Description

Technical Field

[0001] The utility model relates to the technical field of tobacco field transportation devices, in particular to a fresh tobacco leaf harvesting and transporting machine driven by a single-ditch walking machine. Background Art

[0002] In China and even the world, in the process of tobacco leaf production practice, the harvesting and transportation of fresh tobacco leaves in tobacco fields are basically carried out manually, that is, manual harvesting, and then manually clamping, carrying on shoulders or in arms to transport tobacco leaves out of the tobacco fields; some developed countries, on the premise of having large square pieces of land and using loose leaf baking technology, use large-scale machinery to harvest and transport tobacco leaves. According to incomplete statistics, more than 90% of the fresh tobacco leaves in tobacco fields in the world are harvested and transported by manual harvesting and transportation. There are problems such as labor-intensive, time-consuming, high labor intensity, low efficiency, high cost, and fresh tobacco leaves are easily damaged, which seriously restricts the improvement of tobacco leaf quality and tobacco farmers' reduction of work and cost. How to develop a mechanical device that assists workers in the simultaneous harvesting and transportation of fresh tobacco leaves in tobacco fields is an important research topic to overcome the bottleneck of manual harvesting and transportation of fresh tobacco leaves around the world.

[0003] The prior art discloses a patent with the announcement number CN219087840U, which includes a wheeled walking base, a vertically lifting support platform is provided on the wheeled walking base, and a tobacco leaf storage is provided on the support platform along the moving direction of the vehicle body. The utility model solves the problem that the traditional technology overcomes the small application range of large tobacco leaf harvesting and transportation machinery, which is not conducive to large-scale promotion.

[0004] However, the device is only a field fresh tobacco leaf transporter, and cannot achieve the simultaneous completion of fresh tobacco leaf harvesting and transportation. The fresh tobacco leaf transporters in the prior art gradually exposed the shortcomings of the technology:

[0005] First, the existing crawler harvesting and transporting machines are limited by the mobile structure during the field transfer process, and the moving speed is slow, which affects the harvesting and transportation efficiency between multiple fields.

[0006] Second, existing harvesting and transporting machines need to turn around in the field. During the turning process, they are prone to crushing the surrounding soil, causing the soil to become compacted or crushing plants, which affects the field environment.

[0007] Third, when the device is put into operation in the field, it can only complete the function of transporting fresh tobacco out of the tobacco field instead of manual labor, and cannot realize the harvesting function.

[0008] Fourth, the design of the tobacco rack and tobacco rack of the device is unreasonable. Assuming that only one tobacco rack is set near the control room, a single rack transports 18.75kg of fresh tobacco leaves in a single trip, which is about two rows of 10 meters of tobacco leaves. The carrying capacity is too small, resulting in the need for the device to go back and forth to the tobacco ditch several times, which will damage the tobacco leaves and pose a risk of infectious diseases; if multiple tobacco racks are set, due to the density of tobacco plant rows, it will be difficult for workers to load the far-end tobacco racks except for the ones near the control room. If the far-end tobacco racks are forced to be loaded, many tobacco leaves between the control room and the far-end tobacco racks will be damaged, and the use of this device will not be worth the loss.

[0009] Third, the design of the device did not fully consider the cultivation technology requirements for densely planted tobacco leaves in rows. The workers in the control room moved up and down perpendicular to the direction of the machine's movement. In the process of carrying tobacco leaves up and down the control room, the workers would inevitably damage the dense or even crossed tobacco leaves.

[0010] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0033] Compared with the prior art, the beneficial effects of the utility model are:

[0035] Furthermore, by setting a reversing structure, the tobacco leaf bin can be turned independently without turning the frame, which can effectively overcome the phenomenon of crushing soil and plants due to turning the frame in the prior art, making the tobacco leaf harvesting and transportation process more convenient;

[0036] The invention solves the old production mode that 90% of the fresh tobacco leaves in tobacco fields in the world need to be harvested manually and then transported out of the tobacco fields by manual clamping, shoulder carrying or hugging, etc., by realizing the synchronous completion of harvesting and transportation, and overcomes the problems of high labor intensity and low efficiency in manual harvesting and transportation. The use of the device improves the efficiency by about 300% compared with manual harvesting and transportation. Workers take the driving studio to synchronously harvest and transport tobacco leaves, which greatly reduces the labor intensity of walking back and forth in the tobacco fields. The utility model overcomes the problem that large-scale tobacco leaf harvesting and transportation machinery has a small application range and is not conducive to large-scale promotion. The utility model improves the small tobacco field handling device currently being tried and promoted, and overcomes the problem that the handling machinery only has the function of carrying fresh tobacco leaves and cannot realize the synchronous completion of harvesting and transportation. The utility model improves the work efficiency by about 200% compared with the simple handling small machinery.

[0037] The hydraulic scissor lifter drives the supporting platform to rise or fall as a whole, driving the driving studio and the tobacco-carrying warehouse to rise and fall synchronously, thus realizing the picking of tobacco leaves at different heights, which is convenient for use.

[0038] The straddle-type driving studio enables the worker's face to face the front of the vehicle body, so that tobacco leaves on both sides of the tobacco ridge can be picked at the same time, eliminating the need for a single tobacco ridge to go back and forth, thus improving work efficiency;

[0039] The upper, middle and lower tobacco bins are used to achieve three times the harvesting and transportation volume of a single vehicle. The load-bearing tobacco bin includes a lower tobacco bin fixed on the supporting platform, and the lower tobacco bin is also stacked with an upper tobacco bin and a middle tobacco bin from top to bottom. The upper tobacco bin and the middle tobacco bin are also electrically controlled to extend and retract, and they slide out to the front of the vehicle body in sequence or retract in sequence to be arranged directly above the lower tobacco bin, ensuring that the harvested tobacco can be placed at a remote end without the workers getting on and off the vehicle.

[0040] The upper tobacco leaf bin and the middle tobacco leaf bin are synchronously arranged to slide in sequence toward the front of the vehicle body, so that when the upper tobacco leaf bin is full of tobacco leaves, the winding roller rotates, and the traction rope is used to pull the upper tobacco leaf bin forward to expose the middle tobacco leaf bin. Then, when the middle tobacco leaf bin is full of tobacco leaves, the winding roller rotates, and the traction rope is used to continue to pull the upper tobacco leaf bin forward. After the traction rope between the upper tobacco leaf bin and the middle tobacco leaf bin is gradually tightened, the middle tobacco leaf bin is driven to move forward until the lower tobacco leaf bin is exposed. Then, tobacco leaves are picked and placed in the lower tobacco leaf bin until it is full, thereby increasing the single fresh tobacco leaf harvesting and transportation volume by 300%, and the vehicle body is moved to the field to unload the tobacco, and the cycle is repeated in sequence.

[0041] The upper and middle tobacco warehouses are pushed horizontally to increase the tobacco transport capacity of a single vehicle by 300%;

[0042] Simplify the follow-up components and reduce the occurrence of failures during the working process; improve the stability during the working process; fewer components, simple process, and low failure rate; simple structure and long service life; simple operation and control, easy to manufacture and install on a large scale, and wide range of applications.
