Description

Technical Field

[0001] The utility model relates to the technical field of sunflower seed screening, in particular to a sunflower seed screening machine. Background Art

[0002] Sunflower seeds are called sunflower seeds. Sunflower seeds need to be processed after harvesting. Before processing, sunflower seeds of different specifications and qualities need to be screened so that they can be used for different purposes. Mechanized harvesting operations can complete the screening of sunflower seeds during harvesting operations, while areas with complex terrain that cannot use mechanical operations need to carry out separate screening operations after the harvest.

[0021] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0022] like Figures 1 to 3As shown, a sunflower seed screening machine includes a screening frame 1, a feed port is provided on the screening frame 1, a feed device 2 is connected to the feed port, the feed device 2 is used to input the sunflower seeds into the screening frame 1, and a screening device 3 is used in the screening frame 1 to vibrate and screen the sunflower seeds, and classify and collect the screened sunflower seeds. The above technical solution is adopted to move and collect the collected sunflower seeds through the feed device 2 during operation, and the collection device uses a negative pressure conveying pipeline to transport the sunflower seeds. The feed device 2 in operation can be moved, and the feed device 2 can be controlled to move and pump according to the stacking and pumping conditions of the sunflower seeds. After the sunflower seeds are pumped into the screening device 3, the screening device 3 performs multi-stage screening on the sunflower seeds, and classifies and collects the sunflower seeds of different qualities after screening.

[0023] The feeding device 2 includes a feeding pipe 21 connected to the feeding port, one end of the feeding pipe 21 is connected to a negative pressure air pump, the negative pressure air pump is fixed in a moving frame 22, an adsorption pipe 23 is provided at the inlet of the negative pressure air pump, and a moving wheel is provided on the moving frame 22;

[0024] The feeding pipe 21 is made of flexible and telescopic material.

[0025] By adopting the above technical solution, the mobile frame 22 is controlled to move according to the stacking situation of the sunflowers during operation. The flexible and telescopic material conveying pipe 21 can cooperate with the negative pressure air pump in the mobile frame 22 during operation, and can smoothly move the position of the sunflower stacking to adapt to the situation.

[0026] The screening device 3 includes a vibration frame 31 slidably arranged in the screening frame 1, a support spring rod 32 is connected between the vibration frame 31 and the screening frame 1, a vibration motor is arranged on the vibration frame 31, the vibration frame 31 is an inclined structure, and the vibration frame 31 is evenly provided with drop openings, the vibration frame 31 is evenly spaced with isolation mechanisms 33, and the screening frame 1 is provided with a control mechanism 34 for controlling the operation of the isolation mechanism 33;

[0027] By adopting the above technical solution, the sunflower seeds transported by the feeding device 2 enter the vibration frame 31 during operation. The vibration frame 21 is tilted. The sunflower seeds entering the vibration frame 31 move downward in an inclined direction under the action of gravity. During this process, the vibration motor is synchronously started. The vibration motor cooperates with the support spring rod 32 during operation to drive the vibration frame 31 to vibrate up and down reciprocatingly. By adopting this method, the sunflower seeds are screened. In order to improve the screening effect of the sunflower seeds, the sunflower seeds are screened in batches multiple times through the cooperation between the control mechanism 34 and the isolation mechanism 33, so that the defective products that do not meet the specifications and impurities such as dust in the sunflower seeds are discharged downward from the drop port.

[0028] The isolation mechanism 33 includes a lifting groove provided on the vibration frame 31, a lifting plate 331 is slidably provided in the lifting groove, a horizontal plate 332 is provided on the lifting plate 331, a return spring rod 333 is provided between the horizontal plate 332 and the vibration frame 31, and a control sleeve 334 is provided on the horizontal plate 332;

[0029] The control mechanism 34 includes a control cylinder 335 disposed on the vibration frame 31, and a control rod 336 is disposed on the control cylinder 335. The control rod 336 is provided with a control part that cooperates with the control sleeve 334. The control part cooperates with the control sleeve 334 to control the lifting plate 331 to move in the lifting groove, so as to control the movement of the sunflower seeds, thereby achieving the purpose of multiple screening of the sunflower seeds;

[0030] Preferably, a No. 1 opening is opened at the rear side of the screening frame 1, a No. 2 opening is opened at the left end of the screening frame 1, and a No. 3 opening is opened at the right end of the screening frame 1.

The lower end of the vibration frame 31 is provided with a left-downward inclined screening plate cooperating with the No. 2 port and a right-downward inclined screening plate cooperating with the No. 3 port from top to bottom. The screening holes opened on the left-downward inclined screening plate are used to screen out dust and impurities in the defective sunflower seeds.

[0032] By adopting the above technical solution, when it is necessary to control the isolation mechanism 34 to work during operation, the control cylinder 335 is started to drive the control rod 336 to move. During the movement, the control rod drives the control part to move in the direction of the control sleeve 334. The positions of the multiple control parts and the control sleeves are staggered. That is, when the first control part cooperates with the control sleeve 334 to move the lifting plate 331 so that the sunflower seeds can move, the second control part separates from the control sleeve 334, and the lifting plate 331 at this position is in a closed state, so that the sunflower seeds cannot move in the direction of the No. 1 mouth. The movement state of the sunflower seeds is controlled by the movement of the control rod 336, so as to achieve the purpose of multiple screening of the sunflower seeds.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
