Description

Technical Field

[0001] The utility model relates to the technical field of mulberry tree cutting equipment, in particular to a mulberry tree cutting device and a mulberry tree cutter. Background Art

[0002] Mulberry silkworm breeding is an important agricultural economic model in the mountainous areas of southern China at present, and the main raw material for mulberry silkworm breeding comes from the planting of mulberry leaves. Although mulberry trees are perennial arbors or shrubs, in order to improve the product of mulberry leaves, the mulberry trees planted by current farmers generally need to be cut down every year so that new branches can grow out in the coming year. This can not only control the height of the mulberry trees, which is beneficial to picking mulberry leaves, but also re-promote the branches to increase the yield of mulberry leaves. The cutting work of traditional mulberry trees is basically carried out by manually holding a machete to cut each tree one by one, with a large overall labor intensity and low work efficiency.

[0003] In view of the above situation, the patent with the publication number CN105284440B discloses a mulberry tree cutting and branch discharging integrated device, which can realize the integration of cutting and discharging branches, thus overcoming the disadvantages of low efficiency and large labor intensity of the existing manual cutting of mulberry trees. However, the cutting mechanism in this patent adopts the form of a single saw disc, and at the same time, it cooperates with the branch discharging mechanism to discharge the fallen mulberry branches to one side. Such a structure causes that when the single saw disc cuts the mulberry branches, since the mulberry branches have no other structure to straighten or support them, when receiving the unilateral cutting force of the single saw disc, they are prone to uneven stress and random lodging and swinging, which in turn leads to uneven heights of the cutting edges of the cut branches, directly affecting the cutting work of the mulberry branches and the subsequent branch promoting work.

[0029] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further describes the present utility model in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0030] Refer to Figures 1 to 4A mulberry tree cutter as shown includes a self - propelled device 50 and a mulberry tree cutting device. The self - propelled device 50 can be of the structure of a traditional walking diesel tractor, which is adapted for agricultural use. The specific structure is not described in detail in this application. For reference, the tractor structure in the mulberry tree cutting and branch discharging integrated device disclosed in the patent with the publication number CN105284440B can be referred to. Among them, the mulberry tree cutting device includes a pressure bar frame 10, a lifting frame 20, a mulberry tree cutting mechanism 30 and a transmission mechanism 40. The pressure bar frame 10 is used to tilt and lay down the mulberry tree; the lifting frame 20 is installed on the pressure bar frame 10 in a liftable manner; the mulberry tree cutting mechanism 30 is installed on the lifting frame 20, and the mulberry tree cutting mechanism 30 includes a pair of rotatable and cooperating saw disks 31; the transmission mechanism 40 is installed in the lifting frame 20, and the output end of the transmission mechanism 40 can drive the two saw disks 31 to rotate synchronously at the same time.

[0031] Among them, the pressure bar frame 10 is installed on the front end of the tractor 50, and the mulberry tree cutting mechanism 30 is arranged on one side in the advancing direction of the pressure bar frame 10. In this application, the input of the transmission mechanism 40 is connected to the flywheel of the tractor 50 through a belt, so as to drive the two saw disks 31 to rotate synchronously.

[0032] This mulberry tree cutting device and the mulberry tree cutter use the pressure bar frame 10 to tilt and lay down the mulberry tree, making the root of the mulberry tree bend, which is beneficial for the pair of saw disks 31 to cut; the setting of the lifting frame 20 is beneficial for adjusting the height of the saw disks 31 to adapt to the requirements of different cutting heights. And two saw disks 31 are provided and cooperate with each other, so that the mulberry tree is stressed on both sides at the same time during the cutting process, improving the stability of the laid - down mulberry tree and being beneficial for the subsequent collection of mulberry branches. And the output end of the transmission mechanism 40 can drive the two saw disks 31 to rotate synchronously at the same time. Such a design makes the acting forces of the two saw disks 31 on the mulberry branches the same, which is beneficial for ensuring the stability of the mulberry branches during the cutting process.

[0033] Further refer to Figures 1 to 3 In this application, the pressure bar frame 10 includes a cross beam 11, vertical beams 12 arranged at both ends of the cross beam 11, and support rods 13 arranged at the bottom of the vertical beams 12. The same ends of the two support rods 13 are connected through a U - shaped frame 14, and the U - shaped frame 14 tilts upwards. The two ends of the lifting frame 20 are respectively slidably installed on the two vertical beams 12. Among them, an installation frame is arranged on the back of the cross beam 11, and the installation frame is installed on the front end frame of the tractor. And the U - shaped frame 14 is arranged on one side in the advancing direction of the cross beam 11. The main purpose of such a setting is that when the tractor drives the whole mulberry tree cutting device forward, the U - shaped frame 14 can pre - limit the upright mulberry branches and bend them, which is beneficial for the two saw disks 31 to cut together or separately.

