Description

Technical Field

[0001] The utility model relates to the field of screening machines, in particular to a seed grading and screening machine. Background Art

[0002] Screening machine is a kind of machine used to screen, classify and separate materials in the production and processing process. Currently, the common screening machines on the market mainly include vibration screening machines, centrifugal screening machines, pressure screening machines, cyclone separators and other types. Although the working principles of these screening machines are different, most of them use physical screening to achieve the effect of separating materials.

[0003] In the process of using traditional screening machines on the market, most of them directly pour the materials into the feed pipe, and then the materials will fall onto the screen. The screen will screen the materials of different sizes during the vibration process to complete the screening operation. However, some screening machines on the market have a sealed structure during use, and some materials will be mixed with a large amount of impurities inside, and the screening device with a sealed structure cannot clean them, such as a seed grading screening machine with publication number CN212821059U. Secondly, most of the screening devices on the market directly let the materials fall into the screening slot, and cannot process the impurities in the materials, such as the fallen shell, the skin fallen off the surface of the material, and some small magazines, which leads to a large amount of impurities blocking the screening holes in subsequent operations, thereby reducing the screening efficiency. Utility Model Content

[0004] The main purpose of the utility model is to provide a seed grading and screening machine, which can effectively solve the problems in the background technology.

[0011] Furthermore, a material receiving box in an oblique state is fixedly mounted on the upper end surface of the main body mounting frame, and the material receiving box is located below the filter tank.

[0012] Furthermore, the upper end surfaces of the main body mounting frame are located on both sides of the filter tank and protrude upwards, and a support rod is fixedly installed on the protruding upper end surface, and a feed pipe is fixedly installed on the inner side of the support rod.

[0024] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] As shown in the figure, this embodiment provides a seed grading and screening machine, including a main body mounting frame 1, a support leg is fixedly installed at the corner of the lower end surface of the main body mounting frame 1, and a material box 9 is placed on the lower end surface of the main body mounting frame 1. Among them, one side of the main body mounting frame 1 is located in the middle of the material box 9, so that half of the material box 9 is located outside the main body mounting frame 1, so as to receive the screened materials, such as Figure 1 shown.

[0026] The edges of both sides of the upper end surface of the main body mounting frame 1 protrude upwards, and a vertical plate is fixedly installed on the upper end surface of the protruding structure, and the vertical plate is symmetrical. Secondly, a U-shaped limit rod 72 is installed on the vertical plate, and the opening of the U-shaped limit rod 72 passes through the corresponding vertical plate. A horizontal spring 71 is fixedly installed on the inner side of the vertical plate. The U-shaped limit rod 72 is located inside the spring 71. The other end of the spring 71 is fixedly installed with a vertical plate of the same structure. The lower end of the vertical plate is fixedly installed with a filter tank 7, as shown in FIG. Figure 1 shown.

[0027] During use, the U-shaped limit rods 72 on both sides can keep the filter tank 7 in a horizontal state, and the spring 71 can prevent the two sides of the filter tank 7 from colliding with the inner side of the protruding structure of the main mounting frame 1, thereby ensuring the safety of the filter tank 7 and the stability of the structure.

[0028] The interior of the filter tank 7 is concave downward, and a plurality of sieve holes are opened on the inner bottom surface to the other end to screen the material. A receiving box 8 in an inclined state is fixedly installed on the upper end surface of the main mounting frame 1. The receiving box 8 is located below the filter tank 7, and one end of the receiving box 8 is higher than the other end, so that the material falling into the receiving box 8 can roll down and fall into the interior of the material box 9. Figure 1As shown. Among them, one end of the material receiving box 8 close to the material box 9 is lower than the other end (wherein, the upper end surface of the material receiving box 8 is concave downward, and the end close to the material box 9 is penetrated, so that the interior of the material receiving box 8 is in a U-shaped state, so that the material can slide into the material box 9 smoothly). Figure 1 shown.

[0029] The upper end surface of the main mounting frame 1 is fixedly mounted with a reciprocating motor 6, which is located at the higher end of the receiving box 8. Figure 2 A rotating rod 61 is fixedly mounted on the output shaft of the reciprocating motor 6, and a through slot is formed on the rotating rod 61 from one side to the other side, and a connecting rod is fixedly mounted at the center of one side surface of the filter tank 7 close to the reciprocating motor 6, and the connecting rod extends to the inside of the through slot formed on the rotating rod 61, as shown in FIG. Figure 2 shown.

[0030] When the output shaft of the reciprocating motor 6 rotates synchronously with the rotating rod 61, the connecting rod can move left and right under the action of the rotating rod 61. The connecting rod can slide inside the rotating rod 61 during the movement. Therefore, there will be no situation where the connecting rod and the rotating rod 61 affect each other, resulting in the connecting rod being unable to drive the filter tank 7 to move left and right.

