Description

Technical Field

[0001] The invention relates to the technical field of orchard machines, and in particular to a hydraulic lifting auxiliary device for an orchard machine. Background Art

[0002] An orchard refers to a garden where fruit trees are planted, also called a fruit garden. In the process of taking care of the orchard, it is necessary to turn the soil, apply fertilizers, water and irrigate, and pick the fruits, so different orchard machines will be used.

[0003] When using an existing orchard machine, the agricultural machinery to be used is usually installed on the orchard machine, and then the agricultural machinery is lifted or lowered for use by a hydraulic device. However, the existing hydraulic device is usually arranged in the gearbox of the orchard machine, which is very inconvenient to maintain and repair. In addition, the hydraulic device lacks a limit device. Excessive extension of the hydraulic cylinder may cause damage to the orchard machine frame, and excessive lowering may cause damage to the agricultural machinery. If the hydraulic cylinder fails and loses its supporting force, the agricultural machinery will fall rapidly and be damaged. Moreover, when the orchard machine is working, the agricultural machinery needs to be lifted and lowered frequently, so the hydraulic cylinder will extend and retract at a high frequency. The high-load extension and retraction of the hydraulic cylinder will generate a large amount of heat inside it due to friction, and overheating will make the hydraulic cylinder prone to failure and damage.

[0016] Preferably, the mounting seat is fixedly connected to the orchard machine body by a plurality of bolts.

[0017] The present invention has the following beneficial effects:

[0018] 1. By setting a limit mechanism, when the first slider slides to the most side end of the slide slot, the first slider cannot continue to slide, and the lifting seat cannot continue to move upward. At this time, it cannot continue to lift, and the extension length of the hydraulic cylinder is limited to prevent the hydraulic cylinder from being over-extended, causing the agricultural implement to be lifted too high, which may cause damage to the frame of the orchard machine;

[0019] 2. When the conductive plate contacts the conductive block, the alarm will sound to give a warning. At this time, the staff can clearly know that the maximum lifting height has been reached and immediately stop the extension of the hydraulic cylinder to prevent the hydraulic cylinder from over-extending and causing damage to the agricultural machinery;

[0020] 3. When the hydraulic cylinder suddenly fails and loses its supporting force, the lifting seat will drop rapidly, which will drive the two connecting rods to rotate rapidly towards each other, drive the two cross bars to move towards each other, and drive the two sliding plugs to move rapidly towards each other. At this time, the two sliding plugs will give the non-Newtonian fluid in the storage chamber a greater instantaneous pressure, and the non-Newtonian fluid will harden rapidly, making it impossible for the sliding plugs to slide towards each other, preventing the lifting seat from falling rapidly, thereby preventing the sudden failure of the hydraulic cylinder from causing the agricultural machinery to fall and be damaged;

[0021] 4. By setting up an auxiliary lifting mechanism, during the process of lifting the lifting seat upward, the two connecting rods will rotate away from each other, and the two first sliding blocks will slide away from each other. In the process of the connecting rods moving away from each other, the two cross bars will be driven to move, and then the two sliding plugs will be driven to slide away from each other. At this time, the air in the pump air cavity will be squeezed into the slide cylinder through the connecting pipe. The pressure in the slide cylinder increases, which will push the slide plate to slide upward, and then drive the first auxiliary rod to move upward, giving the lifting seat an upward force, thereby sharing the pressure of the hydraulic cylinder, assisting in lifting, and reducing the load of the hydraulic cylinder;

[0022] 5. By setting the lead screw, the second slider and the second auxiliary rod, when lifting, the sliding of the first slider will drive the rifle rod to move, and then drive the third bevel gear to rotate, drive the fourth bevel gear to rotate, and drive the lead screw to rotate. At this time, the second slider will slide upward, drive the second auxiliary rod to slide upward, give the lifting seat an upward force, and further share the pressure of the hydraulic cylinder, enhancing the auxiliary lifting effect;

