Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, and in particular relates to a corn stalk rake. Background Technology

[0002] A corn stalk rake is an agricultural machine that gathers stalks scattered in the furrows onto the ridge, and works in conjunction with a corn stalk crusher to improve the stalk breakage rate. Based on the relationship between the direction of the stalks and the direction of the machine's movement, rakes can be divided into two main categories: lateral and cross-sectional.

[0003] Among them, the disc rake is a widely used type of side rake. Most existing disc rakes have relatively simple functions, and the height of the disc relative to the ground is fixed, making it impossible to adjust the vertical height of the disc. This results in low rakeing efficiency when applied to uneven farmland. Utility Model Content

[0004] The purpose of this invention is to provide a corn stalk rake to solve the problem that existing rakes cannot adjust the vertical height of the finger disc. The technical solution adopted by this invention is as follows:

[0005] A corn stalk rake includes a traction frame assembly, longitudinal beams, crossbeams, and finger-disc rake wheels. The rear ends of two longitudinal beams are respectively hinged to the bottom sides of the traction frame assembly. The rear cylinder covers of two lifting cylinders are respectively hinged to the top sides of the traction frame assembly. The piston rods of the two lifting cylinders are respectively hinged to the middle of the two longitudinal beams. Two crossbeams are connected to the front ends of the two longitudinal beams. The two crossbeams are horizontally arranged and symmetrical. The opposite ends of the two crossbeams are inclined backward. Several mounting seats are arranged on the crossbeams. The front ends of several support rods are respectively hinged to the bottom of several mounting seats. The rear ends of the support rods are rotatably equipped with finger-disc rake wheels. The top of the corresponding mounting seat and the middle part of the support rod are respectively hinged to the two ends of a spring shock absorber.

[0006] Furthermore, the traction frame assembly includes a traction mounting plate, swing columns, and ridge width adjusting cylinders. The two swing columns are respectively hinged to the left and right sides of the traction mounting plate via vertically arranged hinge shafts. The rear ends of the two longitudinal beams are respectively hinged to the bottom of the two swing columns. The rear cylinder covers of the two lifting cylinders are respectively hinged to the top of the two swing columns. The ridge width adjusting cylinders are horizontally arranged. The rear cylinder covers of the two ridge width adjusting cylinders are respectively hinged to the traction mounting plate. The piston rods of the two ridge width adjusting cylinders are respectively hinged to the middle of the two swing columns.

[0007] Furthermore, the grass-gathering wheel includes a hub, and the outer circumference of the hub is evenly provided with a number of blade-shaped spokes.

[0008] Furthermore, the mounting base can be detachably mounted on the crossbeam using U-bolts.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] After corn harvesting, a large amount of corn stalks fall into the furrows. This invention, installed in front of a stubble remover, connects a lifting cylinder to the hydraulic system of the remover. The height of the finger-disc rake can be adjusted by extending and retracting the piston rod of the lifting cylinder. When the tillage is too uneven, the height of the finger-disc rake can be lowered. When the finger-disc rake encounters a depression, the spring damper extends; when it encounters a bump, the spring damper compresses, ensuring the finger-disc rake remains in contact with the ground to adapt to uneven terrain. The travel speed of the remover controls the rotation speed of the finger-disc rake, gathering the corn stalks in the furrows onto the ridges. After the remover operates, the amount of long stalks remaining in the furrows is reduced, increasing the stalk breakage rate. Attached Figure Description

