Technical Field

[0001] The invention relates to a multifunctional multi-crop harvesting device, belonging to the field of crop harvesting tools. Background Art

[0002] Most of the existing crop harvesting devices have a single function. For example, a wheat harvester can only be used to harvest wheat, while the harvesting of tobacco plants can only be done with special tools. At the same time, the application of pesticides to tobacco can only be done with special pesticide spraying devices.

[0003] That is, there is a lack of a multifunctional multi-crop harvesting device that can be applied to a variety of crops and used across crops to improve the utilization rate of agricultural machinery. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide a multifunctional multi-crop harvesting device that can be applicable to a variety of crops and used across crops to improve the utilization rate of agricultural machinery; it can overcome the shortcomings of the prior art.

[0005] The objective of the present invention is achieved through the following technical solutions: The invention discloses a multifunctional multi-crop harvesting device, which comprises a vehicle body, a reciprocating cutting device and a driving device of the reciprocating cutting device are arranged on the vehicle body, and a lifting device of the reciprocating cutting device is movably connected to the vehicle body.

[0006] In the above-mentioned, a base is provided at the front end of the vehicle body, and a mounting seat is movably connected to the base. The reciprocating cutting device includes a serrated fixed cutter and a movable cutter located on the mounting seat. The movable cutter can reciprocate in the longitudinal direction relative to the fixed cutter, and a cover plate is provided on the mounting seat.

[0007] The driving device mentioned above includes a driving motor, a transmission shaft, a sleeve of the transmission shaft and a working head.

[0008] In the above-mentioned, a driving gear movably connected to the working head shaft is provided in the mounting seat, the driving gear and the driven gear are meshed with each other, fan gears are provided on one side of the driving gear and the driven gear, and a rack for cooperating with the fan gear is provided on the back side of the movable cutter, and the fan gears of the driving gear and the driven gear are alternately meshed with the rack.

[0009] The above-mentioned lifting device includes a telescopic rod movably connected to the four corners of the base, a positioning device is provided on the telescopic rod, the mounting seat is located at the upper end of the telescopic rod, the rotating shaft of the working head is connected with an extension shaft through a coupling, the driving gear is provided with a sleeve that cooperates with the extension shaft, and the two ends of the sleeve are installed on the mounting seat and the cover plate through bearings, and the driving gear and the mounting seat as a whole can move up and down along the extension shaft.

[0010] As mentioned above, keyways are provided along the longitudinal direction on the outer wall of the extension shaft and the inner wall of the sleeve, and the sleeve and the extension shaft are radially limited by a connecting key.

[0011] The above-mentioned vehicle body is motorized or manually pushed.

[0012] As mentioned above, the harvested material collecting device is composed of a bottom plate and a side guard with an opening, and the reciprocating cutting device is located on one side of the opening.

[0013] As mentioned above, the device also includes a pesticide spraying head provided at the upper end of the telescopic rod, the pesticide spraying head is connected to a box provided on the vehicle body, and a liquid pump is provided in the box.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention uses a reciprocating cutting device to harvest, and a harvested material collecting device. During the cutting process, the harvested wheat is blocked by uncut wheat in front and piled up backwards into the harvested material collecting device, thereby achieving the purpose of collection. When the harvested material collecting device is full, it is manually removed, which is convenient for gathering the wheat.

[0015] 2. The fixed cutter is fixed to the mounting base by screws. A fixed column is provided on the fixed cutter, and a waist-shaped hole cooperating with the fixed column is provided on the movable cutter. When the movable cutter moves left and right, it is limited on the fixed column by the waist-shaped hole. A movable cutter limiting column is provided on the upper end of the fixed column.

[0016] 3. The second solution is that when harvesting fireworks, the reciprocating cutting device only needs to be raised by removing the connection between the base and the mounting seat, and then the telescopic rod is installed, and the extension shaft is installed at the same time, and then the mounting seat is installed on the upper end of the telescopic rod. An external thread is provided on the upper outer wall of the telescopic rod, and limit nuts are provided on the upper and lower sides of the mounting seat. At the same time, during the installation process, the shaft sleeve is limitedly connected with the extension shaft, and then the overall installation height of the telescopic rod is adjusted to adapt to the height of cutting fireworks. Then the device can be started to harvest the fireworks, and the harvested fireworks are harvested by the harvesting material collection device.

[0017] 4. The pesticide spray head is connected to a box on the vehicle body, and a liquid pump is provided in the box. In this way, pesticides can be sprayed after the fireworks are harvested to avoid damage to the fireworks due to incisions, which affects the quality of tobacco leaves. Of course, the pesticide spray device can also be used independently of the reciprocating cutting device, and can be used for spraying crops such as tobacco at different times.

[0030] Furthermore, the driving device 3 includes a driving motor 3-1, a transmission shaft, a sleeve 3-2 of the transmission shaft and a working head 3-3. Specifically, a driving gear 8 movably connected to the rotating shaft of the working head 3-3 is provided in the mounting seat 6, and the driving gear 8 is meshed with the driven gear 9. A fan gear 10 is provided on one side of the driving gear 8 and the driven gear 9, and a rack 11 for cooperating with the fan gear 10 is provided on the back side of the movable cutter 2-2. The fan gears 10 of the driving gear 8 and the driven gear 9 are alternately meshed with the rack 11. With such a structure, the movable cutter 2-2 can be meshed in turn through the fan gear 10, thereby realizing the left and right movement of the movable cutter 2-2.

[0031] Example 2 like Figure 4 , Figure 5As shown, this embodiment is based on the embodiment 1. When it is necessary to perform fireworks on tobacco, a lifting device 4 is movably installed. Specifically, the lifting device 4 includes a telescopic rod 4-1 movably connected to the four corners of the base 5. Screw holes are provided at corresponding positions of the telescopic rod 4-1 and the base 5. The telescopic rod 4-1 and the base 5 are connected by bolts and nuts. A positioning device is provided on the telescopic rod 4-1. The positioning device is a screw hole provided on the outer tube of the telescopic rod 4-1. The screw hole is provided with a screw that is mutually fastened with the inner tube of the telescopic rod 4-1. The mounting seat 6 is located at the upper end of the telescopic rod 4-1. The rotating shaft of the working head 3-3 is connected with an extension shaft 4-2 through a coupling. The driving gear 8 is provided with a sleeve 12 that cooperates with the extension shaft 4-2. Both ends of the sleeve 12 are mounted on the telescopic rod 4-1 through bearings.
