Description

Technical Field

[0001] This utility model relates to the field of crushing technology, specifically a forage crushing device for cattle breeding. Background Technology

[0002] In livestock production, forage is one of the most important feeds and nutrients. However, forage needs to be crushed before use. Crushing feed raw materials is a very important step in feed processing. Crushing can increase the total surface area of ​​raw material particles per unit mass, increase the solubility of feed nutrients in animal digestive juices, and improve animal digestibility. Therefore, crushing equipment is used to assist in the forage processing.

[0003] For example, the utility model patent application No. 201721212053.5 discloses a forage crusher for beef cattle breeding with high cutting efficiency, including a crushing box. The top of one side outer wall of the crushing box is provided with an opening, and a guide hopper is welded to the inner wall of the opening. The two outer walls of the crushing box are fixed with moving blade rotating shafts by bolts, and the outer walls of the moving blade rotating shafts are fixed with moving blades by bolts. One side outer wall of the crushing box is fixed with a motor by bolts. The two inner walls of the crushing box are both fixed with fixed blades by bolts, and the two inner walls of the crushing box are welded with the same screen.

[0004] Taking the aforementioned forage crusher as an example, there are certain problems in the application of forage crushers. For instance, in order to facilitate feeding, the hopper is designed to be open. However, when crushing forage with high moisture content, some juice splashes into the hopper, increasing the probability of hopper blockage. If dry forage is crushed, the dust generated during the crushing process will escape through the hopper, causing adverse effects on the workers. Summary of the Invention

[0005] The purpose of this invention is to provide a forage crushing device for cattle farming, in order to solve the problems in the prior art where some juice splashes into the hopper when crushing forage with high moisture content, and dust generated during the crushing process of dry forage will escape through the hopper.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a forage crushing device for cattle breeding, comprising a crushing box, a screw conveyor and a feeding hopper, wherein a drive shaft is rotatably connected inside the crushing box, and multiple fan blades, multiple cutting blades and two mounting brackets are fixedly installed on the outside of the drive shaft, and an atomizing nozzle is fixedly connected to the top of the inner cavity of the crushing box, and the atomizing nozzle is connected to a water supply structure.

[0007] Preferably, the feed hopper is fixedly inserted on the outside of the crushing box, and the discharge end of the crushing box is fixedly connected to the feed end of the screw conveyor.

[0008] Preferably, a drive motor and a gearbox are fixedly connected to the top of the crushing box, the output end of the drive motor is fixedly connected to the input end of the gearbox, and the output end of the gearbox is fixedly connected to the top of the transmission shaft.

[0009] Preferably, the multiple fan blades are disposed on the top of the multiple cutting blades, the multiple cutting blades are distributed in two layers, the mounting bracket is disposed at the bottom of the inner cavity of the crushing box, and a rubber pad is fixedly connected to the side of the mounting bracket near the inner wall of the crushing box.

[0010] Preferably, the water supply structure includes a water pump fixedly connected to the top of the pulverizing box and a water storage tank disposed on one side of the screw conveyor. A first guide bend is fixedly connected between the water outlet of the water pump and the atomizing nozzle, and a second guide bend is fixedly connected to the water inlet of the water pump. A connecting pipe is rotatably connected to the bottom end of the second guide bend, and the bottom end of the second guide bend extends into the interior of the water storage tank. The connecting pipe is disposed inside the water storage tank.

[0011] Preferably, a transmission rod is rotatably connected to the bottom of the connecting pipe, and the bottom end of the transmission rod rotatably passes through the bottom of the inner cavity of the water storage tank. A second drive motor is fixedly connected to the bottom of the water storage tank, and the output end of the second drive motor is fixedly connected to the transmission rod. Two fixing plates are fixedly connected to the bottom of the water storage tank.

[0012] Preferably, the top of the transmission rod is provided with a water suction groove, the bottom of the outer side of the transmission rod is provided with multiple guide grooves, and multiple agitator blades are fixedly connected to the outer side of the transmission rod. The multiple guide grooves and multiple agitator blades are all located at the bottom of the inner cavity of the water storage tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. When this application is used, during the rotation of the drive shaft, multiple fan blades draw air from the top of the crushing chamber and blow it downwards at an accelerated speed, so that an airflow from top to bottom is generated inside the crushing chamber. This prevents liquid generated during the crushing of grass with high moisture content from splashing into the feed hopper and prevents dust generated during the crushing of dry grass from escaping through the feed hopper, thereby reducing environmental pollution caused by grass.

[0014] 2. When this application is used, multiple blades with relatively sharp edges first cut the grass. The multiple cutting blades are distributed in two layers, with the upper and lower layers of multiple cutting blades interleaved. The high-speed rotating multiple cutting blades efficiently crush the grass, ensuring the quality of the crushed grass. The rubber pad cleans the bottom of the crushing chamber, stirring and cleaning the crushed grass that falls onto the bottom wall of the crushing chamber, preventing the crushed grass from sticking to the inner wall of the conical space at the bottom of the crushing chamber. The crushed grass processed inside the crushing chamber smoothly enters the feed end of the screw conveyor fixedly connected to the discharge end of the crushing chamber.

[0015] 3. When this application is used, the water pump draws water from the bottom of the water storage tank through the second guide bend, connecting pipe, transmission rod, water suction tank and multiple guide channels. The water pump supplies water to the atomizing nozzle through the first guide bend. The atomizing nozzle atomizes the water and sprays it onto the top of the crushing chamber. The airflow generated by the rotating multiple fan blades transports the water mist downwards, further reducing the generation of dust inside the crushing chamber. Nutrients can also be added inside the water storage tank. During the forage crushing process, the nutrients are evenly mixed into the crushed forage, shortening the forage processing cycle and reducing the cost of forage processing.

