Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco field planting, and in particular relates to a tobacco leaf field harvesting and transportation device. Background Art

[0002] The leaves of flue-cured tobacco are divided into upper leaves, middle leaves and lower leaves according to the growth position. Due to the different material accumulation and light exposure time in different parts, the time of maturity and harvesting is also quite different. The existing technology basically adopts manual batch harvesting. Before harvesting, tobacco farmers first drive the vehicle to the field, and then work according to the tobacco ridge: first break off the tobacco leaves of the tobacco plants in the same tobacco ridge and place them under the tobacco plants (the broken tobacco leaves need to avoid direct sunlight as much as possible, otherwise the excessive dehydration of the tobacco leaves will easily lead to difficulties in later baking and difficult to fix the color). After the tobacco leaves on the same tobacco ridge are broken, the tobacco farmers return and pick up the tobacco leaves in sequence and finally place them on the vehicle. The problems of this operation method are as follows: 1) Due to the limited manual transportation capacity, tobacco farmers often need to carry tobacco leaves on a tobacco ridge repeatedly, and the carrying process is also easy to cause mechanical damage to the leaves, resulting in bleeding or green marks during later baking; 2) The tobacco leaf harvesting period is from the end of June to the end of September, so no matter which part of the tobacco leaves are harvested, they are harvested in a high temperature and strong light environment, resulting in a heavy workload for tobacco farmers.

[0008] Preferably, the air regulating box comprises a cylinder with an adjusting plate assembled through a bearing at one end and sealed by the adjusting plate and the other end sealed by the outer wall of the enclosure frame, and an air dividing plate which radially divides the internal space of the cylinder is provided on the plate surface of the adjusting plate located inside the cylinder.

[0009] Preferably, the air jet pipe, air supply pipe and air blowing pipe are arranged on the cylinder wall in a clockwise manner at an angle of 90°. Specifically, the air jet pipe and the air blowing pipe should be symmetrically arranged relative to the cylinder axis, and the air supply pipe is located between the air jet pipe and the air blowing pipe. In this arrangement, the connection state of the air supply pipe and the air jet pipe or the air blowing pipe can be switched by adjusting the position of the air distribution plate.

[0011] Preferably, a frame rod is provided inside the rolling shutter box, and a spiral spring and a drum are sequentially sleeved on the outside of the frame rod, and two ends of the spiral spring are respectively connected to the outer wall of the frame rod and the inner wall of the drum, the outer wall of the drum is connected to one end of the rolling shutter and winds up the rolling shutter, and the other end of the rolling shutter protrudes from a preset opening on the top surface of the rolling shutter box and is connected to a hanging rod, and a hook for hanging a hanging plate is provided on the rod body of the hanging rod.

[0013] The working process of this utility model is as follows:

[0014] First overcome the elastic force of the scroll spring, pull the roller shutter out of the roller shutter box and around the arc support rod, then use the hook to hang the scraper so that the roller shutter covers the top of the enclosure frame to prevent sunlight from directly shining into the internal space of the enclosure frame.

[0015] When the tobacco growers move between ridges, they pull the trolley with the handle and rotate the adjustment plate to keep the air supply pipe and the air spray pipe connected. The air pump sprays the air through the air supply pipe-air spray pipe-ejector-spray pipe. At the same time, the air flow will generate negative pressure after entering the ejector and suck in the water mist produced by the atomizer through the suction port and finally spray it out from the spray pipe. Therefore, the tobacco growers will be exposed to the humid air flow in front of the trolley, thereby improving the comfort.

[0016] When the tobacco farmer moves to the tobacco plant, he goes around to the back of the trolley and turns the adjustment plate so that the air distribution plate is only connected to the air supply pipe and the air blowing pipe. The air pump sprays the air through the air supply pipe-air blowing pipe-air blowing box. On the one hand, it can cool down the tobacco farmer who bends down to break the leaves, and on the other hand, it can spray the broken leaves to blow away dust, soil residue and other impurities on the leaves. Then the tobacco farmer can put the leaves into the enclosure frame in an orderly manner.
