[0017] The present invention provides an automatic spraying machine for fruit trees through improvement, which has the following improvements and advantages compared with the prior art:

[0018] First, the lifting mechanism of the present invention drives the bottom front side of the lifting sleeve to move upward, and the lifting sleeve rotates upward on the hinge seat using the first hinge shaft and the second hinge shaft. The lifting sleeve drives the spraying assembly to rotate upward to a suitable angle. The angle of the lifting sleeve rotating upward is suitable for matching fruit trees of different heights. At the same time, the lifting mechanism also drives the hydraulic oil therein to be squeezed to the inner tail end of the telescopic sleeve. The hydraulic oil enters the telescopic sleeve and pushes the first piston to move. The first piston moves close to the inner front end of the telescopic sleeve, and the first piston drives the sleeve and the spraying assembly away from the lifting sleeve. The cylinder moves, which facilitates the movement of the spraying component to the spraying position close to the fruit tree until the first piston moves to the inner front end of the telescopic sleeve. At this time, the medicine delivery component is connected to the L-shaped water channel. The medicine delivery component works to deliver the medicine into the L-shaped water channel, and then the medicine passes through the L-shaped water channel and the sleeve into the spraying component. The spraying component sprays the parts of the fruit tree that need to be sprayed, realizing fully automated spraying of the higher and higher parts of the fruit tree. There is no need to manually complete a series of adjustment actions. The steps are simple, which is conducive to quick spraying operations on multiple fruit trees, greatly improving the spraying efficiency.

[0019] Second: In the present invention, when the telescopic rod drives the connecting ring to rotate, the connecting ring uses four arc blocks to realize rotation on the annular groove. The elastic force of the first spring ensures that the four arc blocks always slide in the annular groove. When the lifting sleeve rotates upward to a suitable angle, the hydraulic push rod drives the push plate to move close to the fixed sleeve. The push plate drives the connecting ring to move close to the fixed sleeve by using the push plate. At the same time, the push plate drives the limit frame to move close to the limit gear. The limit frame drives the limit rack to move until it engages with the limit gear. After the limit rack moves to fully engage with the limit gear, the connecting ring can drive the head end of the telescopic rod to completely separate from the slot.

[0020] Third: The control valve of the present invention controls the hydraulic oil in the first oil pipe to flow only in one direction toward the internal tail end of the telescopic sleeve, and the hydraulic oil in the second oil pipe to flow only in one direction toward the internal top end of the extrusion cylinder. The second mounting shaft drives the cam to rotate, and the cam uses the extrusion wheel to drive the extrusion plate to move back and forth on the two vertical rails. The extrusion plate uses the vertical rod to drive the second piston to move back and forth in the extrusion cylinder. When the second piston moves upward in the extrusion cylinder, the second piston squeezes the hydraulic oil in the extrusion cylinder into the first oil pipe, and the hydraulic oil enters the internal tail end of the telescopic sleeve through the first oil pipe to push the first piston to move. When the second piston moves downward in the extrusion cylinder, the second piston draws the hydraulic oil in the oil tank into the extrusion cylinder through the first oil pipe, and then the extrusion cylinder is always filled with hydraulic oil.

[0021] Fourthly: When the first hinge shaft of the present invention rotates, it drives the mounting sleeve and the mounting rod to rotate. The mounting rod drives the sliding column to slide in the arc-shaped sliding groove. The sliding column drives the identification column to move synchronously. The three identification components sense the position of the identification column. The larger the movement position of the identification column, the greater the upward rotation angle of the lifting sleeve. The identified rotation angle is then used to control the delivery power of the booster pump. The greater the upward rotation angle, the higher the delivery power of the booster pump.

