[0004] However, in the above device, the entire collecting mechanism is driven by a hydraulic rod with the help of an adjusting rod, so as to adjust the collecting height and collecting angle. However, the adjustment range of this adjustment method is limited, and the terrain of the yam planting area is undulating, and there are obvious differences in the growth depth and angle of the yam. This limited adjustment range may not allow the collecting mechanism to accurately reach the location of the yam, thereby affecting the harvesting effect.

[0005] In view of the differences in soil conditions, softer or more compact soils require greater adjustments to the harvesting height and angle. Therefore, this limited adjustment range restricts the effective application of the yam seedling harvesting device in different types of soils to a certain extent. Utility Model Content

DETAILED DESCRIPTION

[0029] like Figure 1-5 As shown, a collecting mechanism for a yam seedling harvesting device comprises a collecting grid 1 obliquely arranged at the rear end of a machine body, an eccentric shaft 2 is horizontally arranged above the collecting grid 1, two ends of the eccentric shaft 2 are rotatably connected to the machine body through bearing seats, two eccentric bearing groups are symmetrically fixedly sleeved on the eccentric shaft 2 near the two ends thereof, the eccentric bearing group consists of two eccentric bearings, a sleeve 4 is fixedly sleeved on the outer side of the eccentric bearing group, an oiling nozzle 5 is arranged on the outer side wall of the sleeve 4 between the two eccentric bearings 3, a first height adjustment rod 6 is fixedly connected to the bottom of the sleeve 4, the other end of the first height adjustment rod 6 is rotatably connected to the collecting grid 1, and second height adjustment rods 7 are symmetrically rotatably arranged on both sides of the collecting grid 1 near the front end thereof, and the other end of the second height adjustment rod 7 is fixedly connected to the machine body.

[0030] During specific use, when harvesting yam seedlings, the staff first adjusts the length of the first height adjustment rod 6 and the second height adjustment rod 7 according to the terrain of different yam planting sites, the growth depth and angle of the yam, and the soil conditions, so that the collecting grid 1 can collect the yam seedlings at a suitable height and angle.

[0031] After the adjustment is completed, the yam seedling harvesting device is started. At this time, the eccentric shaft 2 rotates under the drive of external power. Since an eccentric bearing group is arranged on the eccentric shaft 2, when the eccentric shaft 2 rotates, it will drive the sleeve 4 sleeved on the outside of the eccentric bearing group to do up and down reciprocating motion. The bottom of the sleeve 4 is rotatably connected with the collecting grid 1 through the first height adjustment rod 6. The up and down motion of the sleeve 4 is converted into a push-pull action on the rear end of the collecting grid 1, so that the rear end of the collecting grid 1 swings up and down. At the same time, the second height adjustment rods 7 on both sides of the front end of the collecting grid 1 play a role of stability and auxiliary support.

[0032] With this design, firstly, by setting the first height adjusting rod 6 and the second height adjusting rod 7, the position and angle of the collecting grid 1 can be flexibly adjusted according to the terrain of different yam planting sites, the growth depth and angle of the yam and the soil conditions, so as to adapt to various complex working environments, and enable the collecting grid 1 to contact the yam seedlings more accurately, reduce damage to the yam seedlings, and ensure that the harvested yam seedlings are complete and of good quality.

[0033] Secondly, the oiling nozzle 5 provided on the sleeve 4 facilitates lubrication and maintenance of the internal structure, reduces component wear, prolongs service life, and reduces maintenance costs and downtime.

[0034] The first height adjustment rod 6 and the second height adjustment rod 7 arranged front and back again enable the collecting grid 1 to maintain balance and stability during operation, reduce shaking and vibration, and improve the accuracy of harvesting.

[0035] The first height adjustment rod 6 includes two mounting plates 61 symmetrically fixed at intervals on the bottom of the sleeve 4 , and a plurality of first positioning holes 62 are formed on the mounting plates 61 at even intervals along the height direction thereof.

[0036] A connecting plate 63 is slidably disposed between the two mounting plates 61 , and a connecting seat 66 is fixedly connected to the other end of the connecting plate 63 , and the connecting seat 66 is rotatably connected to the collecting grid 1 .

