Description

Technical Field

[0001] This utility model relates to a rotary tiller and a green manure pressing mechanism, belonging to the field of agricultural machinery technology. Background Technology

[0002] Green manure planting is an important part of green tobacco production. Every October, large-scale green manure planting begins in tobacco fields in Shibing County. Following this, in March, cooperatives and tobacco farmers will gradually begin green manure compaction. Traditionally, rotary tillers are used for green manure compaction; however, this method suffers from incomplete green manure pulverization and poor compaction results.

[0003] Existing literature (CN108738437A) discloses a green manure compactor adapted for front and rear attachment. This machine includes a suspension assembly, a support assembly, a roller assembly, and a front suspension connection device. A transverse beam is fixed between the two lower ends of the portal frame of the suspension assembly. A connecting plate is located above the center of the transverse beam, and clamping plates are fixed to its two lower ends. The connecting plate and the two clamping plates are arranged in a triangle to match the three-point suspension mechanism at the rear of the tractor. The front suspension device contains two L-shaped attachment plates. The upper parts of the two attachment plates are fixed to a crossbeam plate, with an upward-extending lug that hinges to the lower end of a tie rod. The upper end of the tie rod and the outer ends of the two hook rods are arranged in a triangle to match the connecting plate and the two clamping plates. This machine can directly connect the suspension assembly to the three-point suspension mechanism at the rear of the tractor as needed, or it can be connected to the counterweight at the front of the tractor via the front suspension connection device. However, this device has a relatively complex structure and high cost, making it unsuitable for use with existing small rotary tillers. Utility Model Content

[0026] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0027] Please see Figures 1 to 6 This embodiment describes a rotary tiller and its green manure pressing mechanism, which includes a rotary tiller 1, a hanging frame 2, a roller 3, and a blade 4.

[0028] The rotary tiller 1, as the main body of the device, provides power and support for pulling the green manure pressing mechanism. The roller 3 is rotatably mounted on the bracket 2. Multiple rows of blades 4 are spaced apart and installed circumferentially on the outer side of the roller 3. A cavity 31 is formed inside the roller 3, and an inlet end 34 and a cover 35 installed on the inlet end 34 are provided on the outer side of the roller 3.

[0029] The roller 3 with blades 4 can be attached to the rotary tiller 1 via the mounting bracket 2, roller 3, and blades 4. The rotary tiller 1 drives the roller 3 to rotate, pressing down the green manure during rotation. Simultaneously, the blades 4 cut the green manure stems, improving the green manure compaction effect. Furthermore, different weights of objects, such as sand or water, can be added to the cavity 31 through the inlet end 34 to adjust the weight of the roller 3, thus meeting the compaction needs of different types of green manure.

[0030] For ease of operation, the mounting bracket 2 includes a mounting seat 21 installed at the rear end of the rotary tiller 1, a bracket 22 installed on the mounting seat 21 via a rotating shaft, a top frame 23 installed on the top of the mounting seat 21, and a spring 24 installed between the top frame 23 and the bracket 22. The bracket 22 can swing up and down relative to the mounting seat 21, and the roller 3 can be rotatably installed on the bracket 22. The top frame 23 is located above the bracket 22, so that the roller 3 can swing with the undulation of the field, while the spring 24 provides a certain downward pressure to ensure its cutting effect.

[0031] To improve efficiency, partitions 32 are spaced along the circumference of the roller 3 within the cavity 31, dividing the cavity 31 into multiple compartments 33. Each compartment 33 has an inlet end 34 and a cover 35, allowing each compartment 33 to hold sand, water, etc., thus achieving overall weight adjustment of the roller 3. Furthermore, when the cavity 31 is not filled with sand or water, the partitions 32 ensure that the weight is evenly distributed throughout the roller 3.

[0032] To facilitate material discharge, the inlet end 34 is located at the end of the roller 3, and a conical hole is provided at the end of the inlet end 34 corresponding to the cavity 31, with the larger end of the conical hole located near the cavity 31, so that the sand and gravel inside the roller 3 can be completely discharged.

[0033] For ease of maintenance, a mounting base 36 is provided on the roller 3. This mounting base 36 has a mounting groove 37, which can be a convex groove. The blade 4 includes a blade body 41 and a blade holder 42 disposed at the bottom of the blade body 41. The blade holder 42 is slidably mounted in the mounting groove 37 and fixed to the mounting base 36 by screws or other fasteners, so that each blade 4 can be replaced as needed. After the cutting is completed, the blade 4 can be removed and placed away.

[0034] To improve the cutting effect, each row of blades 4 consists of multiple blades 4 spaced apart, and the positions of the blades 4 in adjacent rows of blades 4 are staggered. With the blades 4 spaced apart and staggered, the green manure can be cut more evenly when the roller 3 rolls.

[0035] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