[0023] 6. By setting up a heat dissipation mechanism and a driving mechanism, when lifting, the sliding of the first slider will drive the rifle rod to move, and then drive the third bevel gear to rotate, drive the fourth bevel gear to rotate, drive the lead screw to rotate, the lead screw rotation will drive the first bevel gear to rotate, drive the second bevel gear to rotate, drive the reciprocating lead screw to rotate, drive the moving block to slide back and forth on the inner wall of the pump water tank, and the moving block will drive the rectangular block to slide back and forth through the push rod. Under the action of the rectangular block, the external water will be drawn into the pump water tank through the one-way water inlet pipe, and then the water in the pump water tank will enter the sprinkler head through the one-way water supply pipe, and finally the water will be sprayed out through the sprinkler head to cool down the hydraulic cylinder, so as to avoid the hydraulic cylinder from being damaged by excessive temperature due to the friction caused by repeated expansion and contraction;

[0024] 7. The rotation of the reciprocating screw will synchronously drive the rotation of the shaft, drive multiple fan blades to rotate, blow air to dissipate heat from the hydraulic cylinder, and further improve the cooling effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific implementation disclosed below.

[0035] Reference Figure 1 - Figure 8 A hydraulic lifting auxiliary device for an orchard machine comprises a mounting seat 1, the mounting seat 1 is fixedly connected to the orchard machine body by a plurality of bolts, the upper end of the mounting seat 1 is fixedly connected to four guide rods 2, the side walls of the four guide rods 2 are slidably connected to a lifting seat 3, the upper end of the lifting seat 3 is fixedly connected to a plurality of mounting frames 4, the upper end of the mounting seat 1 is fixedly connected to a hydraulic cylinder 5, and the movable end of the hydraulic cylinder 5 is fixedly connected to the lower end of the lifting seat 3;

[0036] Furthermore, the mounting seat 1 is fixed to the orchard machine body with bolts, and then the agricultural machinery is fixedly mounted on the mounting frame 4 with bolts, and then the hydraulic cylinder 5 is driven to extend, driving the lifting seat 3 to rise, and then driving the agricultural machinery installed on the mounting frame 4 to lift. Since the overall lifting device is installed on the orchard machine body, it is convenient to carry out maintenance and repair.

[0037] The limiting mechanism includes a mounting plate 6 fixedly connected to the upper ends of the four guide rods 2, and two sliding grooves 61 are symmetrically provided at the lower end of the mounting plate 6. Two first sliders 7 are symmetrically slidably connected to the inner walls of the two sliding grooves 61, and a sliding rod 71 is fixedly connected to the inner wall of the sliding groove 61. The side wall of the sliding rod 71 is slidably connected to the first slider 7, and the lower ends of the two first sliders 7 are symmetrically rotatably connected to two connecting rods 8. The lower ends of the two connecting rods 8 are both rotatably connected to the upper end of the lifting seat 3. The lower end of the mounting plate 6 is fixedly connected to a box body 9 through a fixed shaft, and two sliding plugs 10 are symmetrically sealed and slidably connected to the inner wall of the box body 9. The two sliding plugs 10 divide the box body 9 into three parts: two pump air chambers 101 and a storage chamber 102. The storage chamber 102 is filled with non-Newtonian fluid, and the side walls of the two sliding plugs 10 are fixedly connected to a cross bar 91, and one end of the cross bar 91 passes through the side wall of the box body 9 and is rotatably connected to the connecting rod 8.

[0038] Furthermore, when the first slider 7 slides to the sidemost end of the slide groove 61, the first slider 7 cannot continue to slide, and the lifting seat 3 cannot continue to move upward. At this time, it is impossible to continue lifting, and the extension length of the hydraulic cylinder 5 is limited to prevent the hydraulic cylinder 5 from being over-extended, causing the agricultural machinery to be lifted too high, which may cause damage to the frame of the orchard machine.

