Description

Technical Field

[0001] The utility model relates to the technical field of dairy cow breeding, in particular to a dairy cow brushing device for dairy cow breeding. Background Art

[0002] In recent years, the dairy cow breeding industry has started to develop rapidly in China. The scale of dairy cow breeding and the milk production continue to increase. However, due to the continuous improvement of the living standards of the people, the demand for high-quality milk and dairy products is also getting higher and higher. Since some dirt such as feces, urine, soil, and old shed hair often adheres to the surface of the cow body, it is easy to breed parasites. Therefore, it is necessary to clean the surface of the cow body to keep the surface of the cow body clean.

[0003] In the prior art, the Chinese utility model patent with the publication number of CN107912324A discloses an automatic cow body brush, which is characterized in that a plurality of rack-shaped splint brushes are axially arranged around the central column to form a cylindrical brush body; a sensor, a controller, a motor and a bracket are installed at the upper end of the central column. It solves the problems of great labor intensity and waste of water source in manual cow body brushing, and is widely applicable to the installation and use in the cowsheds of various livestock farms.

[0004] However, the brush body of this type of automatic cow body brush is vertically and fixedly installed on the crossbeam bracket. The brush body is fixedly installed and cannot swing, resulting in poor cleaning effect. It can only clean the side of the cow, with a small cleaning range and poor adaptability. Content of the Utility Model

[0035] As Figure 1 and Figure 2 shown, a cow brushing device for cow breeding provided by the present utility model includes a bracket 1, a brushing mechanism, and a mounting base 3. The bracket 1 has an inverted L-shaped structure and includes a horizontal part and a hanging part longitudinally arranged at one end of the horizontal part. The other end of the horizontal part is rotatably installed on the mounting base 3 to rotate around a horizontal axis. Among them, the mounting base 3 can be vertically installed on a wall or a column by bolts. The other end of the horizontal part has a coaxial extension connecting shaft 9, and a first bearing seat 10 is provided on the mounting base 3, and the connecting shaft 9 is connected in the first bearing seat 10.

[0036] The brushing mechanism includes a rotary brush, a rotating seat 5, and a reduction motor 6 fixedly installed in the rotating seat 5. The rotating seat 5 is of a U-shaped structure. An installation groove 7 is provided at the bottom of the hanging part. The top ends of both ends of the rotating seat 5 are rotatably installed in the installation groove 7 through a rotating shaft 8, and the rotating shaft 8 is arranged axially perpendicular to the horizontal part. Specifically, second bearing seats 11 are provided on both sides of the installation groove 7, and the rotating shaft 8 is connected in the second bearing seats 11.

[0037] The output shaft of the reduction motor 6 passes downward through the bottom of the rotating seat 5 and is connected to the rotary brush, and the rotary brush hangs on the output shaft of the reduction motor 6.

[0038] Specifically, the rotary brush includes a drum 12 and bristles 13 arranged on the outer wall of the drum 12. The bristles 13 are bundled in clusters and inserted into the outer wall of the drum 12. The bristles 13 are made of nylon material, which has high mechanical strength, a small friction coefficient, and good wear resistance.

[0039] When the rotary brush removes soil, it is necessary to maintain a certain deflection, control the maximum deformation of the bristle end to be less than 13 mm, initially select the bristle length to be 135 mm, and the total diameter of the bristles required to brush off 1 cm 2 of soil clods is 8.5 mm. Then, 8 bristles are distributed within 1 cm 2 on the cylindrical surface.

[0040] In this embodiment, the outer diameter of the rotary brush is 440 mm, the height is 600 mm, and the arrangement height of the bristles 13 is 550 mm; among them, the diameter of the drum 12 is 170 mm, and the length of the bristles 13 is 135 mm.

[0041] Hole punching areas are evenly distributed along the circumference on the outer wall of the drum 12, and the size of the hole punching areas is 9 mm × 9 mm. Each cluster of bristles 13 has 8 bristles, and each cluster of bristles 13 is inserted into the corresponding hole punching area. There are 31 clusters of bristles 13 in one circle. There are 32 circles of hole punching areas. On the same circumference, the center distance between two hole punching areas is 17 mm; the center distance between adjacent two circles of hole punching areas is 17 mm, and the hole punching areas of adjacent two circles are arranged in a staggered manner.

[0042] The dairy cows raised in China are mainly Chinese Holstein cows. The average height of the female cows is 1.35 m, the height of the male cows is 1.40 m, and the body width of the cows is 0.6 m. The height of the rotary brush should adapt to the depth of the cows, and the overall height is 0.6 m. Therefore, as Figure 3As shown in the figure, during installation, the vertical distance h3 between the bottom end surface of the roller brush and the ground is 0.8 m. For the convenience of cows to use and to have sufficient space for use, and to prevent the roller brush from being pushed by cows and touching the wall, resulting in damage, the length dimension L1 of the horizontal part should be greater than 0.88 m. In this embodiment, L1 is designed to be 0.9 m. After calculation, the vertical distance L3 between the bottom surface of the horizontal part and the axis of the rotating shaft 8 is greater than 0.22 m. In order to prevent some cows from being larger in size and causing a larger swing height of the roller brush, L3 should be even larger. In this embodiment, L3 is 0.48 m, L2 is 0.16 m, h1 is 0.78 m, so H is 2.22 m, and the angle Δ of the roller brush swinging from vertical inwards is Δ = 0° - 110°. Figure 3 In this, h2 is the maximum vertical distance from the roller brush to the swing axis when the cow is cleaning its back or head.

[0043] In this embodiment, the working speed of the roller brush is 24 r / min, the power of the reduction motor is 200 W, and the reduction ratio is 60.

[0044] In summary, when the cow approaches the roller brush, under the push of the cow, the roller brush can swing left and right around the axis of the rotating shaft on the rotating seat, and the roller brush, reduction motor and bracket can swing back and forth around the axis of the connecting shaft. The two-way swing enables the roller brush to contact the head, neck, side and back of the cow, with a large cleaning area and strong adaptability.

[0045] Moreover, the brushing device provided by this application determines the structural dimensions of the brushing device through calculation according to the body shape of the cow, which is more suitable for the body shape of the cow and has a better brushing effect.

[0046] Finally, it should be noted that the technical features of the technical solution of this application can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combinations of these technical features do not conflict, they should all be considered to be within the scope recorded in this application.

[0047] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and the description of the present invention.
