Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a weeding machine for corn planting. Background Technology

[0002] Corn, as one of my country's important food crops, is widely cultivated throughout the country. Its yield and quality directly affect the development of the agricultural economy and the stability of farmers' income. If weeds are not removed from the fields before corn planting, they will compete with corn for water, nutrients, and sunlight, and may also spread pests and diseases, seriously affecting the normal growth and final yield of corn. Therefore, weeding is a crucial aspect of corn planting management. Currently, common weeding methods in agricultural production mainly include manual weeding, chemical weeding, and mechanical weeding. While manual weeding is highly precise, it is labor-intensive, inefficient, and costly, making it difficult to meet the needs of large-scale modern agriculture. Chemical weeding, although efficient and convenient, easily pollutes the environment and poses potential safety hazards to the soil and crops themselves, and its use has been gradually restricted in recent years. Mechanical weeding, due to its high efficiency and environmental friendliness, has become the main development direction for agricultural weeding at present.

[0003] However, existing mechanical weeding equipment still has many problems. The main problem is that most equipment can only cut weeds and lacks an effective collection device, which causes the cut weeds to be scattered on the ground. This not only affects field hygiene but also makes it easy for weeds to reproduce again and affect subsequent corn planting. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a weeding machine for corn planting, which solves the technical problem that existing mechanical weeding equipment can only cut weeds and lacks an effective collection device, resulting in the cut weeds being scattered on the ground, which not only affects field hygiene but also easily causes weeds to reproduce again and affects subsequent corn planting.

[0005] According to one aspect, at least one embodiment of the present invention provides a weeding machine for corn planting, comprising:

[0006] The vehicle frame has wheels rotatably mounted on both sides of its bottom. Mounting plates are symmetrically fixed to the front end of the vehicle frame. A fuel engine and a reducer are fixed to the top of the vehicle frame. The output end of the fuel engine is fixedly connected to the input end of the reducer.

[0010] For example, in a corn planting weeder provided in at least one embodiment of the present invention, the weeding component includes a mounting shaft, which is rotatably mounted between two mounting plates. Circular plates are symmetrically fixed on both sides of the mounting shaft, and a plurality of inclined blades are uniformly fixed between the outer edges of the two circular plates.

[0011] For example, in a corn planting weeder provided in at least one embodiment of the present invention, a plurality of fan-shaped through slots are provided on the circular plate, and one end of the mounting shaft passes through the mounting plate and is connected to the transmission mechanism.

[0012] For example, in at least one embodiment of the present invention, a weeding machine for corn planting is provided, wherein the transmission mechanism is a belt drive mechanism.

[0013] For example, in at least one embodiment of the present invention, a weeding machine for corn planting is provided, wherein the collecting component includes a collecting box, an inclined feeding trough is provided on the side of the collecting box near the frame, a connecting shell is fixed to the top wall of the collecting box, a drive shaft is rotatably installed between the inner walls of the feeding trough, the drive shaft is driven by an external motor, a plurality of L-shaped rods are symmetrically fixed to the outer wall of the drive shaft, a box door is rotatably installed on the bottom of the rear wall of the collecting box via a hinge, one side of the box door is connected to the rear wall of the collecting box via a pin, and a handle is fixed to the bottom of the box door.

[0014] For example, in a corn planting weeder provided in at least one embodiment of the present invention, the connecting shell is slidably sleeved at the end of the connecting frame, and the side wall of the connecting shell is provided with a pin hole that cooperates with the pin shaft.

[0015] For example, in a corn planting weeder provided in at least one embodiment of the present invention, the side wall of the collection box is provided with several strip-shaped through grooves corresponding to the L-shaped rod.

[0016] The beneficial effects of the embodiments of this utility model are as follows:

[0017] (1) In this utility model, by setting a mowing component at the front of the frame and a collection component at the rear, and combining the belt drive structure to drive the mounting shaft to rotate, the blades can complete efficient cutting while the L-shaped rod smoothly guides the cut weeds to the collection box, which significantly improves the working efficiency and avoids the weed residue affecting the subsequent growth of corn.

[0031] like Figure 1 As shown, it illustrates a weeding machine for corn planting according to one embodiment of the present invention, comprising:

[0032] The frame 1 has wheels 13 rotatably mounted on both sides of the bottom of the frame 1. The front end of the frame 1 is symmetrically fixed with mounting plates 2. The top of the frame 1 is fixed with a fuel engine 4 and a reducer 5. The output end of the fuel engine 4 is fixedly connected to the input end of the reducer 5. The rear end of the frame 1 is fixed with a handle 7 and a connecting frame 8.

[0033] The lawn mowing assembly 3 is rotatably mounted between two mounting plates 2, and the output end of the reducer 5 is connected to the lawn mowing assembly 3 through the transmission mechanism 6.

[0034] Collection component 9 is fixed to the end of the connecting bracket 8 by a pin 10.

[0035] A mudguard 14 is fixed between the tops of the two mounting plates 2.

[0036] Transmission mechanism 6 is a belt drive mechanism.

[0037] In this embodiment, the fuel engine 4 is connected to the reducer 5, which is connected to the mowing assembly 3 via a belt drive mechanism. This allows the mowing assembly 3 to rotate, cutting weeds in the cornfield. The cut weeds are then collected by the collecting assembly 9, preventing weed accumulation from affecting subsequent corn planting. The collecting assembly 9 is mounted on the connecting frame 8 using a pin 10, facilitating its disassembly and installation. The mudguard 14 effectively prevents mud from splashing during mowing, thus avoiding interference with the operator's work. In this embodiment, to facilitate the movement of the entire device and reduce the operator's workload, the wheels 13 can also be driven by an external drive device.

