Description

Technology Field

[0001] The present invention relates to a tractor, and more specifically, to a tractor designed to operate stably on soft ground such as salt fields, rice paddies, and fields, belonging to the field of heavy equipment technology related to agriculture and land clearing. Background Technology

[0003] In salt field and agricultural operations, it is crucial to level the ground and perform proper compaction. Heavy equipment was used for these ground leveling and compaction tasks.

[0004] However, existing heavy equipment has the following problems in soft ground.

[0005] First, the ground subsidence problem

[0006] Specifically, because conventional heavy equipment has a small contact area and concentrated weight, it easily sinks or gets stuck in soft ground such as salt fields or rice paddies.

[0007] This causes work delays and requires additional equipment structural work.

[0008] In particular, salt fields made of mud experience more severe ground subsidence.

[0009] Second, uneven leveling and compaction effects

[0010] Specifically, while general heavy equipment can perform tillage operations in rice paddies and fields, there are limitations in leveling or compacting the surface while maintaining a constant force.

[0011] In particular, salt crystallization efficiency in salt fields can be reduced due to uneven ground conditions.

[0012] Third. Decline in work efficiency

[0013] In the existing method, leveling and compaction must be performed separately, which takes a long time and incurs additional costs.

[0014] If heavy equipment cannot move efficiently on soft ground, repetitive work becomes necessary.

[0015] Therefore, there is a need for the development of a tractor capable of stably leveling and compacting the ground even on soft ground such as salt fields, rice paddies, and fields. Prior art literature

Additionally, terms defined in commonly used dictionaries are not to be interpreted ideally or excessively unless explicitly and specifically defined otherwise.

[0037] Additionally, the singular form in this specification may include the plural form unless specifically stated otherwise in the text. As used in this specification, "comprises" and / or "comprising" do not exclude the presence or addition of one or more other components, steps, actions, and / or elements to the mentioned components, steps, actions, and / or elements.

[0039] FIG. 1 is a schematic perspective view showing the overall exterior of a tractor according to the present invention, FIG. 2 is an enlarged perspective view showing the compaction portion of the tractor according to the present invention, FIG. 3 is an enlarged view showing part 'a' of FIG. 2, and FIG. 4 is a side view showing the traction roller of the tractor according to the present invention.

[0040] As illustrated in FIGS. 1 to 4, a tractor (A) capable of leveling and compacting the ground in salt fields, rice paddies, and fields according to the present invention comprises a front wheel (100) that determines steering, a rear wheel (200) that generates driving force, and a traction roller (300) connected to the tractor.

[0041] First, the tractor (A) is composed of an engine, a fuel tank, a front wheel (100), a rear wheel (200), a transmission, and a body frame that houses the aforementioned configuration.

[0042] Additionally, the engine is operated by fuel stored in the fuel tank and generates power to rotate both rear wheels (200). Of course, the engine's power may also be used to rotate both front wheels (100). Furthermore, the fuel tank stores the fuel (e.g., diesel, gasoline, or biofuel) required for the engine to generate power.

[0043] Furthermore, the aforementioned front wheels feature an enhanced traction system. Specifically, rubber tracks or low-pressure tires are applied, enabling driving even on muddy terrain such as rice paddies.

[0044] In addition, the rear wheel (200) and the traction roller (300) are composed of compaction rollers.

[0045] Accordingly, the weight of the tractor can be effectively distributed through a multi-layered drive system composed of a front wheel (100), a rear wheel (200), and a traction roller (300), allowing it to operate stably on soft ground.

[0046] Meanwhile, the above-mentioned towing roller (300) is further provided with a towing frame (310), and the towing frame (310) is connected to a tractor by a towing pin (311).

[0047] Accordingly, the towing roller (300) can be selectively connected to the tractor by the towing pin (311).

[0048] Additionally, as shown in FIG. 4, the towing frame (210) is further equipped with a blade (320) for removing foreign matter from the towing roller (300). Accordingly, the blade (320) removes dirt, mud, etc. attached to the towing roller (300), thereby preventing the dirt and mud from adhering to the towing roller (300).

[0049] Additionally, a floating pad (400) is further provided on the front wheel (100), rear wheel (200), and traction roller (300). At this time, the floating pad (400) is attached to the outer surface of the front wheel (100), rear wheel (200), and traction roller (300).

[0050] Accordingly, by applying the floating pad system (Floating Pad System) using the floating pad (400), the tractor does not sink on soft ground (salt fields, rice paddies, fields).

[0051] In addition, it provides a buoyancy effect to distribute ground pressure over a wide area and prevents the tractor from getting stuck in mudflats or mud.

[0052] Furthermore, it has a larger surface area compared to conventional tractor wheels and enables stable driving even on wet ground.

[0053] In addition, the tractor is further equipped with a leveling blade (500).

[0054] At this time, the leveling blade (500) is attached to the lower part of the tractor and is configured to be raised, lowered, and angle-adjustable by hydraulics. Accordingly, it is possible to precisely level salt fields or rice paddy floors.

[0055] Accordingly, it performs the role of leveling the ground evenly while moving with the leveling blade (500). In particular, it leveles the uneven surface of the cultivated land, thereby improving waterway maintenance and cultivation efficiency.

[0056] Meanwhile, the rear wheel (200) and the traction roller (300) are equipped with a hydraulic cylinder that adjusts the pressing force and a vibration function.

[0057] Accordingly, the rear wheel (200) and the traction roller (300), which are composed of compaction rollers, perform the role of firmly compacting the flattened ground.

[0058] In addition, it moves while maintaining constant pressure to increase the density of the ground and increases the salt crystallization efficiency in salt fields.

[0059] Furthermore, it includes a vibration mechanism to provide a more powerful compaction effect.

[0060] In addition, the tractor of the present invention is equipped with a work mode and an automatic adjustment function.

[0061] Specifically, depending on the working environment, the depth and strength of the rear wheel (200) and traction roller (300) and the flattening blade (500), which consist of a compaction roller, can be automatically adjusted.

[0062] Furthermore, by combining GPS and an automatic leveling system, precise farmland management and salt field bottom leveling can be performed efficiently.

[0063] According to the present invention, weight is effectively distributed through a multi-layered drive system composed of front wheels, rear wheels, and a traction roller, allowing for stable operation on soft ground. Accordingly, it can move smoothly without subsiding even on soft ground such as salt fields, rice paddies, and fields.

[0064] In addition, the rear wheels and traction rollers can be used as compaction rollers to perform efficient leveling and floor compaction functions.

[0066] Although preferred embodiments of the present invention have been described in detail above, the technical scope of the present invention is not limited to the aforementioned embodiments and should be interpreted according to the claims. In this regard, those skilled in the art should consider that many modifications and variations are possible without departing from the scope of the present invention. Explanation of the symbols
