Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, and in particular to a multi-functional high-speed harrow. Background Technology

[0002] The high-speed harrow is a highly efficient agricultural machine used for land preparation. It primarily uses high-speed rotating blades to break up, mix, level, and prepare the soil for seedbeds, making it suitable for land treatment before sowing. Its core functions include stubble removal, stubble mixing, and soil loosening followed by harrowing to create a loose and well-aerated seedbed environment for subsequent sowing.

[0003] However, in the rapid development of modern agriculture, sowing and fertilization, as core links that determine crop yield and quality, are evolving towards more efficient and intensive operations. Nevertheless, the current mainstream field operation model remains the traditional "step-by-step" operation, where key processes such as fertilization, harrowing, sowing, and compaction require multiple entries of agricultural machinery with different functions into the field.

[0004] However, this operating mode involves cumbersome procedures. The repeated entry of agricultural machinery into the field not only severely compacts the soil and damages its original granular structure and aeration, but also leads to long operating cycles, high fuel consumption and labor costs, which runs counter to the goal of high efficiency and low cost pursued by modern agriculture.

[0005] Therefore, in order to comprehensively improve operational efficiency, we propose a multi-functional high-speed harrow. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies, such as the inability to perform simultaneous fertilization, harrowing, sowing, and compaction, and to propose a multi-functional high-speed harrow.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] Design a multi-functional high-speed harrow, including a frame and a hopper mounted on the frame, a front harrow assembly and a rear harrow assembly mounted below the frame, and a seeding assembly disposed between the hopper and the rear harrow assembly;

[0009] The frame has two swing arms rotatably connected to its rear side, and a pressure roller is rotatably connected between the two swing arms. A drive unit for rotating the swing arms is provided on the side of the frame.

[0010] Furthermore, the front rake assembly and the rear rake assembly have the same structure;

[0011] The front rake assembly includes several support plates fixedly installed below the frame, with a bushing fixedly installed at the tail end of the support plate, and a rake disc rotatably connected to the side of the bushing.

[0012] Furthermore, the seeding assembly includes a lever rotatably connected inside the hopper, and a plurality of discharge ports are provided on the end face of the hopper. A seeding bin is fixedly installed on the outside of the hopper at the discharge ports.

[0013] The seeding chamber is rotatably connected to a material distribution plate, which is directly opposite the discharge port. A drive shaft is fixedly connected between several material distribution plates.

[0014] Furthermore, a fixing rod is fixedly installed on the side of the support plate, and the front end of the fixing rod is detachably connected to a seeding pipe through a sleeve. The seeding pipe and the seeding chamber are connected by a pipe.

[0015] Furthermore, a first sprocket is fixedly mounted on the shaft end of the pressure roller, and a second sprocket is fixedly mounted on the shaft end of the drive shaft. The first sprocket and the second sprocket are driven by a chain, and the drive shaft is connected to the shaft end of the actuating rod through a transmission structure.

[0016] Furthermore, the sleeve and the seeding tube are fixedly connected, a spring plug is embedded on the outside of the fixed rod, and a limiting hole adapted to the telescopic end of the spring plug is opened on the outside of the sleeve.

[0017] This invention presents a multi-functional high-speed harrow, which offers the following advantages: The sowing component enables seed and fertilizer application, and the cleverly integrated front and rear harrowing components work synergistically to perform efficient and deep harrowing of the soil. Furthermore, the added pressure roller effectively compacts and breaks up the loosened soil, thus completing multiple processes such as sowing, harrowing, and compaction in one operation, significantly improving operational efficiency and meeting the complex needs of modern agriculture.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-5 In one embodiment of this utility model, a multi-functional high-speed harrow is disclosed. Specifically, the high-speed harrow includes a frame 1 and a hopper 2 installed on the frame 1. The hopper 2 is used to fill seeds and fertilizers. Specifically, in this embodiment, the hopper 2 should have an inclined guide plate inside. The guide plate is designed to tilt and feed the seeds and fertilizers toward one side of the sowing component 5. A front harrow component 3 and a rear harrow component 4 are installed below the frame 1. The sowing component 5 is arranged between the hopper 2 and the rear harrow component 4.

[0026] The frame 1 has two swing arms 6 rotatably connected to its rear side, and a pressure roller 7 is rotatably connected between the two swing arms 6. The side of the frame 1 is provided with a drive member 8 that drives the swing arms 6 to rotate.

[0027] In other words, this invention utilizes the sowing component 5 to achieve seed and fertilizer sowing and application, and cleverly incorporates the front harrow component 3 and the rear harrow component 4, which work together to perform efficient and deep harrowing of the soil. Furthermore, the added pressure roller 7 effectively compacts and breaks up the loosened soil, thus completing multiple processes such as sowing, harrowing, and compaction in one operation, significantly improving operational efficiency and meeting the complex needs of modern agriculture.

[0028] In some embodiments, the front harrow assembly 3 and the rear harrow assembly 4 of this utility model have the same structure. Of course, in this embodiment, the front harrow assembly 3 and the rear harrow assembly 4 are arranged at intervals.