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the present utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0015] The connections mentioned in this utility model are divided into fixed connections and detachable connections. Fixed connections, also known as non-detachable connections, include but are not limited to conventional fixed connection methods such as folded connections, riveted connections, adhesive connections, and welded connections. Detachable connections include but are not limited to conventional disassembly methods such as bolt connections, snap-fit ​​connections, pin connections, and hinge connections. When a specific connection method is not explicitly defined, it is assumed that at least one existing connection method can be found to achieve this function, and those skilled in the art can choose according to their needs. For example, a welded connection can be chosen for a fixed connection, and a bolted connection can be chosen for a detachable connection.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0017] Example: Figures 1-2 As shown, a corn stalk rake includes a traction frame assembly, longitudinal beams 5, crossbeams 6, and finger-disc rake wheels 10. The rear ends of the two longitudinal beams 5 are respectively hinged to the bottom sides of the traction frame assembly. The rear cylinder covers of the two lifting cylinders 4 are respectively hinged to the top sides of the traction frame assembly. The piston rods of the two lifting cylinders 4 are respectively hinged to the middle parts of the two longitudinal beams 5. The hinge shafts between the lifting cylinders 4, longitudinal beams 5, and traction frame assembly are all horizontally arranged. The two crossbeams 6 are connected to the front ends of the two longitudinal beams 5 one-to-one. The two crossbeams 6 are horizontally arranged and symmetrical from left to right. The opposite ends of the two crossbeams 6 are inclined backward. A plurality of mounting seats 7 are arranged on the crossbeams 6. The front ends of a plurality of support rods 8 are respectively hinged to the bottom of a plurality of mounting seats 7 one-to-one. The rear ends of the support rods 8 are rotatably equipped with finger-disc rake wheels 10. The top of the corresponding mounting seat 7 and the middle part of the support rod 8 are respectively hinged to the two ends of the spring shock absorber 9.

[0018] After corn harvest, a large amount of corn stalks fall into the furrows. This utility model is installed in front of the stubble destroyer. The lifting cylinder 4 is connected to the hydraulic system of the stubble destroyer. The height of the finger disc rake wheel 10 can be adjusted by extending and retracting the piston rod of the lifting cylinder 4. When the cultivated land is too uneven, the height of the finger disc rake wheel 10 can be lowered. When the finger disc rake wheel 10 encounters a pit, the spring shock absorber 9 extends; when the finger disc rake wheel 10 encounters a bump, the spring shock absorber 9 compresses, so that the finger disc rake wheel 10 can always be in contact with the ground to adapt to the unevenness of the cultivated land. The travel speed of the stubble destroyer controls the rotation speed of the finger disc rake wheel 10, gathering the corn stalks in the furrows to the ridge. After the stubble destroyer operates, the amount of long stalks remaining in the furrows is reduced, and the stalk breakage rate is improved.

[0019] The traction frame assembly includes a traction mounting plate 1, swing columns 3, and ridge width adjusting cylinders 2. Two swing columns 3 are hinged to the left and right sides of the traction mounting plate 1 via vertically arranged hinge shafts. The rear ends of two longitudinal beams 5 are respectively hinged to the bottoms of the two swing columns 3. The rear cylinder covers of two lifting cylinders 4 are respectively hinged to the tops of the two swing columns 3. The ridge width adjusting cylinders 2 are horizontally arranged, with their rear cylinder covers hinged to the traction mounting plate 1. The piston rods of the two ridge width adjusting cylinders 2 are respectively hinged to the middle of the two swing columns 3. The ridge width of crops is set according to the crop variety. Even when planting corn, there are small ridges and large ridges. The ridge spacing of small ridges is generally 60 cm, while the ridge spacing of large ridges can reach 110 cm. Therefore, swinging the two longitudinal beams can adjust the ridge distance of several finger-disc rake wheels 10 to adapt to different ridge widths. When the piston rods of the two ridge width adjusting cylinders 2 extend and retract, the corresponding longitudinal beams 5 can swing left and right.

[0020] The finger-disc grass-gathering wheel 10 includes a hub, and the outer circumference of the hub is evenly provided with a number of blade-shaped spokes.

[0021] Mounting base 7 is detachably mounted on crossbeam 6 using U-bolts. The detachable connection between mounting base 7 and crossbeam 6 allows for adjustment of the number and position of mounting bases 7 according to actual conditions, further optimizing the arrangement of the finger-disc grass-raking wheels 10.

[0022] The above embodiments are merely illustrative examples of the present utility model and do not limit its scope of protection. Those skilled in the art can make partial changes to it, as long as they do not exceed the spirit and essence of the present utility model, they are all within the scope of protection of the present utility model.
