Description

Technical Field

[0001] The utility model relates to the technical field of forage harvesting agricultural machinery, in particular to a picking structure and a baler. Background Art

[0002] like Figure 1 As shown, a conventional baler picks up grass by means of a plurality of spring teeth of the same type mounted on a picking beam. When the baler is operating, the picking beam is rotated by the power transmitted from the baler, thereby driving the spring teeth to rotate to pick up grass. The above structure is only applicable to picking up grass on relatively flat land. When operating on a land with ridges and ridges of fixed height, the grass in the ridges cannot be picked up.

[0003] In the prior art, there is a technology that uses rollers to detect the height of the terrain, and then adjusts the relative angle between the spring teeth and the picking roller through the hydraulic oil circuit to control the distance between the spring teeth and the ground, so as to meet the needs of picking up grass in different terrains. However, there are the following problems:

[0004] 1. The roller profile detection technology is used to detect the height of the terrain. When facing some hard or dense straw, the roller will run over the straw and misjudge the straw in the area as the ground, causing the risk of missing it.

[0005] 2. The hydraulic oil circuit is used to adjust the angle of the spring teeth relative to the pickup roller. The hydraulic oil circuit system has a hysteresis in its response, which will affect the normal picking effect.

[0006] 3. The spring teeth can be adjusted in different states by adjusting the angle between the spring teeth and the pickup roller to meet the needs of picking up grass in furrows and ridges. Among them, the angle of the spring teeth relative to the pickup roller has a huge impact on the picking effect in actual applications. That is, after the spring teeth angle is set relative to the overall posture of the machine, if it changes, it will cause the grass to fall forward when picking up, or the grass will be stuck after picking up, and the grass will be taken out.

[0007] 4. The installation method of the above-mentioned spring teeth is an integral assembly type. In the process of picking up grass, the working conditions are complicated. Since the spring teeth are easily damaged due to frequent picking up of grass, the spring teeth need to be replaced frequently. Usually, a nut is welded inside the picking beam, and the spring teeth are installed on the picking beam by bolts. This installation method is inefficient and difficult to replace the spring teeth. In particular, when the nut inside the picking beam is damaged, the spring teeth cannot be installed, thereby affecting the function of the entire baler. Utility Model Content

[0041] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present utility model can be combined with each other.

[0042] like Figures 2 to 4 As shown, the utility model discloses a picking structure, which includes a picking beam 1, a plurality of groups of contoured spring teeth 2, and a quick-release assembly 3. The picking beam 1 is arranged on the baler, and the picking beam 1 is rotatably connected to the baler. Here, the connection method between the picking beam 1 and the baler can be set by a person skilled in the art according to the existing technical means in the field, so it will not be introduced in detail. The picking beam 1 includes a plurality of fixed plates 11, and a plurality of grooves are constructed on the picking beam 1, and the plurality of grooves are arranged along the longitudinal direction of the picking beam 1. The fixing plate 11 is concave to form a groove 12, and a plurality of fixing holes 15 are constructed at the bottom of the groove 12 of the fixing plate 11. A plurality of mounting holes 13 are constructed on one side of the fixing plate 11 along its length direction, and the plurality of mounting holes 13 are located on one side of the groove 12. The fixing plate 11 is arranged in the groove of the picking beam 1, and the fixing plate 11 is fixed to the picking beam 1 by screws.

[0043] like Figures 2 to 5As shown, multiple groups of contour spring teeth 2 are detachably arranged in the groove 12 of the corresponding fixed plate 11. Multiple groups of contour spring teeth 2 are evenly arranged around the axis of the picking beam 1. The structure of each group of contour spring teeth 2 is the same. Each group of contour spring teeth 2 includes multiple spring teeth 21, and the multiple spring teeth 21 are arranged along the longitudinal direction of the fixed plate 11, and the multiple spring teeth 21 are all arranged in the groove 12 of the fixed plate 11. The spring teeth 21 are detachably connected to the fixed plate 11 through the quick release assembly 3. As shown in FIG. Figure 6 As shown, the elastic tooth member 21 includes an elastic spring 22 and at least two elastic teeth 24. The middle of the elastic spring 22 is bent to form a notch 23. The at least two elastic teeth 24 are respectively located at both ends of the elastic spring 22. When the elastic tooth member 21 is fixed in the groove 12 of the fixing plate 11, the quick release assembly 3 passes through the notch 23 of the elastic tooth member 21 and fixes the elastic tooth member 21 to the fixing plate 11.

