Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0021] Please see Figure 1-4 This utility model provides a technical solution: a roller-scraping type jujube picking device, including a scraping device 1, a lifting device 2, a rotary roller device 3, a contour wheel 4, a contour wheel fixing plate 5, and a contour adjusting rod 6. The scraping device 1 is located in the middle of the lifting device 2. The rotary roller device 3 is bolted to the bottom of the front end of the scraping device 1. The contour adjusting rod 6 is welded to the top of the contour wheel fixing plate 5 and is bolted to both sides of the front interior of the scraping device 1. The contour wheel 4 is rotatably connected to the interior of the contour wheel fixing plate 5.
[0022] In this embodiment, the use of the contour wheel 4 and the contour adjustment rod 6 not only adapts to undulating terrain, but also allows for the adjustment of the device's operating parameters at any time by adjusting the contour adjustment rod 6, improving the adaptability to the working environment. Furthermore, the rotary drum device 3 provides an active thrust to the jujubes after they have been collected on the ground, making it easier for the jujubes to accumulate and climb along the comb tooth 18 structure in the scraper device 1. This eliminates the need for the jujubes to passively accumulate and climb under the forward action of the comb tooth 18, reducing the depth of the comb tooth 18 into the soil and effectively alleviating the soil accumulation phenomenon during the picking process.
[0023] As a technical optimization of this utility model, the scraping device 1 includes a pickup side plate 11, a strip brush drive shaft 12, a pickup side plate fixing shaft 13, a comb tooth fixing plate 14, a bearing seat 15, a strip brush driven shaft 16, a strip brush 17, comb teeth 18, a driven sprocket 19, a pickup side plate sleeve 110, a double-ear chain 111, and a drive sprocket 112. The pickup side plate 11 is fixed to the surfaces at both ends of the pickup side plate fixing shaft 13. The comb tooth fixing plate 14 is welded to the side of the pickup side plate 11 closest to its inner wall. The comb teeth 18 are evenly distributed between the two pickup side plates 11 at intervals and welded to the top of the comb tooth fixing plate 14. The bearing seats 15 are respectively bolted... The front and rear sides of the pickup side plate 11 are connected to each other. The two ends of the strip brush drive shaft 12 are set inside the two bearing seats 15 on the rear side. The two ends of the strip brush driven shaft 16 are set inside the two bearing seats 15 on the front side. The drive sprocket and the driven sprocket 19 are respectively sleeved on the surface of the strip brush drive shaft 12 and the strip brush driven shaft 16. The double-ear chain 111 is engaged between the surfaces of the drive sprocket 112 and the driven sprocket 19 on the front and rear sides. The strip brush 17 is bolted to the surface of the double-ear chain 111. The pickup side plate sleeve 110 is welded to the front side of the extended end of the pickup side plate 11. The pickup side plate sleeve 110 is bolted to the surface of the contour adjustment rod 6.
[0024] In this embodiment: by setting up a scraping device 1, the active sprocket 112 can be driven to rotate by the active shaft 12 of the strip brush, which in turn drives the double-ear chain 111 to rotate, thereby driving the driven sprocket 19 and the driven shaft 16 of the strip brush to rotate. Therefore, the strip brush 17, which rotates synchronously with the double-ear chain 111, can perform a secondary combing of the red dates that climb up along the comb teeth 18, picking up the red dates. The sand between the red dates will fall from the gaps between the comb teeth 18 under the action of the strip brush 17, leaving the red dates to be picked up, achieving the effect of automatically picking up the fallen red dates, reducing harvesting costs and improving work efficiency.
[0025] As a technical optimization of this utility model, the lifting device 2 includes a lifting frame 21, a fixed base 22, a lifting cylinder 23, and a lifting rod 24. The fixed base 22 is welded to the top and bottom of the inner wall of the lifting frame 21, respectively. One end of the lifting rod 24 is hinged to the inside of the two top fixed bases 22, and the tail end of the lifting cylinder 23 is hinged to the inside of the two bottom fixed bases 22. The telescopic end of the lifting cylinder 23 is hinged to the lifting rod 24.
