Description

Technical Field

[0001] This application relates to the technical field of vegetation pruning, and particularly to a pruning device for horticultural processing. Background Art

[0002] Garden vegetation pruning is a crucial task in garden maintenance management. On the one hand, it is to maintain the beautiful shape of plants. By removing excess branches, leaves, etc., the plants can maintain a good appearance and enhance their ornamental value. For example, pruning street trees into neat crown shapes can make the landscapes on both sides of the road cleaner and more beautiful; for flower shrubs, pruning can control their flowering time and flower quantity, enabling them to bloom beautiful flowers in specific seasons and adding color and atmosphere to the garden. On the other hand, pruning is also to promote the healthy growth of plants. Reasonably pruning dead branches, diseased branches, weak branches, etc. can reduce the occurrence of plant diseases and pests, improve the ventilation and light transmission conditions of the plants, make the photosynthesis of the plants more sufficient, thereby enhancing the growth potential of the plants and improving their stress resistance.

[0003] When a garden pruning device is pruning vegetation, if the vegetation has not been pruned for a long time and its branches and leaves grow lush, and if it is pruned quantitatively at this time, it may cause excessive pruning, which may result in a large number of strong photosynthetic stems and leaves being cut off, thereby causing serious nutrient loss, possibly weakening the growth of the vegetation, leading to sparser leaves, and in severe cases, may even cause the death of the vegetation. Secondly, if the pruning device has not been overhauled for a long time and a blunt knife is used for pruning, it may cause a large number of torn wounds on the vegetation. When the temperature is too high, it may cause the vegetation to lose a large amount of water, resulting in the death of the vegetation, and at the same time, it is also more likely to make the vegetation vulnerable to the invasion of pathogens.

[0046] In this embodiment, the first drive motor 6 is started to drive the threaded rod 7 to rotate. The threaded rod 7 rotates to drive the movable block 9 to move. The movable block 9 moves to drive the first extension rod 10 to move, so as to drive the cutting assembly to move up and down, adapt to the heights of different vegetation, and perform pruning, thereby improving the adaptability of the pruning device.

[0047] Among them, the adjusting assembly includes a second fixing rod 15. The second fixing rod 15 is fixedly connected to the bottom of the first rotating shaft 14. An electric push rod 16 is fixedly connected to the bottom of the middle section of the second fixing rod 15. One end of the electric push rod 16 is fixedly connected to a fixed circular plate 17. The two ends of the second fixing rod 15 are respectively hinged with a first connecting rod 18. One end of each of the two first connecting rods 18 is hinged with a second connecting rod 19.

[0048] In this embodiment, the electric push rod 16 is started to drive the fixed circular plate 17 to contract. The fixed circular plate 17 contracts to drive the third connecting rod 20 to move to one side. After the third connecting rod 20 moves, it will push the first connecting rod 18 and the fourth connecting rod 21 to move. After the first connecting rod 18 and the fourth connecting rod 21 move, they will push the annular mounting plate 23 upwards, so as to perform quantitative pruning according to the growth conditions of the vegetation branches and leaves, avoid excessive pruning of the vegetation, which may cause the stems and leaves with strong photosynthesis ability to be cut off, and then cause serious nutrient loss, which may weaken the growth of the vegetation, lead to sparser leaves, and may even cause the death of the vegetation in severe cases.

[0049] Among them, the cutting assembly includes a plurality of first cutting teeth 24, and the plurality of first cutting teeth 24 are all fixedly connected to the annular mounting plate 23. At the top of one side of the annular mounting plate 23, a third driving motor 25 is fixedly connected. The output end of the third driving motor 25 is fixedly connected to a second rotating shaft 26. On the outer side of the second rotating shaft 26, a gear 33 is fixedly connected. On the outer side of the gear 33, a cutting belt 27 is meshed and connected. On the outer side of the cutting belt 27, a plurality of second cutting teeth 28 are fixedly connected.

[0050] In this embodiment, when the second cutting teeth 28 are placed inside the annular placing plate 30, the cutting parts are attached to the grinding rod 32, and both sides of the grinding rod 32 are attached to the side blades of the two second cutting teeth 28. When the trimming device has not been started for a long time and the blades are not so sharp at this time, the third driving motor 25 can be started. The third driving motor 25 drives the gear 33 to rotate, and the gear 33 drives the second cutting teeth 28 to rotate, so that the second cutting teeth 28 are ground with the grinding rod 32, thereby improving their sharpness, avoiding a large number of torn wounds on the vegetation that may occur during trimming, avoiding a large amount of water loss in the vegetation, and thus causing the death of the vegetation. At the same time, it can also prevent the vegetation from being invaded by germs.

