Description

Technical Field

[0002] Currently, after wheat is harvested, it is generally necessary to screen the wheat grains. Therefore, a screener is needed to remove impurities from the wheat grains, thereby facilitating further processing or storage of the wheat grains.

[0003] Existing Chinese patent publication number CN212791822U discloses a strong-gluten wheat grain screener, which is provided with a first screening plate and a second screening plate with screening holes of successively decreasing apertures inside the screener body, so that the strong-gluten wheat grains entering the screener body undergo secondary screening to obtain the desired strong-gluten wheat grains. In order to better screen the wheat grains, the large-aperture first screening plate adopts a vibration motor to drive the first screening plate to vibrate, so that the wheat grains are evenly spread on the first screening plate, which can quickly and efficiently screen and remove impurities from the wheat grains. The second screening plate is driven by the first reduction motor to move horizontally, thereby completing the secondary screening of the wheat grains, while reducing the blockage of the outlet, and finally efficiently completing the screening of strong-gluten wheat grains.

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] The utility model provides Figure 1-Figure 5 The strong gluten wheat grain screener shown in the figure comprises a screening box 1 with a feeding hopper 2 at the top. A vibrating screening mechanism for screening strong gluten wheat grains is provided in the screening box 1. A large particle impurity discharge pipe 10, a small particle impurity discharge pipe 16, and a wheat grain discharge pipe 20 are installed on one side of the screening box 1 in order from top to bottom.

[0028] The vibrating screening mechanism includes a coarse screening component and a fine screening component, as well as a power component that drives the coarse screening component and the fine screening component to vibrate synchronously, and the fine screening component is located below the coarse screening component; the coarse screening component includes a first screening plate 7 arranged inside the screening box 1, a first spring 9 fixed on both sides of the inner wall of the screening box 1, and a first shaft rod rotatably installed inside the screening box 1, the top end of the first spring 9 is fixedly connected to the bottom of the first screening plate 7, and the first shaft rod is equipped with a first cam 8 that can contact the bottom of the first screening plate 7, and when the first screening plate 7 is at the lowest point, the upper surface of the first screening plate 7 and the lowest end of the pipe mouth of the large particle impurity discharge pipe 10 are on the same horizontal line; the fine screening component includes a first cam 8 arranged in the screening box 1, a second screening plate 17 inside the screening box 1, second springs 18 fixed on both sides of the inner wall of the screening box 1, and a second shaft rotatably mounted inside the screening box 1, the second shaft being mounted with a second cam 19 capable of contacting the bottom of the second screening plate 17, and when the second screening plate 17 is at its lowest point, the upper surface of the second screening plate 17 is on the same horizontal line as the lowest end of the nozzle of the small particle impurity discharge pipe 16; the power member includes a second motor 23 fixed to the back side of the screening box 1, a driving pulley being mounted on the main shaft of the second motor 23, one end of each of the first and second shafts extending to the outside of the screening box 1 and being mounted with driven pulleys 24, and a belt 25 being connected between the two driven pulleys 24 and the driving pulley;

[0029] It also includes an air separation mechanism, which includes a blowing plate 12 fixed on the inner wall of the screening box 1, and a fan 13 installed on one side of the screening box 1. An air supply duct is connected between the air outlet end of the fan 13 and the blowing plate 12, and an air volume regulating valve is provided on the air supply duct. A light impurity discharge pipe 11 is provided on the side of the screening box 1 opposite to the fan 13, and a plurality of air outlet nozzles blowing air toward the light impurity discharge pipe 11 are installed on one side of the blowing plate 12.

[0030] When in use, the strong gluten wheat grains to be screened can be added into the screening box 1 through the feeding hopper 2. At this time, the first cam 8 and the second cam 19 are driven to rotate synchronously through the cooperation of the second motor 23, the driving wheel, the driven wheel 24 and the belt 25, so that the first cam 8 and the second cam 19 continuously touch the first screening plate 7 and the second screening plate 17, so that the first screening plate 7 and the second screening plate 17 vibrate synchronously under the action of the first spring 9 and the second spring 18. When the strong gluten wheat grains fall on the first screening plate 7, the first screening plate 7 will vibrate the strong gluten wheat grains. Vibration screening is performed. After screening, large particles of impurities remain on the first screening plate 7, while strong gluten wheat grains fall onto the second screening plate 17. At this time, the second screening plate 17 vibrates and screens the strong gluten wheat grains again. After screening, fine impurities remaining in the strong gluten wheat grains remain on the second screening plate 17, while the strong gluten wheat grains pass through the second screening plate 17 and fall to the bottom of the screening box 1 and are discharged from the wheat grain discharge pipe 20, thereby realizing multi-stage screening of strong gluten wheat grains, which is convenient for subsequent storage or further processing of the strong gluten wheat grains;

