[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.
[0024] Example 1
[0025] like Figure 1 , 2 As shown, the telescopic structure of the sprayer boom fixing seat of the present embodiment includes a fixing rod 1, a telescopic rod 2 and a locking mechanism 3. The fixing rod 1 is a hollow rod, one end of which is fixedly assembled with a chassis bracket (denoted by D in the figure), one end of the telescopic rod 2 is inserted into the other end of the fixing rod 1, and the other end of the telescopic rod 2 is connected to the spray boom fixing seat 4. The locking mechanism 3 is installed at the other end of the fixing rod 1, and is used to lock or unlock the telescopic rod 2 when the telescopic rod 2 is extended or retracted into the fixing rod 1.
[0026] The usage process is as follows:
[0027] The telescopic rod 2 can be extended or shortened relative to the fixed rod 1, and then the position of the telescopic rod 2 is fixed and maintained by the locking mechanism 3 after extension or shortening. Specifically, when extension is required, the locking mechanism 3 is released to lock the telescopic rod 2, and then the telescopic rod 2 is pulled out relative to the fixed rod 1, and then locked and fixed by the locking mechanism 3. When retracting is required, the locking mechanism 3 is unlocked, and the telescopic rod 2 is pushed in relative to the fixed rod 1, and then locked and fixed by the locking mechanism 3. The whole structural design is simple and reasonable, the operation is simple and convenient, the spray rod can be retracted, which is conducive to the recovery of the spray rod, and the whole machine has good passability.
[0028] In this embodiment, one end of the telescopic rod 2 can pass through the other end of the fixed rod 1, and a limit block (indicated by A in the figure) is provided at one end of the telescopic rod 2 to prevent the telescopic rod 2 from separating from the fixed rod 1.
[0029] As a preferred embodiment, the fixed rod 1 is a square tube component, and the telescopic rod 2 is a square rod.
[0030] In the above embodiment, the fixed rod 1 is a square tube member, that is, a square tube profile. The telescopic rod 2 is a square rod adapted to the fixed rod 1, and when the telescopic rod 2 is inserted into and telescoped with the fixed rod 1, relative rotation will not occur.
[0031] In this embodiment, the telescopic rod 2 is a square tube member, and square tube profiles of suitable sizes on the market can be used, which is convenient to obtain.
[0032] In this embodiment, one end of the fixed rod 1 is welded and fixed to the chassis bracket, and the other end of the telescopic rod 2 is welded to a plate-shaped spray rod connecting seat perpendicular thereto.
[0033] As a preferred embodiment, Figure 3 As shown, the locking mechanism 3 includes a mounting seat 31, a locking pin 32 and an elastic member 33. The mounting seat 31 is fixed to one side of the other end of the fixed rod 1. The locking pin 32 passes through the mounting seat 31 and the through holes adapted to the side ends of the fixed rod 1, and is perpendicular to the side ends of the telescopic rod 2. The elastic member 33 is connected between the mounting seat 31 and the locking pin 32. Both ends of one side of the telescopic rod 2 are respectively provided with locking holes 21 adapted to the locking pin 32. The telescopic rod 2 can be telescopically moved relative to the fixed rod 1 to any one of the locking holes 21 to align with the locking pin 32. One end of the locking pin 32 is inserted into any one of the locking holes 21 aligned with it.
[0034] In the above embodiment, the two locking holes 21 define two limit positions of extension or shortening of the telescopic rod 2. When the telescopic rod 2 is shortened to the limit position, the locking hole 21 at the other end thereof is aligned with the locking pin 32. When the telescopic rod 2 is extended to the limit position, the locking hole 21 at one end thereof is aligned with the locking pin 32. Since the elastic member 33 is always in a compressed state, a force tending to the side end of the telescopic rod 2 is applied to the locking pin 32. Therefore, when the telescopic rod 2 is extended or shortened, the locking pin 32 always slides relatively against the side end of the telescopic rod 2. When any locking hole 21 faces the locking pin 32, the locking pin 32 will extend out and be inserted into the locking hole 21 under the action of the elastic member 33 to achieve locking. When unlocking is required, the locking pin 32 is pulled outward to disengage the locking pin 32 from the locking hole 21. The whole operation process is simple and quick.
[0035] As a preferred embodiment, the above-mentioned mounting seat 31 is a door-shaped sheet metal part, and connecting ear plates are respectively provided at both ends of its open end, and the above-mentioned connecting ear plates are fit and fixed to the side ends of the above-mentioned fixing rod 1. The above-mentioned locking pin shaft 32 passes through the middle part of the closed end of the above-mentioned mounting seat 31 and the above-mentioned through hole. A limiting portion 321 is provided in the middle part of the above-mentioned locking pin shaft 32, and the above-mentioned elastic member 33 is connected between the above-mentioned limiting portion 321 and the closed end of the above-mentioned mounting seat 31.
[0036] In the above embodiment, the mounting seat 31 has a simple structural design and is easy to assemble, which is beneficial to the rapid assembly of the locking pin shaft 32 .
[0037] As a preferred embodiment, a guide sleeve is provided at the outer opening of the through hole, and one end of the locking pin 32 passes through the guide sleeve.
[0038] In the above embodiment, since the fixing rod 1 is a square tube member with a low side wall thickness, the locking pin 32 is easily skewed during the insertion and movement process, therefore, a guide sleeve is provided on the outside of the through hole, and the locking pin 32 is inserted through the guide sleeve. Since the guide sleeve has a certain length, the locking pin 32 plays a good guiding role when moving along the guide sleeve, thereby preventing the locking pin 32 from being skewed. The diameter of the locking pin 32 is close to the inner diameter of the guide sleeve, and the gap between the two is small.
[0039] In this embodiment, the elastic member 33 may be a spring, and two ends of the spring may abut against the closed end of the mounting seat 31 and the limiting portion 321 respectively.
[0040] In this embodiment, a handle 322 is provided at the other end of the locking pin 32. When operating the locking pin 32 to be pulled outward, external force can be applied through the handle 322.
[0041] As a preferred embodiment, a limiting groove 22 is provided on one side of the telescopic rod 2 along its length direction, and the limiting groove 22 passes through the two locking holes 21 .
[0042] In the above embodiment, during the extension and retraction of the telescopic rod 2, since the limit groove 22 passes through the two locking holes 21, the end of the locking pin 32 is always located in the limit groove 22, and as the telescopic rod 2 is extended and retracted, the locking pin 32 will move relatively along the limit groove 22, and will inevitably move to the hole aligned with the locking hole 21 for insertion, and no misalignment will occur.
