Description

Technical Field

[0001] This utility model relates to the field of crop seed impurity separation technology, and in particular to a crop seed impurity separation device. Background Technology

[0002] Agricultural sowing requires a large number of high-quality seeds, but many seeds are not plump and contain some impurities. These imperfections can damage the sowing machine during the sowing process and reduce yield. Therefore, a screening device is needed to screen the seeds.

[0003] Traditional seed impurity separation devices for crops have some drawbacks. In actual use, when screening seeds, the screening chamber is moved repeatedly to separate impurities smaller than the seeds. Since only impurities inside the seeds can be separated, some seeds have dust or shells on their surface. Therefore, when separating impurities inside the seeds, the dust or shells on the seeds cannot be removed, which reduces the seed impurity separation effect. Utility Model Content

[0004] The main objective of this invention is to provide a seed impurity separation device for crops, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A seed impurity separation device for crops includes a frame. A seed screening mechanism is provided at the upper end of the frame. The seed screening mechanism includes a pulley fixedly connected to the upper end of the frame. A screening chamber is slidably connected to the upper end of the pulley. A sliding plate is fixedly connected to the front end of the screening chamber. A support member is slidably connected to the outer side of the sliding plate. A support rod is fixedly connected to the upper end of the support member. An adjustment chamber is fixedly connected to the rear end of the support rod. A placement groove is provided at the bottom inner side of the adjustment chamber. A positioning hole is provided at the bottom inner side of the adjustment chamber near the rear side of the placement groove. A brush is placed inside the placement groove. A limiting plate is fixedly connected to the rear end of the brush. A pin is movably connected to the inner side of the positioning hole.

[0007] Preferably, the front end of the support member is fixedly connected to a fixing rod, the number of pulleys is four sets, and the inner bottom of the screening chamber is provided with screening holes.

[0008] Preferably, the rear end of the fixing rod is fixedly connected to the front end of the frame near the lower side of the support member, the control chamber is located above the screening chamber, and the lower end of the brush is in contact with the inner bottom of the screening chamber.

[0009] Preferably, the upper end of the pin is fixedly connected to the lower end of the limiting plate, and the limiting plate is in contact with the inner bottom of the regulating chamber.

[0010] Preferably, a support platform is fixedly connected to the inner side of the frame, a motor is fixedly connected to the upper end of the support platform, a driver is installed at the front end of the motor, a connecting rod is installed at the rear end of the driver near the upper side of the motor, and a feeding rack is fixedly connected to the inner side of the frame near the support platform.

[0011] Preferably, the feeding rack is located below the screening chamber, the lower end of the driver is installed on the upper end of the frame near the four sets of pulleys, and one end of the connecting rod is installed at one end of the screening chamber.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. By repeatedly sliding the screening chamber on the pulley, the screening chamber moves the seeds and brings them into contact with the brush. This allows the seeds to be cleaned by the brush during the separation of impurities, thus facilitating the removal of dust or shells from the seed surface and improving the separation of impurities.

[0014] 2. When the screening chamber moves, it brings the seeds into contact with the brush, allowing the brush to flatten the seed pile and prevent the seeds from forming clumps in the screening chamber, which would affect the separation of impurities. Attached Figure Description

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figure 1-4 As shown, a seed impurity separation device for crops includes a frame 1. A seed screening mechanism 7 is provided at the upper end of the frame 1. The seed screening mechanism 7 includes a pulley 71 fixedly connected to the upper end of the frame 1. A screening chamber 72 is slidably connected to the upper end of the pulley 71. A sliding plate 73 is fixedly connected to the front end of the screening chamber 72. A support member 74 is slidably connected to the outer side of the sliding plate 73. A support rod 76 is fixedly connected to the upper end of the support member 74. An adjustment chamber 77 is fixedly connected to the rear end of the support rod 76. A placement groove 78 is provided at the bottom inner side of the adjustment chamber 77. A positioning hole 79 is provided at the bottom inner side of the adjustment chamber 77 near the rear side of the placement groove 78. A brush 710 is placed inside the placement groove 78. A limiting plate 711 is fixedly connected to the rear end of the brush 710. A pin 712 is movably connected to the inner side of the positioning hole 79.

