Description

small power plow device

[0001] The present invention relates to a plowing device, and more particularly, to a small power plowing device that can simultaneously plow and level the land even in narrow areas such as rice paddy ridges.

[0002] If the soil is soft and uneven, the seed drill will not penetrate the soil and the seeds will end up on the surface, preventing them from planting. Therefore, the soil must be broken up and made soft before sowing. A plow is used for this purpose. Traditionally, plowing was done by attaching a plow to an animal or machine.

[0003] Today, plows are commonly mounted on tractors. However, this makes them unsuitable for use in confined spaces like field ridges, rice paddy ridges, and vegetable gardens. Therefore, before sowing seeds in confined spaces like field ridges or rice paddy ridges, workers had to repeatedly use a hoe to dig up the soil where the seeds would be sown. This process was arduous and, when performed in large areas, required excessive manpower.

[0004] The present invention has been devised to solve the problems of the prior art, and the purpose of the present invention is to provide a small power plow device that can easily plow the land and perform leveling work at the same time using power even in places where mechanization is impossible due to narrow width.

[0005] In order to achieve the above object, a small power plow device according to the present invention comprises a support frame extending in the front-back direction, a handle portion coupled to the rear end of the support frame and configured to be held and pushed by a worker by hand, a power generation portion coupled to the rear end of the support frame, a power transmission shaft having a rear end coupled to the power generation portion and extending in the front-back direction and rotating by the operation of the power generation portion, a gear box portion coupled to the front end of the support frame and having a gear portion connected to the front end of the power transmission shaft to change the rotational direction of the power transmission shaft, and including an output rotational shaft connected to the gear portion and extending in the left-right horizontal direction, a shaft coupling portion coupled to the output rotational shaft, a plurality of spokes extending radially from the shaft coupling portion, and a wheel rim coupled to the end of the spokes, the rotary wheel configured to be rotatable in a state perpendicular to the ground, a plurality of crushing portions coupled to the wheel rim at intervals along the outer circumferential surface of the wheel rim and protruding outward from the wheel rim, and an upper end coupled to the lower surface of the rear end of the support frame to rotate in the up-and-down direction. It comprises a column member that extends, a pressing plate that is connected to the lower end of the column member and whose bottom touches the ground, a foreign matter removal part that is connected to the front end of the pressing plate in a plurality of pieces at intervals and protrudes forward of the front end of the pressing plate, and a plow blade that is connected to the lower end of the pressing plate in a rear portion of the foreign matter removal part in a shape that protrudes downward from the pressing plate, has a sharp lower end, and is thinner in the left-right direction than the front-back direction width, and is provided in a plurality of pieces at intervals from each other.

[0006] In addition, it is preferable that the shredding part is configured to include a connecting plate that is protruded and relatively wide and faces the rotational direction of the rotating wheel, and a pair of shredding plates that are connected to the left and right ends of the connecting plate at right angles to each other and face each other.

[0007] In addition, it is preferable that one of the plow blades is coupled to the left and right center of the front part of the press plate, and two are coupled to the left and right sides of the rear part of the press plate at intervals from each other.

[0008] In addition, it is preferable that the foreign substance removal part has a sharp front end and a width in the left-right direction that is thinner than the width in the front-back direction, and that the upper part of the part located in front of the pressing plate slopes downward as it goes forward.

[0009] Additionally, it is preferable that the support frame be provided with a kickstand that can be unfolded to touch the ground when not in use, allowing the small power plow device to be placed upright.

[0010] As described above, according to the small power plow device of the present invention, since the entire width of the device is narrow from side to side, plowing by the device is possible even in places where a tractor cannot be used due to the narrow width, such as between rice paddies and field ridges, and since power is used for the ground surface breaking work, manpower is greatly reduced, and after the rotating wheel first plows the ground strongly and effectively, secondly, the foreign matter is removed by the foreign matter removal unit following behind, and then the plow blade plows the ground again to make it smooth, and since the pressing plate presses the ground surface flat, not only plowing but also the ground leveling work can be completed at once, so the work is efficient and simple, and since the device is small, it has the advantage of being convenient to transport and store.

[0012] Figure 2 is a right side view showing a small power plow device according to the present invention.

