Abstract
Description
Technical Field
[0001] This utility model relates to an agricultural device, or more precisely, a device for collecting fallen jujubes. Background Technology
[0002] Currently, the collection of fallen jujubes mainly relies on manual labor or the use of pneumatic suction collection equipment. Manual collection typically begins with workers using rakes to gather the fallen jujubes into piles or strips, then using tools to pick them up from the ground. When using pneumatic suction collection equipment, workers first use rakes to gather the fallen jujubes into strips, or use a blower to gather them, then manually hold the suction hose, aim it at the gathered strips of jujubes, and use the blower's suction to suck the jujubes, along with any impurities, into the collection machine. Manual collection is labor-intensive and inefficient; pneumatic suction collection is slow, inefficient, and requires multiple people working together. Utility Model Content

[0015] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0016] like Figure 1 As shown, the jujube-collecting device includes a vehicle chassis 1. The head of the vehicle chassis 1 is provided with a collection unit 3 and a picking unit 2. The collection unit 3 is connected to the picking unit 2 via a four-bar linkage 5 hinged to the collection mechanism. The picking unit 2 is connected to the vehicle chassis 1 via a four-bar linkage 4 hinged to the picking mechanism. The side of the vehicle chassis 1 is provided with a collection and transportation system 6, which cooperates with the picking unit 2.
[0017] like Figures 2 to 5 As shown, the picking unit 2 includes a housing 20, inside which is a jujube-picking rack 25. The jujube-picking rack 25 is provided with a plurality of jujube-picking devices 23 arranged in a ring. The jujube-picking devices 23 are connected in series by a chain 24. A dial motor 22 is provided on one side of the jujube-picking rack 25, which drives the chain 24. A throwing guide device 21 is provided on the outer side of the chain 24. The throwing guide device 21 cooperates with the jujube-picking devices 23. A pair of second ground wheel adjustment devices 27 are provided at the head of the jujube-picking rack 25. A second ground wheel 26 is provided on the second ground wheel adjustment device 27.
[0018] It should be noted that the height of the second ground wheel 26 can be adjusted by the second ground wheel adjustment device 27, thereby ensuring that the contact distance between the date picker 23 and the ground is within the normal operating range.
[0019] like Figure 4 As shown, the material throwing guide device 21 is arc-shaped, the inlet 211 of the material throwing guide device 21 is in contact with the ground, and the outlet 212 of the material throwing guide device 21 is higher than the receiving end of the collection and transportation system 6.
[0020] The material throwing guide device 21 has an upper support shaft 213 on the side of its outlet 212, which is hinged to the date-picking frame 25. The material throwing guide device 21 also has a lower support shaft 214 on the side of its inlet 211, which is hinged to the lower end of a spring rod 215. The upper end of the spring rod 215 passes through a pre-drilled hole in the date-picking frame 25 and is locked by a fixing nut 218, the size of which is larger than the diameter of the pre-drilled hole in the date-picking frame 25. A stop pin 217 is provided in the middle of the spring rod 215, and a spring 216 is sleeved on the spring rod 215, with the lower end of the spring 216 abutting against the stop pin 217.
[0021] Under the force of the spring 216, the inlet 211 is pushed into contact with the ground. When the operation encounters uneven ground, the inlet 211 can follow the undulations of the ground and maintain close contact, ensuring that the red dates on the ground can be reliably swept and enter the throwing guide device 21 from the inlet 211.
[0022] In addition, the material guiding device 21 is provided with several parallel through-holes 210. The width of the mesh 210 is designed to be smaller than the diameter of the jujube, typically 20% to 80% of the jujube's diameter, allowing collected soil and twigs to pass through while preventing the jujube from leaking out. Of course, the mesh 210 can be strip-shaped or have other openwork structures to ensure that mud and sand can pass through while preventing the jujube from leaking out.
[0023] In addition, the jujube-picking device 23 includes a jujube-picking plate 231, the edge of which is provided with a plurality of picking teeth 232. The picking teeth 232 are made of soft rubber or bristles, or other flexible materials, and can flexibly deform and conform to the ground when sliding on uneven ground, ensuring that the jujubes on the ground are picked and swept into the throwing guide device 21.
[0024] like Figure 6 As shown, the strip unit 3 includes a transverse support 39 arranged in the middle. A pair of first ground wheel adjustment devices 37 are provided in the middle of the transverse support 39. A first ground wheel 36 is provided at the bottom of the first ground wheel adjustment device 37. Rotary strip devices 310 are provided at both ends of the transverse support 39.
[0025] It should be noted that the height of the first ground wheel 36 can be adjusted via the first ground wheel adjustment device 37.
[0026] The rotary strip device 310 includes a sweeping disc folding device 33. The end of the sweeping disc folding device 33 is provided with a sweeping disc adjusting device 34. The sweeping disc adjusting device 34 is provided with a sweeping disc motor 35. The output shaft of the sweeping disc motor 35 is provided with a sweeping disc 32. The circumferential edge of the sweeping disc 32 is provided with a plurality of gathering bands 31.
[0027] The working principle of the device for collecting fallen jujubes is explained below.
[0028] During operation, a pair of rotary strip devices 310, driven by a sweeping disc motor 35, have their sweeping discs 32 rotating in opposite directions. The sweeping discs 32 drive the gathering belt 31 to rotate, and the gathering belt 31 sweeps the jujubes scattered on the ground towards the middle of the two rotary strip devices 310. Driven by the self-propelled vehicle chassis 1, the rotary strip devices 310 rotate continuously to sweep and gather, achieving continuous strip collection.
[0029] As the machine moves forward, the jujubes that have been collected in the aforementioned collection unit are pushed by the rotation of the multi-row toothed jujube pusher 23 and concentrated at the inlet of the throwing guide device 31. Then, they are thrown into the collection and transportation system 6 through the arc surface of the throwing guide device 31.
[0030] This jujube-collecting device can complete the jujube strip collection and jujube-collecting operations in one go, greatly reducing the problems of large labor requirements, need for prior strip collection, and high requirements for the width of the jujube strips in air suction picking technology.
[0031] The ground jujube picking device can be used directly to pick up jujubes that have already been collected without the collection strip unit 3. Compared with the air suction picking technology, it can greatly reduce the requirements of the air suction picking technology on the width of the jujube collection strip, reduce auxiliary manpower, improve work efficiency, and can meet the condition of jujube collection strip width of 1.5m for picking operations.
[0032] Obviously, the embodiments described above are only some embodiments of this application, and not all embodiments. The accompanying drawings show preferred embodiments of this application, but do not limit the patent scope of this application.