[0029] The front rake assembly 3 includes several support plates 31 fixedly installed below the frame 1. A bushing 32 is fixedly installed at the tail end of the support plate 31, and a rake disc 33 is rotatably connected to the side of the bushing 32.

[0030] Specifically, in this embodiment, the support plate 31 has an L-shaped structure, the harrow disc 33 is rotatably connected to the bushing 32 via a shaft, and several support plates 31 are spaced apart to achieve harrowing operations on the soil.

[0031] Based on the above embodiments, the sowing component 5 in this embodiment includes a lever 51 rotatably connected inside the hopper 2. The lever 51 can be configured as an auger rod. When it rotates, it drives the seeds and fertilizer to move, thereby improving the feeding efficiency. Several discharge ports 21 are opened on the end face of the hopper 2. A sowing bin 52 is fixedly installed on the outside of the hopper 2 at the discharge ports 21.

[0032] The seeding chamber 52 is rotatably connected to a distribution plate 53. The outer circumference of the distribution plate 53 is distributed with several grooves. Through the design of several grooves, when the distribution plate 53 rotates, the seeds and fertilizers discharged from the discharge port 21 can be continuously sent out. The distribution plate 53 is directly opposite the discharge port 21. A drive shaft 54 ​​is fixedly connected between several distribution plates 53.

[0033] Specifically, in this invention, a distribution plate 53 is rotatably installed inside the seeding chamber 52. When the drive shaft 54 ​​rotates, it drives multiple distribution plates 53 to rotate synchronously. At the same time, the internal actuating rod 51 also rotates. When the actuating rod 51 moves the seeds and fertilizer, the seeds and fertilizer will enter the groove of the distribution plate 53 along the discharge port 21. Meanwhile, the distribution plate 53 rotates continuously to continuously send the seeds and fertilizer outward.

[0034] It should be specifically noted that, in this embodiment, a fixing rod 55 is fixedly installed on the side of the support plate 31, and the front end of the fixing rod 55 is detachably connected to the seeding pipe 57 through the sleeve 56. The seeding pipe 57 and the seeding chamber 52 are connected through the pipe 58.

[0035] When seeds and fertilizers are being sent out, they will enter the interior of the seeding pipe 57 along the pipe 58, and then fall onto the ground in sequence to complete the seeding operation. Of course, in this embodiment, the pipe 58 is preferably set as a flexible hose to improve the ease of installation.

[0036] Furthermore, in order to achieve rotational drive of the drive shaft 54 ​​and the actuating lever 51, in this embodiment, a first sprocket 71 is fixedly installed on the shaft end of the pressure roller 7, and a second sprocket 59 is fixedly installed on the shaft end of the drive shaft 54. The first sprocket 71 and the second sprocket 59 are driven by a chain, and the drive shaft 54 ​​is connected to the shaft end of the actuating lever 51 through a transmission structure.

[0037] Specifically, in this embodiment, the swing arm 6 and the drive shaft 54 ​​are coaxially connected and rotate. The drive component 8 can preferably be configured as a hydraulic cylinder, which is pinned to the side of the frame 1 and its shaft end is rotatably connected to the swing arm 6.

[0038] Furthermore, the transmission structure described in this embodiment can be configured as a sprocket and chain assembly structure, and in other embodiments it can also be configured as a pulley and timing belt assembly structure. Those skilled in the art can design according to their actual needs, and will not elaborate further here.

[0039] When the pressure roller 7 rotates while in contact with the ground, its shaft end, together with the first sprocket 71 and the chain, drives the second sprocket 59 to rotate. Since the second sprocket 59 is fixedly connected to the drive shaft 54, the entire drive shaft 54 ​​will rotate synchronously, thereby controlling the rotation of multiple material distribution discs 53 to feed materials.

[0040] Similarly, since the drive shaft 54 ​​and the actuating rod 51 are also connected by transmission, when the drive shaft 54 ​​rotates, it will also drive the actuating rod 51 to rotate. In this way, the actuating rod 51 can stir and feed the seeds and fertilizer inside the hopper 2, thus completing the stirring of seeds and driving the sowing.

[0041] It should be noted that in this embodiment, the sleeve 56 and the seeding tube 57 are fixedly connected, a spring plug 551 is embedded on the outside of the fixing rod 55, and a limiting hole 561 adapted to the telescopic end of the spring plug 551 is opened on the outside of the sleeve 56.

[0042] In this embodiment, the seeding tube 57 and the fixing rod 55 are detachably connected. This configuration allows for the disassembly and maintenance of the seeding tube 57. In this embodiment, the pipe 58 can be fixed to the end of the seeding tube 57 with a clamp. When blocked, the telescopic end of the spring plug 551 can be pressed to retract it, and then the sleeve 56 and the fixing rod 55 on the seeding tube 57 can be separated. The clamp can be removed to separate the pipe 58 and the seeding tube 57, thus enabling the cleaning and maintenance of the seeding tube 57. This further optimizes the ease of use of the device.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
