Description

Technical Field

[0001] The utility model relates to the technical field of moisture conservation and heat preservation, in particular to a roller sand coating machine for moisture conservation and heat preservation. Background Art

[0002] Moisture conservation is very important in almost every stage of crops, especially in the north. To maintain a certain water content in the soil after sowing the seeds, the soil on the ground should be leveled and fined by raking and grinding. This will reduce the evaporation of water by sunlight and wind, and buy time for the seeds to germinate. After the seeds germinate and their roots move downward, the role of moisture conservation is not too urgent. However, the evaporation of winter wheat in spring and corn after irrigation is very fast.

[0003] Appropriate measures also need to be taken to conserve moisture.

[0004] Most of the sand covering machines on the market cannot achieve the purpose of moisture retention and heat preservation by themselves. This device sets a screen. The staff first turns the connecting rod to open the sealing cover, then aligns the screen with the buckle and installs it into the drum, and then slowly pours the sand and seeds into the drum from the opening. The poured sand is screened by the screen, and the larger sand is caught by the screen. The small sand that is easy to keep warm enters the drum for the next process, which improves the practicality of the device. Most of the sand covering machines on the market use a fixed handle, and the length of the handle cannot be adjusted. It is not suitable for all staff and reduces work efficiency. This device sets a sleeve and a telescopic rod. The staff adjusts the length of the handle according to their own height to facilitate subsequent work, turns the fixing nut counterclockwise, removes the fixing nut from the sleeve and the telescopic rod, and then adjusts the position of the telescopic rod in the sleeve. After adjusting to a length suitable for oneself, put the fixing nut into the threaded hole, and finally turns the fixing nut clockwise to fix it, which improves the work efficiency of the device.
