DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] See also Figure 1-6 , an embodiment provided by the utility model:
[0026] A rice screening device for paddy processing, comprising:
[0027] The main body includes a body shell 1, a feed port 11 is fixedly connected to one side of the body shell 1, a connecting spring 13 is fixedly connected to the other side of the body shell 1, a discharge pipe 12 is fixedly connected to the side of the body shell 1, a base 14 is fixedly connected to the surface of the connecting spring 13, and a vibration motor 15 and a screen assembly 16 are installed inside the body shell 1. When screening rice, the vibration motor 15 should be started first and the body shell 1 should be vibrated by the connection of the connecting spring 13. At this time, the rice is poured into the feed port 11 and the rice is screened by the screen assembly 16 under the vibration of the vibration motor 15. After screening, the rice is discharged from the corresponding discharge pipe 12, and the screen holes on the surface of the screen assembly 16 are arranged from large to small from top to bottom;
[0028] The supporting mechanism includes a connecting plate 2, which is installed on the outside of the body shell 1. One end of the connecting plate 2 is fixedly connected to a mounting plate 21, and the other end of the connecting plate 2 is fixedly connected to a ring plate 22. The inner surface of the ring plate 22 is plugged and connected to a connecting cylinder 23, and the surface of the connecting cylinder 23 is fixedly connected to a feed trough 24. A through hole 25 is opened on the surface of the mounting plate 21, and the surface of the body shell 1 is fixedly connected to a side plate 26, and the surface of the side plate 26 is fixedly connected to a screw 27, and a nut 28 is installed on the surface of the screw 27. Under the action of the connecting plate 2, the mounting plate 21 and the ring plate 22 can be connected, and then the connecting cylinder 23 and the feed trough 24 can be installed on the ring plate 22.
[0029] Furthermore, the mounting plate 21 is mounted on the surface of the side plate 26, the inner diameter of the ring plate 22 is the same as the outer diameter of the connecting tube 23, the connecting tube 23 is plugged and connected to the inner surface of the feed port 11, and the feed groove 24 is abutted and connected to the surface of the ring plate 22. Through the action of the feed groove 24, the aperture range of rice is increased when it is poured into the device, thereby preventing the feed port 11 from having a small aperture, which causes the rice to scatter due to vibration when it is poured.
[0030] Furthermore, two groups of through holes 25 are provided, and the two groups of through holes 25 are opened on both sides of the mounting plate 21. Two groups of screws 27 are provided, and the two groups of screws 27 are installed on both sides of the side plate 26. The screws 27 pass through the through holes 25 and are connected to the surface of the mounting plate 21, and are more tightly connected to the surface of the mounting plate 21 through the side plate 26 when the mounting plate 21 is installed.
[0031] Furthermore, one end of the screw 27 is fixedly connected to the surface of the side plate 26, and the other end of the screw 27 is connected to the surface of the nut 28 through a thread. The screw 27 is plugged into the surface of the through hole 25, and the nut 28 is abutted against the surface of the mounting plate 21. The size of the nut 28 is larger than the size of the through hole 25. Under the connection between the screw 27 and the nut 28, the mounting plate 21 is fixed to the surface of the side plate 26, and then the connecting plate 2 is installed on the body shell 1.
[0032] Furthermore, an extension mechanism is provided on the surface of the discharge pipe 12, and the extension mechanism includes an extension tube 3, which is fixedly connected to the surface of the discharge pipe 12, a limiting hole 31 is provided on the surface of the extension tube 3, a sleeve 32 is sleeved on the outer surface of the extension tube 3, a socket 33 is provided on the surface of the sleeve 32, a fixing plate 34 is fixedly connected to the surface of the sleeve 32, a movable hole 35 is provided on the surface of the fixing plate 34, a pull rod 36 and a support spring 37 are movably connected to the inner surface of the fixing plate 34, and a support plate 38 is fixedly connected to the surface of the support spring 37. Under the action of the extension tube 3, further protection is achieved for the rice in the falling process, so as to avoid the random falling of the rice due to the vibration of the body shell 1 when falling, thereby avoiding the reduction of the screening productivity.
[0033] Furthermore, the diameter of the limiting hole 31 is the same as the diameter of the insertion hole 33, the inner diameter of the sleeve 32 is the same as the outer diameter of the extension tube 3, the diameter of the insertion hole 33 is the same as the diameter of the movable hole 35, and the cross-section of the fixed plate 34 is "U"-shaped. Both sides of the fixed plate 34 are fixedly connected to the surface of the sleeve 32. Under the action of the sleeve 32, the length of the extension tube 3 can be extended to adapt to the corresponding protection of rice falling from the discharge pipe 12 at different heights. The limiting holes 31 are distributed in a linear array on the surface of the extension tube 3.
[0034] Furthermore, the cross-section of the pull rod 36 is "T"-shaped, and the pull rod 36 is movably connected to the surfaces of the limiting hole 31, the insertion hole 33 and the movable hole 35. One end of the support spring 37 is fixedly connected to the inner surface of the fixed plate 34, and the other end of the support spring 37 is fixedly connected to the surface of the support plate 38. The support plate 38 is abutted against the surface of the sleeve 32. The pull rod 36 is connected to the surfaces of the extension tube 3, the sleeve 32 and the fixed plate 34 through the limiting hole 31, the insertion hole 33 and the movable hole 35, thereby limiting the connection between the extension tube 3 and the sleeve 32. Under the action of the support spring 37, a supporting force is applied to the support plate 38, so that the support plate 38 abuts against the outer surface of the sleeve 32, thereby making the connection between the pull rod 36 and the insertion hole 33 and the limiting hole 31 more secure.
[0035] Working principle: Before pouring rice, first install the mounting plate 21 on the side plate 26, so that the screw 27 is inserted into the through hole 25 and penetrates the mounting plate 21, and then the nut 28 is threadedly connected to the screw 27 and abuts against the surface of the mounting plate 21, so as to achieve the installation of the connecting plate 2 on the body shell 1. At this time, the ring plate 22 is located just above the feed port 11, and the connecting tube 23 is inserted into the ring plate 22 and located in the feed port 11, and then the feed trough 24 abuts against the upper surface of the ring plate 22, and the rice is poured into the feed trough 24 and enters the body shell 1 along the connecting tube 23, so that the diameter of the rice poured in can be increased.
[0036] The sieved rice will be discharged from the discharge pipe 12. The position of the sleeve 32 on the extension tube 3 must be adjusted according to the height of the discharge pipe 12 and the height of the collecting device so that the rice will not be scattered outside when discharged. When adjusting, first pull the pull rod 36 to make it slide along the surface of the insertion hole 33 and the movable hole 35 to cancel the plug-in effect with the limiting hole 31, and drive the support plate 38 to slide on the fixed plate 34, while the support spring 37 is in a compressed state. At this time, slide the sleeve 32 along the extension tube 3 and adjust its position so that the insertion hole 33 and the limiting hole 31 at the corresponding position are aligned, and then release the pull rod 36, so that the support plate 38 is re-adapted to the sleeve 32 under the action of the supporting force applied by the support spring 37, and the pull rod 36 is inserted into the limiting hole 31 at the corresponding position, thereby realizing the limit adjustment of the sleeve 32.
