Description

Technical Field

[0001] This invention relates to the field of rotary tillers, and more particularly to a walk-behind rotary tiller. Background Technology

[0002] Rotary tillers are driven soil tillage machines that use rotating blades as their working parts, also known as rotary tillers. They are classified into two types based on the configuration of their rotary blade shafts: horizontal shaft type and vertical shaft type. Horizontal shaft rotary tillers, with the blade shaft positioned horizontally, are more commonly used and have a strong soil-breaking ability. In agricultural production, rotary tillers are widely used as important soil tillage machinery in operations such as farmland tillage and soil loosening. During operation, traditional rotary tillers cause fine soil particles to be stirred up and generate a large amount of dust as the rotary blades cut and turn the soil. This dust spreads rapidly in the air, not only polluting the surrounding environment and damaging air quality, but also posing a serious threat to the health of users. Long-term exposure to dusty environments can easily lead to respiratory diseases, eye discomfort, and other health problems, greatly affecting the comfort and safety of operation. In addition, after traditional rotary tillers complete the tillage operation, there are often some large clumps of soil in the soil. The presence of these large clumps of soil will affect the efficiency and quality of subsequent agricultural operations such as sowing and fertilization, leading to problems such as uneven sowing and unreasonable fertilizer distribution, which in turn will affect the growth and yield of crops. Therefore, how to reasonably solve the above problems is a question we need to consider. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a hand-held rotary tiller. This rotary tiller can effectively reduce dust generated during rotary tillage, preventing dust from spreading and affecting the user, thus facilitating practical use. In addition, it can also break up large clumps of soil after rotary tillage.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A walk-behind rotary tiller includes a frame; a rotary tilling mechanism, which includes a connecting seat connected to the right side of the frame, a mounting strip fixedly connected to the right side of the connecting seat, a vertical plate fixedly connected to the lower end of the mounting strip, a rotating shaft running through the vertical plate from front to back, the rotating shaft and the vertical plate being rotatably connected via bearings, and two rotary tilling frames symmetrically fixedly connected to the outer side of the rotating shaft; a drive mechanism for driving the rotating shaft to rotate, the drive mechanism including a mounting frame fixedly connected to the front side of the mounting strip, a drive motor mounted on the mounting frame, the output shaft of the drive motor being connected to the rotating shaft via a transmission component; a dust suppression mechanism for atomizing and settling the dust generated by rotary tilling with water to prevent dust from affecting the operator's use; and a soil breaking mechanism for further breaking up the soil clods turned up by the rotary tiller.

[0005] Preferably, the rotary tiller consists of a connecting frame and multiple rotary tiller blades, all of which are arranged at an angle on the connecting frame.

[0006] Preferably, the transmission component includes two pulleys, which are respectively mounted on the output shaft and the rotating shaft of the drive motor, and are connected by a transmission belt.

[0007] Preferably, a drive wheel assembly is installed at the lower end of the frame, and a hand handle is installed at the upper end of the frame.

[0008] Preferably, the dust suppression mechanism includes a water tank fixedly connected to the upper end of the mounting strip, an opening provided at the top of the water tank, a first piston cylinder fixedly connected to the rear side of the mounting strip, a first one-way pipe and a second one-way pipe communicating through the left side space of the first piston cylinder, one end of the first one-way pipe extending into the interior of the first piston cylinder and equipped with an atomizing nozzle, the other end of the first one-way pipe penetrating the opening and extending into the interior of the water tank, an L-shaped strip fixedly connected to the right side of the vertical plate, a hollow strip fixedly connected to the lower end of the horizontal part of the L-shaped strip, a strip-shaped inclined nozzle opened at the bottom of the inner part of the hollow strip, and the other end of the second one-way pipe extending into the interior of the hollow strip.

[0009] Preferably, the output shaft of the drive motor passes through the mounting strip and is fixedly connected to a rotating disk. A linkage rod is rotatably connected to the rear eccentric part of the rotating disk. A first piston plate that can slide left and right is provided inside the first piston cylinder. The other end of the linkage rod is rotatably connected to the right side of the first piston plate.

[0010] Preferably, both the first one-way pipe and the second one-way pipe are equipped with one-way valves. The flow direction of the one-way valve inside the first one-way pipe is one-way into the first piston cylinder from inside the water tank, and the flow direction of the one-way valve inside the second one-way pipe is one-way into the hollow bar from the first piston cylinder.

