Problems solved by technology

[0005] In view of the fact that most of the farmland wastes in the prior art are large-scale devices, they are not suitable for moving to the farmland site, which brings inconvenience in use, and when the agricultural wastes contain soil, it is easy to cause the waste crushing device to jam, and when there are stones, The problem of harm to the rotating knife

Embodiment 1

[0035] Such as image 3 As shown, the flexible matrix 41 of the flexible knife is in the shape of a triangular knife, and the rigid blade 42 is in a serrated shape, which is inlaid on the surface of the flexible knife. The serrated teeth on the surface of the flexible knife described in this embodiment have high hardness and strong cutting force, suitable Cutting of small materials.

Embodiment 2

[0037] Such as Figure 4 As shown, the flexible base 41 of the flexible knife is in the shape of a triangular knife, and the rigid blade 42 is a steel thorn structure, penetrating through the flexible base. When the waste fiber is long, it is easy to wind the rotor and cause the machine to crash. The long needle structure can wind the waste fiber, and the waste fiber is shredded and broken during the rotation process to realize cutting and crushing.

[0038] Concretely, multiple flexible knives 4 can be used in combination, as the fiber is usually longer when feeding, the cutter described in embodiment 2 can be used, when the fiber is shorter and the particles are finer under the body, the cutter described in embodiment 1 can be used of knives.

[0039] Further, the grinding pattern 21 on the inner wall of the body 2 is a plurality of protrusions, each protrusion runs through the vertical direction of the body, and the protrusions can further improve the grinding effect.

Embodiment 3

[0057] This embodiment provides a method for fertilizing waste on farmland. The method is carried out in the flexible rotor cutter shredder for fertilizing waste on farmland described in Example 1, including the following steps:

[0058] The waste is fed from the feed port above the machine body, and the waste is crushed by the flexible rotor cutter, unloaded during the crushing process, and discharged from the bottom discharge port.

[0059] The waste is continuously fed, and the fertilizer is continuously discharged.

Abstract

The invention belongs to the field of agricultural machinery, and particularly provides a flexible rotor cutter crusher for preparing a fertilizer from farmland field wastes and a use method. The flexible rotor cutter crusher comprises a machine body and a power device, wherein a driving mechanism and a rotor driven by the driving mechanism are arranged in the power device, the rotor is vertical in the center of the interior of the machine body, flexible cutters are connected to the rotor through connecting pieces, and the flexible cutter is structurally characterized in that a rigid blade is fixed to the surface of a flexible base body; the rotor drives the flexible cutters to rotate circumferentially in the horizontal direction to achieve the crushing function, and the machine body is fixed relative to the ground; grinding patterns are formed in the inner wall of the machine body; and a feeding opening of the machine body is formed above, and a discharging opening is formed in the bottom. The problems that in the prior art, most of farmland waste is a large device and is not suitable for being moved to a farmland site, use inconvenience is caused, when the agricultural waste carries soil, a waste crushing device is prone to being clamped, and when the agricultural waste carries pebbles, a rotating cutter is damaged are solved.

Description

technical field [0001] The disclosure belongs to the field of agricultural machinery, and specifically provides a flexible rotor cutter shredder for fertilizing farmland on-site waste and a use method thereof. Background technique [0002] The statements herein merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] With the advancement of agricultural production technology, various agricultural machinery and equipment have begun to be widely used in the field. Due to the needs of agricultural environmental protection, treatment devices suitable for various agricultural wastes have appeared in the prior art. Among them, the agricultural wastes are made into The common application of agricultural waste when making fertilizer is that the waste should be pulverized first in the process of making fertilizer from agricultural waste, and various agricultural waste pulverization devices are also provided in the ...