A drive shaft 6 is rotatably connected inside the crushing box 1. Multiple fan blades 7, multiple cutting blades 8, and two mounting brackets 9 are fixedly installed on the outside of the drive shaft 6. The multiple fan blades 7 are all located on top of the multiple cutting blades 8, which are distributed in two layers. The mounting brackets 9 are located at the bottom of the inner cavity of the crushing box 1. A rubber pad 10 is fixedly connected to the side of the mounting bracket 9 near the inner wall of the crushing box 1. An atomizing nozzle 11 is fixedly connected to the top of the inner cavity of the crushing box 1, and the atomizing nozzle 11 is connected to a water supply structure.

[0020] Specifically, the feed hopper 3 is fixedly inserted at the top of the outer side of the crushing box 1, feeding grass into the crushing box 1. A drive motor 4 and a gearbox 5 are fixedly connected to the top of the crushing box 1. The output end of the drive motor 4 is fixedly connected to the input end of the gearbox 5, and the drive motor 4 outputs rotational force. The gearbox 5 changes the speed of the rotational force. The output end of the gearbox 5 is fixedly connected to the top of the transmission shaft 6. Multiple fan blades 7, multiple cutting blades 8, and two mounting brackets 9, fixedly connected to the outer side of the transmission shaft 6, rotate. The multiple fan blades 7 are all located on top of the multiple cutting blades 8. The multiple fan blades 7 with relatively sharp edges first cut the grass. The multiple cutting blades 8 are distributed in two layers, with the upper and lower layers of multiple cutting blades 8 interleaved. The multiple cutting blades rotate at high speed... 8. The forage is efficiently crushed to ensure the quality of the crushed forage. The mounting frame 9 is set at the bottom of the inner cavity of the crushing box 1, and a rubber pad 10 is fixedly connected to the side of the mounting frame 9 near the inner wall of the crushing box 1. The rubber pad 10 fits against the inner wall of the conical space at the bottom of the inner cavity of the crushing box 1. The mounting frame 9 drives the rubber pad 10 to rotate, and the rubber pad 10 cleans the bottom of the inner cavity of the crushing box 1, stirring and cleaning the crushed forage that falls onto the bottom wall of the inner cavity of the crushing box 1, so as to prevent the crushed forage from sticking to the inner wall of the conical space at the bottom of the inner cavity of the crushing box 1. The crushed forage processed inside the crushing box 1 smoothly enters the feed end of the screw conveyor 2 fixedly connected to the bottom discharge end of the crushing box 1, and transports the crushed forage into the screw conveyor 2, so as to avoid blockage at the bottom discharge position of the crushing box 1.

[0021] During the rotation of the drive shaft 6, multiple fan blades 7 draw air from the top of the inner cavity of the crushing box 1 and then blow it downwards at an accelerated speed, creating a downward airflow inside the crushing box 1. This prevents liquid generated during the crushing of grass with high moisture content from splashing into the feed hopper 3 and prevents dust generated during the crushing of dry grass from escaping through the feed hopper 3, thereby reducing environmental pollution caused by grass.

[0022] An atomizing nozzle 11 is fixedly connected to the top of the inner cavity of the grinding chamber 1. In the water supply structure, a water pump 13 is fixedly installed on the top of the grinding chamber 1. A guide bend 12 is fixedly connected between the water outlet of the water pump 13 and the atomizing nozzle 11. A connecting pipe 21 is rotatably connected to the bottom of a guide bend 14 fixedly connected to the water inlet of the water pump 13. The bottom of the guide bend 14 extends into the water storage tank 15. A transmission rod 18 is rotatably connected to the bottom of the connecting pipe 21 located inside the water storage tank 15. A water suction groove 22 is opened at the top of the transmission rod 18. Multiple guide grooves 20 opened at the bottom of the outer side of the transmission rod 18 are all connected to the inside of the water suction groove 22. Therefore, the water pump 1... 3.

The water pump 13 supplies water to the atomizing nozzle 11 through the first guide bend 12. The atomizing nozzle 11 atomizes the water and sprays it onto the top of the inner cavity of the crushing box 1. The airflow generated by the rotating multiple fan blades 7 transports the water mist downwards, further reducing the generation of dust inside the crushing box 1. Nutrients can also be added inside the water storage tank 15. During the crushing process, the nutrients are evenly mixed into the crushed forage, shortening the forage processing cycle and reducing the cost of forage processing.

[0023] The bottom end of the transmission rod 18 is rotatably inserted into the bottom of the inner cavity of the water storage tank 15. The output end of the drive motor 17, which is fixedly connected to the bottom of the water storage tank 15, is fixedly connected to the transmission rod 18. The transmission rod 18 is rotatably connected to the connecting pipe 21, so the transmission rod 18 can rotate inside the water storage tank 15. Multiple stirring blades 19 are fixedly connected to the outside of the transmission rod 18. Multiple guide channels 20 and multiple stirring blades 19 are all set at the bottom of the inner cavity of the water storage tank 15. Therefore, by controlling the drive motor 17 to work, the transmission rod 18 rotates, and the multiple stirring blades 19 rotate to stir the water inside the water storage tank 15, so as to prevent the water with added nutrients from settling and ensure that the nutrients in the water are evenly mixed into the forage.

[0024] Two fixing plates 16 are fixedly connected to the bottom of the water storage tank 15 to provide space for the installation of the drive motor 17.