[0034] Among them, in order to facilitate the up-and-down movement of the lifting frame 20, chutes 15 are provided on both of the vertical beams 12, and both ends of the lifting frame 20 are slidably installed in the chutes 15 of the corresponding vertical beam 12 on one side.

[0035] In addition, in one embodiment, in order to reduce the wear of the mulberry branches on the U-shaped frame 14, a protective cylinder is sleeved on the U-shaped frame 14.

[0036] In addition, in the above embodiment, in order to improve the straightening and restricting ability of the mulberry branches, the U-shaped frame 14 can be changed to a V-shaped frame, which can make the two upright mulberry branches on both sides automatically move closer to the middle, which is beneficial to cutting and improves the regularity of the mulberry branches after cutting in the later stage.

[0037] See Figures 2 to 4 , in order to better realize the synchronous rotation of the two saw disks 31, and the flywheel of the tractor is horizontally arranged. Therefore, in order to achieve better transmission, in one embodiment of the present application, the transmission mechanism 40 includes an input shaft 41, a transmission shaft 42 and an output shaft 43. The input shaft 41 and the output shaft 43 are arranged in parallel, and the input shaft 41 and the output shaft 43 are both perpendicular to the transmission shaft 42. Between the input shaft 41 and the transmission shaft 42, and between the transmission shaft 42 and the output shaft 43 are both connected by a steering gear 44. There are two output shafts 43, and each output shaft 43 is connected to the rotation center of the saw disk 31 through a steering gear 44. Among them, the input shaft 41 and the output shaft 43 are both horizontally arranged, mainly to adapt to the rotation center of the flywheel of the tractor, so that the output shaft 43 can be directly connected to the flywheel through a belt, which is beneficial to direct drive connection. And the rotation center of the saw disk 31 is in the vertical direction, so a steering gear 44 is needed for steering transmission. In the present application, the steering gear 44 is actually a structure containing bevel gear transmission inside, which can realize vertical steering transmission. In addition, the hidden bevel gear transmission method inside the steering gear 44 can effectively protect the meshing condition of the internal gears and improve the protection performance. Of course, in some embodiments, the input shaft 41 and the output shaft 43 can be directly connected by a belt.

[0038] In the above embodiment, the input shaft 41, the transmission shaft 42 and the output shaft 43 all need to be fixed. Therefore, the input shaft 41, the transmission shaft 42 and the output shaft 43 are all installed on the lifting frame 20 through rotating bearings, or the steering gear 44 is directly fixed on the lifting frame 20, so as to use the steering gear 44 body to realize support and fixation.

[0039] Certainly, in an embodiment of the present application, in order to achieve the intensification of the structure and improve the overall strength at the same time, the transmission mechanism 40 is completely hidden inside in the present application. Among them, the lifting frame 20 includes a main body cylinder 21, a vertical cylinder 22 and a horizontal cylinder 23. The main body cylinder 21 and the horizontal cylinder 23 are arranged in parallel, and the main body cylinder 21 and the horizontal cylinder 23 are both perpendicular to the vertical cylinder 22. One end of the horizontal cylinder 23 and one end of the vertical cylinder 22 are both installed on the housing of the corresponding steering gear 44, and the middle of the main body cylinder 21 and the other end of the vertical cylinder 22 are both installed on the housing of the corresponding steering gear 44; the transmission shaft 42 is rotatably installed in the vertical cylinder 22, the input shaft 41 is rotatably installed in the horizontal cylinder 23, and the two output shafts 43 are both rotatably installed in the main body cylinder 21. Both ends of the main body cylinder 21 can be slidably installed on the pressure rod frame 10 and can be relatively locked. In fact, in this embodiment, the lifting frame 20 and the transmission mechanism 40 are combined and configured, and its main purpose is to improve the strength of the entire transmission mechanism 40, which is beneficial to transmitting large-torque power. In fact, such a setting can also make the lifting frame 20 and the transmission mechanism 40 lift synchronously, adapting to the height adjustment of the two saw disks 31.

[0040] In the above embodiment, in order to better adjust the height of the entire lifting frame 20, sliding seats 24 are provided at both ends of the main body cylinder 21. The sliding seats 24 can be slidably installed on the pressure rod frame 10 and can be relatively locked. Among them, the sliding seats 24 are slidably installed in the sliding grooves 15 and are locked by bolts.

[0041] See Figures 2 to 4 , in an embodiment of the present application, the mulberry cutting mechanism 30 includes a flange 32 and a drive shaft 33. The flange 32 is installed on the drive shaft 33. The drive shaft 33 is connected to the output end of the corresponding steering gear 44. The saw disk 31 is installed on the flange 32. Such a setting can facilitate the replacement of the saw disk 31. Further, the two saw disks 31 are arranged in a vertical and staggered manner. Such a setting makes it certain that the cooperation of the two saw disks 31 can cut the mulberry branches.
