Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the intended purpose of the present invention, the following detailed description is given to the embodiments, structures, features and effects according to the present invention with reference to the accompanying drawings and preferred embodiments as follows:

the application has the advantages that a small number of seeds are manually thrown from the upper side, the seeds are discretely distributed to the upper side of the quadrangular pyramid, the equal distribution of the four conical surface seeds is formed, the seeds slide down to the seed distributing pipes along the conical surfaces, every two diagonally arranged seed distributing pipes are collected to the three-way pipe, and the seeds are collected through the three-way pipe and fall into the seed distributing pipes. Through the seed falling pipe of diagonal switch-on, the inhomogeneity of seed when following the conical surface gliding to in the seed sorting pipe can be reduced, the broadcast precision of two sets of seeds is improved.

A four-pyramid seed divider is shown in figures 1 to 3 and comprises a four-pyramid 1, a seed dividing grid plate 2, four seed dividing pipes 3, two three-way pipes 4 and two seed falling pipes 5.

The top of the quadrangular pyramid 1 faces upwards, the quadrangular pyramid 1 is arranged in an inner cavity with an upward opening of the seed separating grid plate 2, the inner cavity of the seed separating grid plate 2 is uniformly divided into four sub-cavities by the quadrangular pyramid 1, the bottom ends of the sub-cavities are provided with openings, and the sub-cavities are used for collecting seeds scattered on each conical surface and sliding down and guiding the seeds to fall into the three-way pipe 4. Seeds such as corns fall off from the conical top of the quadrangular pyramid 1, then the seeds are scattered on four surfaces of the quadrangular pyramid 1 under the action of the quadrangular pyramid 1, and slide downwards along the conical surface by means of gravity, and are dispersed and slide into the four sub-cavities. Preferably, the edges of the quadrangular pyramid 1 are rounded to prevent the seeds from being hindered from falling. Here, as shown in fig. 2, four ribs 6 are uniformly distributed in the seed separating grid 2, the ribs 6 are in contact with the conical line of the quadrangular pyramid 1, and the upper part of the ribs 6 is a round edge to prevent the seeds from falling.

The top ends of the seed distributing pipes 3 are communicated with the openings of the seed distributing grid plates 2 respectively, and the top end of each three-way pipe 4 is communicated with the bottom ends of the two seed distributing pipes 3 which are arranged diagonally. The seeds dropped from the seed distributing pipe 3 cross into the three-way pipe 4, and the three-way pipe 4 plays a role in collecting the seeds.

The top end of the seed dropping pipe 5 is communicated with the bottom end of the three-way pipe 4 respectively, the bottom end of the seed dropping pipe 5 is connected with the seed sowing device, and the seed dropping pipe 5 is a hose and used for collecting and conveying seeds.

The equalizing funnel for manual seed throwing is used in cooperation with the equalizing funnel shown in fig. 4 and 5, and comprises a leakage body 7, a seed dropping pipe 8 and an equalizing cone 9.

As shown in fig. 4 and 5, a seed dropping opening is arranged at the bottom end of the leakage body 7, and the top end of the seed dropping pipe 8 is communicated with the seed dropping opening of the leakage body 7. In this embodiment, the drain body 7 is a rectangular drain body, and may be a conical drain body.

Referring to fig. 5 again, the equipartition cone 9 includes a main cone 91 and four rib plates 92, the main cone 91 and the rib plates 92 are uniformly scattered, the outer ends of the rib plates 92 are connected with the inner wall of the seed dropping pipe 8, the equipartition cone 9 is arranged above 3cm of the opening at the bottom end of the seed dropping pipe 8, namely, the connection position of the rib plates 92 and the seed dropping pipe 8 is located at the position 3cm upward from the bottom of the seed dropping pipe 8. Here, the seeding tube 8 is a seamless steel tube with an inner diameter of 4.5cm and a wall thickness of 2mm, and the leak body 7 and the seeding tube 8 can be connected by welding. The design of the equalizing cone 9 not only can increase the seed throwing uniformity, but also can make the subsequent seeding more accurate. Preferably, the top edge of the rib 92 forms an angle of 120 ° with the side edge of the main cone 91, so that the seeds are better dispersed during the falling process.

When using, pour the seed into hourglass body 7, the seed is divided into four parts under the effect of the cone 9 is equallyd divide to seed falling 8 inside, then falls into four pyramid and divides kind of a ware in, is dispersed once more to through twice separation effect, play the effect of evenly allocating with the seed.

Each part has in this application and equally divides, and not this part really can play the equipartition effect, but under the combined action of each part, plays the homogeneity of falling kind.

The invention has been described above with reference to a preferred embodiment, but the scope of protection of the invention is not limited thereto, and various modifications can be made and equivalents can be substituted for elements thereof without departing from the scope of the invention, and features mentioned in the various embodiments can be combined in any way as long as there is no structural conflict, and any reference sign in the claims should not be construed as limiting the claim concerned, and the embodiments should be regarded as being exemplary and non-limiting in any way whatsoever. Therefore, all technical solutions that fall within the scope of the claims are within the scope of the present invention.
