Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] For ease of description, Figure 1 The up and down direction is horizontal, Figure 1 The left and right direction is vertical,

[0025] Reference Figure 1-Figure 4 As shown, a quantitative broadcasting machine includes a broadcasting frame 1, on which symmetrically arranged material bins 2 are provided, on which a broadcasting mechanism corresponding to the material bins 2 is provided, and on which a quantitative mechanism is provided between the broadcasting mechanism and the material bins 2.

[0026] The seeding frame 1 includes parallel cross bars 11, which are arranged at intervals in front and back. The cross bars 11 are connected by a plurality of longitudinal bars 12 arranged at intervals, wherein the longitudinal bars 12 in the middle of the cross bars 11 are connected by mounting rods 13. The ends of the cross bars 11 are provided with mounting seats 14, which include a seat body, the lower end of which is fixedly connected to the cross bars 11, and the seat body is provided with a longitudinally arranged traction rod 15, on which a connecting piece can be placed, so that the traction rod 15 can be connected to a traction device, which can be a helicopter or other equipment, and the helicopter or other equipment drives the seeding machine to move forward, so as to achieve the sowing of the seed material. The lower part of the seat body is connected to the cross bars 11 by a support rod 16, which is inclined at an angle to the cross bars 11, and the upper end of the support rod 16 is fixedly connected to the inner side of the warehouse body, and the lower end of the support rod 16 and the support rod 16 of the warehouse body can increase the stability of the seat body. The silo 2 is fixedly mounted on the relatively outer side of the mounting seat 14, and the silos 2 are connected by an auxiliary rod 17, which can increase the stability of the silo 2. A feed port is provided at the upper end of the silo 2, and a silo door 21 is installed on the outer wall of the silo 2. A rotating lotus leaf 22 is provided between the silo door 21 and the silo 2, and a buckle 23 for fixing the silo door 21 is provided between the silo door 21 and the silo 2. A discharge port is provided at the lower end of the silo 2. The operator opens the silo door 21 and feeds the seed material into the silo 2, and then fixes the silo door 21 through the buckle 23.

[0027] The material broadcasting mechanism is arranged at the discharge port, and the material broadcasting mechanism includes a material broadcasting seat 31 fixedly installed between the cross bars 11, a material broadcasting motor 32 is fixedly installed on the material broadcasting seat 31, a material broadcasting wheel 33 is installed on the power output shaft of the material broadcasting motor 32, and the material broadcasting wheel 33 includes a wheel body, and a plurality of material broadcasting teeth 34 surrounding the center are evenly arranged on the upper part of the wheel body, and the material broadcasting teeth 34 are arranged vertically with the wheel body, and a material broadcasting gap is formed between adjacent material broadcasting teeth 34, and the center line of the wheel body coincides with the center line of the discharge port of the silo 2. The seed material of the silo 2 falls from the discharge port and falls onto the material broadcasting wheel 33. Since the material broadcasting wheel 33 is rotating, the rotating material broadcasting wheel 33 spreads the seed material outward, and the arrangement of the material broadcasting teeth 34 can realize the limitation of the position of the seed material spreading outward. The outer ring of the wheel body is provided with a limiting plate 35, and the limiting plate 35 is connected to the sowing seat 31 through a limiting rod. The cross-section of the limiting plate 35 is arranged in an arc shape. When the seed material is scattered through the sowing gap, the seed material will be blocked by the limiting plate 35, and therefore can only fall at the limiting plate 35, thereby realizing the sowing of the material at a limited position.

