Description

Technical Field

[0001] This invention belongs to the field of irrigation equipment, specifically relating to an automatic telescopic wing-type field truss sprinkler irrigation machine. Background Technology

[0002] Currently, self-propelled field irrigation equipment mainly adopts a spliced ​​fixed truss, with sprinkler pipes suspended at the bottom of the truss. The sprinkler pipes are connected to a water supply pump to irrigate the field by spraying. Compared with the extensive irrigation mode of flood irrigation, this equipment can give the soil time to absorb water, thereby effectively utilizing water resources and reducing runoff waste.

[0003] However, fixed trusses need to be assembled on-site in the farmland and disassembled and transported after irrigation. The preparation time before and after irrigation is long, which is not conducive to improving irrigation efficiency. Summary of the Invention

[0004] To address the problems existing in the prior art, the present invention provides an automatic telescopic wing-type field truss irrigation machine, which can realize the automatic extension and retraction of the truss, effectively saving irrigation time and improving irrigation efficiency.

[0005] The specific technical solution adopted in this invention is as follows:

[0006] An automatic telescopic wing-type field truss irrigation machine includes a vehicle body equipped with wheels. A wing-type truss mechanism is symmetrically arranged on both sides of the vehicle body, and spray pipes are installed on the truss structure. The truss mechanism includes a fixed truss and a telescopic truss. The fixed truss has a tubular structure with an inverted triangular radial cross-section. The telescopic truss is fitted inside the fixed truss and has sliding and telescopic freedom with the fixed truss via a drive mechanism. The lower chord of the telescopic truss and the fixed truss serves as the spray pipes.

[0007] The telescopic truss is a triangular tubular structure with three sets of nested structures, namely a first truss, a second truss, and a third truss. The first truss is nested inside the second truss, the second truss is nested inside the third truss, and the third truss is nested inside the fixed truss. Support rods are provided on the outer trusses, and support rollers are provided on the support rods. The support rollers form rolling supports with the upper chord and lower chord of the inner truss.

[0008] The drive mechanism includes an extension winch and a retraction winch. The support rods of the second truss, third truss, and fixed truss are each equipped with a return roller. The extension winch is connected to the third truss via a third connecting rope, which passes over the return roller located at the end of the fixed truss. The fixed truss is connected to the second truss via a second connecting rope, which passes over the return roller located at the end of the third truss. The third truss is connected to the first truss via a first connecting rope, which passes over the return roller located at the end of the second truss.

[0009] The retractable winch is connected to the first truss via a retractable connecting rope, which is inserted into the cavity of the fixed truss and the telescopic truss.

[0010] Support rods are provided on three sides of the truss, and the support rollers on the outer truss support rods form a slide for the inner truss to extend and retract.

[0011] A plug-in joint is provided between the inner and outer trusses. The plug-in joint includes a male plug rod and a female plug rod, both of which are J-shaped tubular structures. The male plug rod is set on the spray pipe of the inner truss, and the female plug rod is set on the spray pipe of the outer truss. The male plug rod can be inserted into the cavity of the female plug rod of the outer truss as the inner truss moves. Multiple sets of sealing rings are provided on the outer tube wall of the male plug rod, and the female plug rod and the male plug rod form a sealed connection by means of the sealing rings.

[0012] The vehicle body is equipped with a switch valve connected to the water supply pipe of the water pump. The output end of the switch valve is connected to the spray pipe of the fixed truss via a water distribution pipe. Both the water supply pipe and the spray pipe are equipped with spray holes.

[0013] The beneficial effects of this invention are:

[0014] This invention uses a wing-type truss mechanism, which combines a fixed truss with multiple sets of nested telescopic trusses and uses a drive mechanism to achieve automatic extension and retraction of the telescopic trusses. Compared with the traditional fixed truss structure, it eliminates the steps of on-site assembly and disassembly, avoids tedious manual operations before and after irrigation, significantly shortens the irrigation preparation and finishing time, and allows the equipment to be put into operation quickly, effectively improving the efficiency of field irrigation.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0023] Specific implementation examples Figure 1 , Figure 2 and Figure 3 As shown, the present invention is an automatic telescopic wing-type field truss irrigation machine, including a vehicle body 1 equipped with wheels. A wing-type truss mechanism is symmetrically arranged on both sides of the vehicle body 1, and a spray pipe 2 is provided on the truss structure. The truss mechanism includes a fixed truss 3 and a telescopic truss. The fixed truss 3 has a tubular structure and its radial cross-section is an inverted triangle. The telescopic truss is fitted inside the fixed truss 3. The telescopic truss has the freedom to slide and extend with the fixed truss 3 by means of a drive mechanism. The lower chord of the telescopic truss and the fixed truss 3 serves as the spray pipe 2.

[0024] When in use, this invention uses a vehicle 1 with wheels to move to the field to be irrigated. The telescopic truss is pulled out by the drive mechanism to form a wing-shaped truss structure. The telescopic structure is achieved by the cooperation of the fixed truss 3 and the telescopic truss. Compared with the traditional fixed truss structure, it eliminates the steps of on-site assembly and disassembly, avoids tedious manual operations before and after irrigation, significantly shortens the irrigation preparation and finishing time, and allows the equipment to be put into operation quickly, effectively improving the irrigation efficiency of the field.

