Description

Technical Field

[0001] The utility model belongs to the technical field related to ground film covering, in particular to a ground film covering device. Background Art

[0002] The emergence of agricultural mulch has brought many benefits to agricultural planting, especially in arid areas. The use of mulch can increase soil temperature, retain water and soil moisture, promote crop growth, and ensure a good harvest. The emergence of mulch film machines has solved the problem of time-consuming and labor-intensive manual mulch film laying for farmers, liberating labor. In order to prevent the mulch film from being blown away by strong winds, it is generally necessary to cover the mulch film with soil after laying it, usually in piles or strips at intervals.

[0003] However, the existing mulch covering machine covers soil at a fixed distance when in use, and cannot achieve variable distance covering. Therefore, the mulch covering machine cannot meet the needs of crops with different spacings. Some mulch covering machines have too small covering spacings, which will affect sunlight exposure and thus affect the rise in ground temperature. Too large covering spacings may cause the mulch to be blown away by strong winds, causing losses to farmers. At the same time, when using the mulch covering machine, the soil cannot be dug quickly, which will affect the covering efficiency. To this end, we provide a mulch covering machine to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a mulch covering device, which can increase the rotational circumference of the rim and the covering cylinder and the covering distance by adjusting the distance between the wheel blades and the rim, and at the same time, the soil can be quickly dug out by the coordinated use of the digging shovel and the sliding trough plate.

[0005] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0006] The utility model is a mulch covering device, comprising a covering cylinder; the left and right end surfaces of the covering cylinder are both provided with sliding openings connected with the interior thereof; a main shaft rod passing through the sliding opening is arranged inside the covering cylinder; rims are arranged at the ends of the main shaft rod located on the left and right sides of the covering cylinder; a plurality of wheel blades uniformly arranged in an annular shape are arranged at the periphery of the outer periphery of the rims; a plurality of progressive bolts corresponding to the wheel blades are arranged inside the rims; a large arm is rotatably sleeved on the main shaft rod located between the covering cylinder and the rims; three digging shovels uniformly arranged in an annular shape are arranged on the circumferential side of the main shaft rod between the large arm and the covering cylinder; a mounting cylinder rotatably connected to the main shaft rod through a bearing is arranged at a concentric position between the three adjacent digging shovels.

[0007] The utility model is further configured such that fixed angle codes rotatably connected to the progressive bolts are fixed at positions on the inner side walls of the rim and the wheel blades corresponding to the progressive bolts, nuts spirally connected to the progressive bolts are provided on the inner and outer side surfaces of the rim, and a hub fixedly connected to the main shaft is fixed at the inner axis of the rim.

[0010] The utility model is further configured that a soil sliding trough plate is arranged at a position between the soil covering cylinder and the installation cylinder, and the soil sliding trough plate is fixed at a port position of the soil covering cylinder.

[0011] The utility model is further configured that a sprocket wheel one is fixed on the main shaft rod between the upper arm and the rim, a sprocket wheel two is arranged on the upper arm surface on the same side as the sprocket wheel one, and the sprocket wheel one is connected with the adjacent sprocket wheel two through a chain transmission.