[0013] Figure 3 is a partial perspective view of a small power plow device according to the present invention.

[0014] Hereinafter, specific embodiments of the present invention will be described in detail with reference to the attached drawings.

[0015] A small power plow device according to the present invention is configured to include a support frame (10), a handle portion (20), a power generation portion (30), a power transmission shaft (40), a gear box portion (50), a rotating wheel (60), a crushing portion (70), a pillar member (80), a pressing plate (90), a foreign matter removal portion (100), a plow blade (110), and a kick stand (120).

[0016] The support frame (10) is a basic skeleton of a small power plow device according to the present invention, and is configured to include a front portion of a hollow circular pipe structure extending in a straight direction forward and backward, in which a power transmission shaft (40) is installed inside, and a rear portion that is bent at the rear end of the portion where the power transmission shaft (40) is inserted and descends diagonally downward, and a rear portion on which a power generation unit (30) is coupled.

[0017] The handle part (20) is composed of a handle stem (21) that extends upward from the rear end of the support frame (10) and a handle (22) that is bent to form a rectangle and is located at the rear by combining with the upper end of the handle stem (21).

[0018] On the left side of the handle (22), an operating unit (not shown) is provided as an acceleration lever connected to the power generation unit (30) to control the acceleration and deceleration of the power generation unit (30).

[0019] The power generation unit (30) is fixedly mounted on the rear part of the support frame (10), and the power generation unit (30) in this embodiment adopts an engine that uses oil as fuel, but may also adopt an electric motor that operates on electricity.

[0020] The power transmission shaft (40) is connected at the rear end to the output of the power generation unit (30) and rotates by the operation of the power generation unit (30). The power transmission shaft (40) extends in the front-back direction while penetrating the interior of the front part of the support frame (10).

[0021] The front end of the power transmission shaft (40) is connected to the gear device and reducer inside the gearbox section (50), so that the power transmission shaft (40), which is rotated at high speed by the power generation section (30), is reduced while passing through the gearbox section (50), and the direction of the rotation axis is bent at a right angle by the gear section that changes the direction of power transmission, such as a bevel gear. As a result, the output rotation axis of the gearbox section (50) extends in the horizontal direction.

[0022] The rotating wheel (60) is composed of an axle joint (61), a spoke (62), and a wheel rim (63).

[0023] The shaft coupling part (61) is coupled with the output rotation shaft of the gearbox part (50) and rotates by the rotation of the output rotation shaft of the gearbox part (50). A total of four wheel spokes (62) are provided, and the inner end of each wheel spoke (62) is coupled with the shaft coupling part (61) and extends radially. The wheel rim (63) is a circular ring-shaped member that is coupled to the outer end of the wheel spoke (62) and rotates as one unit with the shaft coupling part (61) and the wheel spoke (62).

[0024] The crushing member (70) is a member that is joined to the wheel rim (63) at regular intervals along the outer surface of the wheel rim (63) and protrudes outward from the wheel rim (63). The crushing member (70) repeatedly enters the ground and comes out of the ground according to the rotation of the rotating wheel (60), thereby crushing the ground on which the seeds are to be sown to become smooth and even.

[0025] The direction of rotation of the rotating wheel (60) is such that the crushing part (70) located at the very front of the device falls from above and strikes the ground surface.

[0026] The crushing unit (70) is configured to include a connecting plate (71) in the shape of a rectangular plate that is connected to the wheel rim (63) and has a protruding and relatively wide surface facing the rotational direction of the rotating wheel, and a pair of rectangular plate-shaped crushing plates (72) that are connected at right angles to the left and right ends of the connecting plate (71) and face each other. When the cross-section of the part where the connecting plate (71) and the crushing plate (72) are attached is cut, it forms an 'H' shape.

[0027] The crushing plate (72) is configured to protrude further outward than the connecting plate (71), and the connecting plate (71) is coupled to the wheel rim (63) at an angle with respect to the diameter of the rotating wheel (60) so that the portion of the crushing section (70) closest to the wheel rim (63) touches the ground surface. Since the connecting plate (71) is coupled at an angle, in order to reinforce durability, both ends of the reinforcing member (73) are coupled to the connecting plate (71) and the wheel rim (63), respectively, thereby preventing the connecting plate (71) from being further bent.

