Example Embodiment

[0028] Example one

[0029] This embodiment is a pneumatic conveying and feeding device matched with a full-feed peanut picking combine harvester, and its basic structure is as follows figure 1 Shown: the outlet of the air inlet pipe 1 of the air inlet of the external fan is connected to the inlet ends of the left and right air ducts 5, 3 and the middle blanking pipe 4 through the shunt regulating device 2. The left and right air ducts 5 , 3 are respectively connected to both sides of the middle blanking pipe 4 through the grid plate 15 (see image 3 ), the outlet end of the intermediate blanking pipe 4 is in communication with the feeding pipe 7.

[0030] The specific structure of the shunt control device 2 is as follows figure 2 As shown, it is composed of a reducing pipe 8 and left and right air deflectors 9 and 10 with adjustable diversion angles. The reducing pipe 8 is in the shape of a bell mouth with a gradually expanding diameter, and one end and the upper end of the air de...

Abstract

The invention relates to a pneumatic conveying feeding device, and belongs to the technical field of agricultural machines. An outlet of an air inlet pipe of the device communicates with the inlet ends of a left air guide pipe, a right air guide pipe and a middle blanking pipe through a flow dividing regulating device, the inner sides of the left air guide pipe and the right air guide pipe are communicated with the two sides of the middle blanking pipe through grating plates, the outlet end of the middle blanking pipe is communicated with a feeding pipe, the flow dividing regulating device iscomposed of a reducer pipe, a left air guide plate with adjustable flow dividing inclination and a right air guide plate with adjustable flow dividing inclination, the inner side of the left air guidepipe and the inner side of the right air guide pipe are provided with air outlets with the grating plates, and guide air channels are formed between the inlet ends of the left air guide pipe and theright air guide pipe and the air outlets; feeding openings are formed in the upper portion of the middle blanking pipe, a moving wheel is arranged in the middle of each feeding opening, and triangularcross section flow dividing blocks with upward top corners are arranged on the front portion and the rear portion of each feeding opening. The pneumatic conveying feeding device is ingenious in design, compact in structure, simple in structure, rpaid and convenient to assemble, convenient to clean, smooth in work, suitable for pneumatic conveying of most particle materials including peanuts and particularly suitable for material conveying of a movable combined harvesting device.

Description

technical field [0001] The invention relates to a pneumatic conveying and feeding device, in particular to an anti-blocking and anti-winding pneumatic conveying and feeding device, which belongs to the technical field of agricultural machinery. Background technique [0002] The pneumatic conveying feeding device is mainly matched with the full-feeding peanut picking combine harvester. The picking-type combined harvesting equipment can complete the combined harvesting operations such as peanut picking, fruit picking, cleaning, transportation, and fruit collection at one time. Fruit box. Therefore, the pneumatic conveying feeding device is the main component of the full-feeding peanut combine harvesting equipment. The high failure rate of the existing pneumatic conveying feeding device is one of the main reasons restricting the development of combined harvesting equipment. There are four major problems: First, the long broken branches and seedlings and residual film are easi...
