[0013] A sorting head of a planter, which is arranged in the center of the sorting conduit, is characterized in that: the lower part of the sorting head is set as a sorting cone 5, and the center of the bottom surface of the sorting cone 5 is provided with a screw thread Holes 6 and threaded holes 6 are connected to the DC motor that provides power for the sorting head. The upper part of the sorting cone 5 is provided with a cylindrical sorting body 4, and the upper surface of the cylindrical sorting body 4 is a secondary sorting contact plane. 1. There is a conical-top round rod 2 in the center of the second-level sorting contact plane 1, and the seed tube 7 is set on the top of the cone-top round rod 2. Two symmetrical sorting protrusions are set on the second-level sorting contact plane 1. platform, the two sorting planes 3 of each sorting boss are perpendicular to the contact plane 1 of the secondary sorting. The seeding end of the seeding pipe 7 shrinks gradually. The ax...

Abstract

The invention relates to a seed dividing head of a planter, which is arranged in the centre of a seed dividing conduit. The lower part of the seed dividing head is provided with a seed dividing frustum. The centre at the bottom of the seed dividing frustum is provided with a screwed hole, and the screwed hole is connected with a direct current electric motor of which the power is provided by the seed dividing head. The upper part of the seed dividing frustum is provided with a cylindrical seed dividing body. The upper surface of the seed dividing body is provided with a secondary seed dividing touch plane, and the centre of the secondary seed dividing touch plane is provided with a cone round rod. A seed ranking tube is sleeved at the top of the cone round rod. The secondary seed dividingtouch plane is provided with two symmetrical seed dividing bosses, and both seed dividing planes of each seed dividing boss are perpendicular to the secondary seed dividing touch plane. In the invention, the cone and a section plate form a first-class seed dividing structure, and the cone round rod and the seed dividing touch planes surrounding the cone round rod form the secondary seed dividing structure. The invention improves the uniformity and the stability of seed division and changes the vibration caused by the gravity centre shift of the traditional seed dividing head. The accuracy andthe scientific performance of the contrast test research in small area fields are improved.

Description

technical field [0001] The invention belongs to the field of agricultural machinery and equipment, and in particular relates to a device capable of completing two sorting work in the sowing link of a plot seeder. Background technique [0002] According to the situation and characteristics of China's agriculture, the Ministry of Agriculture clearly stated at the "National Agricultural Seed Work Conference" in September 1995 that "create a seed project and promote agriculture to a new level", which provided opportunities for the development of community seeders and also provided opportunities for the community to sow seeds. The development of the planter has brought huge challenges, and the requirements for the test impact caused by the seeding error of the plot planter have become more and more stringent, and this has put forward higher requirements for the seeding device of the plot planter. At present, there are various types of seeding heads for plot seeders, but all of th...
