DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0019] Embodiment, please refer to Figures 1-4The utility model provides a cyperus esculentus lifting screen device, including frame 1, the frame 1 is installed with the chain mechanism 2 of inclination, the chain mechanism 2 includes at least two circulative rotation chain 21, its high end direction is rear, and its low end direction is front, to convey the mixture of bean soil of cyperus esculentus from low end to high end, namely the mixture of bean soil is transported from front to rear, be equipped with the connecting lug 22 of interval uniform distribution on chain 21, still include a plurality of chain plates 3, every chain plate 3 includes bottom plate 31 and the right angle plate 4 of fixed connection in the both ends of bottom plate 31, the two right angle plate 4 of chain plate 3 is detachably connected through bolt assembly with the connecting lug 22 on two chain 21, the front end of bottom plate 31 is fixedly provided with the push plate portion 32 of bending upwards, and its rear end is provided with the baffle portion 33 of bending downwards, and its surface is equipped with the long round hole 34 of interval uniform distribution, the width of long round hole 34 is less than the fruit diameter of cyperus esculentus, the both ends of push plate portion 32 and baffle portion 33 are sealed fixedly connected with two right angle plate 4, the gap between adjacent two chain plate 3 is less than the fruit diameter.

[0020] When working, chain plate 3 circulates with chain 21. Push plate portion 32 plays a role in lifting the mixture of bean soil. Baffle portion 33 plays a role in sealing the gap between two chain plates 3 when chain plate 3 is turned over at one end of chain 21, avoiding fruit leakage. Long round hole 34 is a sieve hole, which screens out soil and retains cyperus esculentus. Thus, while lifting the mixture of bean soil, the function of screening soil is achieved. Since the two ends of the sieve plate are detachable, when a certain chain plate 3 is deformed or damaged, it can be replaced individually, saving cost and maintenance time, and thus improving work efficiency. Push plate portion 32 and baffle portion 33 of chain plate 3 play a sealing role while also playing a role in reinforcing bottom plate 31, which improves the stiffness of bottom plate 31, reduces deformation, and makes the lifting screen work more reliable and has a low failure rate.

[0021] Among them, a drive shaft 23 for driving the chain 21 to circulate is arranged at the high end of the chain mechanism 2, one end of the drive shaft 23 is connected with a hydraulic motor 6 fixedly arranged on the frame 1 through a first chain transmission device 5, for driving the chain 21 to circulate through the hydraulic motor 6. It can be seen that the lifting screen has a built-in driving device, compact structure and convenient use.

[0022] The driving shaft 23 is connected with the first vibrating shaft assembly 7 located in the middle of the chain 21 through the second chain transmission device 71, and is used to drive the first vibrating shaft assembly 7 to rotate. The vibrating shaft of the first vibrating shaft assembly 7 is installed on the rack 1, and a triangular support frame 72 is fixedly connected to the vibrating shaft. A rotatable roller 73 is installed at each corner of the triangular support frame 72, and is used to drive the three rollers 73 to successively push the chain 21 passing above the triangular support frame 72 when the vibrating shaft assembly rotates, so as to make the chain plate 3 vibrate. The soil and bean mixture is vibrated by the first vibrating shaft assembly 7, which can break large soil blocks and improve the soil screening effect, and can also avoid the long circular hole 34 from being blocked by vibration.

[0023] The second vibrating shaft assembly 8 is further included, and the second vibrating shaft assembly 8 is connected with the first vibrating shaft assembly 7 through the third chain transmission device 81, and is used to drive the second vibrating shaft assembly 8 to rotate. The second vibrating shaft assembly 8 is provided with the same triangular support frame 72 and the roller 73 as the first vibrating shaft assembly 7. It can be seen that the effect of vibrating and screening soil is improved by the two vibrating shaft assemblies.

[0024] The straight plate 4 includes a vertical plate 41 and a horizontal plate fixedly connected to the top end of the vertical plate 41. The horizontal plate is provided with a connecting hole 44, which is used to connect the connecting lug 22 through a bolt assembly. The two ends of the push plate part 32 and the baffle part 33 are respectively welded with two vertical plates 41 to be sealingly and fixedly connected.

[0025] In order to increase the conveying capacity and expand the conveying area, the chain mechanism 2 includes three chain 21, and the chain 21 located in the middle is equally spaced from the chain 21 on both sides, which is used to form two identical chain plate installation areas on both sides of the chain 21 located in the middle. The chain plates 3 installed in the two chain plate installation areas are symmetrical left and right with the chain 21 located in the middle as a reference. The horizontal plates at the two ends of the chain plate 3 are long and short, which are long horizontal plate 43 and short horizontal plate 42 respectively. The short horizontal plate 42 is connected with the chain 21 located in the middle, and the long horizontal plate 43 is connected with the chain 21 on the outside. It can be seen that the conveying area is expanded, the conveying efficiency is improved, but the length of the chain plate 3 is retained. By symmetrically installing two identical chain plates 3, the length of each chain plate 3 is reduced, the stiffness is improved, the deformation is reduced, and the reliability is still good. In addition, the two symmetrical chain plates 3 reduce the types of chain plates 3, so that the same chain plate 3 is used in the whole lifting and screening, which is convenient for manufacturing, storage, maintenance and replacement, and further reduces the cost.

[0026] In order to improve the sealing performance and prevent fruit leakage, a plurality of cover plates 24 are further included. The cover plate 24 covers above a pair of adjacent short horizontal plates 42, and is connected with the chain 21 through the bolt assembly, which is used to seal the gap between the pair of adjacent short horizontal plates 42.

[0027] In order to further improve the versatility, the connecting ears 22 on the chain 21 are divided into multiple pairs, and each pair of the connecting ears 22 is located on both sides of the chain 21; each pair of the connecting ears 22 of the middle chain 21 is connected to the short cross plates 42 of two chain plates 3; and each pair of the connecting ears 22 of the outer chain 21 is connected to the long cross plate 43 of one chain plate 3 through two bolt assemblies. As can be seen, the three chains 21 are the same chain 21, which improves the versatility of the chain 21, provides convenience for manufacturing, materials, maintenance and replacement, and reduces the cost.

[0028] The embodiment has the advantages that the chain plate 3 is arranged as a conveying device for conveying the soil mixture, the soil mixture is lifted and the soil particles are efficiently screened at the same time, the operation is reliable, the cost is low, the maintenance is convenient, and the clogging is prevented, and the harvesting efficiency of the cyperus is improved.

[0029] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
