Description

Technical Field

[0001] The utility model relates to the field of mowing equipment, in particular to an orchard remote-controlled forage harvester. Background Art

[0002] There are various forms of lawn mowers in modern technology, mainly backpack and hand-push types. These two types of equipment have high requirements for operators. They must walk through the entire orchard area to complete the mowing operation. Moreover, as the operation time lasts, the operator will have weakness in his limbs, and the fruit trees may be damaged during the mowing process. Compared with the traditional backpack lawn mower, this equipment is flexible, compact and easy to operate, which can greatly reduce the labor intensity of farmers and greatly improve the efficiency of work. Although this type of remote control lawn mower has many advantages, its existence is limited to "chopping grass" rather than "mowing grass", that is, the weeds in the orchard cannot be collected for secondary use, which is also a waste for fruit farmers. If there is a device that can not only cut the weeds in the orchard, but also collect them and use them to feed herbivores such as cattle and sheep, the weeds can be reasonably used. Therefore, it is necessary to design an orchard remote control forage harvester to solve the above problems. Utility Model Content

[0003] In view of the above-mentioned defects of the prior art, the utility model discloses a remote-controlled grass harvester for an orchard, which can perform grass cutting operations under low fruit trees and transmit the grass to one side of the grass cutter.

[0004] To achieve this purpose, the utility model adopts the following technical scheme: This is an orchard remote control forage harvester, including a frame (28), characterized in that it also includes: a driving motor (16), a gasoline engine (17), a generator (29), an electric push rod (24) and a distribution box (1) installed on the frame (28), a remote control receiver (30), and a height adjustment mechanism (4). The frame is connected to the reciprocating cutter through the height adjustment mechanism, so that the height of the cut stubble can be adjusted according to the specific terrain conditions. The height adjustment mechanism includes a slider guide rail assembly and a belt tensioner. Through the electrical and mechanical connection, the device can run smoothly.

[0005] As a further solution of the utility model: the power drive device comprises a drive motor (16) and a tire (3), the drive motor is arranged on both sides of the frame (28), and the output shaft of the drive motor is rigidly connected to the rotating shaft of one of the tires, and the tire (3) is arranged on the outside of the drive motor.

[0006] As a further solution of the utility model: an LED lighting lamp group (14) is installed on the frame (28), and the lighting lamp group faces the front of the frame and is symmetrical on both sides.

[0007] As a further solution of the utility model: the reciprocating cutter (10) is connected to the eccentric wheel (50) through a connecting rod (49), and the eccentric wheel (50) and the shaft (47) are coaxially matched.

[0008] As a further solution of the utility model: the grass-pulling device transmits the power of the gasoline engine to the T-axis (37) through the belt (5), and then drives the driving pulley (42) through the belt (40), so that the grass-pulling device works and smoothly transmits the grass to one side of the orchard remote-controlled grass harvester.

[0009] As a further solution of the utility model: the output shaft of the gasoline engine (17) is connected to the rotating shaft of the generator (29), so that the battery pack (20) can be replenished with energy in time while the orchard remote-controlled forage harvester is operating normally, thereby improving the endurance of a single operation.

[0010] As a further solution of the utility model: a cooling fan (2) is arranged on the left side of the distribution box (1) so as to timely reduce the temperature of the electronic components in the distribution box and ensure that the components therein will not be damaged.

[0011] As a further solution of the utility model: the electric push rod (24) and the electric push rod (25) satisfy a linear complementary relationship to ensure that the belt tensioner (34) can be adjusted in time while the cutter is lifted, ensuring that there is sufficient friction between the pulley (32) and the pulley (35), thereby reducing power loss.

[0012] As a further solution of the utility model: there is an electrical connection between the drive motor (16), the remote control receiver (30) and the distribution box (1), and a single-chip control module, a voltage conversion module, a relay module, a temperature control module and a fault alarm module are installed inside the distribution box, and they are all connected by wires.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] The reciprocating cutter can not only increase the range of mowing operations and avoid the phenomenon of the mower tires crushing the straw, but also adjust the cutting height in time when equipped with a height adjustment device, thereby improving the passing performance of the mower.

[0015] When the orchard remote-controlled forage harvester is operating, the grass will be transferred to one side through the grass-moving device behind the reciprocating cutter for easy subsequent collection; in addition, the gasoline engine will drive the cutter while charging the battery pack to increase the endurance of the equipment.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] A remote-controlled grass harvester for an orchard, such as Figures 1 to 2As shown, the invention comprises a frame (28), a battery pack (20), a driving motor (16), a gasoline engine (17), a generator (29), an electric push rod (24), a distribution box (1) mounted on the frame (28), a remote control receiver (30), and a height adjustment mechanism (4). The frame is connected to the reciprocating cutter through the height adjustment mechanism, so that the cutting height can be adjusted according to the specific terrain conditions. The height adjustment mechanism comprises a slider guide assembly and a belt tensioner. Through the electrical and mechanical connection, the device can run smoothly.

[0025] When the device is in operation, the gasoline engine (17) is first started, and then the power is transmitted to the generator (29) and the rotating shaft through the belt to prepare for the operation of the cutter, and then the power is transmitted to the rotating shaft (36) through the belt (5), thereby driving the T-type gear box to operate, and finally the pulley (39) is connected to the pulley (43) through the belt (40) to ensure that the two can rotate synchronously. At this time, the grass-pulling device will be able to work normally. The end of the right rotating shaft (13) is also connected with a helical gear box (46). The two are rigidly connected, and the purpose is to provide the required power for the rotation of the reciprocating cutter. The driving assembly of the cutter is a cutter bracket (48), a connecting rod (49), an eccentric wheel (50), and an eccentric wheel shaft pin (51). That is, the circular motion is converted into reciprocating linear motion through the cooperation of the eccentric wheel and the connecting rod, thereby driving the cutter to work.

[0026] The height adjustment mechanism (4) includes an electric push rod (24), an electric push rod (25) and a belt tensioning bracket (26). The housing of the electric push rod is hinged with the bottom bracket, and the telescopic rod of the electric push rod is hinged with the connecting rod to realize power connection. The overall structure is more concise under the premise of satisfying the controllable stroke. The power source of the walking mechanism is the driving motor (16). A 4*250W reduction motor is used to drive the tire (3). The tire and the motor shaft are also rigidly connected to ensure direct transmission of power.

[0027] Preferably, an LED lighting group (14) is installed on the vehicle frame. The LED lighting group (14) faces forward and is symmetrically distributed, which is suitable for nighttime operations, thereby improving the functionality of the system.

[0028] Preferably, a bottom baffle (11) is installed below the grass-pulling belt (12), thereby avoiding the phenomenon of "leaking grass" and being able to collect the straw as fully as possible.

[0029] like Figure 4As shown, the belt tensioning device includes a belt (5), an electric push rod (25), a belt tensioning bracket (26), a rotating shaft (31), a pulley (32), a rotating shaft (33), a belt tensioning wheel (34), a pulley (35), and a rotating shaft (36). The electric push rod is installed directly below the belt tensioning bracket, and its output circuit is connected to the remote control receiver (30). Therefore, the telescopic length of the electric push rod can be changed by adjusting the position of the remote control push rod, and the two show a linear relationship.

[0030] like Figure 6 As shown, the power source of the reciprocating cutter (10) is to transmit power to the bevel gear box (46) through the right rotating shaft (13), and then drive the eccentric wheel (50) to rotate. Through the cooperation of the connecting rod (49), the circular motion is converted into reciprocating linear motion, so that the cutter can perform mowing operations.

[0031] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