[0041] The present invention is described in detail below, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0042] The present invention provides an automatic spraying machine for fruit trees through improvement. Figures 1-18As shown, the sprayer comprises a sprayer body 1, with an articulated seat 2 provided at the top middle section of the sprayer body 1. A first articulated shaft 21 and a second articulated shaft 22 are rotatably mounted on the top of the articulated seat 2. One end of the first articulated shaft 21 extends to the exterior of the articulated seat 2. A lifting sleeve 3 is mounted between the first articulated shaft 21 and the second articulated shaft 22. A telescopic sleeve 4 is horizontally disposed within the lifting sleeve 3. A first piston 41 is slidably mounted within the telescopic sleeve 4. An L-shaped water channel 42 is defined on the first piston 41. A sleeve 43 is provided on the first piston 41. The front end of the sleeve 43 extends to the exterior of the telescopic sleeve 4. A sprayer assembly 5 is connected to the front end of the sleeve 43. The rear end of the sleeve 43 is connected to the L-shaped water channel 42.

[0043] Specifically, a lifting mechanism 6 is provided on the top front side of the spraying vehicle body 1, one end of the top of the lifting mechanism 6 is in contact with the bottom front side of the lifting sleeve 3, and the other end of the top of the lifting mechanism 6 is connected with the internal tail end of the telescopic sleeve 4. A drug delivery component 7 is provided on the top rear side of the spraying vehicle body 1, and one end of the drug delivery component 7 extends to be connected with the internal front end of the telescopic sleeve 4, and an identification component 8 is provided at one end of the first hinge shaft 21 extending to the outside of the hinge seat 2.

[0044] In this embodiment, when spraying the higher and higher parts of the fruit trees, the lifting mechanism 6 drives the bottom front side of the lifting sleeve 3 to move upward, and the lifting sleeve 3 rotates upward on the hinge seat 2 using the first hinge shaft 21 and the second hinge shaft 22. The lifting sleeve 3 drives the spraying assembly 5 to rotate upward to a suitable angle. The angle of the lifting sleeve 3 rotating upward is suitable for matching the different heights of the fruit trees. At the same time, the lifting mechanism 6 also drives the hydraulic oil therein to be squeezed to the internal tail end of the telescopic sleeve 4. The hydraulic oil enters the telescopic sleeve 4 and pushes the first piston 41 to move. The first piston 41 is close to the internal front end of the telescopic sleeve 4. The end moves, the first piston 41 drives the sleeve 43 and the spraying assembly 5 to move away from the lifting sleeve 3, making it convenient for the spraying assembly 5 to move close to the fruit tree spraying location, until the first piston 41 moves to the internal front end of the telescopic sleeve 4. At this time, the medicine delivery assembly 7 is connected to the L-shaped water channel 42, and the medicine delivery assembly 7 works to transport the medicine into the L-shaped water channel 42, and then the medicine passes through the L-shaped water channel 42 and the sleeve 43 into the spraying assembly 5, and the spraying assembly 5 sprays the parts of the fruit tree that need to be sprayed. The identification assembly 8 is used to sense the rotation angle of the first hinge shaft 21 to identify the upward rotation angle of the lifting sleeve 3.

[0045] Furthermore, the identified rotation angle is used to control the delivery power of the medicine delivery component 7. The greater the upward rotation angle, the higher the delivery power of the medicine delivery component 7, ensuring that the medicine can quickly enter the spraying component 5 located at a higher position. After the above steps, fully automated spraying of higher and higher parts of the fruit trees is achieved without the need to manually complete a series of adjustment actions. The steps are simple, which is conducive to quick spraying operations on multiple fruit trees, greatly improving the spraying efficiency.

[0046] In some embodiments, the lifting mechanism 6 includes a lifting sleeve 61, a lifting column 611, a lifting seat 612, a lifting plate 613, a lifting rack 614, a lifting shaft 615, a lifting gear 616, a first mounting seat 617, a second mounting seat 618, a driving wheel 62, a driven wheel 63, a belt 64, a cam 65, a drive motor 66, an extrusion assembly 67, a linkage switching assembly 68 and two support plates 69.

