Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mixer trucks, in particular to a discharging device and an engineering vehicle. Background Art
[0002] When the concrete mixer truck is working, the material sliding out of the discharge chute is sent to the hopper of the pump truck to realize the pouring of concrete. Because the construction area is generally subject to certain geographical space restrictions, the vehicle cannot be parked and placed in any direction, so the angle of the discharge chute needs to be rotated.
[0003] In the related art, the bracket of the discharge chute can be rotatably connected to the fixed plate to realize the rotation function of the discharge chute. Here, the operating handle is generally clamped on the bracket of the discharge chute and the fixed plate to limit the relative rotation between the discharge chute and the fixed plate. When the discharge chute needs to be rotated, the operating handle is rotated to disengage from the fixed plate. However, when the discharge chute needs to be rotated, the operator needs to drag the operating handle with one hand to prevent the operating handle from accidentally falling back onto the fixed plate under the action of gravity, and rotate the discharge chute with one hand. This operation is cumbersome and requires the operator to cooperate with both hands, which is time-consuming and laborious.
[0004] In response to the problem of the operating handle falling back accidentally, some technologies have been disclosed. The operating handle is restricted by setting a limit structure. During operation, the user presses the pressing part to put the limit structure in the avoidance position. When the operating handle is rotated to the specified position, the pressing part is pressed again to put the limit structure in the limit position. In this way, the user needs to press the pressing part twice, and the limit structure cannot automatically reset to the limit position, which increases the user's operating steps. Utility Model Content
[0005] The utility model aims to at least solve the technical problem that the limiting structure existing in the prior art or related art cannot be automatically reset to the limiting position.
[0006] To this end, a first aspect of the utility model is to provide a discharging device.
[0007] A second aspect of the utility model provides an engineering vehicle.
[0008] The unloading device provided by the utility model comprises: a rotating bracket, which can rotate; a unloading chute, which is installed on the rotating bracket and can rotate with the rotating bracket; a fixing member, which is connected to the rotating bracket, and the fixing member includes a limiting structure; a positioning handle, which is rotatably connected to the rotating bracket and can be rotated into the limiting structure and be in a locking position, or rotated away from the limiting structure; a limiting member, which is arranged on the rotating bracket and can move between a limiting position and an avoidance position, and when the limiting member is in the limiting position, it can limit the rotation of the positioning handle; a resetting member, which is connected to the limiting member and can reset the limiting member to the limiting position.
[0009] The unloading device provided by the utility model, when the positioning handle needs to be adjusted, an external force is used to push the limit member to the avoidance position, and after the positioning handle is rotated, the limit member can automatically reset to the restricted position under the action of the reset member, thus eliminating the need for the user to adjust the position of the limit member twice, thereby simplifying the user's operation process.
[0010] In some embodiments, optionally, the limit member includes a ball, which is arranged on the movement path of the positioning handle, wherein when the positioning handle moves on the movement path, the positioning handle can contact the ball and provide a second force to the ball to compress the reset member, and the force of the reset member on the ball is the first force. When the second force is greater than the first force, the ball can move to the avoidance position, and when the second force is less than or equal to the first force, the ball can be reset to the restricted position.
[0011] In this embodiment, since the ball has a smooth surface, when the user turns the positioning handle, the ball can press the reset member only by providing a slightly larger force. When the second force of the ball pressing the reset member is greater than the first force of the reset member on the ball, the limit member can press the reset member and move to the avoidance position. At this time, the positioning handle can be rotated. When the position of the positioning handle is fixed, the reset member can reset the limit member so that the limit member can be in the restricted position. When the positioning handle is only subjected to gravity, under the gravity of the positioning handle, the second force is much smaller than the first force and is insufficient to move the positioning handle to the avoidance position. In this way, the operating handle will not fall back accidentally. The user does not need to manually adjust the position of the limit member during the whole process. The user only needs to turn the positioning handle with force, which makes the user operation more convenient.
[0012] In some embodiments, optionally, the limit member includes a limit rod, the limit rod includes a first end and a second end, the first end is used to limit the rotation of the positioning handle, the reset member includes a reset spring, and the unloading device also includes: a sleeve, which is arranged on the rotating bracket, and the limit rod passes through the sleeve; the reset spring is arranged in the sleeve, and the reset spring is arranged around the outside of the limit rod, the reset spring can provide a force to the limit member and reset the first end of the limit rod to the limit position; the handle is connected to the second end of the limit rod, can pull the limit rod, and move the first end of the limit member to the avoidance position.
