Problems solved by technology

Disorderly throwing seedlings is simple, but it is difficult to ensure the uniformity of the seedlings in the field. Some parts need to be rearranged manually by farmers, which also brings a lot of inconvenience to later field management and harvest, and causes diseases due to ventilation and other problems.
Orderly throwing seedlings can overcome the disadvantages of disorderly throwing seedlings, but it is difficult to achieve, especially to ensure equal plant spacing; currently no domestic products have entered the market, and foreign products are too complicated

Embodiment Construction

[0011] The present invention will be further described below in conjunction with drawings and embodiments.

[0012] As shown in Fig. 1 and Fig. 2, in the differential speed rebound type orderly seedling throwing device of the present invention, the transmission gear 2 fixed on the main shaft 1 drives the transition gear 3 and the internal gear 4 on the stationary support disc 6 to transmit the motion to The outer drum 7, the middle drum 19 and the inner drum 20 are fixed as a whole through the left and right connecting flanges 5. The three-layer drum is integrated. The cam 18 installed on the main shaft 1 is arranged axially according to a certain phase difference and rotates with the main shaft 1. . On the cylinder wall of the three-layer drum 7, there are several coaxial holes evenly distributed in the circumference and the axial direction. Return spring 9 is housed on the ejector rod 8, and one end of return spring 9 withstands on the shaft shoulder that one end of ejector...

Abstract

A differential resilience type sequential seedling throwing mechanism is disclosed. The external, middle and internal drums fixed together have several coaxial holes arranged uniformly. The push rods with restoring spring are inserted in said holes. A row of cams are arranged on a mainshaft relatively to said push rods. A row of L-shaped levers with torsional restoring spring are installed on main shaft. The rotation of cam can drive said push rod to eject the seedlings in field via guide tube.

Description

technical field [0001] The invention relates to a transplanting machine, in particular to a differential speed rebound type orderly seedling throwing device. Background technique [0002] At present, the rice motor-driven seedling throwing machines sold in the domestic market are divided into disorderly throwing seedlings and orderly throwing seedlings. Disorderly throwing seedlings is simple, but it is difficult to ensure the uniformity of seedlings in the field. Some parts need to be rearranged manually by farmers, which also brings a lot of inconvenience to later field management and harvest, and causes diseases due to ventilation and other problems. Orderly throwing seedlings can overcome the disadvantages of disorderly throwing seedlings, but it is difficult to realize, especially to ensure that the plant spacing is equal; at present, no domestic products have entered the market, and foreign products are too complicated. Contents of the invention [0003] The object ...
