Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically a primary selection, threshing, and separation device for tiger nuts. Background Technology

[0002] Tiger nuts are annual plants belonging to the Cyperaceae family. They are a high-quality, high-yield, and promising economic crop that integrates grain, oil, livestock, and forage functions, introduced to my country from Africa a few years ago by agricultural research departments. Because tiger nuts grow as grass above ground and bear fruit underground, weeding is necessary, and after weeding, the remaining soil, leaves, and fruits need to be removed.

[0003] Chinese utility model patent CN222888274U discloses a primary threshing and separating device for tiger nuts, which improves the separation effect of tiger nuts by modifying the threshing and separating equipment. One end of the threshing chamber is the outlet for separated nut leaves, and the other end is the inlet for unseparated nut leaves. A threshing and separating main shaft and a screen cylinder shaft are mounted on the side walls of the threshing chamber via bearings. The main shaft and screen cylinder shaft are respectively equipped with a main shaft gear and a screen cylinder shaft gear. A threshing mechanism is installed on the threshing and separating main shaft inside the threshing chamber, and a screen cylinder is installed on the screen cylinder shaft inside the threshing chamber. The advantages of this utility model are its simple structural design and low operating resistance. The combination of bow teeth and nail teeth effectively improves the threshing rate and harvesting efficiency of corn kernels, reduces kernel damage, and removes soil and some weeds through the screen cylinder, reducing screen clogging.

[0004] Existing tiger nut primary selection and threshing separation devices cannot completely separate tiger nuts due to the high viscosity and tight adhesion of the soil on their surface. Residual soil not only increases the weight of the material but also contaminates the equipment and affects the quality of the oil during subsequent processing. Furthermore, the strong adhesion between undried tiger nuts and impurities makes it difficult to dry the tiger nuts.

[0005] Therefore, this utility model provides a primary selection, threshing, and separation device for tiger nuts to solve the above-mentioned problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a device for the initial selection, threshing, and separation of tiger nuts, such as... Figures 1 to 5As shown, the device includes a screening shell 1, a loading and unloading mechanism 2 fixedly connected to the outer surface of the screening shell 1, and a primary selection mechanism 3 rotatably connected to the inner wall of the screening shell 1. The loading and unloading mechanism 2 includes a fixed frame 207 and a support rod 202 fixedly connected to the outer surface of the screening shell 1. A limit groove 210 is formed on the outer surface of the fixed frame 207, and a sealing plate 204 is slidably connected to the outer surface of the limit groove 210. A first electric telescopic rod 201 is fixedly connected to the outer surface of the support rod 202, and a sliding plate 208 is fixedly connected to the output end of the first electric telescopic rod 201. The primary selection mechanism 3 includes a rotating shaft 304 rotatably connected to the inner wall of the screening shell 1. Multiple sets of support frames 305 are fixedly connected to the outer surface of the rotating shaft 304, and a rotating frame 302 is fixedly connected to the outer surface of the support frames 305. Multiple sets of resistance heating wires 306 are embedded inside the screening shell 1, and a temperature sensor 307 is fixedly connected to the inner wall of the screening shell 1.

[0027] The primary selection mechanism 3 also includes a collection frame 301 that is slidably connected to the inner wall of the screening housing 1. A control panel 4 is fixedly connected to the outer surface of the screening housing 1. The outer surface of the control panel 4 is electrically connected to the outer surface of the temperature sensor 307 through a wire. The temperature sensor 307 facilitates the detection of the temperature inside the screening housing 1, and the collection frame 301 facilitates the removal of debris and impurities from the screening housing 1.

[0028] A geared motor 303 is fixedly connected to the outer surface of the screening shell 1. The output shaft of the geared motor 303 is fixedly connected to the outer surface of the rotating shaft 304, and the other end of the rotating shaft 304 is rotatably connected to the outer surface of the support rod 202. By starting the geared motor 303, the output shaft of the geared motor 303 drives the rotating shaft 304 to rotate. The rotation of the rotating shaft 304 drives the support frame 305 and the rotating frame 302 to rotate, thereby causing the tiger nuts to rotate repeatedly on the inner wall of the rotating frame 302. This facilitates the screening of impurities and debris from the tiger nuts into the collection frame 301. At the same time, the surface of the tiger nuts is dried by heating with a resistance heating wire 306, which facilitates the separation of impurities and soil from the tiger nuts.

