Description

Technical Field

[0001] The utility model belongs to the field of vibration devices in sorghum screening machines and relates to a device used for vibrating sorghum screening machines. Background Art

[0002] Sorghum is an herbaceous plant of the Poaceae family. According to its properties and uses, sorghum can be divided into edible sorghum, sugar sorghum, broom sorghum and other categories. The grains of edible sorghum are used for food and winemaking; the stalks of sugar sorghum can be used to make syrup or be eaten raw; the ears of broom sorghum can be used to make brooms or cooking brooms; the young leaves of sorghum can be dried in the shade for silage or dried in the sun and used as feed.

[0003] Sorghum can be planted every year, so sorghum is an economic crop. After being picked, the sorghum is dried to obtain sorghum seeds. The sorghum seeds have different sizes, and sorghum seeds of different sizes have different prices. Therefore, the sorghum seeds need to be screened. The existing sorghum screening machine is connected to the vibrating structure through a flexible belt during use. Although it can complete the screening function of sorghum seeds, the flexible belt is prone to wear after a period of use, and long-term use can easily lead to the problem of damage to the flexible belt.

[0004] The vibration structure and support frame in some existing sorghum screening machines adopt a slide-type connection. Although it can also meet the screening function of sorghum seeds, the slide-type setting makes the vibration structure only able to move along the track inside the slide, making the swing amplitude of the vibration structure small, and thus it is difficult to meet the purpose of fully screening the sorghum seeds. Therefore, in order to solve the above technical problems, the technical solution of the present application is set. Utility Model Content

[0005] The purpose of this utility model is to provide a device for vibrating a sorghum screening machine, which solves the above-mentioned technical problems.

[0007] A device for vibrating a sorghum screening machine includes a horizontally arranged support frame, an inclined screening structure is provided between the support frames, the discharge end of the screening structure is located below the feed end, the outer walls on both sides of the screening structure are respectively connected to the support frame through a swing structure, the upper end of the swing structure is rotatably connected to the support frame, and the lower end of the swing structure is rotatably connected to the screening structure, and a driving structure is connected to one side of the support frame, which drives the swing structure to vibrate during operation.

[0008] The working principle of the utility model is as follows: the present application replaces the flexible belt or slide-type swinging mode in the existing sorghum screening machine by setting a swinging structure, and the two ends of the swinging structure are respectively rotatably connected to the support frame and the screening structure, so that the screening structure and the support frame are rotatably connected through the swinging structure while having a larger swinging amplitude. At the same time, the swinging amplitude is not just reciprocating motion along the sliding, so that it swings like a pendulum, so that the entire screening structure can fully swing during the screening process of sorghum seeds, thereby facilitating full screening of the sorghum seeds. At the same time, the swinging structure replaces the existing flexible belt with low strength, which will continue to wear during use and cause damage to the flexible belt due to long-term use. The problem that the screening structure in the existing sorghum screening machine has a small vibration amplitude during use, which makes it difficult to fully screen the sorghum seeds, is solved.

[0009] Furthermore: the screening structure includes an inclined screening trough, the discharge end and the feed end of the screening trough are both open and a space for screening sorghum seeds is provided between the inner walls, at least three screening plates are connected between the inner walls of the screening trough, the three screening plates are arranged at equal intervals from top to bottom along the inner wall of the screening trough, and a number of screening through holes are evenly distributed on the three screening plates, the aperture of the screening through holes on the same screening plate is the same and the aperture of the screening through holes gradually becomes smaller from top to bottom along the inner wall of the screening trough.

[0010] Furthermore, the discharge ends of the three screening plates are respectively connected to discharge troughs, the discharge ends of the three discharge troughs are all oriented in different directions, and the three discharge troughs are all arranged to be inclined downward.

[0011] Furthermore: the swing structure includes a swing bar, a first bearing, and a second bearing. The inner ring of the first bearing is fixed to the support frame through a first locking assembly, and the inner ring of the second bearing is fixed to the screening structure through a second locking assembly. The two ends of the swing bar are respectively fixed to the outer rings of the first bearing and the second bearing.

[0012] Furthermore: the first locking assembly includes a first stud and a first nut. The support frame is provided with a first through hole for the first stud to pass through. The first stud passes through the first through hole and the inner ring of the first bearing in sequence and is connected to the first nut through threads.

[0013] Furthermore: the second locking assembly includes a second stud and a second nut, and the screening structure is provided with a second through hole for the second stud to pass through. The second stud passes through the second through hole and the inner ring of the second bearing in sequence and is connected to the second nut through threads.

[0014] Furthermore: the driving structure includes a horizontally arranged telescopic cylinder, one end of the telescopic cylinder is connected to the support frame, and a telescopic shaft is connected inside the telescopic cylinder, which abuts against the front end of the screening structure when the telescopic shaft is extended.

[0015] Furthermore, the front end of the telescopic shaft is connected with a protective block, and the material of the protective block is soft rubber.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0025] The features and performance of the present invention are further described in detail below with reference to the embodiments.

[0026] Example 1

[0027] The utility model discloses a device for vibrating a sorghum screening machine, such as Figure 1 As shown, it includes a horizontally arranged support frame 1, and an inclined screening structure is provided between the support frames 1. The discharge end of the screening structure is located below the feed end. The outer walls on both sides of the screening structure are connected to the support frame 1 through a swinging structure. The upper end of the swinging structure is rotatably connected to the support frame 1, and the lower end of the swinging structure is rotatably connected to the screening structure. A driving structure is connected to one side of the support frame 1, and the driving structure drives the swinging structure to vibrate during operation.