[0031] In the process of the strong gluten wheat grains falling after being screened by the first screening plate 7, external air can be sucked in by the fan 13 and transported into the blowing plate 12 through the air supply duct, and then blown out through the air outlet nozzle to blow away the light impurities mixed in the strong gluten wheat grains until the light impurities are blown out from the light impurity discharge pipe 11, thereby realizing the air selection of the strong gluten wheat grains, thereby improving the screening effect of the strong gluten wheat grains, realizing efficient impurity removal of the strong gluten wheat grains, and facilitating the further processing or storage of the strong gluten wheat grains.

[0032] Furthermore, in order to facilitate the rapid discharge of the wheat grains after screening through the wheat grain discharge pipe 20, as shown in FIG. Figure 1 As shown, the inner bottom of the screening box 1 forms a guide portion 21 inclined toward the pipe opening of the wheat grain discharge pipe 20.

[0033] At the same time, in this embodiment, Figure 1 、 Figure 3 and Figure 4 As shown, the screening box 1 is also provided with a scattering mechanism for dispersing the wheat grains, and the scattering mechanism includes a roller 26 rotatably installed inside the screening box 1, and a plurality of dispersion plates 3 distributed in a ring array are fixed on the outer circumference of the roller 26, and a guide trough for the wheat grains to fall quickly is provided on one side of the plurality of dispersion plates 3. A first motor 22 for driving the roller 26 to rotate is also fixed on the back side of the screening box 1, and the roller 26 is located directly below the discharge end of the feeding hopper 2.

[0034] When the wheat grains are added into the screening box 1 through the feeding hopper 2, the roller 26 can be driven to rotate by the first motor 22, so that the roller 26 drives the dispersion plate 3 to rotate, and then the wheat grains are dispersed along the guide groove and fall on the first screening plate 7 under the drive of the dispersion plate 3, so that the wheat grains fall evenly on the first screening plate 7, so as to facilitate the uniform dispersion of the wheat grains, thereby facilitating the primary screening of the wheat grains and improving the screening efficiency.

[0035] In addition, in one embodiment, Figure 1-Figure 3 as well as Figure 5 As shown, the screening box 1 is also provided with a cleaning component for cleaning the first screening plate 7 and the second screening plate 17, and the cleaning component includes a first bracket 4 and a second bracket 15 fixed to one side of the screening box 1, and a first electric push rod 5 and a second electric push rod 14 are fixed to one side of the first bracket 4 and the second bracket 15 respectively. The inner wall of the screening box 1 is provided with a cavity communicating with the first bracket 4 and the second bracket 15, and a first movable plate 6 and a second movable plate 27 are respectively provided in the two cavities, and a cleaning plate 28 is installed at the bottom of the first movable plate 6 and the second movable plate 27. The telescopic ends of the first electric push rod 5 and the second electric push rod 14 are fixedly connected to one side of the first movable plate 6 and the second movable plate 27 respectively.

[0036] After the wheat grains are screened, the first movable plate 6 and the second movable plate 27 can be driven respectively by the first electric push rod 5 and the second electric push rod 14, so that the first movable plate 6 and the second movable plate 27 drive the cleaning plates 28 at their bottom to move along the upper surfaces of the first screening plate 7 and the second screening plate 17 respectively, so as to discharge the large particles of impurities on the first screening plate 7 through the large particle impurity discharge pipe 10, and discharge the small particles of impurities on the second screening plate 17 through the small particle impurity discharge pipe 16, thereby cleaning the first screening plate 7 and the second screening plate 17, thereby avoiding blockage of the first screening plate 7 and the second screening plate 17, and facilitating multi-stage screening of wheat grains by the first screening plate 7 and the second screening plate 17.

[0037] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
