Self-propelled air suction comb tooth type lycium barbarum picking harvester

Abstract

The invention provides a self-propelled air suction comb tooth type lycium barbarum picking harvester which comprises a trolley, a gasoline engine generator, a comb tooth picking device and a collecting box. A thrust handle is mounted on a frame, walking land wheels are arranged on the same end face with the thrust handle, and a steering wheel is arranged on the other end face. The gasoline engine generator and the collecting box are arranged on a platform, a sorting screen and a two-channel fan are arranged in the collecting box, and the gasoline engine generator provides a power source for a motor and the fan. The comb tooth picking device comprises a picking comb and a picking comb motor, and an induced draft fan is arranged at the end, close to the comb tooth picking device, of a conveying bag. A movable handle is held in hands to enable the comb tooth picking device to press close to lycium barbarum branches, the induced draft fan sucks air to enable lycium barbarum fruit stems to be changed to deviate from a plumb line and form an included angle of 30-90 degrees with the plumb line from being in a plumb line state, the picking comb motor drives the picking comb to rotate, lycium barbarum fruits fall off from the branches to enter the conveying bag and then enter a strip rod, and the lycium barbarum fruits drop into the collecting box after being sorted by the fan.

Description

technical field [0001] The invention provides a self-propelled air-suction comb-tooth type wolfberry picking harvester, which belongs to the technical field of agricultural machinery. Background technique [0002] Lycium barbarum is a characteristic economic crop in Ningxia, with a planting area of ​​200,000 mu. It is a fruit that can be used for both food and medicine. It is rich in nutrients, rich in protein and vitamins, and has the effect of lowering blood pressure and lipids. [0003] Lycium barbarum has a short picking period, and it must be picked immediately when it turns from green to red. Picking too late will reduce the commodity value of wolfberry and cause economic losses due to perishability. [0004] Manual picking requires a lot of labor, and wolfberry matures seasonally. With the continuous expansion of the planting area and labor shortage, manual picking is difficult to meet the requirements of the planting area. Mechanical picking is the general trend. The...

AI Technical Summary

Problems solved by technology

[0003] The picking period of wolfberry is short, and it must be picked immediately when it turns from green to red. If picking is too late, the commodity value of wolfberry will be reduced, and it will be perishable and cause economic losses.

[0004] Manual picking requires a lot of labor, and wolfberry matures seasonally. With the continuous expansion of the planting area and labor shortage, manual picking is difficult to meet the requirements of the planting area. Mechanical picking is the general trend. The stems of wolfberry are growing on the branches, and the stems are connected. Fruits, drooping fruits, low efficiency and high cost of hand-pick picking. In addition, the plants of wolfberry grow in the open air, and a lot of dust is attached to the leaves. The dust from manual picking enters the body through the respiratory tract, which seriously damages the body

[0005] Patent 200910077547.0 is an electric tool for air suction picking. The battery voltage is less than 48V. It is difficult to drive a high-power fan with DC voltage. In addition, the stem of wolfberry has a certain toughness, so it is difficult to pick by air suction alone. The weight of the battery is the same as the weight of wolfberry. It is unbearable to work for a long time manually; the patent 201010211242.7 uses a hob to pick wolfberries. Since wolfberries grow on branches, there are a lot of wolfberries on the fruit handles, and the fruits of wolfberries droop. Picking wolfberries with hobs is easy to damage wolfberries, and the picking is not thorough.
