Description
Technical Field
The utility model relates to a suction-blowing seed cotton conveying device, and belongs to the technical field of cotton mechanized harvesting.
Background
Currently, cotton mechanized harvesting technologies representing the world's advanced level are johndil (DEER) and kesi (CASE) in the united states, and their models are largely classified into harvest-type models and harvest-type models. On the basis of advanced technology of digestion and absorption abroad, the horizontal spindle cotton picker is demonstrated and popularized in partial areas in China, and has the advantages of high production efficiency, low impurity content and the like; however, the production and use costs are too high, and the method is not suitable for cotton varieties with high plants, low density and high yield and planting agronomy in some areas, and is difficult to popularize in a large area in the whole country. The system-collecting type represented by a brush roller type cotton picker, a finger brush type cotton picker and the like has the advantages of wide application range, low production, use and maintenance cost, high clean rate and higher cost performance; however, cotton boll, boll shell and seed cotton can be picked together in the cotton picking process, and pretreatment links such as airborne clear boll, clear boll shell and clear broken leaves are added subsequently, so that cotton fibers can be damaged to a certain extent.
According to the knowledge of the applicant, the picking technology of the current self-propelled air suction cotton picker mainly relies on mechanical and wind power to assist in picking, the strong negative pressure formed by the high-speed fan extends to a picking part to assist in picking open cotton on cotton stalks, the cotton is conveyed into the fan through a conveying pipeline, and seed cotton is sent into a cotton box through the combination of centrifugal force of blades and positive pressure of wind power. In the working practice, the applicant finds that the blade channels of the centrifugal fan are narrow, and if a small amount of cotton branches or agglomerated seed cotton enters, the channels are easy to be blocked; on the other hand, the seed cotton seeds which are hit by the fan blades are damaged in a small amount, and the quality of the seed cotton seeds and the subsequent cotton ginning process are affected.
The Chinese patent application No. 201420224961.6 discloses a cotton boll separating and conveying device. The device is arranged at a seed cotton outlet of a picking platform, a cotton picking roller picks up seed cotton flow, positive pressure wind power and gravity are utilized to layer seed cotton and cotton bolls, cotton bolls at the lower layer enter a cotton boll recycling system through a boll discharging port, and finally are sent to a boll collecting box. However, when the recovery amount of cotton bolls is large, positive pressure drainage wind is easy to form at the boll discharge port, and part of seed cotton is directly sent out from the boll discharge port, so that the loss of seed cotton is caused.
Therefore, the Chinese patent with the application number of 20151230608. X creates a high-efficiency low-loss seed cotton peach cleaning and conveying device, negative pressure suction separation is used for replacing positive pressure winnowing, so that the loss of seed cotton is obviously reduced, and the cotton boll recovery rate is improved. However, the uneven ground surface sometimes causes a hilling phenomenon when the picking speed is too low in the picking process of the cotton picker, and immature stiff fruits cannot be separated and mixed into a subsequent airborne pretreatment machine, so that adverse effects on seed cotton dyeing, seed cotton quality reduction, impurity removal efficiency and the like can be generated.
The Chinese patent application No. 201720946857.1 discloses a multi-stage seed cotton heavy impurity separating device, which forms a three-stage heavy impurity sequential separating system and can be applied to seed cotton conveying of a collecting cotton picker. However, due to the fact that the negative pressure generated by the siphon principle is small, the air flow is small, and the like, the device is not suitable for conveying seed cotton for assisting in picking the seed cotton.
In summary, for self-propelled air-aspiration picking techniques, there is currently no suitable seed cotton conveying device for pneumatically assisted picking.