[0028] The pillar member (80) is a part that extends vertically in the upper and lower directions and is connected to the lower part of the rear part of the support frame (10) at the upper end, and also serves to support the power generation part (30) located above from below.

[0029] The pressing plate (90) is a plate-shaped member that is connected to the lower part of the pillar member (80) and is wide in the horizontal direction and has a flat bottom surface. The bottom surface of the pressing plate (90) touches the ground and presses the ground, thereby leveling the surface of the soil through which the device according to the present invention passes.

[0030] The foreign substance removal unit (100) is installed so that the rear part is connected to the lower surface of the front part of the pressing plate (90) and the front part extends forward longer than the front end of the pressing plate (90).

[0031] The foreign substance removal unit (100) is provided in three pieces, one each on the left and right ends of the front end of the pressing plate (90) and one each on the left and right center.

[0032] The foreign substance removal unit (100) is configured to be thin in width from side to side by being fixed in a vertically erected form with a thin flat plate-shaped member. In the present embodiment, the foreign substance removal unit (100) is configured to have a sharp front end and an upper end of a portion located in front of the pressing plate (90) that slopes downward as it moves forward. However, the shape of the foreign substance removal unit (100) is not limited to this shape, and may be configured to extend forward like an awl.

[0033] The plow blade (110) is positioned at the rear of the foreign substance removal unit (100), and the upper end is combined with the lower surface of the pressing plate (90) so that it protrudes downward from the pressing plate (90) and stands vertically. When viewed from the side, the lower end is a pointed triangular plate-shaped member, and the left and right widths are configured to be thin and uniform.

[0034] It is preferable that a total of three plow blades (110) be provided, one attached to the left and right center of the front part of the pressing plate (90) and two attached to the left and right edges of the rear part of the pressing plate (90) at intervals from each other.

[0035] The kickstand (120) is connected to one side of the support frame (10), and is configured to be unfolded so as to touch the ground when not in use, similar to a kickstand (120) used in a bicycle, and to be folded up and raised so as not to touch the ground when in use. When the small power plow device is not in use, the kickstand (120) is unfolded so that the lower part touches the ground, thereby allowing the device to stand upright without falling over, even if it is slightly tilted.

[0036] The carrying handle (not shown) is a rod-shaped member that extends long to the right from one side of the handle stem (21), and is a part configured to be held when lifting and moving the entire small power plow device.

[0037] The operation of the small power plow device according to the present invention configured as described above is described as follows.

[0038] The worker only needs to hold the handle (22) of the handle part (20) with both hands and slowly push it forward to move forward.

[0039] When the power generating unit (30) is operated, the power transmitted as the power generating shaft (40) rotates is reduced while passing through the gearbox unit (50), and the direction of power transmission is changed to a right angle to rotate the shaft coupling unit (61) of the rotating wheel (60), and accordingly, the wheel spokes (62) and the wheel rim (63) rotate as one, and the crushing unit (70) moves downward and digs into the soil. At this time, the crushing plates (72) on the left and right sides of the crushing unit (70) first enter the soil and grind the soil, and then the wide connecting plate (71) receives a reaction force when it hits the soil, and mixes the soil by pushing it backward. Through the action of the crushing unit (70) digging, turning over, and mixing the soil, the soil becomes soft and even.

[0040] The soil that has been first ground by the crushing unit (70) is then ground a second time by the plow blade (110) that follows. Before passing the plow blade (110), the foreign matter removal unit (100) passes through the soil first. The foreign matter removal units (100) have multiple protruding forward like the claws of an animal and are installed in parallel to each other, so that they serve to lift things that are caught, such as grass, in the soil above the ground. By removing things like grass in the soil in advance by the foreign matter removal unit (100), the plow blade (110) can advance easily without being caught by grass or other foreign matters.

[0041] The plow blade (110) has one in the front and two in the back, so it divides the soil once in the front and then divides the soil again on the left and right sides right behind, thereby making the soil soft.

[0042] As described above, the present invention has been described only with respect to preferred specific examples. However, it is obvious to those skilled in the art that various modifications and variations are possible within the technical scope of the present invention based on the above specific examples, and it is also natural that such modifications and variations fall within the scope of the appended claims.