[0047] Specifically, the lifting sleeve 61 is vertically arranged on the top front side of the spraying vehicle body 1. The top outer wall of the lifting sleeve 61 is provided with a through slot communicating with the interior thereof. The lifting column 611 is slidably installed in the lifting sleeve 61, and the top of the lifting column 611 extends above the lifting sleeve 61. The lifting seat 612 is installed on the top of the lifting column 611. The lifting plate 613 is hinged to the top of the lifting seat 612, and the top of the lifting plate 613 abuts against the bottom of the lifting sleeve 3. The lifting rack 614 is vertically arranged on the outer wall of the lifting column 611. Two support plates 69 are symmetrically arranged on the top outer wall of the lifting sleeve 61. A lifting shaft 615 is rotatably mounted on the two support plates 69, and one end of the lifting shaft 615 extends to the outside of one of the support plates 69. A lifting gear 616 is installed on the lifting shaft 615, and one side of the lifting gear 616 passes through the through slot and meshes with the lifting rack 614.

[0048] Furthermore, the first mounting seat 617 and the second mounting seat 618 are spaced apart on the top of the spray vehicle body 1, and a first mounting shaft 6171 is rotatably mounted in the first mounting seat 617, and one end of the first mounting shaft 6171 extends to the outside of the first mounting seat 617, and a second mounting shaft 6181 is rotatably mounted in the second mounting seat 618, and one end of the second mounting shaft 6181 close to the first mounting shaft 6171 extends to the outside of the second mounting seat 618, the driving wheel 62 is mounted on the first mounting shaft 6171, the driven wheel 63 is mounted on the end of the lifting shaft 615, the belt 64 is sleeved on the outside of the driving wheel 62 and the driven wheel 63, the cam 65 is mounted on the second mounting shaft 6181, the drive motor 66 is mounted on the outer wall of the second mounting seat 618, and the output shaft of the drive motor 66 is connected to the second mounting shaft 6181.

[0049] The extrusion assembly 67 is installed on the top of the sprayer body 1, and one end of the extrusion assembly 67 is in contact with the top of the cam 65, and the other end of the extrusion assembly 67 is connected to the inner tail end of the telescopic sleeve 4. The linkage switching assembly 68 is installed on the top of the sprayer body 1, and the two ends of the linkage switching assembly 68 are respectively connected to the first mounting shaft 6171 and the second mounting shaft 6181.

[0050] In this embodiment, the second mounting shaft 6181 and the cam 65 are driven to rotate by the driving motor 66, and the cam 65 drives the extrusion assembly 67 to work. The extrusion assembly 67 squeezes the hydraulic oil therein to the inner tail end of the telescopic sleeve 4, so that the first piston 41 can push the spraying assembly 5 to move close to the fruit tree spraying position. At the same time, the second mounting shaft 6181 drives the first mounting shaft 6171 and the driving wheel 62 to rotate by the linkage switching assembly 68, and the driving wheel 62 drives the driven wheel 63 and the lifting shaft 615 to rotate by the belt 64. The lifting shaft 615 drives the lifting rack 614 to move upward by the lifting gear 616, and the lifting rack 614 drives the lifting column 611 to move upward, and the lifting column 611 drives the lifting sleeve by the lifting plate 613 3 moves upward, and the lifting sleeve 3 rotates upward on the hinge seat 2 using the first hinge shaft 21 and the second hinge shaft 22. The lifting sleeve 3 drives the spray assembly 5 to rotate upward to a suitable angle. When the lifting sleeve 3 rotates upward to a suitable angle, the linkage switching assembly 68 works to cancel the connection with the first installation shaft 6171. At the same time, the linkage switching assembly 68 jams the first installation shaft 6171 to prevent the lifting column 611 from unnecessary lifting. At this time, the drive motor 66 continues to work and uses the cam 65 and the extrusion assembly 67 to drive the first piston 41 to move to the inner front end of the telescopic sleeve 4, so that the medicine delivery assembly 7 is connected to the L-shaped water channel 42. The medicine delivery assembly 7 works to deliver the medicine into the L-shaped water channel 42.

[0051] In some embodiments, the linkage switching assembly 68 includes a fixed plate 681, a fixed sleeve 682, a connecting plate 683, a telescopic rod 684, an insertion rod 685, a first spring 686, a limiting gear 687 and a switching component 688.

