Description

Technical Field

[0001] This utility model relates to agricultural machinery, and in particular to a green manure pressing device. Background Technology

[0002] Green manure compaction is an agricultural soil management practice that improves soil structure and fertility by directly incorporating or covering green plant matter (green manure) into the soil. The core of this technique lies in utilizing the biomass of green manure crops to convert it into soil organic matter, thereby increasing soil fertility and improving soil physical properties. Green manure compaction can only be performed using rotary tillage, which cannot break up the green manure crops, resulting in slow decomposition and poor fertilizer efficiency. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a green manure compaction device to solve the technical problem that rotary tillage cannot chop green manure crops when used for green manure compaction.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A green manure pressing device includes a main shaft that is connected to the output end of a rotary tiller. Multiple blade holders are spaced along the length of the main shaft, and multiple tilling blades are radially arranged on each blade holder centered on the main shaft. The device also includes multiple elongated green manure crop chopping blades arranged along the length of the main shaft. These green manure crop chopping blades are spaced apart on the outside of the multiple blade holders and circumferentially along the main shaft. The green manure crop chopping blades are connected to the blade holders via connectors, and the blades of the green manure crop chopping blades face away from the main shaft.

[0006] Furthermore, the green manure crop chopper is connected to multiple blade holders via multiple connectors.

[0007] Furthermore, the green manure crop chopper is composed of long strip-shaped cutting blocks and long strip-shaped mounting blocks connected vertically, and the cutting blocks are connected to multiple blade holders through multiple connectors.

[0008] Furthermore, the connector is an L-shaped rod, with one end of the L-shaped rod connected to the cutting block along the width direction of the cutting block and the other end connected to the blade holder.

[0009] The beneficial effects of this utility model are:

[0010] This utility model discloses a green manure compaction device. The transmission mechanism of the rotary tiller drives the main shaft to rotate, which in turn drives multiple blade holders to rotate, which in turn drives each soil-turning blade and multiple green manure crop chopping blades to rotate. During the rotation, the green manure crop chopping blades chop the green manure crops, and the soil-turning blades plow the soil and compact the chopped green manure crops into the soil. The chopped green manure crops decompose quickly in the soil, resulting in good fertilizer effect.

[0011] The green manure crop chopper is connected to multiple blade holders via multiple connectors, ensuring the installation strength of the green manure crop chopper.

[0012] The connector is an L-shaped rod, which further ensures the installation strength of the green manure crop chopper.

[0013] Other advantages, objectives, and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination and study, or may be learned from practice of this invention. The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

[0020] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0021] like Figure 1-4As shown, a green manure compaction device includes a main shaft 1, which is connected to the output end of the transmission mechanism of a rotary tiller. Multiple blade holders 2 are evenly spaced along the length of the main shaft 1. Each blade holder 2 is an equilateral triangular block, and a tilling blade 3 is connected to each corner of the equilateral triangular block by screws. The tilling blade 3 is a rotary tilling blade, with the section of the rotary tilling blade near the equilateral triangular block parallel to one side of the adjacent equilateral triangular block. It also includes three long, strip-shaped green manure crop chopping blades 4, all arranged along the length of the main shaft 1. The three green manure crop chopping blades 4 are located on the outer side of the multiple equilateral triangular blocks, respectively at each corner of the equilateral triangular blocks. That is, the three green manure crop chopping blades 4 are positioned close to the three rotary tilling blades on the equilateral triangular blocks, with the green manure crop chopping blades 4 located on the inner side of the bending direction of the rotary tilling blades. The green manure crop chopper 4 is composed of a long, rectangular cutting block and a long, rectangular mounting block connected vertically. The cutting edge 5 of the cutting block faces away from the main shaft 1, and the mounting block extends towards the side of the cutting block away from the rotary tiller blade. The cutting block of the green manure crop chopper 4 is connected to multiple blade holders 2 via multiple connectors 6. The connector 6 is an L-shaped rod, with one end connected to the cutting block along its width and the other end connected to the blade holder 2 via screws.

[0022] During the green manure compaction process, the rotary tiller's transmission mechanism drives the main shaft 1 to rotate. The rotation of the main shaft 1 drives multiple blade holders 2 to rotate, which in turn drives various turning blades 3 and multiple green manure crop chopping blades 4 to rotate. The green manure crop chopping blades 4 chop the green manure crops during rotation, while the turning blades 3 turn over the soil and compact the chopped green manure crops into the soil. This device achieves the purpose of green manure compaction by simultaneously turning over the land and chopping and compacting the green manure. The chopped green manure crops decompose quickly in the soil, resulting in good fertilizer effect.

[0023] Of course, the shape of the blade holder 2 can also be a round block, a hexagonal block, etc. The number of rotary tillers and green manure crop chopping blades 4 can be four, five, six, etc.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