[0028] The quantitative mechanism is arranged between the wheel body and the lower end of the silo 2. The quantitative mechanism includes a power component fixedly mounted on the mounting rod 13. The power component here can be an electric push rod 41, a hydraulic cylinder or a pneumatic cylinder. In this embodiment, the power component adopts an electric push rod 41. The electric push rod 41 can be directly connected to the battery pack of the traction device. Compared with the corresponding hydraulic group or pneumatic group required by the hydraulic cylinder or the pneumatic cylinder, the connection of the electric push rod 41 is simple, and the subsequent maintenance and repair are convenient. A rotating shaft 43 is rotatably mounted on the middle position of the mounting rod 13. The rotating shaft 43 is connected to the end of the telescopic rod of the power component through a transmission rod 42. The transmission rod 42 is hinged to the end of the telescopic rod through a pin. The transmission rod 42 is fixedly connected to the lower end of the rotating shaft 43. A swing arm 44 is provided at the upper end of the rotating shaft 43. The middle position of the swing arm 44 is fixedly connected to the upper end of the rotating shaft 43. The two ends of the swing arm 44 are respectively hinged with intermediate connecting rods 45. The outer end of the intermediate connecting rod 45 is hinged An adjusting rod 46 is connected, a limiting seat is fixedly installed on the longitudinal rod 12, a limiting hole is provided on the limiting seat, the adjusting rod 46 moves through the limiting hole of the limiting seat, the adjusting rod 46 reciprocates in the axial direction of the cross bar 11, a quantitative baffle 47 is connected to the outer end of the adjusting rod 46, a laterally arranged slide 48 is provided at the lower part of the silo 2, a slide groove is provided on the relatively inner side of the slide 48, the quantitative baffle 47 is installed between the slides 48, and the quantitative baffle 47 is slidably installed in the slide groove. The operator starts the electric push rod 41, and the telescopic rod of the electric push rod 41 retracts and retracts, and the reciprocating extension and retraction of the telescopic rod drives the transmission rod 42 to swing back and forth, and the reciprocating swinging of the transmission rod 42 mobilizes the reciprocating rotation of the rotating shaft 43, and the reciprocating rotation of the rotating shaft 43 drives the swing arm 44 to swing back and forth, and the swinging of the swing arm 44 drives the movement of the connecting rod 45, and the movement of the connecting rod 45 drives the adjusting rod 46 to reciprocate in the lateral direction, and the reciprocating movement of the adjusting rod 46 drives the movement of the quantitative baffle 47. When the quantitative baffle 47 moves to the end of the cross bar 11, the quantitative baffle 47 can block the discharge port of the silo 2, and when the quantitative baffle 47 is separated from the discharge port of the silo 2, the seed material in the silo 2 will fall to the sowing wheel 33 for sowing, thereby realizing intermittent quantitative unloading of the silo 2.

[0029] When the present invention is in use, the quantitative seeding machine is first fixed on the traction device through the traction rod 15, and then the operator first opens the warehouse door 21 to send the seed material into the interior of the warehouse 2, and fixes the warehouse door 21 at the feeding port of the warehouse 2 through the buckle 23. The quantitative baffle 47 here is arranged at the discharging port of the warehouse 2, and the quantitative baffle 47 plays a blocking role. The electric push rod 41 is started, and the telescopic rod of the electric push rod 41 extends to drive the transmission rod 42 to rotate counterclockwise, and the counterclockwise rotation of the transmission rod 42 drives the rotating shaft 43 to rotate counterclockwise. The rotation of the rotating shaft 43 drives the swing arm 44 to rotate counterclockwise, and the counterclockwise rotation of the swing arm 44 drives the connecting rod 45 to move inward. The inside and outside here are close to the center of the installation rod 13 as the inside, and away from the center of the installation rod 13 as the outside. The outer end of the connecting rod 45 drives the adjusting rod 46 to move inward. Due to the setting of the limit seat and the sliding seat 48, the adjusting rod 46 can only move laterally along the axial direction of the adjusting rod 46. The inward movement drives the quantitative baffle 47 to move inward, that is, the quantitative baffle 47 is separated from the discharge port of the silo 2, and the seed material in the silo 2 falls onto the sowing wheel 33 for sowing. Due to the setting of the sowing teeth 34 and the limiting plate 35, the seed material can only be sown in a directional manner. The shortening of the telescopic rod of the electric push rod 41 drives the transmission rod 42 to rotate clockwise, and the clockwise rotation of the transmission rod 42 drives the rotating shaft 43 to rotate clockwise. The rotation of the rotating shaft 43 drives the swing arm 44 to rotate clockwise. The clockwise rotation of the swing arm 44 drives the connecting rod 45 to move outward, and the outer end of the connecting rod 45 drives the adjusting rod 46 to move outward. Due to the setting of the limit seat and the slide seat 48, the adjusting rod 46 can only move laterally along the axial direction of the adjusting rod 46. The outward movement of the adjusting rod 46 drives the quantitative baffle 47 to move outward, that is, the quantitative baffle 47 blocks the discharge port of the silo 2, thereby realizing intermittent quantitative sowing of the seed material. The quantitative mechanism has a simple structure, is convenient for subsequent maintenance, and reduces costs.
