Description

Technical Field

[0001] The utility model relates to the technical field of sprayers, in particular to a retractable pedal structure and a sprayer. Background Art

[0002] A sprayer is a piece of agricultural equipment that uses an extendable boom to convert liquids (such as water or liquid medicine) into tiny droplets, which are then sprayed through a nozzle to form a mist. The sprayer chassis is equipped with a front crossbeam; above the front crossbeam, a removable boom mount is installed on the side of the cab for attachment to the boom. The sprayer also has a walkway, where the driver stands after boarding the vehicle and before entering the cab. This walkway also serves as a standing area for servicing other components, such as the boom mount and the medicine tank.

[0003] When the front crossbar of the chassis is raised, the boom mount rises and interferes with the upper step. The access step needs to be designed to avoid this. Furthermore, since the boom mount moves during use, this creates a gap (over 100mm wide) at the access step after the boom is extended, making it unsafe for workers to pass or work there. Utility Model Content

[0004] The utility model provides a retractable pedal structure and a sprayer to solve the technical problem that after the existing spray boom fixing seat moves, a gap will appear at the channel pedal, causing insecurity for operators to pass through or perform operations there.

[0005] The technical solution of the utility model to solve the above technical problems is as follows:

[0006] On the one hand, the utility model provides a retractable pedal structure, including a fixing seat for detachably connecting to a chassis assembly and a retractable pedal with one end slidably connected to the fixing seat, and the other end of the retractable pedal is used for detachably connecting to a spray rod fixing seat.

[0007] The beneficial effects of the present invention are as follows: when the spray boom is in a retracted state, the telescopic pedal remains stationary under the support of the spray boom fixing seat and the fixing seat, and the integrity of the channel is maintained; when the spray boom is extended and working, the spray boom fixing seat drives the telescopic pedal to move at the same time, and the telescopic pedal slides relative to the fixing seat; when the spray boom is extended and stationary in the working position, the telescopic pedal is always supported by the spray boom fixing seat and the fixing seat at the same time, and the integrity of the channel is maintained, thereby improving the existing technical problem that after the spray boom fixing seat moves, a gap will appear at the channel pedal, causing insecurity for operators to pass through or work here.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, the telescopic pedal includes a pedal and two clamping strips, one end of the pedal abuts against the upper side of the fixing seat, and the other end is used for detachable connection to the spray boom fixing seat, the two clamping strips are respectively located on both sides of the pedal, and the upper ends are fixedly connected to the pedal, and the lower ends of the two clamping strips are respectively clamped on both sides of the fixing seat.

[0010] The beneficial effect of adopting the above-mentioned further scheme is that when the movable spray boom fixing seat drives the telescopic pedal to move simultaneously, the pedal is driven by the movable spray boom fixing seat and moves relative to the fixing seat, the pedal is always supported by the fixing seat, and the two clamping strips are always clamped on both sides of the width direction of the fixing seat to limit and guide the telescopic pedal in the width direction through the fixing seat.

[0011] Furthermore, the telescopic pedal also includes two limit bars, one end of the two limit bars is fixedly connected to the lower ends of the two clamping bars, and the other ends extend toward each other and are slidably connected to the fixing base at the same time.

[0012] The beneficial effect of adopting the above further solution is that when the pedal moves relative to the fixing seat, the two limiting bars move relative to the fixing seat, so that the guiding and limiting effects are improved through the limiting bars.

[0013] Furthermore, limiting grooves are provided on both sides of the fixing seat, and the other ends of the two limiting strips are respectively adapted to and slidably connected to the two limiting grooves.

[0014] The beneficial effect of adopting the above-mentioned further scheme is that the limit groove forms a vertical limiting effect on the corresponding limit bar, which can prevent the telescopic pedal from separating upward from the fixed seat, ensuring the stability and continuity of the telescopic pedal during movement, and further improving the movement accuracy and guidance of the telescopic pedal through the precise guidance of the limit bar by the limit groove.

[0015] Furthermore, the pedal is provided with a plurality of through holes vertically therethrough, and the plurality of through holes are distributed at intervals.

[0016] The beneficial effect of adopting the above further solution is that the weight of the pedal is reduced by opening a plurality of through holes, and the energy consumption of the movement of the sprayer is relatively reduced.

[0017] Furthermore, an annular protrusion is fixed at the upper opening of each through hole.

[0018] The beneficial effects of adopting the above further solution are: by forming a reinforcing rib through the annular convexity, the structural strength of the pedal is improved, and an anti-slip effect is formed when the operator passes through, thereby enhancing the friction of the sole of the foot.

[0019] Furthermore, the fixing seat is connected with at least one No. 1 bolt, and each of the No. 1 bolts is used for threaded connection to the chassis assembly.

