Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, and in particular to a hemp film cutting machine. Background Technology

[0002] Hemp film seedling raising technology is a novel seedling raising technique. The use of hemp film not only effectively fixes the seedlings, facilitating early transplanting and high yields in machine transplanting, but also produces seedlings with well-developed root systems, abundant white roots, and uniform, robust growth. It also facilitates seedling removal, transportation, and loading, saving labor and costs. However, the hemp film needs to be cut using a cutting machine before it can be used with a rice transplanter. A survey of existing hemp film cutting machines revealed the following problems:

[0003] (1) The cutting size is not adjustable and cannot be matched with different models of rice transplanters;

[0004] (2) The cutting depth is not adjustable, making it impossible to balance effectiveness and energy saving;

[0005] (3) When cutting, do not cut too close to the sides of the seedling shed, as this will waste seedlings;

[0006] (4) The seedling pieces are not of uniform size during reciprocating cutting;

[0007] (5) The equipment is too large, making it inconvenient to turn around and resulting in low work efficiency. Utility Model Content

[0008] The main purpose of this invention is to provide a sisal membrane cutting machine to solve the above-mentioned problems.

[0009] To achieve the above objectives, this utility model provides a muslin membrane cutting machine, including a frame on which a drive mechanism is mounted; a drive wheel is mounted at the bottom of the frame; a handlebar is mounted at the rear end of the frame; a cutting bracket is mounted at the front end of the frame, and a rotating shaft is rotatably mounted within the cutting bracket; multiple adjustable cutting components are spaced apart on the rotating shaft; both ends of the rotating shaft are located outside the ends of the cutting bracket; both ends of the cutting bracket are equipped with a depth-limiting wheel assembly and a scale assembly; the drive mechanism is used to drive the rotating shaft and the drive wheel to rotate.

[0010] Furthermore, a drive axle is provided at the bottom of the vehicle frame, and the drive wheels are mounted on the drive axle.

[0011] Furthermore, the drive mechanism includes an engine and a gearbox; the engine is poweredly connected to the gearbox; the gearbox has two output shafts; the two output shafts are poweredly connected to a rotating shaft and a drive axle, respectively.

[0012] Furthermore, the gearbox is also equipped with a travel control lever and a cutting control lever.
