Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of grain grading equipment, and more specifically to an automatic grain grading device. Background Art
[0002] Grain refers to the general term for various plant seeds used in cooking food, also known as "cereals". It is rich in nutrients, mainly protein, vitamins, dietary fiber, fat, etc. It is a staple food in the human diet and is usually harvested in autumn. In the process of grain processing, grading and screening becomes an important processing step because the grain contains leaves, straw, small stones, full grains and inferior grains.
[0003] Commonly used grading and screening devices mostly use fixed installation of the screening net, which is not convenient to replace the filter nets with different apertures according to different grain crops, and the screening accuracy is not high, and leaves, straws, small stones, full grains and inferior grains cannot be effectively graded and screened out, which brings certain inconvenience to the later grain processing. In addition, the screened grains and impurities are easy to clog the filter net, affecting the screening efficiency. The existing patent is a grain grading and screening device, and the patent authorization number is CN219597293 U. It is not only convenient to replace the filter nets with different apertures according to different grain crops, and has strong applicability, but also can effectively grade and screen leaves, straws, small stones, full grains and inferior grains, and can avoid clogging of the filter net, further improving the screening efficiency.
[0004] However, in the patent authorization number CN 219597293 U, starting the electric telescopic rod to drive the push plate forward can not only prevent grain or impurities from clogging the filter screen, but also push the graded grain, impurities, etc. to the discharge port. Since the electric telescopic rod is used to push the grain to the discharge port, the energy consumption is increased and there is room for improvement. Therefore, we propose an automatic grain grading device to solve the above-mentioned problems. Utility Model Content

[0033] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.
[0034] Example:
[0035] See also Figure 1-6 , an automatic grain grading device, comprising a chassis 1 and a base 12 installed below the chassis 1;
[0036] The inner wall of the chassis 1 is symmetrically fixedly connected with a supporting boss 2 arranged at an angle, and a plurality of supporting bosses 2 are arranged equidistantly in the longitudinal direction;
[0037] A first sieve frame 3, a second sieve frame 5 and a material tray 7 are fixedly connected to the plurality of supporting bosses 2;
[0038] A first sieve 4 is installed at the bottom of the first sieve frame 3, and a second sieve 6 is installed at the bottom of the second sieve frame 5;
[0039] A vibration motor 8 is installed on the top of the chassis 1, and an eccentric vibrator is installed at the power output end of the vibration motor 8;
[0040] Support legs 10 are symmetrically welded at the roots of the outer walls on both sides of the chassis 1, and guide pillars 11 are welded at the roots of the support legs 10. A vertical plate 13 corresponding to the support legs 10 is fixedly connected to the upper surface of the base 12. A guide hole 14 is provided on the surface of the vertical plate 13 to match the guide pillar 11. A support plate 15 is welded on the surface of the vertical plate 13 close to the support legs 10, and a spring 16 is installed between the support plate 15 and the support legs 10.
[0041] It should be noted that when the automatic grain grading device is in use, the grain to be graded is poured into the first sieve frame 3, and the vibration motor 8 is turned on at the same time. The elastic force of the spring 16 is used to make the guide column 11 cooperate with the guide hole 14 to slide up and down, so as to vibrate the chassis 1 as a whole, and the first sieve frame 3, the second sieve frame 5 and the material tray 7 are set at an angle by using the supporting boss 2. The grain is screened in turn by using the first sieve 4 and the second sieve 6, and then the grain is discharged through the ports of the first sieve frame 3, the second sieve frame 5 and the material tray 7, thereby realizing the step-by-step screening of the grain. Only one vibration motor 8 is needed to work, which effectively reduces energy consumption.
[0042] like Figure 6 As shown, a cushioning rubber pad 17 is compositely bonded to the upper surface of the support plate 15, and the cushioning rubber pad 17 corresponds to the bottom end of the supporting foot 10;
[0043] It should be noted that during vibration, the chassis 1 can effectively isolate vibration and absorb impact force by contacting the buffer rubber pad 17 through the bottom end of the support foot 10, thereby effectively avoiding the support foot 10 from directly hitting the support plate 15, thereby effectively reducing noise.
[0044] like Figure 3As shown, the angle between the support boss 2 and the horizontal plane at the bottom of the chassis 1 is 5°, and the two longitudinally adjacent support bosses 2 are arranged in reverse, and both ends of the first sieve frame 3, the second sieve frame 5 and the material tray 7 extend to the outside of the chassis 1;
[0045] It should be noted that it is beneficial for the grain to be discharged through the ports of the first sieve frame 3, the second sieve frame 5 and the material tray 7 under the action of vibration.
[0046] like Figure 5 , Figure 6 As shown, the first screen 4 is half-width, the second screen 6 is full-width, and the mesh size of the second screen 6 is smaller than that of the first screen 4;
[0047] It should be noted that, by setting the first sieve 4 in half width, the grain sieved from the first sieve 4 can be prevented from falling on the port of the second sieve frame 5, which can improve the screening and grading effect.
[0048] like Figure 1 As shown, the top edge of the chassis 1 is fixedly connected to a hopper 9 via a bracket, and the bottom end of the hopper 9 corresponds to the end of the first sieve frame 3;
[0049] It should be noted that the hopper 9 is used to conveniently add the grain to the first sieve frame 3 .
[0050] like Figure 1 , Figure 4 As shown, one end of the spring 16 is connected to the support plate 15, and the other end of the spring 16 is connected to the bottom end of the support foot 10;
[0051] It should be noted that the elastic force of the spring 16 is used to make the guide post 11 slide up and down in coordination with the guide hole 14, thereby causing the chassis 1 to vibrate as a whole.
[0052] When in use: pour the grain to be graded into the first sieve frame 3, turn on the vibration motor 8 at the same time, use the elastic force of the spring 16 to make the guide column 11 slide up and down in cooperation with the guide hole 14, so as to vibrate the chassis 1 as a whole, use the supporting boss 2 to make the first sieve frame 3, the second sieve frame 5 and the material tray 7 all set at an angle, use the first sieve 4 and the second sieve 6 to screen the grain in turn, and then the grain is discharged through the ports of the first sieve frame 3, the second sieve frame 5 and the material tray 7, thereby realizing the step-by-step screening of the grain.
[0053] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