[0038] like Figure 2As shown, it illustrates a lawn mowing assembly 3 in another embodiment of the present invention. The lawn mowing assembly 3 includes a mounting shaft 31, which is rotatably mounted between two mounting plates 2. Circular plates 32 are symmetrically fixed on both sides of the mounting shaft 31, and a plurality of inclined blades 33 are uniformly fixed between the outer edges of the two circular plates 32.

[0039] The circular plate 32 has several fan-shaped through slots, and one end of the mounting shaft 31 passes through the mounting plate 2 and is connected to the transmission mechanism 6.

[0040] In this embodiment, the mowing component 3 is used to cut weeds in the cornfield. When the cutting operation is required, the fuel engine 4 is started. The fuel engine 4 drives the mounting shaft 31 to rotate through the reducer 5 and belt drive mechanism. During the rotation of the mounting shaft 31, the blades 33 on the outside of the circular plate 32 rotate, thereby cutting the weeds. At the same time, a fan-shaped through groove is opened on the circular plate 32, which can effectively reduce the weight of the circular plate 32, reduce the amount of material used, and reduce production costs.

[0041] like Figures 3-4 As shown, the collection component 9 in another embodiment of the present invention is illustrated. The collection component 9 includes a collection box 91. An inclined feeding trough is provided on the side of the collection box 91 near the frame 1. A connecting shell 92 is fixed to the top wall of the collection box 91. A drive shaft 93 is rotatably installed between the inner walls of the feeding trough. The drive shaft 93 is driven by an external motor (not shown in the figure). Several L-shaped rods 94 are symmetrically fixed to the outer wall of the drive shaft 93. A box door 96 is rotatably installed on the bottom of the rear wall of the collection box 91 through a hinge 95. One side of the box door 96 is connected to the rear wall of the collection box 91 through a pin 97. A handle 98 is fixed to the bottom of the box door 96.

[0042] The connecting shell 92 is slidably sleeved on the end of the connecting frame 8, and the side wall of the connecting shell 92 is provided with a pin hole 11 that cooperates with the pin shaft 10.

[0043] The side wall of the collection box 91 has several strip-shaped through slots 12 that pass through the L-shaped rod 94.

[0044] In this embodiment, the collection component 9 can collect the cut weeds, preventing weed accumulation from affecting subsequent corn planting. For example... Figure 3As shown, during use, the external motor drives the drive shaft 93 to rotate. The rotation of the drive shaft 93 causes the L-shaped rod 94 to move clockwise. As the L-shaped rod 94 moves, it scrapes up weeds from the ground. When the L-shaped rod 94 rotates into the collection box 91, the weeds fall into the feed chute of the collection box 91. Because the feed chute is inclined, the weeds fall to the bottom of the collection box 91 under their own weight. When a large amount of weeds accumulates in the collection box 91, the latch 97 can be opened, the handle 98 pulled, and the box door 96 flipped upwards, making it easy to remove the weeds from the collection box 91. The collection component 9 is mounted on the connecting frame 8 using a pin 10, facilitating its disassembly and installation.

[0045] Working Principle: In use, this invention is moved along a cornfield by manual operation or an external power source. During movement, the operator starts the fuel engine 4, which outputs power to the reducer 5. The reducer 5 adjusts the speed appropriately and then transmits the power to the mounting shaft 31 of the mowing assembly 3 via a belt drive mechanism. The mounting shaft 31 rotates under power, causing the circular plates 32 fixed at both ends to rotate. Multiple inclined blades 33 evenly arranged on the outer edge of the circular plates 32 rotate at high speed with the plates, cutting the weeds on the ground. Due to the inclined design of the blades 33, the cutting area and efficiency are enhanced, making it more adaptable. The circular plates 32 have several fan-shaped slots, which effectively reduce the rotating mass, energy consumption, and manufacturing costs while ensuring structural strength. The collection assembly 9, located behind the mowing assembly 3, works synchronously. An external motor drives the drive shaft 93 inside the collection assembly 9 to rotate, and several L-shaped rods 94 are symmetrically mounted on the drive shaft 93. As the drive shaft 93 rotates clockwise, the L-shaped rod 94 moves in a circular motion close to the ground, sweeping the cut weeds upwards and guiding them to the side of the collection box 91 equipped with a feed chute. The feed chute has an inclined structure, allowing the weeds to slide naturally to the bottom of the collection box 91 under gravity, thus achieving centralized collection of the weeds. When the collection box 91 is full of weeds, the operator can pull out the pin 97 to open the box door 96 and empty the weeds inside, completing one work cycle. Simultaneously, the collection component 9 is connected to the connecting frame 8 at the rear of the frame via a pin 10, allowing for easy disassembly or replacement and improving maintenance efficiency. The machine is equipped with wheels and can be optionally equipped with an external power drive system to reduce the burden of manual pushing and improve operational flexibility. A mudguard 14 is installed at the front of the frame 1 to effectively prevent mud and weeds from splashing during the cutting process, ensuring the safety and comfort of the operator. The overall device has a compact structure and is easy to operate, meeting the needs of complex terrain and high-frequency operations in cornfields.

[0046] 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 the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