[0011] Preferably, the soil-breaking mechanism includes a rectangular plate fixedly connected to the lower end of the L-shaped strip. Two third piston cylinders are symmetrically fixedly connected to the lower end of the rectangular plate. Each of the two third piston cylinders is provided with a third piston plate that can slide up and down. The upper ends of the two third piston plates are elastically connected to the top of the corresponding third piston cylinder through springs. A piston rod is fixedly connected to the lower end of each of the two third piston plates. A shaking plate is fixedly connected to the lower end of the two piston rods.

[0012] Preferably, a V-shaped cutting plate is fixedly connected to the lower end of the shaking plate, and multiple soil-breaking rods are fixedly connected to the lower end of the V-shaped cutting plate at equal intervals.

[0013] Preferably, a second piston cylinder is fixedly connected to the left side of the first piston cylinder, and a second piston plate that can slide left and right is provided inside the second piston cylinder. The second piston cylinder is connected to the first piston cylinder, and the second piston plate is fixedly connected to the first piston plate by a fixing rod.

The left side space of the second piston cylinder, the horizontal pipe, the connecting pipe, and the inner top spaces of the two third piston cylinders are all filled with hydraulic oil.

[0014] Compared with the prior art, the beneficial effects of this invention are as follows: 1. The drive motor rotates, causing the first piston plate to move, thus atomizing water to settle the rotary tillage dust. This effectively prevents dust from spreading during rotary tillage, prevents operators from inhaling dust, protects the operator's respiratory health, improves the working environment, and makes rotary tillage operations safer.

[0015] 2. The water in the tank is atomized and sprayed out by utilizing the pressure change generated by the left and right movement of the first piston plate to suppress dust. This atomization dust suppression method has a high water utilization rate, achieving a good dust suppression effect with a small amount of water, while eliminating the need for complex energy-consuming devices, making it energy-saving and efficient.

[0016] 3. The movement of the first piston plate drives the second piston plate, which in turn causes the hydraulic oil to flow and push the third piston plate up and down. This, in turn, drives the soil-breaking rod to shake and break up the soil clods, further breaking up the large clods of soil after rotary tillage. This creates good soil conditions for subsequent sowing, ensures uniform sowing, and improves the quality of crop growth. Attached Figure Description

[0022] In this invention, the drive motor 8 starts and drives the rotating shaft 12 to rotate through the transmission components. The two rotary tillers 13, which are symmetrically fixed on the outside of the rotating shaft 12, rotate accordingly. The rotary tillers 13 are composed of a connecting frame and multiple inclined rotary tillers. During the rotation, they cut and turn the soil to achieve rotary tillage. At the same time, the drive wheel assembly 3 is used to move the whole unit to achieve mobile rotary tillage. When the output shaft of the drive motor 8 rotates, it drives the rotating disk 17 to rotate. The linkage rod 18, which is eccentrically connected to the rear side of the rotating disk 17, moves accordingly, thereby driving the first piston plate 31, which can slide left and right inside the first piston cylinder 19, to move left and right.

[0023] When the first piston plate 31 moves to the right, under the action of the one-way valve in the first one-way pipe 23, the water in the water tank 6 is drawn into the space on the left side of the first piston cylinder 19, and the water is atomized through the atomizing nozzle; when the first piston plate 31 moves to the left, under the action of the one-way valve in the second one-way pipe 21, the atomized water in the space on the left side of the first piston cylinder 19 enters the hollow strip 15 through the second one-way pipe 21, and is then sprayed out from the strip-shaped inclined nozzle 37 opened at the bottom of the hollow strip 15, so as to treat the dust generated by rotary tillage by atomizing water and prevent the dust from affecting the operator; When the first piston plate 31 moves left and right, it drives the second piston plate 33, which can slide left and right inside the second piston cylinder 20, to move synchronously through the fixed rod 32. The space on the left side of the second piston cylinder 20 is connected to the horizontal pipe 34 through the connecting pipe 24. The horizontal pipe 34 is connected to the inner top space of the two third piston cylinders 26. These spaces are filled with hydraulic oil. When the second piston plate 33 moves left and right, the hydraulic oil flows in each space, pushing the third piston plate 36, which can slide up and down inside the two third piston cylinders 26, to move up and down. The third piston plate 36 is elastically connected to the inner top of the corresponding third piston cylinder 26 through the spring 35. Its up and down movement drives the piston rod 27, the shaking plate 28, the V-shaped cutting plate 30 and multiple soil breaking rods 29 to shake up and down, further breaking up the soil clods turned up by the rotary tiller, thus facilitating subsequent sowing.
