[0012] Figure 2 It is a schematic diagram of the internal structure of the seed box.
[0013] Figure 3 It is a structural schematic diagram of the seed hole. DETAILED DESCRIPTION
[0014] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate the understanding of technicians.
[0015] like Figure 1-3As shown, the utility model provides a broad bean planting seeding device, including a seeding box 1 and a seeding disk 2. A circular accommodating chamber is arranged in the seeding box 1, and the seeding disk 2 is rotatably installed on the bottom of the accommodating chamber through a rotating shaft 3 arranged in the middle through a bearing, and a motor 4 is installed on the top of the seeding box 1 and is transmission-connected with the rotating shaft 3 of the seeding disk 2; annular seed storage holes 5 are evenly opened on the edge of the seeding disk 2; a main seed scraping plate 6 which divides the accommodating chamber into a left chamber and a right chamber is arranged on the inner wall of the seeding box 1, two pre-seed scraping plates 7 are arranged on the side wall of the left chamber, and seeding holes 8 are arranged on the bottom of the right chamber. The broad bean seeds are located in the left chamber, and the motor 4 drives the seed plate 2 to rotate, so that the broad bean seeds fall into the seed storage holes 5. The broad beans on the seed storage holes 5 are scraped by the pre-scraping plate 7 to make the seeds in the seed storage holes 5 flat. One seed storage hole 5 can only store one seed to prevent the situation of multiple seeds in one empty hole. Through the arrangement of two pre-scraping plates 7 and the main scraping plate 6, the seeds on the seed storage holes 5 are scraped multiple times, so that the seed storage holes 5 with empty spaces are convenient for seeds to fall into, and it is prevented that when there are many seeds, they are piled up and squeezed, and support each other so that the seeds cannot fall into the seed storage holes 5, thereby preventing the situation of empty spaces for seeds; the broad bean seeds stored in the seed storage holes 5 rotate to the right chamber with the seed plate 2, and when they reach the seed storage holes 8, they are discharged from the seed storage holes 8 in sequence, so that the seeds are evenly distributed.
[0016] like Figure 2 As shown, a sleeve 9 sleeved outside the rotating shaft 3 is provided on the top of the accommodating chamber, and the main scraping plate 6 is installed between the side wall of the accommodating chamber and the sleeve 9. The main scraping plate 6 is connected to the sleeve 9, which does not affect the rotation of the rotating shaft 3 and can separate the accommodating chamber.
[0017] like Figure 2 As shown, the left chamber is provided with a semi-conical guide block 10 installed on the side wall of the main seed scraper plate 6. When the broad bean seeds are placed in the left chamber, they are accumulated on the guide block 10 and can slide downward to the seed storage hole 5 with the rotation of the seeding disc 2, so as to avoid the seeds being accumulated on the horizontal seeding disc 2 and unable to automatically move to the seed storage hole 5 at the edge of the seeding disc 2, causing the broad bean seeds to be retained.
[0018] The bottom of the seeding hole 8 is connected with a seeding tube 11. After being discharged from the seeding hole 8, the broad bean seeds enter the seeding tube 11, roll down along the seeding tube 11 and fall into the groove of the land, so that the broad beans are sown neatly.
[0019] The top of the left chamber is provided with a feed port 12 for adding broad bean seeds. The feed port 12 is convenient for adding broad bean seeds into the left chamber in the seeding box 1, thereby carrying out the seeding operation of broad beans.
[0020] Working process:
[0021] Broad bean seeds are added into the left chamber of the accommodating chamber through the feed port 12, and the motor 4 is started to drive the seed plate 2 to rotate, so that the broad bean seeds fall into the seed storage holes 5, and the seeds on the broad beans in the seed storage holes 5 are scraped by the pre-scraping plate 7 to make the seeds in the seed storage holes 5 flat. One seed storage hole 5 can only store one seed to prevent the situation of multiple grains in one empty hole. Through the arrangement of two pre-scraping plates 7 and the main scraping plate 6, the seeds on the seed storage holes 5 are scraped multiple times, so that the seed storage holes 5 with vacancies are convenient for seeds to fall into, and it is prevented that when there are many seeds, they are piled up and squeezed, and support each other so that the seeds cannot fall into the seed storage holes 5, thereby preventing the situation of vacancies in the seeds; the broad bean seeds stored in the seed storage holes 5 rotate to the right chamber with the seed plate 2, and when they reach the seed storage holes 8, they are discharged from the seed storage holes 8 in sequence, enter the seed storage pipe 11, roll down along the seed storage pipe 11 and fall into the groove of the land, so that the seeds are evenly discharged.
[0022] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