[0013] In this embodiment, when adjusting the limit rod to the avoidance position, the user needs to manually pull the handle, and when adjusting the limit position, it can be reset by the reset spring. Compared with the limit method of the ball, the limit rod has a better limit effect. In addition, at least part of the limit rod and the reset spring are arranged in the sleeve, which can play a certain guiding role for the limit rod.
[0014] In some embodiments, the handle optionally includes a pull ring or a pull rod.
[0015] In some embodiments, optionally, the limiting structure includes a limiting groove, and the positioning handle can be limited in the limiting groove.
[0016] In this embodiment, a limiting groove is used as a limiting structure. This limiting method is relatively simple. When opening the positioning handle, it is only necessary to rotate the positioning handle in the opposite direction, which makes the operation easier.
[0017] In some embodiments, optionally, the fixing member is a fixed disc, the number of the limiting grooves is greater than or equal to 6, and the plurality of limiting grooves are arranged at intervals along the circumference of the fixed disc.
[0018] In this embodiment, a plurality of limiting grooves are arranged at intervals along the circumference of the fixed disc, so that the positioning handle can be locked when the rotating bracket rotates at multiple angles. For example, the number of limiting grooves is equal to 6, which are evenly distributed in the circumference of the fixed disc, so that the rotating bracket can rotate 60° each time, and the positioning handle and the limiting groove can be achieved. For another example, the number of limiting grooves is equal to 12, which are evenly distributed in the circumference of the fixed disc, so that the rotating bracket can rotate 30° each time, and the positioning handle and the limiting groove can be achieved.
[0019] In some embodiments, optionally, the limiting structure includes a first engaging portion, and a second engaging portion is provided on the positioning handle, and the first engaging portion and the second engaging portion can engage with each other.
[0020] In this embodiment, compared with the limiting groove limiting method, the locking limiting effect is better, and the positioning handle is not easy to be separated from the limiting groove on a bumpy road. For example, the first locking portion and the second locking portion are mutually matched hooks.
[0021] In some embodiments, optionally, one end of the discharge chute is rotatably connected to the rotating bracket, and the discharge device also includes an adjustment device connected to the end of the discharge chute away from the rotating bracket, which can drive the discharge chute to rotate relative to the rotating bracket to adjust the inclination angle of the discharge chute.
[0022] In this embodiment, the inclination angle of the discharge chute can be adjusted by providing an adjusting device, thereby adjusting different feeding speeds. Optionally, the adjusting device is an adjusting oil cylinder.
[0023] The second aspect of the utility model provides an engineering vehicle, and the engineering vehicle provided by the utility model includes a discharge device as in any embodiment of the first aspect of the utility model. Since the engineering vehicle provided by the utility model includes a discharge device as in any embodiment of the first aspect of the utility model, it has all the beneficial effects of the discharge device as in any embodiment of the first aspect of the utility model. Optionally, the engineering vehicle includes a mixer truck, a transport truck, etc.
[0024] In some embodiments, optionally, the engineering vehicle further includes: a backstage; a unloading bracket connected to the backstage, and a unloading device connected to the unloading bracket.
[0025] In this embodiment, the stability of the unloading device can be improved by supporting the unloading device at the backstage.

DETAILED DESCRIPTION
[0049] In order to more clearly understand the above aspects, features and advantages of this embodiment, the embodiment is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of this application and the features in the embodiments can be combined with each other without conflict.
[0050] In the following description, many specific details are set forth to facilitate a full understanding of the present embodiment. However, the present embodiment may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present embodiment is not limited to the specific embodiments disclosed below.
[0051] It should be understood that most of the current mixer trucks use a flange with teeth in the rotation limit structure of the discharge chute, and then use a rotatable positioning handle for limiting. In the process of fixing the positioning handle, the general method is to use bolts to tighten the positioning handle so that the positioning handle maintains friction with the steel plates on both sides, so that after the positioning handle is lifted, it can remain in the air and the positioning handle will not fall when the discharge chute is rotated. However, in order to maintain the friction of the handle, the bolts are generally pressed very tightly, resulting in a heavy positioning handle for the new car at the beginning. However, after a period of use, the friction becomes smaller due to wear, and the positioning handle will not be able to be fixed. It will fall down when it is lifted, and it must be held, while the discharge chute must be rotated at the same time, resulting in the phenomenon that two hands are not enough during the rotation operation. In addition, after the friction of the positioning handle becomes smaller, the positioning handle will jump, and the problem of the positioning handle jumping out of the lock may occur when driving on bumpy roads.