[0051] The placing assembly includes two fixing blocks 29, and the two fixing blocks 29 are both fixedly connected to the top of the trolley 1. At the top of the two fixing blocks 29, annular placing plates 30 are fixedly connected. On both sides inside the two annular placing plates 30, triangular grinding blocks 31 are fixedly connected, and a triangular grinding block 31 is fixedly connected to the middle section inside the annular placing plate 30.

[0052] In this embodiment, by placing the cutting assembly in the placing assembly, damage is avoided. The placing assembly can provide a physical barrier for the cutting assembly to prevent it from being accidentally damaged by external collisions, frictions, etc. At the same time, it can also reduce the contact with dust, moisture, chemical substances, etc. in the external environment to a certain extent, thereby reducing the wear and corrosion of the cutting structure.

[0053] Among them, the first connecting rod 18, the second connecting rod 19, the third connecting rod 20, the fourth connecting rod 21 and the fifth connecting rod 22 are symmetrically arranged. The length of the second connecting rod 19 is shorter than the length of the fifth connecting rod 22, and the length of the first connecting rod 18 is longer than the length of the fourth connecting rod 21.

[0054] In this embodiment, due to the symmetric arrangement of the first connecting rod 18, the second connecting rod 19, the third connecting rod 20, the fourth connecting rod 21 and the fifth connecting rod 22, the annular mounting plates 23 on both sides can move synchronously, so as to trim the vegetation in the same way, ensuring the uniformity of the shapes on both sides of the vegetation, and thus improving the beauty of the garden and the vegetation.

[0055] The first cutting teeth 24 and the second cutting teeth 28 are staggered and have the same size.

[0056] In this embodiment, the first cutting teeth 24 and the second cutting teeth 28 are staggered and of equal size, and the second cutting teeth 28 can be rotated to be tangent to the first cutting teeth 24 to shear branches and leaves.

[0057] Working principle:

[0058] When it is necessary to trim the garden vegetation, according to the lush branches and leaves of different vegetation, by starting the electric push rod 16, the electric push rod 16 is started to drive the fixed circular plate 17 to shrink, and the fixed circular plate 17 shrinks and drives the third connecting rod 20 to move to one side. After the third connecting rod 20 moves, it will push the first connecting rod 18 and the fourth connecting rod 21 to move. After the first connecting rod 18 and the fourth connecting rod 21 move, the annular mounting plate 23 will be pushed upward, so that quantitative trimming can be performed according to the growth of vegetation branches and leaves, so as to avoid excessive trimming of vegetation, which may cause the stems and leaves with strong photosynthesis ability to be cut off, thereby causing serious nutrient loss, which may weaken the growth of vegetation, cause the leaves to become sparse, and even cause the death of vegetation in severe cases. After the adjustment is completed according to the growth of vegetation branches and leaves, the second drive motor 13 is started, and the second drive motor 13 is started to drive the first rotating shaft 14 to rotate. The rotation of the first rotating shaft 14 drives the second fixed rod 15 and a series of rods to rotate, and finally drives the cutting assembly to rotate, so as to trim the vegetation into shape and complete the trimming work;

[0059] At the same time, in the garden, there is a common situation that there are patches of vegetation planted on both sides of the road. In this case, the vegetation can usually only be trimmed one by one, which is time-consuming and laborious. At this time, the electric push rod 16 can be retracted to the extreme position. At this time, the annular mounting plate 23 will be in a nearly horizontal state. At this time, the cart 1 is driven through the road, and the cutting component is started to trim the vegetation on both sides of the road, which can improve the trimming efficiency. In addition, due to its arc characteristics, it can also achieve special trimming, forming a unique garden style and improving the overall look and feel of the garden.

[0060] If the pruning device has not been started for a long time, the blade is not so sharp. At this time, the cutting assembly is placed inside the annular placement plate 30, and the third drive motor 25 can be started. The third drive motor 25 starts to drive the gear 33 to rotate, and the rotation of the gear 33 drives the second cutting tooth 28 to rotate, so that the second cutting tooth 28 and the grinding rod 32 are grinded to improve their sharpness, thereby avoiding a large number of tearing wounds on the vegetation that may be caused during pruning, avoiding a large amount of water loss in the vegetation, which may lead to the death of the vegetation, and also preventing the vegetation from being invaded by pathogens.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered by the scope of the claims of the present invention.
