Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of grain processing equipment, in particular to a grain screening device. Background Art
[0002] Adding baked cereals to yogurt can not only make the yogurt taste better, but also increase the nutrition of the yogurt. In order to make the baked cereals still have a crisp taste when put into yogurt, the baked cereals are usually packaged separately from the yogurt. When eating, pour the cereals into the yogurt, stir and mix before eating.
[0003] Before baking the grains, in order to prevent small grains from being over-baked and affecting the taste, the grains need to be sieved to remove small grains or impurities. Existing sieving devices mostly use a method of shaking the filter screen up and down for sieving. This method is not only noisy, but also the mesh of the filter screen is clogged with grains after a period of use. The filter screen needs to be removed for cleaning, which makes continuous production impossible, is time-consuming and labor-intensive, and affects production progress. Utility Model Content

DETAILED DESCRIPTION
[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.
[0025] like Figure 1-Figure 5 As shown, this embodiment provides a grain screening device, including a screening basket 100 and a pushing device 200 arranged on one side of the screening basket 100 .
[0026] Specifically, mounting seats are respectively provided along the width direction of the screening basket 100, and the mounting seats are respectively located at both ends of the screening basket 100. A slide groove 110 is recessed at the bottom of the mounting seat, and a track 111 is provided directly below the mounting seat. The slide groove 110 is slidably connected to the track 111. A rubber pad 120 is provided on one side of the screening basket 100 facing the pushing device 200, and a baffle assembly 130 is provided on the other side.
[0027] The pushing device 200 includes a strip seat 210, a scraping assembly 220, and a pushing assembly 230. The strip seat 210 is arranged along the length direction of the screening basket 100, and the scraping assembly 220 is perpendicular to the length direction of the strip seat 210 and is movably arranged along the length direction of the strip seat 210. The pushing assembly 230 is arranged above the scraping assembly 220 in parallel and is slidably connected to the strip seat 210.
[0028] The scraping assembly 220 includes a moving plate 221 and a scraping member 222. The moving plate 221 is slidably connected to the bottom of the strip seat 210. The scraping member 222 is arranged at one end of the moving plate 221 facing the screening basket 100, and the scraping member 222 is correspondingly located at the bottom of the screening basket 100. The scraping member 222 has a plurality of deformable teeth 225. When the teeth 225 encounter the bottom of the screening basket 100, they bend and deform, and when they encounter the sieve holes, they extend upward to move the grains in the sieve holes. The pushing assembly 230 includes a sliding plate 231, a guide rod 233, a push rod 234, and a group of supports 235. The sliding plate 231 is slidably arranged on the top surface of the strip seat 210. A guide groove 232 is provided at the midline position of the top surface of the sliding plate 231. The guide groove 232 has a wave structure and is arranged along the length direction of the sliding plate 231. The guide rod 233 is rotatably arranged in the guide groove 232. The upper end of the guide rod 233 is rotatably connected to the bottom surface of the push rod 234. The supports 235 are respectively arranged on both sides of the top surface of the sliding plate 231. The two ends of the push rod 234 are respectively penetrated in the supports 235, and the push rod 234 is slidably connected to the supports 235. The side of the push rod 234 facing the screening basket 100 corresponds to the rubber pad 120. In order to facilitate the collection of small-particle grains after screening, a collection basket 140 is arranged at the bottom of the screening basket 100.
[0029] When in use, the grains to be screened are poured into the screening basket 100, and the moving plate 221 is reciprocatedly pushed along the length direction of the strip seat 210, so that the moving plate 221 drives the scraper 222 to reciprocate along the bottom of the screening basket 100, so that the picking teeth 225 can pick the grains in the sieve holes to avoid the grains blocking the sieve holes during the screening process. When the moving plate 221 moves, the sliding plate 231 moves synchronously with the movement of the moving plate 221. The movement of the sliding plate 231 causes the guide rod 233 to swing left and right along the guide groove 222 of the corrugated structure, so that the push rod 234 pushes the screening basket 100 to move along the track 111. Because the rubber pad 120 corresponds to one end of the push rod 234 facing the screening basket 100, the noise when the push rod 234 pushes the screening basket 100 is reduced. When the push rod 234 pushes the screening basket 100 to one side of the blocking rod assembly 130, the screening basket 100 automatically moves toward the push rod 234 under the obstruction of the blocking rod assembly 130, so that the screening basket 100 reciprocates on the track 111, thereby realizing continuous screening of continuous grains.
[0030] Specifically, Figure 1-Figure 2As shown, a group of blocking rod assemblies 130 are arranged at intervals, and the blocking rod assembly 130 includes a column 131, a blocking rod 133, and a spring 134. The column 131 is correspondingly arranged at one end of the track 111 away from the bar seat 210, and a through hole 132 is arranged at the upper end of the column 131. The blocking rod 133 is inserted into the through hole 132, and the spring 134 is inserted at one end of the blocking rod 133 facing the sieve basket 100, so that the blocking rod 133 is provided with a rubber pad 120 at one end of the blocking rod 133 facing the sieve basket 100, thereby further reducing the noise generated when the sieve basket 100 contacts the blocking rod 133.
[0031] Specifically, Figure 1 As shown, a rotating assembly 240 is provided on one side of the bar seat 210 to replace manual pushing of the moving plate 221. A bar groove 223 is provided along the length direction of the moving plate 221. The rotating assembly 240 includes a rotating rod 241, a rotating plate 242, and a motor 243. One end of the rotating rod 241 is rotatably arranged in the bar groove 223, and the other end is rotatably connected to one end of the rotating plate 242. The other end of the rotating plate 242 is connected to the output end of the motor 243.
[0032] When in use, the motor 243 drives the rotating plate 242 to rotate, and the rotating plate 242 drives the rotating rod 241 to make a circular motion, so that the rotating rod 241 drives the moving plate 221 to reciprocate along the length direction of the strip seat 210 .
[0033] Specifically, Figure 1-Figure 2 , Figure 4 As shown, a slider 224 is protruding upward from the top surface of the movable plate 221, a movable groove 211 is provided in the strip seat 210, the slider 224 is slidably connected to the movable groove 211, and the upper end of the slider 224 passes through the movable groove 211 to connect to the bottom surface of the sliding plate 231, so that the sliding plate 231 is synchronously driven to move when the movable plate 221 moves.
[0034] Specifically, Figure 1-Figure 2 , Figure 5 As shown, a groove 212 is provided on the top surface of the strip seat 210, and limiting grooves 213 are provided on the inner walls on both sides of the groove 212, and limiting strips 236 are provided on both sides of the sliding plate 231. The limiting strips 236 are slidably arranged in the limiting grooves 213, thereby limiting the sliding plate 231 to reduce the thrust of the two ends of the guide groove 232 on the guide rod 233.
[0035] The above is only a preferred embodiment of the utility model, and does not mean that it is the only one or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
