Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of agricultural machinery, and in particular to an integrated plowing and land leveling machine for a vegetable greenhouse. Background Art
[0002] Vegetable greenhouses are framed and film-coated structures with excellent thermal insulation properties, allowing people to enjoy out-of-season vegetables. Typically, a vegetable greenhouse uses a bamboo or steel frame covered with one or more layers of insulating plastic film, creating a greenhouse space. The interior of a greenhouse typically contains columns, pipelines, and temperature control equipment. Furthermore, the limited width and height (especially for solar greenhouses) make it difficult for traditional large tractors and plowing equipment to enter and operate efficiently. Using small tractors also results in low tillage efficiency, and maneuvers such as turning and reversing within the greenhouse are also difficult.
[0003] In summary, the applicant believes that designing an all-in-one machine that can horizontally till the land and level the land can facilitate operations inside the greenhouse. Through project search, it was found that a patent with application number 2009200659988 discloses a swing-type rotary tiller, which consists of a power, a gearbox, a swing structure, and a rotary tillage structure. When plowing the field, the swing structure leads the rotary tillage structure to perform horizontal tillage, and each time the rotary tillage structure completes a horizontal tillage procedure, the entire tiller moves forward intermittently for a short distance. The technical solution recorded in the specification is a multi-link rocker arm structure. As its swing structure, the above technical solution can achieve the function of horizontal plowing, but is limited by its multi-link rocker arm structure. When swinging, the rotary tillage structure moves in a circular trajectory, and there is a dead angle when used in a greenhouse. Moreover, the horizontal swing amplitude of the rotary tillage structure is related to the length of the rocker arm. When the rocker arm is long enough, the pillars in the greenhouse will hinder the swing of the rocker arm. Therefore, it is not suitable for use in a greenhouse, and this technical solution also does not have the function of land preparation. For this reason, the inventor proposes a vegetable greenhouse plowing and land preparation integrated machine that can plow the land horizontally and avoid the pillars. Summary of the Invention
[0004] The purpose of the present invention is to provide a vegetable greenhouse plowing and land preparation machine to solve the problems raised in the background technology. The specific technical solution is as follows:
[0005] In order to achieve the above-mentioned objectives and other related objectives, the present invention provides an integrated plowing and land leveling machine for vegetable greenhouses, including a swinging structure, a rotary plowing structure and a control system. The swinging structure includes a mounting frame, a main beam, a telescopic structure and a main beam driving structure. The main beam is rotatably mounted on the mounting frame. The main beam driving structure is arranged between the mounting frame and the main beam. The main beam driving structure is used to drive the main beam to rotate.

The main shaft is rotatably installed between the two side plates, and the driving mechanism is arranged on the side plates.
[0009] Preferably, the telescopic structure also includes a rotary joint, which is connected to the telescopic structure and rotatably mounted on the main connecting rod. A ring bevel gear is provided on one side of the rotary joint. An adjusting motor is fixedly connected to the main connecting rod, and a bevel gear is provided at the output end of the adjusting motor. The bevel gear is meshed with the ring bevel gear. A level sensor is provided on the upper baffle, and the adjusting motor and the level sensor are electrically connected to the control system respectively.
[0010] Preferably, the rotary plow structure further includes a land leveling scraper. There are two land leveling scrapers, which are respectively arranged on the front and rear sides of the upper baffle. The land leveling scrapers are connected to the upper baffle through a third hydraulic rod, and the operation of the third hydraulic rod is controlled by a control system.
[0011] Preferably, the control system includes a hydraulic system, a power supply system, an MCU main control box and a control panel.

[0014] By setting the main beam, telescopic structure and main beam drive structure, under the control of the control system, the telescopic structure and the main beam drive structure can work together to make the rotary plow blades plow the land reciprocatingly and horizontally. The tractor only needs to move forward one or two times to plow the soil in the greenhouse, eliminating the need for frequent turning back and forth and backward. Moreover, this structure does not have a multi-link rocker arm structure. When swinging, the rotary tillage structure reciprocates in a straight line. There is no dead angle when used in the greenhouse, and it can also avoid obstacles such as columns. It is very suitable for use in vegetable greenhouses. BRIEF DESCRIPTION OF THE DRAWINGS

The driving mechanism is provided on the side plates 213. In some embodiments, the driving mechanism is composed of a motor and a reducer.
[0022] In some embodiments, the telescopic structure 130 also includes a rotary joint 150, which is connected to the telescopic structure 130, and the rotary joint 150 is rotatably installed on the main connecting rod 211. A ring bevel gear 160 is provided on one side of the rotary joint 150, and an adjusting motor 170 is fixedly connected to the main connecting rod 211.

The level signal of the upper baffle 212 is detected by the level sensor 190 and sent to the control system. The control system then controls the adjustment motor 170 to work and keep the upper baffle 212 level.
[0023] In some embodiments, the rotary plow structure 200 also includes a ground leveling scraper 240. There are two ground leveling scrapers 240, which are respectively arranged on the front and rear sides of the upper baffle 212. The ground leveling scraper 240 is connected to the upper baffle 212 through a third hydraulic rod 250. The third hydraulic rod 250 is controlled by a control system.