The connecting plate 683 is installed inside the fixed sleeve 682, and the telescopic rod 684 is slidably installed in the fixed sleeve 682, and the head end of the telescopic rod 684 extends to the outside of the fixed sleeve 682. Four first ridges 6841 are provided on the outer wall of the telescopic rod 684, and the four first ridges 6841 correspond one-to-one to the four first linkage grooves 6821.

[0052] The first spring 686 is installed on the connecting plate 683, and the end of the first spring 686 away from the connecting plate 683 is connected to the tail end of the telescopic rod 684, the insertion rod 685 is installed on the head end of the telescopic rod 684, and four second ridges 6851 are arranged at equal intervals on the outer wall of the insertion rod 685. The end of the first mounting shaft 6171 is provided with a slot 6172 for the insertion of the insertion rod 685, and four second linkage grooves 6173 are provided in the slot 6172. The four second linkage grooves 6173 correspond one-to-one to the four second ridges 6851. The head end of the insertion rod 685 is inserted into the slot 6172, and the limiting gear 687 is installed on the first mounting shaft 6171. The switching component 688 is installed on the top of the sprayer vehicle body 1, and one end of the switching component 688 extends to connect with the head end of the telescopic rod 684.

[0053] In this embodiment, the second mounting shaft 6181 drives the fixed plate 681 and the fixed sleeve 682 to rotate, and the fixed sleeve 682 uses the four first linkage grooves 6821 and the four first ridges 6841 to drive the telescopic rod 684 to rotate, and the telescopic rod 684 uses the four second ridges 6851 and the four second linkage grooves 6173 to drive the first mounting shaft 6171 to rotate. When the lifting sleeve 3 is rotated upward to a suitable angle, the switching component 688 drives the part connected to the head end of the telescopic rod 684 to move close to the fixed sleeve 682. At this time, the head end of the telescopic rod 684 moves to separate from the slot 6172, and the switching component 688 also drives one end of it to move to be locked with the limit gear 687, thereby achieving the locking of the first mounting shaft 6171. At the same time, the first spring 686 is compressed and deformed between the connecting plate 683 and the tail end of the telescopic rod 684.

[0054] In some embodiments, the switching component 688 includes a supporting plate 6881 , a cross rail 6882 , a push plate 6883 , a U-shaped frame 6884 , a hydraulic push rod 6885 , a limiting member 6886 , a pushing plate 6887 , an annular groove 6888 and a connecting ring 6889 .

[0055] The load-bearing plate 6881 is installed on the top of the spray vehicle body 1, the cross rail 6882 is horizontally arranged on the top outer wall of the load-bearing plate 6881, the push plate 6883 is slidably installed on the cross rail 6882, the U-shaped frame 6884 is installed on the top of the spray vehicle body 1, the hydraulic push rod 6885 is horizontally arranged on the top of the U-shaped frame 6884, the output end of the hydraulic push rod 6885 is connected to the push plate 6883, and the limit member 6886 is installed on the outer wall of the push plate 6883 near the limit gear 687.

[0056] The pushing plate 6887 is installed at the end of the pushing plate 6883 away from the cross rail 6882, the annular groove 6888 is opened on the outer wall of the pushing plate 6887, the connecting ring 6889 is installed on the outer wall of the head end of the telescopic rod 684, and four equally spaced arc blocks 9 are provided on the side of the connecting ring 6889 close to the pushing plate 6887. The four arc blocks 9 slide in cooperation with the annular groove 6888.

[0057] In this embodiment, when the telescopic rod 684 drives the connecting ring 6889 to rotate, the connecting ring 6889 uses the four arc blocks 9 to rotate on the annular groove 6888. The elastic force of the first spring 686 ensures that the four arc blocks 9 always slide in the annular groove 6888. When the lifting sleeve 3 rotates upward to a suitable angle, the hydraulic push rod 6885 works to drive the push plate 6883 to move close to the fixed sleeve 682. The push plate 6883 uses the push disk 6887 to drive the connecting ring 6889 to move close to the fixed sleeve 682.