[0025] Furthermore, such as Figure 3 As shown, the telescopic truss is a triangular tubular structure with three sets of nested structures, namely the first truss 4, the second truss 5, and the third truss 6. The first truss 4 is fitted inside the second truss 5, the second truss 5 is fitted inside the third truss 6, and the third truss 6 is fitted inside the fixed truss 3. Support rods 7 are provided on the outer truss, and support rollers 8 are provided on the support rods 7. The support rollers 8 and the upper chord and lower chord of the inner truss form rolling supports respectively.

[0026] The first truss 4, the second truss 5, and the third truss 6 of this invention are fitted together layer by layer, and finally the third truss 6 is fitted into the fixed truss 3. The driving mechanism of this invention includes an extending winch 9 and a retracting winch 10. The support rods 7 of the second truss 5, the third truss 6, and the fixed truss 3 are respectively provided with return rollers. The extending winch 9 is connected to the third truss 6 by a third connecting rope, which passes around the return roller located at the end of the fixed truss 3. The fixed truss 3 is connected to the second truss 5 by a second connecting rope, which passes around the return roller located at the end of the third truss 6. The third truss 6 is connected to the first truss 4 by a first connecting rope, which passes around the return roller located at the end of the second truss 5.

[0027] When the invention is opened in a wingspan manner, the third connecting rope is pulled by the extended winch 9. With the support of the return roller at the end of the fixed truss 3, the third truss 6 is pulled out from the inside of the fixed truss 3, that is, the third truss 6 is displaced relative to the fixed truss 3. At this time, since the second connecting rope is connected to the fixed truss 3 and is wound around the return roller at the end of the third truss 6, as the third truss 6 is displaced relative to the fixed truss 3, the second truss 5 is also pulled out from the inside of the third truss 6 by the pull of the second connecting rope. Similarly, the first truss 4 is also pulled out from the inside of the second truss 5. Thus, the wingspan opening of the truss mechanism is realized by the drive mechanism, which greatly shortens the preparation time for irrigation.

[0028] The extended winch 9 of the present invention has two sets of reels coaxially arranged, and the third connecting ropes of the truss mechanisms on the left and right sides are arranged in the two sets of reels with the same winding direction, thereby achieving the effect of driving the truss mechanisms on both sides simultaneously by means of one set of extended winches 9.

[0029] Furthermore, such as Figure 6 As shown, the retractable winch 10 is connected to the first truss 4 via a retractable connecting rope, which is inserted into the cavity of the fixed truss 3 and the telescopic truss. When the truss structure extends, the retractable winch 10 rotates in the reverse direction to release the retractable connecting rope, and the extended winch 9 rotates in the forward direction to pull the third connecting rope; when the truss structure retracts, the retractable winch 10 rotates in the forward direction to pull the retractable connecting rope, and the extended winch 9 rotates in the reverse direction to release the third connecting rope.

[0030] Furthermore, support rods 7 are provided on three sides of the truss, and support rollers 8 on the outer truss support rods 7 form sliding tracks for the extension and retraction of the inner truss. Figure 2As shown, each chord is equipped with two sets of support rollers 8. The two sets of support rollers 8 clamp the inner truss's rotating rod, thus forming a slide inside the outer truss, allowing the inner truss to extend and retract, and playing a role in limiting and stabilizing the sliding trajectory.

[0031] Furthermore, a plug-in connector is provided between the inner and outer trusses. The plug is located at the end of the stroke of the inner and outer trusses. While the water flow is transmitted through the connection, it also serves as a limiting function. The plug-in connector includes a male plug rod 11 and a female plug rod 12, both of which are J-shaped tubular structures. The male plug rod 11 is located on the spray pipe 2 of the inner truss, and the female plug rod 12 is located on the spray pipe 2 of the outer truss. The male plug rod 11 can be inserted into the cavity of the female plug rod 12 of the outer truss as the inner truss moves. Multiple sets of sealing rings are provided on the outer wall of the male plug rod 11, and the female plug rod 12 and the male plug rod 11 form a sealed connection with the sealing rings.

[0032] like Figure 4 As shown, when the inner truss extends outward, the male plug 11 at the tail end of the inner truss gradually approaches and inserts into the female plug 12 at the head end of the outer truss. The sealing ring on the male plug 11 ensures a stable connection after insertion and prevents water leakage. This allows the water flow from the outer truss spray pipe 2 to be guided into the inner truss spray pipe 2, thus achieving communication.

[0033] Furthermore, in use, the present invention utilizes a walking motor to drive the wheels of the vehicle body 1 to rotate. The vehicle body 1 is equipped with a switch valve connected to the water supply pipe of the water pump. The input end of the switch valve pulls the water supply pipe forward along with the vehicle body 1. The output end of the switch valve is connected to the spray pipe 2 of the fixed truss 3 via a distribution pipe. Both the water supply pipe and the spray pipe 2 are equipped with spray holes. The water supplied by the water supply pipe enters the distribution pipe after passing through the switch valve. The distribution pipe then delivers the water to the connected spray pipes 2, thus eliminating the need for pipe laying and allowing water delivery directly using the lower chord of the truss.