[0052] like Figure 1 , Fig.13 , Fig.14 , Fig.15 , Fig.16 and Fig.17 As shown, the unloading device 1 provided in this embodiment includes a rotating bracket 11, a unloading chute 12, a positioning handle 13, a limiting member 14, a resetting member 15 and a fixing member 18. The rotating bracket 11 can rotate; the unloading chute 12 is installed on the rotating bracket 11 and can rotate with the rotating bracket 11; the fixing member 18 is connected to the rotating bracket 11, and the fixing member 18 includes a limiting structure 182; the positioning handle 13 is rotatably connected to the rotating bracket 11, and can be rotated into the limiting structure 182 and be in a locked position, or rotated away from the limiting structure 182 and be in a released position, that is, it can be rotated between the locked position and the released position. Figure 1 , Fig.11 and Fig.13 The position of the positioning handle 13 shown is the locked position. Fig.12 and Fig.14 The position of the positioning handle 13 shown is the release position. When the positioning handle 13 is rotated to the locking position, the rotation of the rotating bracket 11 can be restricted. When the positioning handle 13 is rotated to the release position, the rotation of the rotating bracket 11 can be allowed. Fig.13 and Fig.14 As shown, the limiting member 14 is disposed on the rotating bracket 11 and can move between a limiting position and an avoidance position. Figure 4 and Figure 8 The position of the limiter 14 shown is the limiting position, and the avoidance position, that is, the limiter 14 moves to the right, allowing the positioning handle 13 to pass. When the limiter 14 is in the limiting position, the rotation of the positioning handle 13 can be restricted. When the limiter 14 is in the avoidance position, the positioning handle 13 is allowed to rotate. Figure 4 As shown, the reset member 15 is connected to the limiting member 14 and can reset the limiting member 14 to the limiting position.
[0053] The unloading device 1 provided by the utility model, when the positioning handle 13 needs to be adjusted, the limit member 14 is pushed to the avoidance position by external force, and after the positioning handle 13 is rotated, the limit member 14 can be automatically reset to the restricted position under the action of the reset member 15, so that the user does not need to adjust the position of the limit member 14 twice, thereby simplifying the user's operation process.
[0054] In some embodiments, optionally, Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the limiting member 14 includes a ball 142, which is arranged on the movement path of the positioning handle 13, wherein when the positioning handle 13 moves on the movement path, the positioning handle 13 can contact the ball 142 and provide a second force to the ball 142 to press the reset member 15, and the force of the reset member 15 on the ball 142 is the first force, when the second force is greater than the first force, the ball 142 can move to the avoidance position, and when the second force is less than or equal to the first force, the ball 142 can be reset to the limit position, that is, Figure 4 The position of the middle ball 142.
[0055] In this embodiment, since the ball 142 has a smooth surface, when the user rotates the positioning handle 13, the ball 142 only needs to provide a slightly larger force, and the ball 142 can press the reset member 15. When the second force of the ball 142 pressing the reset member 15 is greater than the first force of the reset member 15 on the ball 142, the limit member 14 can press the reset member 15 and move to the avoidance position. At this time, the positioning handle 13 can be rotated. When the position of the positioning handle 13 is fixed, the reset member 15 can reset the limit member 14 so that the limit member 14 can be in the restricted position. When the positioning handle 13 is only subjected to gravity, under the gravity of the positioning handle 13, the second force is much smaller than the first force, which is not enough to make the positioning handle 13 move to the avoidance position. In this way, the operating handle will not fall back accidentally. The whole process does not require the user to manually adjust the position of the limit member 14, and only needs to forcefully rotate the positioning handle 13, making the user operation more convenient.