[0039] It is worth mentioning that when the hydraulic cylinder 5 suddenly fails and loses its supporting force, the lifting seat 3 will drop rapidly, thereby driving the two connecting rods 8 to rotate rapidly towards each other, driving the two cross bars 91 to move towards each other, and driving the two sliding plugs 10 to move rapidly towards each other. At this time, the two sliding plugs 10 will give the non-Newtonian fluid in the storage chamber 102 a momentary large pressure, and the non-Newtonian fluid will harden rapidly, thereby preventing the sliding plugs 10 from sliding towards each other, preventing the lifting seat 3 from falling rapidly, thereby preventing the sudden failure of the hydraulic cylinder 5 from causing the agricultural machinery to fall and be damaged.

[0040] The limiting mechanism also includes a conductive plate 11 fixedly connected to the side wall of the first slider 7, a conductive block 12 fixedly connected to the inner wall of the slide groove 61, an alarm 13 fixedly connected to the upper end of the mounting plate 6, and the conductive plate 11, the conductive block 12, the alarm 13 and the external power supply are electrically connected through wires.

[0041] Furthermore, when the conductive plate 11 contacts the conductive block 12, the alarm 13 will sound to give a sound prompt. At this time, the staff can clearly know that the lifting has reached the maximum height and immediately stop the extension of the hydraulic cylinder 5 to prevent the hydraulic cylinder 5 from over-extending and causing damage to the agricultural machinery.

[0042] The side walls of the two guide rods 2 located on the same side are commonly fixedly connected with a transverse plate 14, and an auxiliary lifting mechanism is installed on the transverse plate 14. The auxiliary lifting mechanism includes a slide tube 15 fixedly connected to the side wall of the transverse plate 14 through a fixed shaft, and a slide plate 16 is sealingly and slidably connected to the inner wall of the slide tube 15. The upper end of the slide plate 16 is fixedly connected to a first auxiliary rod 17, and the upper end of the first auxiliary rod 17 passes through the upper end of the slide tube 15 and is fixedly connected to the lifting seat 3. The pump air chamber 101 is connected with the slide tube 15 through a connecting pipe 18, and the connecting pipe 18 is made of a hose.

[0043] Furthermore, during the process of the lifting seat 3 being lifted upward, the two connecting rods 8 will rotate away from each other, and the two first sliding blocks 7 will slide away from each other. In the process of the connecting rods 8 moving away from each other, the two cross bars 91 will be driven to move, thereby driving the two sliding plugs 10 to slide away from each other in a sealed manner. At this time, the air in the pump air chamber 101 will be squeezed into the slide cylinder 15 through the connecting pipe 18. The pressure in the slide cylinder 15 increases, which will push the slide plate 16 to slide upward, thereby driving the first auxiliary rod 17 to move upward, giving the lifting seat 3 an upward force, thereby sharing the pressure of the hydraulic cylinder 5, assisting in lifting, and reducing the load of the hydraulic cylinder 5.

[0044] A heat dissipation mechanism is installed on the lifting seat 3, and the heat dissipation mechanism includes two water spray heads 19 symmetrically fixedly connected to the lower end of the lifting seat 3. Two pump water tanks 20 are symmetrically fixedly connected to the upper end of the mounting seat 1. The inner walls of the two pump water tanks 20 are sealed and slidably connected with rectangular blocks 21. A one-way water inlet pipe 22 is fixedly connected to the side wall of the pump water tank 20. The other end of the one-way water inlet pipe 22 is connected to the water storage tank on the orchard machine. The pump water tank 20 is connected to the water spray head 19 through a one-way water supply pipe 23. The one-way water inlet pipe 22 only allows external water to enter the pump water tank 20, and the one-way water supply pipe 23 only allows water in the pump water tank 20 to enter the water spray head 19.

[0045] The heat dissipation mechanism also includes a moving block 24 slidably connected to the inner wall of the pump water tank 20. The moving block 24 is symmetrically fixedly connected to the side wall of the rectangular block 21 with two push rods 25. The other ends of the two push rods 25 are fixedly connected to the rectangular block 21. A reciprocating screw 26 is rotatably connected to the inner wall of the pump water tank 20. The side wall of the reciprocating screw 26 is threadedly connected to the moving block 24. One end of the reciprocating screw 26 is coaxially fixedly connected to a rotating shaft 27. One end of the rotating shaft 27 passes through the rectangular block 21 and the side wall of the pump water tank 20 and is fixedly connected to a plurality of fan blades 28.