[0029] A feeding plate 205 is fixedly connected to the inner wall of the fixed frame 207. A vibration motor 206 is fixedly connected to the center of the lower surface of the feeding plate 205. When the vibration motor 206 is started, the vibration motor 206 vibrates and drives the feeding plate 205 to vibrate, thereby increasing the flow of tiger nuts. Through the coordinated work of the vibration motor, the reduction motor and the resistance heating wire, the tiger nuts are separated efficiently. The vibration motor promotes the rapid flow of tiger nuts and speeds up the feeding speed; the reduction motor drives the rotating frame to rotate, causing the tiger nuts to tumble and collide continuously, accelerating the removal of impurities; the resistance heating wire dries the surface of the tiger nuts and reduces the adhesion of impurities. The combination of the three greatly improves the separation efficiency.

[0030] A second electric telescopic rod 203 is fixedly connected to the outer surface of the fixed frame 207. The output end of the second electric telescopic rod 203 is fixedly connected to the lower surface of the sealing plate 204. By activating the second electric telescopic rod 203, the output end of the second electric telescopic rod 203 drives the sealing plate 204 to slide on the outer surface of the limiting groove 210, thereby facilitating the sealing of the feed inlet of the screening shell 1.

[0031] A limiting rod 209 is fixedly connected to the outer surface of the sliding plate 208. The outer surface of the limiting rod 209 is slidably connected to the outer surface of the support rod 202. The limiting rod 209 facilitates the limiting of the sliding plate 208, allowing it to slide along the limiting rod 209. This facilitates the separation of the sliding plate 208 from the inner wall of the rotating frame 302, allowing the pre-selected tiger nuts to be discharged through the gap between the sliding plate 208 and the rotating frame 302. When the resistance heating wire is working, the temperature sensor provides real-time temperature data feedback, and the control panel adjusts the heating power in a timely manner according to the set parameters to prevent excessive temperature from damaging the quality of the tiger nuts. The sealed space formed by the sealing plate reduces heat loss and creates conditions for stable temperature control.

[0032] When the tiger nuts primary selection and threshing separation device is working, the tiger nuts enter the screening shell 1 through the feeding plate 205. The vibration motor 206 is started, and the feeding plate 205 vibrates accordingly, promoting the flow of tiger nuts and improving their efficiency in entering the screening shell 1. The second electric telescopic rod 203 drives the sealing plate 204 to slide, opening the feed inlet of the screening shell 1. After the tiger nuts smoothly enter, the sealing plate 204 closes the feed inlet, forming a relatively enclosed space. This prevents dust and impurities from entering the screening shell 1 during subsequent operations, interfering with the separation process. It also reduces heat loss, creating a favorable environment for the resistance heating wire 306 to function. Next, the geared motor 303 starts, and its output shaft drives the rotating shaft 304 to rotate, causing the support frame 305 fixed on the rotating shaft 304 to rotate together with the rotating frame 302. The tiger nuts continuously roll and collide inside the rotating frame 302. During this process, the debris and impurities they carry gradually fall off and fall into the collection frame 301 below. At the same time, the resistance heating wire 306 starts working, heating the inside of the screening shell 1, drying the surface of the tiger nuts. The soil and other impurities that were originally attached to the surface of the tiger nuts lose their stickiness due to drying and are easier to separate from the tiger nuts, significantly improving the separation effect. The temperature sensor 307 monitors the temperature inside the screening shell 1 in real time and feeds the data back to the control panel 4 to ensure that the heating process is within a suitable temperature range and to avoid excessive temperature damaging the quality of the tiger nuts. Once the initial selection is complete, the first electric telescopic rod 201 pushes the sliding plate 208 to move. Through the limiting action of the limiting rod 209, the sliding plate 208 separates from the inner wall of the rotating frame 302, forming a gap. The tiger nuts that have undergone preliminary screening, threshing, and surface drying are discharged from this gap, completing the entire initial selection, threshing, and separation process.