[0056] In some embodiments, optionally, Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, the limit member 14 includes a limit rod 144, and the limit rod 144 includes a first end 1442 and a second end 1444. The first end 1442 is used to limit the rotation of the positioning handle 13. The reset member 15 includes a reset spring 152. The unloading device 1 also includes a sleeve 16, which is arranged on the rotating bracket 11. The limit rod 144 passes through the sleeve 16; the reset spring 152 is arranged in the sleeve 16, and the reset spring 152 is arranged around the outer side of the limit rod 144. The reset spring 152 can provide a force to the limit member 14 and reset the first end 1442 of the limit member 14 to the restricted position; the handle 17 is connected to the second end 1444 of the limit rod 144, and can pull the limit rod 144 and move the first end 1442 of the limit rod 144 to the avoidance position.
[0057] In this embodiment, when adjusting the limit rod 144 to the avoidance position, the user needs to manually pull the handle 17, and when adjusting the limit position, it can be reset by the reset spring 152. The limit rod 144 has a better limit effect than the limit ball 142. In addition, at least part of the limit rod 144 and the reset spring 152 are arranged in the sleeve 16, which can play a certain guiding role for the limit rod 144.
[0058] In some embodiments, optionally, Fig. 9 and Fig.10 As shown, the handle 17 includes a pull ring 172 or a pull rod 174. It can also be a handle 17 with a self-locking function.
[0059] In some embodiments, optionally, the limiting structure 182 includes a limiting groove 1822 , and the positioning handle 13 can be limited in the limiting groove 1822 .
[0060] In this embodiment, the limiting groove 1822 is used as the limiting structure 182. This limiting method is relatively simple. When opening the positioning handle 13, it is only necessary to rotate the positioning handle 13 in the opposite direction, which makes the operation easier.
[0061] In some embodiments, optionally, the fixing member 18 is a fixing disk 184 , the number of the limiting grooves 1822 is greater than or equal to 6, and the plurality of limiting grooves 1822 are arranged at intervals along the circumference of the fixing disk 184 .
[0062] In this embodiment, a plurality of limiting grooves 1822 are arranged at intervals along the circumference of the fixed disk 184, so that the positioning handle 13 can be locked when the rotating bracket 11 rotates at multiple angles. For example, the number of limiting grooves 1822 is equal to 6, which are evenly distributed in the circumference of the fixed disk 184, so that the rotating bracket 11 can rotate 60° each time, and the positioning handle 13 and the limiting groove 1822 can be achieved. For another example, the number of limiting grooves 1822 is equal to 12, which are evenly distributed in the circumference of the fixed disk 184, so that the rotating bracket 11 can rotate 30° each time, and the positioning handle 13 and the limiting groove 1822 can be achieved.
[0063] In some embodiments, optionally, Fig.15 As shown, the limiting structure 182 includes a first engaging portion 1824 , and the positioning handle 13 is provided with a second engaging portion 132 , and the first engaging portion 1824 and the second engaging portion 132 can engage with each other.
[0064] In this embodiment, compared with the limiting method of the limiting groove 1822, the locking limiting method has a better effect. On a bumpy road, the positioning handle 13 is not easy to be separated from the limiting groove 1822. For example, the first locking portion 1824 and the second locking portion 132 are mutually matched hooks. Of course, the locking limiting method and the limiting groove 1822 limiting method can also be adopted at the same time, so that the limiting effect is better.
[0065] In some embodiments, Figure 1 As shown, optionally, one end of the discharge chute 12 is rotatably connected to the rotating bracket 11, and the discharge device 1 also includes an adjustment device 19, which is connected to the end of the discharge chute 12 away from the rotating bracket 11, and can drive the discharge chute 12 to rotate relative to the rotating bracket 11 to adjust the inclination angle of the discharge chute 12.
[0066] In this embodiment, the inclination angle of the discharge chute 12 can be adjusted by providing an adjusting device 19, thereby adjusting different feeding speeds. Optionally, the adjusting device 19 is an adjusting oil cylinder.
[0067] The unloading device 1 of the utility model, such as Fig.13 As shown, when the positioning handle 13 is in the lower position, the limiting member 14 prevents the positioning handle 13 from jumping up. Fig.14 As shown, when the positioning handle 13 is flipped up and unlocked, the limiting member 14 can prevent the positioning handle 13 from falling down until the work is completed and an external force is applied to release the positioning handle 13.
