Description

Technical Field

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

[0002] In the process of dairy cattle breeding, grass kneading is an important link, which helps to improve the digestibility and nutritional value of feed. Grass kneading can destroy the plant cell walls and release the cell contents, thereby improving the digestibility of feed by dairy cows. At the same time, the feed after grass kneading is softer and easier for dairy cows to chew and digest, thereby improving the palatability of the feed.

[0003] However, when some existing grass kneading devices use blades to crush grass, the angle of the blade is fixed, and the length of the grass cut by a single blade is fixed, which is not convenient for cutting strips of grass into different sizes. The cutting specifications of materials required by cows of different ages are different. If the degree of cell wall fragmentation of grass is fixed, the grass required by adult cows will not be better absorbed by young cows. In addition, the grass contains moisture. When the blade is crushed, moisture will adhere to its surface and corrode the blade, making it difficult to clean and easily causing rust and damage to the blade. Utility Model Content

[0004] The purpose of the utility model is to provide a grass kneading device for dairy cow breeding to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A grass kneading device for dairy cattle breeding, comprising:

[0007] A grass kneading device, wherein a conveying mechanism is provided inside the grass kneading device;

[0008] A crushing assembly is movably arranged inside the grass kneading device, and the crushing assembly includes a hollow rod movably arranged inside the grass kneading device, and a plurality of connecting seats are fixedly installed on the outer surface of the hollow rod at equal intervals, and a blade is rotatably connected inside the connecting seat;

[0009] The adjusting assembly is movably arranged inside the hollow rod. The adjusting assembly includes supporting rings fixedly installed at both ends of the inner surface of the hollow rod. A pull rod is slidably connected inside the supporting ring.

[0010] Furthermore, a plurality of sleeves are fixedly installed at equal intervals on the outer surface of the pull rod, a T-shaped shift rod is slidably connected inside the sleeve, a plurality of through slots are opened at equal intervals on the outer surface of the hollow rod, and the T-shaped shift rod passes through the through slots and is fixedly connected to the blades at corresponding positions.

[0011] Furthermore, a No. 2 threaded sleeve is symmetrically provided on one side surface of the support ring, and a No. 2 bolt is screwed and connected inside the No. 2 threaded sleeve.

[0012] Furthermore, two kneading rollers are rotatably connected inside the grass kneading device and are located above the conveying mechanism. A No. 1 motor is fixedly installed on one side of the grass kneading device. The output end of the No. 1 motor is fixedly connected to a kneading roller, and the two kneading rollers are connected through a pulley assembly.

[0013] Furthermore, a No. 1 bearing is fixedly embedded on one side surface of the grass kneading device, a collar is fixedly installed on the inner ring of the No. 1 bearing, and the hollow rod is movably connected to the collar.

[0014] Furthermore, a No. 2 bearing is fixedly installed at one end of the outer surface of the hollow rod, a fixing plate movably connected to the grass kneading device is fixedly installed on the outer ring of the No. 2 bearing, a No. 2 motor is fixedly installed on one side surface of the fixing plate, and the output end of the No. 2 motor is fixedly connected to the hollow rod.

[0015] Preferably, the fixing plate and the other side surface of the grass kneading device are both symmetrically fixedly installed with No. 1 threaded sleeves, and two adjacent No. 1 threaded sleeves are screwed and connected with No. 1 bolts.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. By pulling the pull rod, the T-shaped lever is turned inside the through slot, and one end of the T-shaped lever slides inside the sleeve frame, driving the blade to rotate inside the connecting seat and adjusting the cutting angle of the blade. By adjusting the inclination angle of the blade, the length of the forage cut by a single knife can be changed, making it easier to cut strips of forage into different sizes. According to the different forage cutting specifications required by cows of different ages, the degree of forage cell wall fragmentation is changed, making the forage easier for young cows to absorb.

[0018] 2. The No. 2 motor runs, driving the hollow rod to rotate, causing the blade to rotate and crush the grass removed from the conveying mechanism. Twist the No. 1 bolt to separate it from the No. 1 threaded sleeve, pull the fixing plate, disassemble the crushing assembly as a whole, and clean the blade. This makes it easier to disassemble and clean the blade after kneading the grass to prevent moisture in the grass from adhering to the blade surface and corroding the blade, thereby increasing the service life of the blade.

[0019] 3. The grass is transported to the crushing assembly as the conveying mechanism operates. At this time, motor No. 1 operates, driving the kneading roller to rotate. The kneading roller squeezes the grass passing under it, initially destroying its fiber structure, and at the same time squeezes the loose grass into a certain range, making it easier for the crushing assembly to crush it.