[0020] The beneficial effect of adopting the above further solution is: the stable installation of the fixing seat is achieved by each No. 1 bolt, thereby ensuring the stability of the telescopic pedal when sliding.

[0021] Furthermore, a connecting plate is provided at the other end of the telescopic pedal, and the connecting plate is used to be detachably connected to the spray rod fixing seat.

[0022] The beneficial effect of adopting the above further solution is that an installation space is formed by the bending state of the connecting plate, and the telescopic pedal is smoothly connected to the spray rod fixing seat.

[0023] Furthermore, the connecting plate is connected with a No. 2 bolt, and the No. 2 bolt is used to be connected to the spray boom fixing seat at the same time.

[0024] The beneficial effect of adopting the above further solution is: the telescopic pedal is connected to the spray boom fixing seat by the second bolt, and the movement of the spray boom fixing seat drives the telescopic pedal to move synchronously.

[0025] On the other hand, the utility model provides a sprayer, comprising the above-mentioned retractable pedal structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] 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.

[0035] On the one hand, the present invention provides a retractable pedal structure, which is described in detail below.

[0036] Example 1

[0037] like Figures 1 to 6 A retractable pedal structure includes a fixing seat 3 for detachably connecting to a chassis assembly 1 and a retractable pedal 4 with one end slidably connected to the fixing seat 3, and the other end of the retractable pedal 4 is used for detachably connecting to a spray boom fixing seat 2.

[0038] The beneficial effects of this embodiment are: when the spray boom is in the retracted state, the telescopic pedal 4 remains stationary under the support of the spray boom fixing seat 2 and the fixing seat 3, keeping the channel 11 intact; when the spray boom is extended and working, the spray boom fixing seat 2 drives the telescopic pedal 4 to move at the same time, and the telescopic pedal 4 slides relative to the fixing seat 3; when the spray boom is extended and stationary in the working position, the telescopic pedal 4 is always supported by the spray boom fixing seat 2 and the fixing seat 3 at the same time, and keeps the channel 11 intact, thereby improving the existing technical problem that after the spray boom fixing seat 2 moves, a gap will appear at the channel pedal, causing unsafe passage or operation for operators.

[0039] One end of the telescopic pedal 4 in the length direction is slidably connected to the fixing seat 3 , and the other end in the length direction is used for detachable connection to the spray rod fixing seat 2 .

[0040] As a specific solution of the above embodiment, the fixing seat 3 can be made of nylon material and can be installed on the end of the beam used to install the driving member of the spray boom fixing seat 2, and the beam can be a beam of the chassis assembly 1.

[0041] The telescopic pedal 4 moves along the width direction of the channel 11. The length of the telescopic pedal 4 is greater than the moving distance of the boom fixing base 2 to ensure that the telescopic pedal 4 does not separate from the fixing base 3 after moving, and the integrity of the channel 11 is ensured, filling the gap in the channel 11 after the boom fixing base 2 moves in the prior art.

[0042] During installation, a clearance hole for the telescopic pedal 4 to slide is provided at the bottom of the cab.

[0043] Example 2

[0044] like Figures 2 to 6On the basis of Example 1, the telescopic pedal 4 includes a pedal 41 and two clamping strips 42. One end of the pedal 41 abuts against the upper side of the fixing seat 3, and the other end is used for detachable connection to the spray boom fixing seat 2. The two clamping strips 42 are respectively located on both sides of the pedal 41, and the upper ends are fixedly connected to the pedal 41. The lower ends of the two clamping strips 42 are respectively clamped on both sides of the fixing seat 3.

[0045] The beneficial effect of adopting the preferred solution in the above embodiment is that when the movable spray boom fixing base 2 drives the telescopic pedal 4 to move simultaneously, the pedal 41 is driven by the movable spray boom fixing base 2 and moves relative to the fixing base 3. The pedal 41 is always supported by the fixing base 3, and the two clamping strips 42 are always clamped on both sides of the fixing base 3 in the width direction (i.e., the forward and backward direction of the sprayer) to limit and guide the telescopic pedal 4 in the width direction through the fixing base 3.

[0046] The pedal 41 and the clamping strip 42 can be fixed by welding or integrally formed. The two clamping strips 42 are respectively located on both sides of the pedal 41 in the width direction.

[0047] Example 3

[0048] like Figures 2 to 6 On the basis of embodiments 1 and 2, the telescopic pedal 4 also includes two limit bars 43, one end of the two limit bars 43 is fixedly connected to the lower ends of the two clamping bars 42, and the other ends extend toward each other and are slidably connected to the fixed seat 3 at the same time.

[0049] The beneficial effect of adopting the preferred solution in the above embodiment is that when the pedal 41 moves relative to the fixing seat 3, the two limiting bars 43 move relative to the fixing seat 3, so as to improve the guiding and limiting effects through the limiting bars 43.