[0044] Alternatively, if Figure 4 As shown, the fixing plate 11 is configured with a plurality of notches 14 on one side along its length direction, and the plurality of notches 14 are located on the side wall of the groove 12, and the plurality of notches 14 are respectively provided corresponding to a spring tooth 24. When the spring tooth member 21 picks up grass, and when the grass has a high density or contains hard debris such as gravel and soil, the spring teeth 24 of the spring tooth member 21 can be elastically deformed, thereby avoiding damage to the spring teeth 24, and when the spring teeth 24 are elastically deformed, the spring teeth 24 will enter the corresponding notches 14.

[0045] Alternatively, if Figure 5 , Figure 7As shown, in each group of contoured spring tooth groups 2, the heights of the multiple spring tooth pieces 21 are arranged in a wave shape. The contoured spring tooth group 2 includes a wave crest section 25 and a wave trough section 26 which are arranged in sequence and crosswise. In the utility model, the contoured spring tooth group 2 refers to a group of spring tooth clusters mounted on the picking beam 1, and the heights thereof are arranged in sequence according to the shapes of the ridges, furrows and terraces of the plots in the working area. The ridges and furrows refer to the shapes of the plots of land that are cultivated into a fixed wave shape by artificial tillage machinery to improve the ventilation and fertilization rate of the crop roots and stems, wherein the furrows are low-lying areas and the ridges and terraces are raised areas. The contoured spring tooth group is arranged on the picking beam, and the height of the contoured spring tooth group is arranged in a wave shape according to the furrows and ridges, so that the spring teeth of the contoured spring tooth group can be more closely fitted to the ground at the ridges and terraces, and the grass at the furrows can be effectively picked up to avoid missing. For example, when baling, the baler inputs power from the shaft end of the pick-up beam to drive the pick-up beam to rotate, and the multiple groups of contour spring teeth mounted on the pick-up beam rotate along with the pick-up beam. At the same time, the pick-up beam rotates along with the baler in the direction of travel. At this time, the grass on the ridge is picked up by the spring teeth in the contour spring tooth group located in the trough section 26 area, and the grass in the ditch is picked up by the spring teeth in the contour spring tooth group located in the peak section 25 area. Under the action of the pick-up beam, the grass on the ditch and the ridge is picked up, lifted, and thrown backwards at the same time, and enters the forming chamber of the whole machine to complete the baling.

[0046] like Figure 3 , Figure 8 , Fig. 9 As shown, the quick release assembly 3 includes a quick release support tube 31, a top buckle 32, at least one spring piece 33, and a top support spring 34. A limiting edge 311 is constructed at one end of the quick release support tube 31, and the limiting edge 311 is arranged along the outer surface of the quick release support tube 31. The other end of the quick release support tube 31 is sealed, and a through hole 312 is arranged at the bottom of the barrel cavity of the quick release support tube 31. At least one clamping hole 313 is constructed on the quick release support tube 31, and the barrel cavity of the quick release support tube 31 is connected to the outside through the clamping hole 313. The top buckle 32 is cylindrical, and a pressing cap 321 is constructed at one end of the top buckle 32, and a pressing groove 322 is constructed on the pressing cap 321 to facilitate pressing the top buckle 32. At least one spring piece 33 is disposed on the top buckle 32 , one end of the spring piece 33 is connected to the top buckle 32 , the other end of the spring piece 33 is disposed toward the pressing cap 321 of the top buckle 32 , and the spring piece 33 forms an angle with the axis of the top buckle 32 .

[0047] When in use, the top support spring 34 is sleeved on the end of the top buckle 32 away from its pressing cap 321, and one end of the top support spring 34 abuts against the connection between the spring piece 33 and the top buckle 32. Then, the top buckle 32 is inserted into the quick-release support tube 31. At this time, the spring piece 33 undergoes elastic deformation, and the end of the spring piece 33 close to the pressing cap 321 approaches the top buckle 32, and the included angle becomes smaller or disappears, so that the top buckle 32 can enter the barrel cavity of the quick-release support tube 31 more smoothly. When the top buckle 32 enters the barrel cavity of the quick-release support tube 31 as a whole, the end of the top buckle 32 away from its pressing cap 321 enters the through hole 312. At this time, the top support spring 34 is located between the barrel bottom of the quick-release support tube 31 and the top buckle 32, and the top support spring 34 is in a compressed state. At the same time, the spring piece 33 enters the locking hole 313 of the quick-release support tube 31 , and the spring piece 33 returns to the original state, and the angle between the spring piece 33 and the top buckle 32 returns to the original angle.

[0048] Optionally, not shown in the figure, the number of the locking hole 313 is one, and the number of the spring piece 33 is also one, and the connection between the top buckle 32 and the quick-release support tube 31 is achieved by arranging the spring piece 33 in the locking hole 313. When the number of the locking hole 313 and the spring piece 33 are both one, the top buckle 32 needs to be rotated to achieve the purpose of the spring piece 33 entering the locking hole 313 for locking.

