Description
Technical Field
The invention belongs to agricultural machinery, and mainly relates to a seed sowing device for rice hole direct seeding operation.
Background
Rice transplanting operation, rice seedling throwing operation and direct seeding operation of rice crops are traditional operation modes which exist in rice planting modes for many years and continue to the present, and the three modes can meet and adapt to the requirements of different conditions and are used in different regions. In recent years, along with the mass transfer of agricultural labor to cities, the agricultural labor is seriously lacked, and the seedling transplanting or throwing method after rice seedling raising, which has the advantages of large workload, long operation period and high production cost, is gradually replaced by a direct rice seeding operation mode with small labor amount, low labor intensity, short operation period, high operation efficiency and low production cost in certain areas. However, at present, a special seed sowing device capable of meeting and adapting to paddy hole direct sowing is still blank, only a dry field crop seed sowing device can be used for paddy hole direct sowing operation, the operation effect and quality can not be guaranteed, and the efficiency is low.
Disclosure of Invention
The invention aims to solve the problems in the prior art, and researches and designs a disc-shaped end face cam-driven type rice hole direct-seeding seed sowing device by combining the actual requirements of rice direct-seeding production operation, so that the purposes of fully meeting and adapting to the use requirements of rice hole direct-seeding operation, good operation quality and high efficiency are achieved.
The purpose of the invention is realized as follows: the disc-shaped end face cam driven type rice hole direct seeding seed sowing device comprises a shell, a seed conveying pipe and a duckbilled seed taking and sowing assembly, wherein the seed conveying pipe is communicated with the inside of the shell, a disc-shaped end face cam is fixedly arranged on the inner wall surface of the top wall of the shell, a rotary driving shaft penetrates through the central part of the disc-shaped end face cam and is assembled on the top wall of the shell, a seat plate is fixedly arranged at the lower end part of the rotary driving shaft, the seat plate is positioned at the lower part of the disc-shaped end face cam, N duckbilled seed taking and sowing assemblies are uniformly assembled on the seat plate along the circumferential direction, the upper end parts of upper and lower telescopic duckbilled opening and closing driving rods of the N duckbilled seed taking and sowing assemblies are in contact fit with the disc-shaped end face cam, a pressure spring is sleeved on the upper and lower telescopic duckbilled opening and closing driving rods, the upper end part, the housing room is disposed below the seat plate side.
The invention has novel, simple and reasonable structure, good quality and effect of rice hole direct seeding operation, high operation efficiency, reliable use, less faults and strong specificity, can particularly adapt to and meet the row application requirement of multiple rice seeds at one time of rice hole direct seeding, and provides excellent technical equipment for large-area popularization and application of rice crop hole direct seeding agricultural technology.

FIG. 1 is a general structural schematic diagram of a disc-shaped end face cam driven rice hole direct seeding seed sowing device.
Description of part numbers in the figures:
1. the device comprises a shell, a seed conveying pipe, a seed seat plate, a duckbilled seed taking and discharging assembly, a seed feeding chamber, a duckbilled opening and closing driving rod, a duckbilled.
Detailed Description
The following detailed description of the inventive embodiments is provided in connection with the accompanying drawings. A disc-shaped end face cam driven type rice hole direct seeding seed sowing device comprises a shell 1, a seed conveying pipe 2 and a duckbilled seed taking and sowing assembly 4, wherein the seed conveying pipe 2 is communicated with the inside of the shell 1, a disc-shaped end face cam 7 is fixedly arranged on the inner wall surface of the top wall of the shell 1, a rotary driving shaft 8 penetrates through the central part of the disc-shaped end face cam 7 to be assembled on the top wall of the shell 1, a seat plate 3 is fixedly arranged on the lower end part of the rotary driving shaft 8, the seat plate 3 is arranged at the lower part of the disc-shaped end face cam 7, N duckbilled seed taking and sowing assemblies 4 are uniformly assembled on the seat plate 3 along the circumferential direction, the upper end parts of upper and lower telescopic duckbilled opening and closing driving rods 6 of the N duckbilled seed taking and sowing assemblies 4 are in contact fit with the disc-shaped end face cam 7, a pressure spring 9 is sleeved on the upper and lower telescopic duckbilled opening and closing driving rods 6, the lower end part of the pressure spring 9 is in extrusion contact with the seat plate 3, and the throwing chamber 5 is arranged below the side of the seat plate 3.
When the rice seed feeding device is used in operation, rice seeds are fed into the inner bottom of the shell 1 from the seed feeding pipe 2, the rotary driving shaft 8 drives the N duckbilled seed taking and discharging assemblies 4 to do circumferential overall rotary motion through the seat plate 3, under the matched control of the disk-shaped end face cam 7 and the pressure spring 9, the upper and lower telescopic duckbill opening and closing driving rods 6 of the duckbilled seed taking and discharging assemblies 4 perform upper and lower telescopic motion, duckbill opening and closing alternate switching motion of the duckbilled seed taking and discharging assemblies 4 is achieved, when the duckbilled seed taking and discharging assemblies are opened, seed taking operation from the inner bottom of the shell 1 is firstly completed, then the duckbilled seed taking and discharging device rotates to the upper side of the seed throwing chamber 5 in a closed state, the duckbilled seed is opened again, the rice seeds are discharged into the seed throwing chamber 5, the taking and discharging operation process of the duckbilled seed taking and discharging assemblies 4 is.
