Problems solved by technology

The seeds of the air-flow conveying seeder move at high speed in the conveying pipeline, which has strong impact characteristics. If a conventional photoelectric sensor is installed, in addition to the influence of dust, the high-speed moving seeds are easy to collide with the receiving and emitting photodiodes. Cause component wear and affect measurement results

Embodiment Construction

[0047] Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:

[0048] see figure 1 , figure 1 It is a structural schematic diagram of an airflow conveying precision fertilization seeder according to an embodiment of the present invention. The airflow conveying type precision fertilization seeder of the present invention comprises frame 9 and the driver's cab installed on the frame 9, ground wheel 6, seed box 2, seed pipe 1, blower fan 8 and air distribution system 7, also includes Missed-seeding blockage detection device, because the composition, structure, mutual positional relationship, connection relationship, function, and working principle of each part of the air-flow conveying type precision fertilization seeder are relatively mature existing technologies, so it will not be discussed here. To repeat, the following is only a detailed description of the missed broadcast blockage det...

Abstract

The invention discloses a pneumatic conveying type precision combined seed and fertilizer drill, and a miss-seeding and blocking detection method and device thereof. The miss-seeding and blocking detection device includes sowing monitoring units, a forward speed sensor, a speed collecting module and a vehicle controller; the sowing monitoring units are installed on seed metering pipes and includeDoppler microwave sensors, wind pressure sensors and collection processing modules, and the Doppler microwave sensors and the wind pressure sensors are respectively connected to the collection processing modules; the forward speed sensor is installed on a land wheel; the speed collecting module is installed on the land wheel and adjacent to the forward speed sensor; and the vehicle controller is fixed in a driving cab, is connected to a vehicle storage battery to take electricity, and is connected to the sowing monitoring units, the forward speed sensor and the speed collecting module. The miss-seeding and blocking detection method includes collecting a signal of the forward speed sensor to obtain speed information; transmitting the speed information to the vehicle controller in real time;determining, by the vehicle controller, whether the sowing monitoring units enter working states according to the speed information; and performing miss-seeding and blocking detection and alarm sounding during working.

Description

technical field [0001] The invention relates to an on-line monitoring method and device for a precision seeder, in particular to an air-flow conveying type precision fertilization seeder and a method and device for detecting missed seeding blockage. Background technique [0002] Precision seeders play an important role in agricultural production. However, during the operation of the seeder, due to mechanical failures, wet soil in the field, etc., it is easy to cause seed jams, blockage of the seed fertilizer pipe, or emptying of the seed fertilizer box. Agricultural losses. At present, photoelectric sensing detection methods are generally used for seeding monitoring of conventional precision seeders. [0003] As a new type of sowing operation machine, the air-conveyed precision and small amount fertilization seeder has the characteristics of wide operation width, high operation efficiency and high seed utilization rate, and is gradually becoming the development direction o...