[0026] In this embodiment: by setting up the lifting device 2, the extension or retraction of the extension end of the lifting cylinder 23 can drive the lifting rod 24 to rotate around the fixed base 22 as the fulcrum, thereby adjusting the soil entry angle and soil entry depth parameters of the comb teeth 18, effectively alleviating the soil accumulation phenomenon during the picking process.
[0027] As a technical optimization of this utility model, the fixed base 22 is symmetrically distributed on the left and right with the vertical plane in the middle of the lifting frame 21 as the symmetry plane, and the lifting rod 24 is set in an H shape and is symmetrically distributed on the left and right with the vertical plane in the middle of the lifting frame 21 as the symmetry plane.
[0028] In this embodiment: by setting the fixed base 22 with the vertical plane in the middle of the lifting frame 21 as the plane of symmetry and symmetrically distributed on the left and right, the stability of the lifting rod 24 during operation can be achieved. By setting the lifting rod 24 to be H-shaped as a whole and symmetrically distributed on the left and right with the vertical plane in the middle of the lifting frame 21 as the plane of symmetry, the structural strength of the lifting rod 24 can be improved, thereby ensuring the stability of the structure during the picking process.
[0029] As a technical optimization of this utility model, the rotary drum device 3 includes a drum brush adjusting plate 31, a drum brush shaft 32, a drum brush 33, and a bearing 34. The drum brush adjusting plate 31 is bolted to the side of the extended end of the pickup side plate 11. The bearing 34 is bolted to the opposite side of the two drum brush adjusting plates 31. The two ends of the drum brush shaft 32 are located inside the two bearings 34. The drum brush 33 is bolted to the surface of the drum brush shaft 32, and the drum brushes are evenly distributed on the surface of the drum brush shaft 32.
[0030] In this embodiment: by setting a rotary roller device 3, the roller brush 33 can be driven to rotate by the roller brush shaft 32, which can push the jujubes that have been collected and piled up on the ground, so that the jujubes actively climb up along the comb teeth 18, no longer relying on the passive accumulation and climbing of the jujubes under the action of the comb teeth 18, which can reduce the depth of the comb teeth 18 into the soil and effectively alleviate the soil accumulation phenomenon during the picking process.
[0031] As a technical optimization of this utility model, the lifting rod 24 is bolted to the side of the roller brush adjusting plate 31.
[0032] In this embodiment: by setting the lifting rod 24 to be bolted to the roller brush adjustment plate 31, it is convenient to adjust the parameters of the angle of the comb teeth 18 entering the soil and the depth of the comb teeth 18 entering the soil by the lifting cylinder 23, so as to achieve the effect of flexible operation.
[0033] As a technical optimization of this utility model, the driving sprocket 112 is symmetrically distributed on the surface of the brush driving shaft 12, and the driven sprocket 19 is symmetrically distributed on the surface of the brush driven shaft 16.
[0034] In this embodiment, by setting the driving sprocket 112 and the driven sprocket 19 to be symmetrically distributed on the surfaces of the driving shaft 12 and the driven shaft 16 of the brush, the stability of the brush 17 during operation can be achieved.
[0035] Working principle: First, the jujubes, after being manually collected, are piled on the ground. Before operation, the height of the contouring wheel 4 is adjusted by adjusting the height of the contouring adjustment rod 6 within the picking side sleeve 110. The extension or retraction of the lifting cylinder 23 causes the lifting rod 24 to rotate around the fixed base 22, adjusting the soil entry angle and depth of the comb teeth 18. After the operating parameters are adjusted, the roller brush 33, under the action of the roller brush shaft 32, rotates, sweeping the piled jujubes towards the comb teeth 18. Under the active action of the roller brush 33, the dates accumulate and climb along the comb teeth 18. At the same time, the brush drive shaft 12 on the scraping device 1 drives the drive sprocket 112 to rotate, which in turn drives the double-ear chain 111 to rotate, thereby driving the driven sprocket 19 and the brush driven shaft 16 to rotate. Therefore, the brush 17, which rotates synchronously with the double-ear chain 111, can perform a secondary brushing on the dates that climb along the comb teeth 18, picking up the dates. The sand between the dates will fall through the gaps between the comb teeth 18 under the action of the brush 17, leaving the dates to be picked up, thus completing the automatic picking up of the fallen dates.
[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