[0037] The connecting plate 63 is provided with a plurality of first adjustment holes 64 at equal intervals along the height direction thereof, wherein two first adjustment holes 64 and their corresponding first positioning holes 62 are respectively provided with the same first positioning pin shaft 65 .

[0038] With this design, when the height of the collecting grid 1 needs to be adjusted, the staff can slide the connecting plate 63 up and down between the mounting plates 61 to align one of the first adjustment holes 64 with the corresponding two first positioning holes 62, and then pass the first positioning pin 65 through the aligned first adjustment hole 64 and the first positioning hole 62, thereby fixing the connecting plate 63 at the current position.

[0039] By selecting the first adjustment hole 64 at different positions to cooperate with the first positioning hole 62, the height of the collecting grid 1 can be adjusted. In this way, when facing the terrain of different yam planting sites, the growth depth and angle of yam and the soil conditions, the height of the collecting grid 1 can be flexibly adjusted so that the collecting grid 1 can collect the yam seedlings at a suitable height and angle, thereby improving the adaptability of the harvesting device to various complex situations and ensuring the quality and efficiency of the yam seedling harvest.

[0040] The second height adjustment rod 7 comprises a fixing sleeve 71 , and fixing plates 72 are symmetrically arranged on both sides of the fixing sleeve 71 , and the fixing plates 72 are connected to the machine body through a plurality of bolts.

[0041] A fixing rod 73 is slidably disposed in the fixing sleeve 71 , and the bottom end of the fixing rod 73 is rotatably connected to the collecting grid 1 .

[0042] The fixing sleeve 71 is provided with a second positioning hole, and the fixing rod 73 is provided with a plurality of second adjustment holes 74 at equal intervals along the height direction thereof.

[0043] The second positioning hole and the corresponding second adjustment hole 74 are provided with a second positioning pin 75 .

[0044] With this design, when the height of the front end of the collecting grid 1 needs to be adjusted, the staff makes the fixing rod 73 slide up and down in the fixing sleeve 71. When one of the second adjustment holes 74 on the fixing rod 73 is aligned with the positioning hole on the fixing sleeve 71, the second positioning pin 75 is inserted into the aligned positioning hole and the second adjustment hole 74, thereby fixing the position of the fixing rod 73.

[0045] By selecting the second adjustment hole 74 at different height positions to cooperate with the second positioning hole, the length of the fixing rod 73 extending out of the fixing sleeve 71 can be changed, thereby realizing the adjustment of the height of the front end of the collecting grid 1. In this way, the height of the front end of the collecting grid 1 can be flexibly adjusted according to actual conditions, such as the terrain of the yam planting site, the growth conditions of the yam and the soil conditions, so that the collecting grid 1 can collect the yam seedlings in the best posture and angle, thereby ensuring the quality and efficiency of the harvest.

[0046] The collecting grid 1 includes two side plates 11 symmetrically spaced apart, and a front blade 12 is fixedly connected between the two side plates 11 and at the front end thereof.

[0047] A plurality of support rods 13 are fixedly connected between the two side plates 11 , a plurality of thin rods 14 are evenly spaced at the top of the support rods 13 along the length direction thereof, and one end of the thin rods 14 is fixedly connected to the back of the front blade 12 .

[0048] The two side plates 11 are respectively provided with a plurality of connection holes 15 symmetrically and evenly spaced apart. The connection seat 66 is provided with a fixing hole penetrating therethrough. The fixing hole and the corresponding connection hole 15 are provided with the same third positioning pin shaft 16 .

[0049] With this design, the two side panels 11 serve to support and fix other components, and the front shovel 12 at the front end is used to insert into the soil first and initially shovel up the yam seedlings during harvesting; multiple support rods 13 serve to enhance the stability of the structure, and multiple thin rods 14 evenly spaced at the top help to comb and collect the yam seedlings.

[0050] When adjusting the position of the collecting grid 1, the fixing holes on the connecting plate 63 are aligned with the corresponding connecting holes 15 on the side plate 11, and then the third positioning pin 16 is passed through to achieve the connection and fixation of the connecting plate 63 and the side plate 11. By selecting the connecting holes 15 at different positions to cooperate with the fixing holes, the connection position of the collecting grid 1 and the first height adjustment rod 6 can be adjusted, thereby changing the angle and height of the collecting grid 1 to adapt to different harvesting conditions.

[0051] For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the protection scope of the present invention.
