0029] In order to prevent dust from splashing during stirring, the stirring tank 1 is provided with an openable cover plate 5. The cover plate 5 can be connected to the stirring tank 1 in a hinged manner to achieve an openable and closable connection.

[0030] In the utility model, a radial discharge port 11 is provided on one side of the stirring tank 1. To facilitate discharge, a scraper plate 24 is provided on the outer edge of the outer spiral stirring belt 21 along the axial direction of the main stirring shaft 2. The scraper plate 24 can be provided on the main stirring shaft 2 by welding, bolt connection, etc.
