Description

Technical Field

[0001] The utility model belongs to the field of dairy cow breeding and relates to a grass mixing device in the process of precise feeding of dairy cows. Background Art

[0002] The precise mixing of grass and concentrate for feeding dairy cows is of great significance at different growth stages of dairy cows. It not only improves the digestibility and nutritional value of feed, but also improves the taste and appetite of feed, thereby meeting the nutritional needs of dairy cows at different growth stages.

[0003] However, currently when concentrate and forage are mixed, the forage is not crushed, and the particles of the forage will clump together, which will make it difficult for the digestive juice to fully contact the feed. Utility Model Content

[0004] The purpose of the utility model is to provide a forage mixing device for the precise feeding of dairy cows, which solves the problem that when the concentrate and forage are mixed, the forage is not crushed, the forage particles will agglomerate, which will make it difficult for the digestive fluid to fully contact the feed.

[0005] The technical solutions adopted in this utility model are as follows:

[0006] A grass mixing device for precise feeding of dairy cows comprises a mixing tank with an opening at the top, a mixing paddle provided inside the mixing tank, a motor installed on the top of the mixing paddle, the motor being connected and fixed to the side wall of the mixing tank via a connecting shaft, a horizontally placed first conveyor being provided on one side of the mixing tank, the conveying terminal of the first conveyor being located above the opening at the top of the mixing tank, a double-roll crusher being provided above the conveying initial end of the first conveyor, a discharge port of the double-roll crusher being located above the upper conveying surface of the first conveyor and the material discharged from the double-roll crusher through the discharge port falling onto the upper conveying surface of the first conveyor, and an outer wall of the double-roll crusher being connected and fixed to the frame of the first conveyor.

[0007] The utility model provides a first conveyor on one side of the mixing tank, and then provides a double-roller crusher above the first conveyor. The double-roller crusher is used to crush the grass, and the grass discharged from the double-roller crusher after crushing is conveyed to the mixing tank by the first conveyor to participate in the mixing of the concentrate. This solves the current problem that when the concentrate and grass are mixed, the grass is not crushed, the grass particles will agglomerate, which will make it difficult for the digestive fluid to fully contact the feed.

[0008] Furthermore, a horizontally placed second conveyor is provided on the other side of the mixing tank, and the first conveyor and the second conveyor are arranged opposite to the mixing tank.

[0009] The second conveyor is used to convey the concentrate to the mixing tank, thereby improving the feeding efficiency of the concentrate.

[0010] Furthermore, a vertically placed scraper is provided above the upper conveying surface of the second conveyor. The scraper spans the upper conveying surface of the second conveyor. The top of the scraper side is a rectangular surface, and the bottom of the scraper side is a triangular surface with the tip facing downward. The two side surfaces of the scraper are connected and fixed to the frame of the second conveyor, and there is a distance between the bottom of the scraper and the upper conveying surface of the second conveyor.

[0011] The utility model installs a scraper above the second conveyor, which scrapes the fine material on the upper conveying surface of the second conveyor flat, so that the fine material is evenly distributed on the upper conveying surface of the second conveyor, and the fine material is evenly added into the mixing tank.

[0012] Furthermore, the distance between the bottom of the scraper and the upper conveying surface of the second conveyor is 2 mm.

[0013] Furthermore, the stirring tank is installed on the base, and the base is a U-shaped frame. The stirring tank is placed vertically in the U-shaped groove of the base. The stirring tank and the two side walls of the base are rotatably connected through horizontally placed rotating shafts. The rotating shafts on both sides of the stirring tank are rotatably connected to the two side walls of the base. The stirring tank is fixedly connected to the rotating shafts on both sides. A second motor that drives the rotating shaft on the same side is installed on the side wall on one side of the base, and the rotating shaft of the second motor is fixedly connected to one end of the rotating shaft corresponding to the same side.

[0014] The utility model discloses to facilitate the unloading of the mixing tank, the mixing tank and the base are rotatably connected by a rotating shaft and a second motor. The second motor drives the rotating shaft to rotate, and the rotation of the rotating shaft drives the mixing tank to rotate. During the rotation of the mixing tank, the opening at the top of the mixing tank rotates downward to realize the unloading of the material, replacing manual unloading. The operation is simple and the efficiency is high.

[0015] Furthermore, the rotating shafts on both sides of the mixing tank are rotatably connected to the two side walls of the base through rolling bearings.

[0016] Furthermore, the first conveyor and the second conveyor are both belt conveyors.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0018] 1. The utility model is provided with a first conveyor on one side of the mixing tank, and a roller crusher is provided above the first conveyor. The roller crusher is used to crush the grass. After crushing, the grass discharged from the roller crusher is conveyed by the first conveyor to the mixing tank to be mixed with the concentrate. This solves the problem that when the concentrate and grass are mixed, the grass is not crushed, the grass particles will agglomerate, which makes it difficult for the digestive fluid to fully contact the feed.

[0019] 2. In order to facilitate the unloading of the mixing tank, the utility model connects the mixing tank to the base through the rotating shaft and the second motor. The second motor drives the rotating shaft to rotate, and the rotating shaft drives the mixing tank to rotate. During the rotation of the mixing tank, the opening at the top rotates downward to realize the unloading of the material, replacing manual unloading. The operation is simple and efficient.

[0020] 3. The utility model installs a scraper above the second conveyor, which scrapes the fine material on the upper conveying surface of the second conveyor flat, so that the fine material is evenly distributed on the upper conveying surface of the second conveyor, and the fine material is evenly added into the mixing tank.