[0028] The screening structure includes an inclined screening trough 2, the discharge end and the feed end of the screening trough 2 are both open, and a space for screening sorghum seeds is provided between the inner walls. At least three screening plates 3 are connected between the inner walls of the screening trough 2, and the three screening plates 3 are arranged at equal intervals from top to bottom along the inner wall of the screening trough 2. A number of screening through holes 4 are evenly distributed on the three screening plates 3. The apertures of the screening through holes 4 on the same screening plate 3 are the same, and the apertures of the screening through holes 4 gradually become smaller from top to bottom along the inner wall of the screening trough 2.

[0029] The discharge ends of the three screening plates 3 are respectively connected to a discharge trough 5 . The discharge ends of the three discharge troughs 5 are all oriented in different directions, and the three discharge troughs 5 are all arranged to be inclined downward.

[0030] The specific implementation method of this embodiment is: this application replaces the flexible belt or slide-type swinging method in the existing sorghum screening machine by setting a swinging structure, and the two ends of the swinging structure are respectively rotatably connected to the support frame and the screening structure, so that the screening structure and the support frame are rotatably connected through the swinging structure while having a larger swinging amplitude. At the same time, the swinging amplitude is not just a reciprocating motion along the sliding, so that it swings like a pendulum, and thus the entire screening structure is fully swung during the screening process of sorghum seeds, thereby facilitating the full screening of sorghum seeds. At the same time, the swinging structure replaces the existing flexible belt with low strength, which will continue to wear during use and cause damage to the flexible belt due to long-term use.

[0031] Preferably, the driving structure provides power for the screening structure to swing, so that the screening structure swings back and forth around the swing structure.

[0032] Preferably, the screening structure is arranged to be tilted downward so that the sorghum seeds to be screened are input through the feed end of the screening structure, and then screened inside the screening structure and discharged through the discharge end of the screening structure.

[0033] The sorghum seeds to be screened are poured into the feed end of the first screening plate, and the entire screening trough is driven to swing by the swinging structure. During the swinging process, the sorghum seeds move along the first screening plate. Preferably, the first screening plate, the second screening plate, and the third screening plate are all arranged to be inclined downward. During the swinging process, the sorghum seeds with the largest particle size are left on the first screen, the larger sorghum seeds are left on the second screening plate, and the smallest sorghum seeds are left on the third screening plate. At the same time, the debris in the sorghum seeds enters the gap between the bottom of the screening trough and the third screening plate through the screening holes on the third screening plate, and is then discharged through the bottom of the screening trough.

[0034] After the sorghum seeds are screened, they move along the corresponding screening plate to the discharge end and then enter the corresponding discharge trough. Preferably, the discharge troughs have different corresponding directions, which facilitates the separate collection of the screened sorghum seeds and avoids the problem of the screened sorghum seeds being mixed together again.

[0036] The utility model discloses a device for vibrating a sorghum screening machine, such as Figure 1 As shown, the swing structure includes a swing bar 6, a first bearing 7, and a second bearing 8. The inner ring of the first bearing 7 is fixed to the support frame 1 through a first locking assembly, and the inner ring of the second bearing 8 is fixed to the screening structure through a second locking assembly. The two ends of the swing bar 6 are respectively fixed to the outer rings of the first bearing 7 and the second bearing 8.

[0037] The first locking assembly includes a first stud 9 and a first nut. The support frame 1 is provided with a first through hole for the first stud 9 to pass through. The first stud 9 passes through the first through hole and the inner ring of the first bearing 7 in sequence and is connected to the first nut through threads.

[0038] The second locking assembly includes a second stud 10 and a second nut. The screening structure is provided with a second through hole for the second stud 10 to pass through. The second stud 10 passes through the second through hole and the inner ring of the second bearing 8 in sequence and is connected to the second nut through threads.

[0039] The specific implementation method of this embodiment is: after the first stud passes through the first through hole and the inner ring of the first bearing in sequence, the first stud is locked by the first nut. The first stud and the first nut facilitate the locking of the connection between the first bearing and the support frame, and at the same time, the upper end of the support bar is rotatably connected to the support frame. Preferably, the first stud and the first nut cooperate to facilitate disassembly and installation.

[0040] After the second stud passes through the second through hole and the inner ring of the second bearing in sequence, the second stud is locked by the second nut. The second stud and the second nut facilitate locking the connection between the second bearing and the screening slot, and at the same time, the lower end of the support bar is rotatably connected to the screening slot. Preferably, the second stud and the second nut cooperate to facilitate disassembly and installation.

[0041] The two ends of the swing bar are fixedly connected to the outer rings of the first bearing and the second bearing respectively, so that the support bar connects the first bearing and the second bearing, and at the same time facilitates the screening trough to swing around the support bar.

When the telescopic shaft 12 is extended, it abuts against the front end of the screening structure.

[0044] The front end of the telescopic shaft 12 is connected to a protective block 13 , which is made of soft rubber.

[0045] The specific implementation of this embodiment is as follows: a driving method is set up to drive the telescopic shaft to extend or retract through a telescopic cylinder, thereby driving the front end of the telescopic shaft to contact the front end of the screening slot, and finally providing power for the screening slot to swing, so that the screening slot continuously swings back and forth around the swing bar.

[0046] Preferably, a protective block is provided at the front end of the telescopic shaft to avoid direct contact and collision between the front end of the telescopic shaft and the front end of the screening slot, thereby extending the service life of the telescopic shaft and the screening slot and reducing the noise generated by the collision between the telescopic shaft and the screening slot.