[0022] In this embodiment, a fixing rod 75 is fixedly connected to the front end of the support member 74, and there are four sets of pulleys 71. A screening hole is opened at the bottom inner side of the screening chamber 72. The rear end of the fixing rod 75 is fixedly connected to the front end of the frame 1 near the lower side of the support member 74. The control chamber 77 is located above the screening chamber 72. The lower end of the brush 710 is in contact with the bottom inner side of the screening chamber 72. The upper end of the pin 712 is fixedly connected to the lower end of the limiting plate 711. The limiting plate 711 is in contact with the bottom inner side of the control chamber 77.

[0023] Specifically, repeatedly moving the screening chamber 72 causes it to slide on the pulley 71, and the screening chamber 72 drives the sliding plate 73 to slide repeatedly within the support member 74. This allows the seeds in the screening chamber 72 to be screened, and impurities in the seeds to fall through the screening holes. Simultaneously, as the screening chamber 72 moves, it brings the seeds into contact with the brush 710, allowing the brush 710 to sweep away dust or shells from the seed surface. The brush 710 also flattens the seed pile, preventing the seeds from forming clumps within the screening chamber 72, which would hinder impurity separation. By repeatedly moving the screening chamber 72 on the pulley 71, the seeds move, and the screening chamber 72 brings the seeds into contact with the brush 710. This facilitates the cleaning of the seed surface by the brush 710 during impurity separation, thus improving the impurity separation effect.

[0024] In this embodiment, a support platform 2 is fixedly connected to the inner side of the frame 1, a motor 3 is fixedly connected to the upper end of the support platform 2, a driver 4 is installed at the front end of the motor 3, a connecting rod 5 is installed at the rear end of the driver 4 near the upper side of the motor 3, a feeding rack 6 is fixedly connected to the inner side of the frame 1 near the support platform 2, the feeding rack 6 is located below the screening chamber 72, the lower end of the driver 4 is installed at the upper end of the frame 1 near the four sets of pulleys 71, and one end of the connecting rod 5 is installed at one end of the screening chamber 72.

[0025] Specifically, the motor 3 is started, which drives the driver 4 to rotate, and the driver 4 pulls the screening chamber 72 repeatedly through the linkage 5, thereby screening the seeds in the screening chamber 72 and causing impurities in the seeds to fall through the screening holes.

[0026] Working principle:

[0027] In use, first remove the brush 710, which then passes through the limiting plate 711 to drive the pin 712, disengaging the pin 712 from the inner side of the positioning hole 79. Next, pour the seeds into the placement trough 78, causing them to fall into the sieving chamber 72 and spread out. Then, place the brush 710 back into the placement trough 78, and pass through the limiting plate 711 to insert the pin 712 into the positioning hole 79. Then, start the motor 3, causing the driver 4 to rotate. The driver 4, through the linkage 5, pulls the sieving chamber 72 repeatedly, causing it to slide on the pulley 71. The sieving chamber 72 also causes the sliding plate 73 to slide repeatedly within the support member 74, thereby allowing the seeds in the sieving chamber 72 to... The seeds are sieved, and impurities inside the seeds fall through the sieve holes. At the same time, when the sieve chamber 72 moves, it causes the seeds to come into contact with the brush 710, so that the brush 710 can sweep away the dust or shells on the surface of the seeds. The brush 710 can also flatten the seed pile, preventing the seeds from forming clumps in the sieve chamber 72, which would affect the separation of impurities. By pulling the sieve chamber 72 to slide repeatedly on the pulley 71, the sieve chamber 72 moves the seeds, and the sieve chamber 72 causes the seeds to come into contact with the brush 710. This achieves the purpose of cleaning the seed surface with the brush 710 when separating impurities, thus making it easier for the brush 710 to sweep away the dust or shells on the seed surface and improve the separation effect of impurities from the seeds.