[0050] The pedal 41 , the clamping bar 42 and the limiting bar 43 may be fixed by welding or manufactured in an integral molding manner.

[0051] Example 4

[0052] like Figures 2 to 4 On the basis of embodiments 1-3, limiting grooves 31 are provided on both sides of the fixing seat 3, and the other ends of the two limiting strips 43 are respectively adapted and slidably connected to the two limiting grooves 31.

[0053] The beneficial effect of adopting the preferred scheme in the above embodiment is that the limit groove 31 forms a vertical limiting effect on the corresponding limit strip 43, which can prevent the telescopic pedal 4 from separating upward from the fixed seat 3, ensuring the stability and continuity of the telescopic pedal 4 during the movement process, and further improving the movement accuracy and guidance of the telescopic pedal 4 through the precise guidance of the limit strip 43 by the limit groove 31.

[0054] At the same time, the limiting groove 31 provides a more reliable limiting and guiding structure, and effectively prevents the telescopic pedal 4 from shaking or deflecting during the movement.

[0055] As a parallel solution of the above embodiment, a slot is provided on the upper side of the fixing seat 3, which may be a stepped slot or a dovetail slot, and the pedal 41 is fixed with a block adapted to and slidably connected to the slot, so as to limit the movement of the block through the slot, so that the telescopic pedal 4 can move in the extension direction of the spray boom.

[0056] Example 5

[0057] like Figure 3 and Figure 4 On the basis of embodiments 1-4, a plurality of through holes 411 are vertically penetrated through the pedal 41, and the plurality of through holes 411 are distributed at intervals.

[0058] The beneficial effect of adopting the preferred solution in the above embodiment is that the weight of the pedal 41 is reduced by opening a plurality of through holes 411, thereby relatively reducing the energy consumption of the movement of the sprayer.

[0059] The through hole 411 may be a circular hole or a polygonal hole.

[0060] Example 6

[0061] like Figure 3 and Figure 4 On the basis of embodiments 1-5, a ring protrusion 412 is fixed at the upper opening of each through hole 411.

[0062] The beneficial effect of adopting the preferred solution in the above embodiment is that the annular protrusion 412 forms a reinforcing rib, thereby improving the structural strength of the pedal 41, forming an anti-slip effect when the operator passes through, and enhancing the friction of the sole of the foot.

[0063] Example 7

[0064] like Figure 3 and Figure 4 On the basis of Examples 1-6, the fixing seat 3 is connected with at least one No. 1 bolt 5 , and each No. 1 bolt 5 is used for threaded connection to the chassis assembly 1 .

[0065] The beneficial effect of adopting the preferred solution in the above embodiment is that the stable installation of the fixing seat 3 is achieved by each No. 1 bolt 5, thereby ensuring the stability of the telescopic pedal 4 when sliding.

[0066] As a specific solution of the above embodiment, a No. 1 insertion hole is formed through the fixing base 3 for the rod of the No. 1 bolt 5 to pass through. The No. 1 insertion hole is a countersunk hole for the head of the No. 1 bolt 5 to enter, so as to prevent the No. 1 bolt 5 from obstructing the movement of the pedal 41.

[0067] Example 8

[0068] like Figure 2 and Figure 5 On the basis of embodiments 1-7, a connecting plate 413 is provided at the other end of the telescopic pedal 4, and the connecting plate 413 is used for detachably connecting to the spray rod fixing seat 2.

[0069] The beneficial effect of adopting the preferred solution in the above embodiment is that, by forming an installation space through the bending state of the connecting plate 413 , the telescopic pedal 4 is smoothly connected to the spray rod fixing seat 2 .

[0070] As a specific solution of the above embodiment, the connecting plate 413 is in an upwardly bent state.

[0071] As a parallel solution, the connecting plate 413 can also be arranged horizontally. And the connecting plate 413 can be integrally formed or welded to the telescopic pedal 4.

[0072] Example 9

[0073] like Figure 2 and Figure 5 On the basis of embodiments 1-8, the connecting plate 413 is connected with a No. 2 bolt 6, which is used to be connected to the spray boom fixing seat 2 at the same time.

[0074] The beneficial effect of adopting the preferred solution in the above embodiment is that the telescopic pedal 4 is connected to the spray boom fixing base 2 by the second bolt 6, and the movement of the spray boom fixing base 2 drives the telescopic pedal 4 to move synchronously.

[0075] As a specific solution of the above embodiment, a second insertion hole is formed through the connecting plate 413 for the rod of the second bolt 6 to pass through. In addition, a fixing hole is formed on the vertical rod of the spray boom fixing base 2, which is connected to the second insertion hole to allow the rod of the second bolt 6 to pass through at the same time.

[0076] A nut is bolted to the rod of the No. 2 bolt 6 to lock the connecting plate 413 .

[0077] On the other hand, the present invention provides a sprayer, which is described in detail below.
