Detailed Description

As shown in fig. 1 to 9, the present invention mainly includes a fixed plate 1, a bearing 2, a main baffle 3, and an auxiliary baffle 4, and the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 to 3, the fixing plates 1 are two circular metal plates and are arranged in parallel, one of the fixing plates is provided with a seed inlet 11, the main baffle 3 is a circular metal piece, the two fixing plates are arranged on the inner side of the main baffle, a bearing 2 is arranged between the main baffle and the fixing plates, the fixing plates and the main baffle are rotatably connected through the bearing, and at the moment, the main baffle, the bearing and the fixing plates are connected into a whole. Enclose into between main baffle, bearing, the fixed plate and store up kind of chamber, be equipped with a plurality of first holes 31 that are located the collinear on main baffle, first hole is the round hole. The outer side of the main baffle is provided with an auxiliary baffle 4 which is also a circular ring-shaped metal piece, the auxiliary baffle is provided with a plurality of second outlet holes 41 which are positioned on the same straight line, and the diameter of the first outlet hole is larger than that of the second outlet hole. The auxiliary baffle and the main baffle are relatively fixed along the circumferential direction, and the first outlet hole and the second outlet hole are coaxially arranged. The auxiliary baffle plate and the main baffle plate can be connected through threads, as shown in figure 4, when the seeding box is used, the whole seeding box rotates, and when the first outlet hole and the second outlet hole rotate to the lowest point, the seeds 5 in the seed storage cavity fall through the first outlet hole and the second outlet hole.

In order to realize the relative fixation between the main baffle and the auxiliary baffle along the circumferential direction, the outer wall of the main baffle is provided with a slide block arranged along the bus direction, and the inner wall of the auxiliary baffle is provided with a slide groove matched with the slide block.

As shown in fig. 5, the adjusting device further includes an adjusting unit, the adjusting unit of the first embodiment includes a fixing ring 6 fixed on the outer wall of the auxiliary baffle, a pair of supports 7 arranged above the auxiliary baffle, a screw 71 rotatably installed between the two supports, a motor 72 fixed on one of the supports, a screw nut 73 arranged on the screw, and a shift lever 74 fixed at the bottom of the screw nut, under the action of the motor, the screw is driven to rotate, and further the screw nut is driven to move left and right, a circular groove 61 is arranged on the cylindrical outer wall of the fixing ring, a first end of the shift lever is fixedly connected with the screw nut, and a second end of the shift lever extends into the circular groove. When the screw nut moves left and right, the driving rod is driven to move left and right, the fixing ring is further stirred to move left and right, and the auxiliary baffle is further stirred to move along the axial direction of the main baffle. At the moment, the auxiliary baffle plate is connected with the main baffle plate in a sliding mode along the axial direction. As shown in fig. 6, when the driving lever drives the auxiliary baffle to move along the axial direction for a certain length, the first outlet and the second outlet are staggered, the number of the first outlet and the second outlet which are communicated together is reduced, and the number of seeds which are moved out through the sowing box at a time is reduced. On the contrary, the more the number of the first outlet hole and the second outlet hole which are communicated with each other in a superposition way, the more the number of the seeds moved out through the sowing box.

As shown in fig. 7 to 9, in a second embodiment of the adjusting unit, the adjusting unit includes an adjusting baffle movably or fixedly disposed outside the auxiliary baffle or the main baffle, an outer ring 81 fixed on an outer wall of the adjusting baffle, a fixing rod 83 fixed on one of the fixing plates, and an electric telescopic rod 84 fixed on an upper end of the fixing rod, wherein a telescopic rod 85 on the electric telescopic rod is fixedly connected with a protruding ring 82 rotatably mounted on an end surface of the outer ring. When the telescopic link of electric telescopic handle stretches out, can promote the removal of adjusting the baffle relative vice baffle or main baffle, when adjusting the baffle and blocking first orifice or the second and egress, the seed quantity that shifts out in the following seeding box reduces. The adjusting baffle can rotate along with the auxiliary baffle and can also be connected with the auxiliary baffle in a rotating way. When the adjusting baffle plate rotates along with the auxiliary baffle plate, the interference to the rotation of the outer ring can be avoided due to the arrangement of the convex ring.

According to the invention, the main baffle and the auxiliary baffle are arranged, so that sowing operation of seeds with different sizes can be realized, large-sized seeds such as peanuts can be moved out of the sowing box through the first outlet hole, and small-sized seeds such as corns and wheat can be sequentially moved out of the sowing box through the first outlet hole and the second outlet hole. When the seed quantity when needs adjust the seeding, can be so that partial first outlet hole staggers with the second outlet hole, and then make the first of intercommunication, second outlet hole quantity reduction, and then reduce seeding quantity.