[0046] A driving mechanism is installed on the mounting base 1, and the driving mechanism includes two lead screws 29 symmetrically connected to the upper end of the mounting base 1, a first bevel gear 30 is fixedly connected to the side wall of the lead screw 29, one end of the reciprocating lead screw 26 passes through the side wall of the pump water tank 20 and is fixedly connected to the second bevel gear 31, and the first bevel gear 30 is meshed with the second bevel gear 31.

[0047] The driving mechanism also includes a rifle rod 32 fixedly connected to the side wall of the first slider 7, one end of the rifle rod 32 penetrates the side wall of the mounting plate 6, the side wall of the rifle rod 32 is threadedly connected with a third bevel gear 33, the upper end of the lead screw 29 is fixedly connected with a fourth bevel gear 34, the third bevel gear 33 is meshed with the fourth bevel gear 34, the side wall of the mounting plate 6 is symmetrically fixedly connected with two annular plates 35 through a fixed axis, the side wall of the annular plate 35 is provided with an annular groove 36, the inner wall of the annular groove 36 is symmetrically slidably connected with two limit rods 37, one end of the two limit rods 37 are fixedly connected to the side wall of the third bevel gear 33, the upper end of the lifting seat 3 is symmetrically provided with two circular holes 38, and the two lead screws 29 are respectively provided through the two circular holes 38.

[0048] It should be noted that the cross-section of the annular groove 36 is T-shaped, and the limiting rod 37 is T-shaped. The limiting rod 37 cooperates with the annular groove 36 to limit the third bevel gear 33 to prevent the third bevel gear 33 from moving horizontally with the rifle rod 32.

[0049] Furthermore, during lifting, the sliding of the first slider 7 will drive the rifle rod 32 to move, and then drive the third bevel gear 33 to rotate, drive the fourth bevel gear 34 to rotate, and drive the lead screw 29 to rotate. The rotation of the lead screw 29 will drive the first bevel gear 30 to rotate, drive the second bevel gear 31 to rotate, drive the reciprocating lead screw 26 to rotate, and drive the moving block 24 to slide back and forth on the inner wall of the pump water box 20. The moving block 24 will drive the rectangular block 21 to slide back and forth in a sealed manner through the push rod 25. Under the action of the rectangular block 21, external water will be drawn into the pump water box 20 through the one-way water inlet pipe 22, and then the water in the pump water box 20 will enter the sprinkler head 19 through the one-way water supply pipe 23. Finally, the water is sprayed out through the sprinkler head 19 to cool down the hydraulic cylinder 5 and prevent the hydraulic cylinder 5 from being damaged by excessive temperature due to the friction generated by repeated expansion and contraction.

[0050] It is worth mentioning that the rotation of the reciprocating screw 26 will synchronously drive the rotation of the rotating shaft 27, drive the rotation of the multiple fan blades 28, blow air to dissipate heat from the hydraulic cylinder 5, and further improve the cooling effect.

[0051] The side walls of the two lead screws 29 are both threadedly connected with the second sliders 39 , the side walls of the second sliders 39 are fixedly connected with the second auxiliary rods 40 , and the upper ends of the second auxiliary rods 40 are fixedly connected to the lower ends of the lifting seats 3 .

[0052] Furthermore, during lifting, the sliding of the first slider 7 will drive the rifle rod 32 to move, thereby driving the third bevel gear 33 to rotate, driving the fourth bevel gear 34 to rotate, and driving the lead screw 29 to rotate. At this time, the second slider 39 will slide upward, driving the second auxiliary rod 40 to slide upward, giving the lifting seat 3 an upward force, thereby further sharing the pressure of the hydraulic cylinder 5 and enhancing the auxiliary lifting effect.