[0049] Alternatively, if Fig. 9 As shown, there are two locking holes 313 and one spring piece 33, and the connection between the top buckle 32 and the quick-release support tube 31 is achieved by arranging the spring piece 33 in the locking holes 313. When the number of the locking holes 313 exceeds the number of the spring pieces 33, the spring piece 33 can be locked into the locking holes 313 by simply rotating the top buckle 32 at a small angle.

[0050] Alternatively, if Fig. 9 As shown, the number of the locking holes 313 is multiple, and the number of the spring pieces 33 is also multiple. For example, the number of the locking holes 313 is two, and the two locking holes 313 are symmetrically arranged on the quick-release support tube 31. Correspondingly, the number of the spring pieces 33 is two, and the two spring pieces 33 are respectively arranged on both sides of the top buckle 32. By arranging the spring pieces 33 in the locking holes 313, the connection between the top buckle 32 and the quick-release support tube 31 is achieved. When the number of the locking holes 313 and the number of the spring pieces 33 are both multiple, the purpose of the spring pieces 33 entering the locking holes 313 and engaging can be achieved by rotating the top buckle 32 at a small angle. At the same time, the stability of the connection between the top buckle 32 and the quick-release support tube 31 can also be increased.

[0051] Alternatively, if Figure 2 As shown, the picking structure also includes at least two cover plates 4, which are respectively arranged at the two ends of the picking beam 1. For example, the cover plates 4 are installed at the two ends of the picking beam 1 with bolts, and the two ends of the groove 12 of the fixing plate 11 are sealed by the cover plates 4.

[0052] The utility model also discloses a baler, which is not shown in the figures. The baler comprises a picking structure as described in any one of the above embodiments.

[0053] Application scenario of an exemplary embodiment:

[0054] like Figures 1 to 10 As shown, first assemble the quick release assembly 3. When the spring tooth 24 of the spring tooth member 21 is damaged and needs to be replaced, only a screwdriver needs to be inserted into the quick release support tube 31, and the head end of the screwdriver contacts the bottom of the pressing groove 322 of the pressing cap 321. By pressing the screwdriver downward, the top buckle 32 is driven to move downward, and the top buckle 32 squeezes the top support spring 34 for compression. At the same time, as the top buckle 32 moves downward, the spring piece 33 undergoes elastic deformation, and the end of the spring piece 33 close to the pressing cap 321 approaches the top buckle 32, and the angle becomes smaller or disappears. At this time, the spring piece 33 is in the barrel cavity of the quick release support tube 31. After that, the entire quick release assembly 3 can be removed by only passing through the limiting edge 311 of the quick release support tube 31. The damaged spring tooth member 21 can be directly removed and replaced with a new and matching spring tooth member 21.

[0055] Place the new elastic toothed member 21 in the groove 12, and align the notch 23 of the elastic toothed member 21 with the fixing hole 15 of the fixing plate 11, and insert the quick-release support tube 31 through the notch 23 of the elastic toothed member 21, and allow the quick-release support tube 31 to enter the fixing hole 15. At this time, the limiting edge 311 of the quick-release support tube 31 presses down the elastic toothed member 21. Then insert a screwdriver into the quick-release support tube 31, and the head end of the screwdriver contacts the bottom of the pressing groove 322 of the pressing cap 321. By pressing the screwdriver downward, the top buckle 32 is driven to move downward, and the top buckle 32 squeezes the top support spring 34 for compression. At the same time, as the top buckle 32 moves downward, the spring piece 33 undergoes elastic deformation, and the end of the spring piece 33 close to the pressing cap 321 approaches the top buckle 32, and the angle becomes smaller or disappears. At this time, the spring piece 33 is in the barrel cavity of the quick-release support tube 31.

[0056] Keep the quick release support tube 31 still, remove the screwdriver, the top support spring 34 resets and drives the top buckle 32 to move upward, and the spring piece 33 returns to its original state. The end of the spring piece 33 away from the top buckle 32 extends from the clamping hole 313 of the quick release support tube 31 and contacts the lower surface of the fixed plate 11. At this time, the spring tooth member 21 and the fixed plate 11 are located between the spring piece 33 and the limiting edge 311, and the spring tooth member 21 and the fixed plate 11 are squeezed and fixed by the cooperation of the spring piece 33 and the limiting edge 311. This method of replacing the spring tooth member 21 is faster than the existing method of replacing the integrally assembled spring tooth 24.
