Description
Technical Field
The utility model relates to a novel cotton picking device, in particular to a cotton conveying system which utilizes positive and negative pressure airflow to generate an eddy current field.
Background
Xinjiang is a big province for cotton production, and the cotton production has important influence on the development of industries such as agriculture, textile industry and the like. With the continuous rising of labor cost, the scarcity of labor resources and the development of intensive agriculture in recent years, the demand of cotton pickers by Xinjiang cotton farmers is continuously expanded, mechanical cotton picking becomes the direction of the cotton production development in the world, a cotton conveying system adopted by the cotton pickers in the market at present is only a single fan, and the negative pressure generated by the fan is utilized to convey the unginned cotton. The seed cotton cannot be conveyed in time, so that the picking head is frequently blocked by the seed cotton, particularly in uneven cotton fields with large dew in the morning and evening, the seed cotton cannot be absorbed and blown at high strength, the picking speed is seriously influenced, the falling rate of the seed cotton cannot be effectively controlled, and the requirement of farmers on high-efficiency cotton picking cannot be met.
Disclosure of Invention
The utility model discloses aim at: the double positive and negative pressure soft object sucking and conveying device is provided to solve the problems of blockage of the cotton picking head, low picking speed under the condition of poor working condition, uncontrollable seed cotton falling rate, low picking efficiency and the like in the background.
The utility model relates to a defeated device is inhaled to two positive negative pressure formula soft things, include: a double positive and negative pressure soft material suction and transportation device is composed of positive pressure fan, negative pressure fan, suction inlet, output port, belt pulley, support frame, connecting pipe and bolt. The positive pressure fan and the negative pressure fan are fastened on the supporting frame through bolts, the supporting frame is welded on a cotton picker frame, the suction inlet and the connecting pipe are connected to the suction inlet of the negative pressure fan through bolts, the connecting pipe is mounted above the soft object collecting system through bolts, the output port and the connecting pipe are connected to the outlet of the negative pressure fan through bolts, the blowing port of the positive pressure fan is connected to the lower portion of the soft object collecting system through the connecting pipe, and the belt pulley is connected with the transmission shaft.
When the cotton picker works, the hydraulic motor drives the positive pressure fan and the negative pressure fan to work, the negative pressure fan forms a negative pressure flow field on the upper portion of the soft material collecting system, meanwhile, the positive pressure fan generates a positive pressure airflow field below the soft material collecting system, seed cotton collected by the soft material collecting system is conveyed to the outlet portion of the negative pressure fan through pressure difference generated by the positive pressure flow field and the negative pressure flow field, and then the seed cotton is smoothly conveyed out of the fan to the soft material collecting box through the positive pressure flow field at the outlet portion of the negative pressure fan.
Compared with the prior art: the utility model discloses a malleation fan and negative-pressure air fan coexistence device, very big reduction the jam probability of picking head, improved the fan to the transport rate of unginned cotton, improved cotton picker's picking speed, fan quantity can increase or reduce according to actual demand simultaneously, and the efficiency of falling to the ground of control unginned cotton effectively has satisfied the demand of peasant to cotton high efficiency results.

Detailed Description
As shown in fig. 1 to 5, for the utility model relates to a soft thing of two positive negative pressure formula is inhaled defeated device, include: the utility model provides a by positive pressure fan 4, negative pressure fan 1, sunction inlet 7, delivery outlet 3, belt pulley 2, support frame 6, connecting pipe 5, transmission shaft 8, spare part such as bolt constitute. The negative pressure fan 1 and the positive pressure fan 4 are fastened on the support frame 6 through bolts, the support frame 6 is welded on a frame of the cotton picker, the suction inlet 7 and the connecting pipe 5 are connected to the suction inlet of the negative pressure fan 1 through bolts, the connecting pipe is mounted above the soft object collecting system 9 through bolts, the output port 3 and the connecting pipe 5 are connected to the outlet 12 of the negative pressure fan through bolts, the blowing port 15 of the positive pressure fan is connected to the lower portion of the soft object collecting system 9 through the connecting pipe 5, and the belt pulley 2 is connected with the transmission shaft 8.
As shown in fig. 1, further, the positive pressure fan 4 and the negative pressure fan 1 have their impellers 14 mounted on the same drive shaft 8.
In the operation process of the equipment, the driving force generated by the power source drives the belt pulley 2 to rotate, the belt pulley 2 transmits the driving force to the transmission shaft 8, when the transmission shaft 8 drives the impellers 14 of the negative pressure fan 1 and the positive pressure fan 4 to simultaneously operate, the negative pressure fan 1 forms a negative pressure area above the inner space of the soft object acquisition system 9 through the connecting pipe 5, and the positive pressure fan 4 forms a positive pressure area below the inner space of the soft object acquisition system 9 through the connecting pipe 5. The soft object collected by the soft object collecting system 9 is output to the suction inlet 7 by vortex airflow generated by the pressure difference of the positive and negative pressure areas, and then the soft object enters the negative pressure fan through the connecting pipe 5 connected with the negative pressure fan 1. The soft material entering the negative pressure fan 1 is conveyed to the output port 3 under the combined action of the impeller 14 and the air flow, and finally conveyed to the soft material collecting box 10.