[0068] The unloading device 1 of the utility model mainly adopts two limiting modes of the positioning handle 13. The first mode is to use a spring ball mechanism, open a thread hole at an appropriate position on the side wall of the rotating bracket 11 where the positioning handle 13 is installed; install a spring ball mechanism; when the positioning handle 13 is locked, the steel ball can limit the positioning handle 13; when the positioning handle 13 is flipped up, the positioning handle 13 presses the steel ball to retract and release the limit; after the positioning handle 13 flips over the steel ball, the steel ball pops out and fixes the positioning handle 13 in the flipped position, and the rotating bracket 11 can rotate freely; until an external force is applied to press the positioning handle 13 downward to press the steel ball back, and the positioning handle 13 falls back to the locked position. The ball is approximately a standard part, which is common in the market, cheap and reliable in structure. The second method is to use the indexing pin 25 for limiting the position: drill a threaded hole at an appropriate position on the side wall of the rotating bracket 11 for installing the positioning handle 13; install the indexing pin 25, which includes a limiting rod 144, a reset spring 152 and a handle 17. When locked, the limiting rod 144 is in a pop-up state to limit the positioning handle 13. When the positioning handle 13 needs to be flipped up, pull out the limiting rod 144 and release the positioning handle 13 to limit the position; when the flipping is completed, release the handle 17, the limiting rod 144 automatically rebounds, fixes the positioning handle 13 in the flipped up position, and the rotating bracket 11 can rotate freely; when released, pull the handle 17, and the positioning handle 13 falls down by gravity and returns to the locked position. The indexing pin 25 is a standard part, mainly including reset-type indexing pins, such as Fig.18 As shown, and self-locking indexing pins, such as Fig.19 As shown, the common market price is cheap and the structure is reliable. Fig.18 and Fig.19 In the figure, l1, l2, l3, l4, l5, d1, d2, d4 and e represent the sizes of different parts.
[0069] The working principle of the unloading device 1 of the utility model is:
[0070] 1. The discharge chute 12 is installed on the rotating bracket 11 and can rotate with the rotating bracket 11 so as to guide the direction of the mixer truck when discharging.
[0071] 2. The positioning flange is fixed on the frame, and the positioning handle 13 is fixed on the rotating bracket 11. When the positioning handle 13 is inserted into the limiting groove 1822 of the positioning flange, the rotation of the rotating bracket 11 is locked.
[0072] 3. When the positioning handle 13 is turned up and disengaged from the limiting groove 1822 of the positioning flange, the rotating bracket 11 can rotate freely.
[0073] 4. When the positioning handle 13 is turned up, it will automatically fall down due to gravity, affecting the operation. Therefore, a spring top ball or indexing pin 25 is used to limit the position when it is turned up to avoid automatic falling, so that the construction personnel can freely rotate the discharge chute 12.
[0074] 5. After the construction is completed, loosen the positioning handle 13, drop it to the limit groove 1822 of the positioning flange, lock the rotation of the discharge chute 12, and ensure driving safety.
[0075] The beneficial effects of the unloading device 1 of the utility model are:
[0076] 1. Fix the position of the positioning handle 13 at the lowest cost to rotate the discharge chute 12;
[0077] 2. When the positioning handle 13 locks the discharge chute 12, the positioning handle 13 is prevented from bouncing up due to vehicle bumps, thereby maintaining driving safety;
[0078] 3. When the positioning handle 13 is turned up and the discharge chute 12 rotates, the position of the positioning handle 13 does not slide down, and the construction personnel do not need to hold the positioning handle 13 when rotating the discharge chute 12, which is convenient for operation;
[0079] 4. Accessories are easily available in the market and the structure is reliable.
[0080] like Figure 6 As shown, the second aspect of the utility model provides an engineering vehicle 2, the engineering vehicle 2 provided by the utility model includes a discharge device 1 as in any embodiment of the first aspect of the utility model, the engineering vehicle 2 also includes a backstage 22 and a discharge bracket 24, the backstage 22 and the discharge bracket 24 are connected, and the discharge device 1 is connected to the discharge bracket 24. The backstage 22 supports the discharge device 1, so that the stability of the discharge device 1 can be improved. Since the engineering vehicle 2 provided by the utility model includes the discharge device 1 as in any embodiment of the first aspect of the utility model, it has all the beneficial effects of the discharge device 1 as in any embodiment of the first aspect of the utility model.