[0031] When the filter tank 7 moves left and right, the U-shaped limiting rods 72 on both sides can be driven to move synchronously, and the springs 71 on both sides can be compressed and stretched.

[0032] like Figure 3 As shown, vertical support rods are fixedly installed on the top surface of the protruding structure on the main mounting frame 1 near the two corners of the reciprocating motor 6, and a feed pipe 2 is fixedly installed between the inner sides of the two support rods.

[0033] The interior of the feed pipe 2 is in a hollow state, and a plurality of right-angled triangle-shaped slopes are staggeredly installed on the inner side wall of the feed pipe 2. After the material enters the interior of the feed pipe 2 from the top entrance of the feed pipe 2, the material will pass through a plurality of inclined surfaces, thereby slowing down the falling speed of the material. Figure 4 shown.

[0034] An air inlet 25 is provided on one end surface of the feed pipe 2 near the bottom opening. The air inlet 25 extends from the outer side surface of the feed pipe 2 to the inside of the feed pipe 2. A cavity box 3 is fixedly installed on the outer edge of the air inlet 25. The interior of the cavity box 3 is hollow, and one end surface that is in contact with the air inlet 25 penetrates through it. Figure 4As shown. A plurality of fans 4 are fixedly installed inside the cavity box 3 to provide wind power. When the material falls, the outer shell and lighter debris in the material can be blown away, so as to ensure the subsequent screening operation and prevent excessive impurities from affecting the filter holes of the filter tank 7. A grille is fixedly installed inside the air inlet 25 near the inner edge of the feed pipe 2. The grille can prevent impurities from floating into the cavity box 3 and causing damage to the fan 4.

[0035] The other end face of the feed pipe 2 is provided with a material outlet 23, wherein the material outlet 23 and the air inlet 25 are in a horizontal state, and impurities in the fallen materials will float out from the material outlet 23 under the action of wind when the fan 4 is in operation. Among them, the inclined surface near the bottom outlet inside the feed pipe 2 has a right angle side located above the air inlet 25, so the material is close to the material outlet 23 when sliding down from the bottom inclined surface.

[0036] U-shaped chutes 24 are fixedly installed at both ends of the miscellaneous material outlet 23 on one end surface of the feed pipe 2, and a miscellaneous material bag 5 is slidably installed between the two U-shaped chutes 24, and the miscellaneous material bag 5 is connected to the miscellaneous material outlet 23, so that impurities passing through the miscellaneous material outlet 23 will enter the interior of the miscellaneous material bag 5, thereby preventing impurities from contaminating the site and equipment. In addition, the structure of the miscellaneous material bag 5 slidably installed between the two U-shaped chutes 24 is an aluminum structure, and the structure not located between the U-shaped chutes 24 is a cloth material, which is used to prevent the miscellaneous material bag 5 from having an arc structure at the position where the U-shaped chutes 24 are installed, which causes the miscellaneous material bag 5 to affect the rotation of the rotating rod 61 (wherein the aluminum structure at the front end of the miscellaneous material bag 5 is located at the upper end of the reciprocating motor 6).

[0037] The working principle is as follows: during use, one aluminum end of the material bag 5 is slidably installed inside the U-shaped slide groove 24 , so that the material bag 5 can be closely attached to the outer outlet of the material outlet 23 .

[0038] Then, during the use at home, the personnel pour the material into the inside of the feeding pipe 2, so that the material can pass through the obstruction of multiple layers of inclined surfaces inside the feeding pipe 2, thereby slowing down the falling speed of the material.

[0039] Then, when the material is falling, the fan 4 is started, and the impurities in the material can pass through the miscellaneous material outlet 23 and enter the interior of the miscellaneous material bag 5 under the action of wind force, so that the material will not be affected and fall into the interior of the filter tank 7, thereby performing the first screening.

[0040] Finally, the material after impurity screening will fall into the inside of the filter tank 7, and the reciprocating motor 6 will be started. The output shaft of the reciprocating motor 6 will drive the rotating rod 61 to perform fan-shaped movement, and the rotating rod 61 will drive the filter tank 7 to move left and right during the movement of the rotating rod 61. During the movement of the filter tank 7, the smaller materials in the material can fall into the inside of the receiving box 8, and then the materials will slide into the inside of the material box 9. The larger impurities will be left in the filter tank 7 and finally cleaned away manually, thereby completing the screening operation.

[0041] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which shall fall within the scope of the utility model to be protected. The scope of protection of the utility model shall be determined by the attached claims and their equivalents.
