Description

Technical Field

[0001] The utility model relates to the technical field of animal husbandry equipment, in particular to a sweeper for cattle and sheep breeding. Background Art

[0002] With the continuous expansion of the scale of animal husbandry and the increasing degree of intensiveness, the cleanliness problem of farms has gradually become prominent and has become an important factor restricting the healthy development of animal husbandry. The traditional manual cleaning method seems to be unable to cope with large-scale farms. Not only is the cleaning efficiency low and consumes a lot of manpower and material resources, but the dust and scattered dirt generated during the cleaning process can easily cause secondary pollution to the breeding environment and even pose a threat to the health of animals.

[0003] Sweepers, as a commonly used cleaning tool in the field of animal husbandry, have long been an important auxiliary to manual propulsion for precise cleaning of designated areas. However, traditional sweepers often expose some problems in actual application. The most prominent of these is that the cleaning of feces and the cleaning of the area need to be carried out separately during the cleaning process, which undoubtedly increases the complexity and time-consuming nature of the cleaning work. Specifically, when cleaning, traditional sweepers usually need to collect the feces manually and then clean the ground. This operating process is not only inefficient and consumes a lot of manpower, but also easily leads to incomplete cleaning and the omission of some imperceptible dirt. In addition, since the cleaning of feces and the cleaning of the ground are two independent steps, it is also easy to cause secondary pollution, which has an adverse effect on the breeding environment.

[0004] Chinese patent document CN213153384U discloses a livestock cleaning vehicle, including a cleaning vehicle body, both sides of which are provided with sealed glass doors, one side of which is provided with a fire storage box, and the lower end of which is provided with a disinfection mechanism; however, the following defects still exist in the implementation process:

[0005] Although the device in the above document enhances the disinfection effect of the main body of the cleaning vehicle by means of the provided disinfection mechanism, thereby reducing the harm of viruses and bacteria to livestock, the device in the above document cannot simultaneously clean the feces and the ground during use. Utility Model Content

[0006] The purpose of the utility model is to provide a sweeper for cattle and sheep breeding to solve the problems raised in the above-mentioned background technology.

[0007] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0009] A further improvement of the technical solution of the utility model is that the manure shoveling structure includes a connecting frame, the lower end of the connecting frame is fixedly connected to the upper end of the water tank, the inner cavity of the connecting frame is slidably connected to a storage structure, and the upper part of the connecting frame away from the handrail is fixedly connected to a manure shovel.

[0010] By adopting the above technical solution, the feces on the ground can be thoroughly cleaned by the feces shovel. No matter whether it is dry feces or wet dirt, the feces shovel can quickly scoop it up, laying a solid foundation for subsequent cleaning work, and then the feces can be stored and collected through the cooperation of the connecting frame and the storage structure.

[0014] The above-mentioned technical solution is adopted, in which the air outlet slot is operated, and the air outlet slot will generate a strong suction force, so that the air in the connecting frame and the inner cavity of the garbage box can be effectively extracted. In this process, the feces, dust and other debris in the inner cavity of the dung shovel will be quickly lifted up and transported to the inner cavity of the garbage box along with the air due to the influence of the airflow generated by the air outlet slot, thereby improving the cleaning efficiency.

Subsequently, when it is necessary to clean the ground, the sweeping structure and the water supply structure are driven by the support plate 2 to descend to an appropriate position. At this time, the sweeping structure and the water supply structure can play their cleaning function and thoroughly clean the ground. Since the contact with the dung has been avoided before, the sweeping structure and the water supply structure can remain efficient and hygienic during the cleaning process.

[0020] The above-mentioned technical scheme is adopted, in which the water in the inner cavity of the water tank is transported to the inner cavity of the water pipe two by means of a water pump through water pipe one and a bellows, and then the water pipe two and the nozzle cooperate to remove dust from the ground, thereby preventing a large amount of dust from being generated when the cleaning brush one cleans the ground, thereby affecting the physical and mental health of the staff. The nozzle can be used to flush the stubborn fecal residue or dust remaining on the ground, thereby facilitating the cleaning of the cleaning brush one.

[0021] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:
