Description

Technical Field

[0001] The present invention relates to the field of agricultural machinery and equipment, and in particular to a ridging machine, specifically a ridging machine for greenhouses. Background Art

[0002] In order to meet the growing needs of people's living standards, the facility agriculture in our country is constantly developing. Among them, as the main production type of facility agriculture, the area of solar greenhouses is also constantly increasing. In order to make full use of sunlight, the structural form of solar greenhouses is generally east-west oriented, characterized by a long east-west direction and a short north-south direction. There is a wall at the north end of the greenhouse and an east-west passage is left against the north wall. According to agronomic requirements, fruits, vegetables and other crops in the greenhouse generally need to be planted on soil ridges.

[0003] The planting modes of solar greenhouses are divided into two types: ridging in the east-west direction and ridging in the north-south direction. Ridging in the north-south direction is more conducive to the growth of crops and is also conducive to picking, irrigation, etc. Therefore, most solar greenhouses adopt ridging in the north-south direction. Correspondingly, since the north-south span of solar greenhouses is generally only 6 - 10 meters, when ridging in the north-south direction, it is impossible to reserve a large area at the north and south ends for the equipment to turn around and change rows. Therefore, the existing mechanical equipment is not suitable for ridging in the north-south direction in solar greenhouses.

[0004] Through investigation and research, it is found that there is no suitable mechanical equipment for ridging in the north-south direction in solar greenhouses on the market. The currently commonly used ridging mechanical equipment is a walking tractor. Because the walking tractor has a small horsepower and is difficult to operate, the ridging effect is not good, the ridge shape is not neat, and the compaction effect is poor, which affects the planting quality. Moreover, there are also problems such as difficulty in turning around and changing rows in solar greenhouses, and it is easy to damage the already formed ridges when turning around and changing rows. Another ridging method is manual ridging. However, manual ridging has low efficiency, high cost, and at the same time, manual ridging also has problems such as an uneven ridge shape and a poor compaction effect, which affect the subsequent planting quality.

[0005] Therefore, how to provide a ridging machine for greenhouses has become an urgent technical problem for those skilled in the art. Summary of the Invention

[0006] In order to overcome the deficiencies in the background art, the present invention provides a ridging machine for greenhouses. The present invention breaks the working mode of general agricultural equipment and solves the problem of difficult turning around and changing rows when the equipment ridges in the north-south direction, etc.

[0007] To achieve the above invention object, the present invention adopts the following technical solutions: A ridging machine for greenhouse, comprising a track, a rail vehicle and a ridging main unit. The track is laid on the passage at the north end of the greenhouse. A rail vehicle moving in the east-west direction is arranged on the track. A ridging main unit moving in the north-south direction is arranged on the rail vehicle. The rail vehicle carries the ridging main unit and moves in the east-west direction.

A soil gathering mechanism is arranged at the lower part at the rear side of the vehicle frame. The soil gathering mechanism is connected to the intermediate gearbox. The intermediate gearbox is connected to a soil gathering motor arranged above the soil gathering mechanism. A ridge compaction wheel lifting mechanism is arranged on the vehicle frame in front of the soil gathering mechanism. The ridge compaction wheel lifting mechanism and the soil gathering mechanism are connected to the hydraulic system, and the hydraulic system respectively drives the ridge compaction wheel lifting mechanism and the soil gathering mechanism to lift. A ridge compaction wheel is arranged on the ridge compaction wheel lifting mechanism. The ridge compaction wheel is connected to a ridge compaction motor arranged on the ridge compaction wheel lifting mechanism. An electrical control system is arranged above the vehicle frame. The electrical control system is respectively connected to the traveling motor, the ridge compaction motor, the soil gathering motor and the remote control receiver. The electrical control system is powered by the lithium battery or uses mains power supply.

[0010] For the ridging machine for greenhouse, when the electrical control system is connected to the lithium battery, an inverter is arranged between the lithium battery and the electrical control system.

[0011] For the ridging machine for greenhouse, the remote control receiver is arranged on one side of the vehicle frame.

[0012] For the ridging machine for greenhouse, the traveling mechanism is any one of a crawler-type traveling mechanism or a wheel-type traveling mechanism.

[0013] For the ridging machine for greenhouse, when the electrical control system works in the greenhouse, it is connected to the mains power supply. When transferring between greenhouses, the lithium battery supplies power through the inverter to convert the low voltage of 72V into AC 220V.

[0014] For the ridging machine for greenhouse, the electrical control system includes a PLC, a servo motor controller, a power conversion switch and a frequency converter.

[0015] The described ridging machine for greenhouse, the hydraulic system includes a hydraulic oil tank, a hydraulic pump, a hydraulic pump motor and a hydraulic cylinder. One end of the hydraulic pump is connected to the hydraulic oil tank, the other end of the hydraulic pump is connected to the hydraulic pump motor, and the hydraulic pump is connected to the hydraulic cylinder.

[0016] Due to the adoption of the above technical solution, the present invention has the following beneficial effects: The present invention lays the track on the passage at the north end of the greenhouse, sets a rail car moving in the east-west direction on the track. The ridging main machine works from south to north.

During implementation, when the hydraulic system 309 drives the soil gathering mechanism 313 to lift, the soil gathering mechanism 313 is connected to the vehicle frame 314 through a soil gathering mechanism hinge 315. In this way, the hydraulic cylinder 30904 in the hydraulic system 309 can drive the soil gathering mechanism 313 to lift.

[0030] It should be noted that the applicant has separately applied for patents for the rail vehicle 2 and the ridge-shaped compaction wheel lifting mechanism 308 involved in the present invention, and the specific structures will not be elaborated here.

[0031] During specific implementation, a motor is installed on the rail vehicle 2 of the present invention to drive the rail vehicle to travel, and the power supply is the mains electricity in the greenhouse.

[0032] In the ridging main machine 3 of the present invention, the traveling mechanism 305 is preferably a crawler-type traveling mechanism, which mainly consists of a driving wheel, a guiding wheel, a supporting wheel, and a crawler, and is responsible for the traveling of the whole machine. Since the crawler-type traveling mechanism is a conventional structure in the art, it will not be elaborated here.

[0033] There is one traveling motor 304 on each of the left and right sides to drive the traveling mechanism. During implementation, by controlling the rotation speeds of the two traveling motors 304, functions such as the forward movement, backward movement, left turn, and right turn of the ridging main machine 3 can be achieved.

[0034] The inverter 303 is used to convert the 72V power supply of the lithium battery 301 into 220V voltage to supply power to each motor.

[0035] The electrical control system 302 mainly includes a PLC, an inverter, a power conversion switch, and motor servo controller components, which are used to control the actions of each motor. When the ridger works in the greenhouse, it uses commercial power. When transferring between greenhouses, the power supply is switched to the built-in lithium battery of the ridger as the power source.

[0036] The soil gathering motor 310 is used to drive the soil gathering mechanism 313 to operate.

[0037] The ridge type compaction wheel lifting mechanism 308 connects the soil gathering mechanism 313 and the ridge type compaction wheel 307, enabling both to move independently and interact with each other to achieve ridging operations.

[0038] The intermediate gearbox 311. The soil gathering motor 310 transmits power to the gearbox through a chain. The gearbox undergoes speed change and transmits the power to the soil gathering mechanism 313 to achieve soil gathering operations.

[0039] The ridge type compaction motor 306 provides power to the ridge type compaction wheel 307.

[0040] The function of the soil gathering mechanism 313 is to gather the already rototilled land into initial ridges.

[0041] When implementing the present invention, the track 1 is laid on the passage of the solar greenhouse. The track vehicle 2 is driven by a motor and can move on the track 1. Both the track vehicle 2 and the ridging main machine 3 are in a remote control mode. One remote control can simultaneously control the actions of the track vehicle 2 and the ridging main machine 3, so the operation is also very easy and convenient. During operation, the ridging main machine 3 retreats from the track vehicle 2 and moves backward to the southernmost end of the solar greenhouse. At this time, the ridging main machine 3 starts ridging operations from south to north. After the ridging main machine 3 walks to the track vehicle 2, it stops operating and simultaneously walks onto the track vehicle 2. The track vehicle 2 drives the ridging main machine 3 to move together along the track 1 to the right by a ridge distance. At this time, the ridging main machine 3 retreats from the track vehicle 2 again and moves backward to the southernmost end of the solar greenhouse. The ridging main machine 3 starts ridging operations from south to north again. This cycle continues until the ridging operations for the entire solar greenhouse are completed. When it is necessary to transfer fields after completing the operations, the changeover switch switches the commercial power to lithium battery power supply, and the ridger can walk between greenhouses relying on its built-in lithium battery.

[0042] The present invention makes full use of the passage at the northern end of the solar greenhouse, sets the track 1 and the track vehicle 2 on the passage, and realizes the row change of the ridging main machine 3 by the combined movement of the ridging main machine 3 and the track vehicle 2, avoiding damage to the completed ridging operations, and preferably solving the difficulty of equipment row change in the narrow space of the solar greenhouse. At the same time, this equipment uses commercial power in the greenhouse and lithium battery power supply when transferring between greenhouses, and the switching between the two power sources is convenient. Compared with using a diesel engine or a gasoline engine as the power, it is both environmentally friendly and reduces the equipment use cost, etc.

[0043] The advantages of the present invention are as follows: 1. The present invention solves the problem of difficult ridging turning and row changing in a short north-south distance in a solar greenhouse; 2. The present invention uses the movement of a rail vehicle on the track for row changing, without damaging the completed ridging operation; 3. The one-way operation mode of the present invention does not require the action of turning around and changing rows at the south end of the greenhouse, and also solves the problem of the equipment turning around and changing rows at the south end of the solar greenhouse, etc.

[0044] The parts not described in detail above are prior art and will not be elaborated.

[0045] The embodiments selected herein for disclosing the object of the present invention are considered suitable at present. However, it should be understood that the present invention is intended to include all variations and improvements of all embodiments that fall within the scope of this concept and invention.
