Technical Field

[0001] This utility model belongs to the technical field of stubble removal devices, and in particular relates to a rapeseed greening and returning device. Background Technology

[0002] In agricultural production, rapeseed is an important oilseed and cash crop, with a wide planting area. After the rapeseed flowering period, in order to optimize land use efficiency and create conditions for subsequent planting of ornamental plants or other crops, it is usually necessary to return the rapeseed straw to the field as green mulch. This process not only helps to increase the soil organic matter content and improve soil structure, but also reduces the environmental pollution caused by straw burning, which is in line with the concept of sustainable agricultural development.

[0003] However, current technologies primarily rely on large rotary tillers and stubble removers for the treatment of rapeseed straw mulching and returning it to the field. While these machines are highly efficient, they suffer from drawbacks such as large size, complex operation, high cost, and difficulty in adapting to small plots. Particularly in irregularly divided landscape areas, the access and operation of large machinery are severely restricted, making it difficult to effectively implement rapeseed straw mulching and returning it to the field in these areas.

[0004] In addition, although traditional manual methods of returning fertilizer to the field are flexible, they are labor-intensive, inefficient, and difficult to guarantee the consistency of the quality of returning fertilizer to the field, which cannot meet the production needs of modern large-scale and mechanized agriculture.

[0005] Therefore, in view of the above-mentioned problems in the existing technology, it is particularly important to develop a rapeseed greening and returning device that is compact in structure, easy to operate, easy to move, and can adapt to complex terrain. Utility Model Content

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Specific Implementation Example 1: Please see Figure 1-8As shown, this utility model is a rapeseed green compressing and returning device, including a horizontal base plate 17, a motor 11, a tamping frame 12, a weighted accessory 13, a large pulley 14, a medium pulley 15, a small pulley 16, and a handle 19. A cutting and crushing component is mounted on the lower end of the tamping frame 12 via two rows of first bolt and nut assemblies 1. A row of idler rollers 2 is mounted on the lower surface of the horizontal base plate 17. A backward movement suppression plate 3 is hinged to the end of the horizontal base plate 17 away from the cutting and crushing component via a hinge seat. The idler rollers 2 mounted on the lower surface of the horizontal base plate 17 allow for smooth movement of the device. The backward movement suppression plate 3 effectively prevents the device from moving backward, ensuring stability. Smooth movement reduces the time spent transferring the device in the field and improves overall work efficiency. The motor 11 is mounted in the middle of the horizontal base plate 17 via a motor mounting base 18, and the handle 19 is rotatably mounted on one end of the horizontal base plate 17. The handle 19 and the horizontal base plate 17 can also be fixedly connected; this embodiment uses a rotatable connection, mainly for ease of storage. Two raising blocks 110 are fixed to the upper surface of the other end of the horizontal base plate 17. A first round shaft 112 is mounted on each of the two raising blocks 110 via two first bearing 111. The tamping frame 12 is rotatably mounted on the first round shaft 112. A second round shaft 114 is mounted on the tamping frame 12 via two second bearing 113. A small pulley 16 is mounted on the output shaft of the motor 11. A medium pulley 15 and a small pulley 16 are mounted on the first round shaft 112. The small pulley 16 and the medium pulley 15 on the motor 11 are driven by a first belt 115. A large pulley 14 is mounted on the second round shaft 114. The small pulley 16 and the large pulley 14 on the first round shaft 112 are driven by a second belt 116. Two symmetrically mounted weighted accessories 13 are mounted on the large pulley 14. Two rows of first through holes 121 that mate with the first bolt and nut assembly 1 are provided on the rectangular plate at the lower end of the tamping frame 12.

[0029] The cutting and crushing assembly includes a cutting base plate 4 and a transverse cutting blade 5. The cutting base plate 4 is a rectangular plate structure, with a row of threaded blind holes 41 on the front and rear sides opposite to the handle 19. A transverse cutting blade 5 is mounted on the front and rear sides of the handle 19 via a row of bolts. The cutting base plate 4 has two rows of stepped through holes 42 that mate with the first bolt and nut assembly 1.

[0030] To increase the cutting range and cutting directions of the cutting and crushing assembly, a longitudinal cutting blade 6 is also included. A row of transverse vertical plates 43 is fixed to the lower surface of the cutting base plate 4. A row of second circular through holes 44 is formed on the transverse vertical plates 43. A longitudinal cutting blade 6 is installed on the transverse vertical plates 43 through a row of second bolt and nut assemblies. The combination of the transverse cutting blade 5 and the longitudinal cutting blade 6 enables multi-directional cutting of rapeseed straw. The motor 11 drives the tamping frame 12 to swing, causing the cutting and crushing assembly to quickly press against the straw, ensuring efficient crushing. Fine cutting and crushing increases the contact area between the straw and the soil, accelerates the microbial decomposition process, and facilitates the rapid release of nutrients from the straw into the soil, improving soil fertility.

[0031] Motor 11 drives the large pulley 14 to rotate via two belts. Due to the weighted component 13 mounted on the large pulley 14, the tamping frame 12 oscillates periodically up and down around the first circular shaft 112 under inertia. During the downward swing of the tamping frame 12, the cutting and crushing components rapidly press down on the rapeseed straw below. The transverse cutting blade 5 and the longitudinal cutting blade 6 chop the rapeseed stalks, achieving the crushing and returning of the rapeseed stalks to the field. The crushed straw forms organic matter in the soil, increasing soil porosity, improving soil aeration and water retention, and creating a favorable soil environment for subsequent ornamental plant planting.

[0032] The backward movement suppression plate 3 includes an L-shaped folding plate 31. The upper end of the L-shaped folding plate 31 is hinged to the end of the horizontal seat plate 17 via a hinge seat. The lower end of the L-shaped folding plate 31 is provided with a pointed part 32. A foot pedal 33 is fixed in the middle of the L-shaped folding plate 31. During the process of crushing and returning rapeseed stems to the field, the handle 19 is held to push the entire device forward. A row of idlers 2 installed below the horizontal seat plate 17 facilitates the movement of the equipment. The pointed part 32 at the lower end of the L-shaped folding plate 31 contacts the ground. When the horizontal seat plate 17 moves backward, the pointed part 32 at the lower end of the L-shaped folding plate 31 inserts into the soil to suppress the backward movement of the equipment.