[0053] In the present invention, the mounting seat 1 is first fixed to the orchard machine body by bolts, and then the agricultural machinery is fixedly mounted on the mounting frame 4 by bolts, and then the hydraulic cylinder 5 is driven to extend, driving the lifting seat 3 to rise, thereby driving the agricultural machinery installed on the mounting frame 4 to rise. Since the overall lifting device is installed on the orchard machine body, it is convenient to carry out maintenance and repair.

[0054] In the process of lifting the lifting seat 3 upward, the two connecting rods 8 will rotate away from each other, and the two first sliding blocks 7 will slide away from each other. In the process of the connecting rods 8 moving away from each other, the two cross bars 91 will be driven to move, and then the two sliding plugs 10 will be driven to slide away from each other. At this time, the air in the pump air chamber 101 will be squeezed into the slide cylinder 15 through the connecting pipe 18. The pressure in the slide cylinder 15 increases, which will push the slide plate 16 to slide upward, and then drive the first auxiliary rod 17 to move upward, giving the lifting seat 3 an upward force, thereby sharing the pressure of the hydraulic cylinder 5, assisting in lifting, and reducing the load of the hydraulic cylinder 5.

[0055] When the first slider 7 slides to the sidemost end of the slide groove 61, the first slider 7 cannot continue to slide, and the lifting seat 3 cannot continue to move upward. At this time, the lifting cannot continue, and the extension length of the hydraulic cylinder 5 is limited to avoid excessive extension of the hydraulic cylinder 5, which causes the agricultural machinery to be lifted too high and may cause damage to the frame of the orchard machine. At this time, the conductive plate 11 will also contact the conductive block 12, and the alarm 13 will sound to give a sound prompt. At this time, the staff can clearly know that the lifting has reached the maximum height and immediately stop the extension of the hydraulic cylinder 5.

[0056] When the hydraulic cylinder 5 suddenly fails and loses its supporting force, the lifting seat 3 will drop rapidly, thereby driving the two connecting rods 8 to rotate rapidly towards each other, driving the two cross bars 91 to move towards each other, and driving the two sliding plugs 10 to move rapidly towards each other. At this time, the two sliding plugs 10 will give the non-Newtonian fluid in the storage chamber 102 a momentary high pressure, and the non-Newtonian fluid will harden rapidly, thereby preventing the sliding plugs 10 from sliding towards each other, preventing the lifting seat 3 from falling rapidly, thereby preventing the sudden failure of the hydraulic cylinder 5 from causing the agricultural machinery to fall and be damaged.

[0057] In addition, during lifting, the sliding of the first slider 7 will drive the rifle rod 32 to move, and then drive the third bevel gear 33 to rotate, drive the fourth bevel gear 34 to rotate, and drive the screw 29 to rotate. At this time, the second slider 39 will slide upward, driving the second auxiliary rod 40 to slide upward, giving the lifting seat 3 an upward force, and further sharing the pressure of the hydraulic cylinder 5, thereby enhancing the auxiliary lifting effect.

[0058] In addition, the rotation of the lead screw 29 will drive the first bevel gear 30 to rotate, drive the second bevel gear 31 to rotate, drive the reciprocating lead screw 26 to rotate, and drive the moving block 24 to slide back and forth on the inner wall of the pump water tank 20. The moving block 24 will drive the rectangular block 21 to slide back and forth in a sealed manner through the push rod 25. Under the action of the rectangular block 21, external water will be drawn into the pump water tank 20 through the one-way water inlet pipe 22, and then the water in the pump water tank 20 will enter the sprinkler head 19 through the one-way water supply pipe 23. Finally, the water is sprayed out through the sprinkler head 19 to cool the hydraulic cylinder 5 and prevent the hydraulic cylinder 5 from being damaged due to excessive temperature caused by friction generated by repeated expansion and contraction. In addition, the rotation of the reciprocating lead screw 26 will synchronously drive the rotation of the rotating shaft 27, drive the rotation of multiple fan blades 28, blow air to dissipate heat from the hydraulic cylinder 5, and further improve the cooling effect.
