Description

Technical Field

[0001] The invention relates to the technical field of construction waste treatment, in particular to a construction waste treatment device. Background Art

[0002] Construction waste refers to construction waste generated due to human or natural reasons in the project. Construction waste can be divided into construction slag, decoration waste, demolition waste, construction mud, etc.; according to the composition, construction waste can be divided into slag, concrete blocks, broken stones, brick and tile fragments, waste mortar, mud, asphalt blocks, waste plastics, waste metal, waste bamboo and wood, etc. The materials generated in the construction process need to be treated accordingly. The treatment of concrete waste generally starts with crushing it, and then the large pieces of concrete are placed in the crushing equipment with a bucket for crushing. The crushed concrete is screened and finally transported to the corresponding location by conveyor belt.

[0003] When pre-processing large pieces of construction waste, it is necessary to first use a breaker to break them, and then replace the bucket to pour the pre-processed waste into the crushing equipment. The replacement requires multiple operations, which causes this method to take a lot of time. When large pieces of waste are buried, the breaker needs to be replaced. Therefore, a construction waste processing device that is easy to switch between a breaker hammer and a shovel head is proposed. Summary of the invention

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present invention provides a construction waste treatment device, which has the following beneficial effects:

[0019] 1. The construction waste treatment device moves the waste treatment device to the corresponding location by moving the vehicle body, which is convenient for treating construction waste, and integrates crushing, screening and transmission into the vehicle body, thereby improving the waste treatment efficiency.

[0020] 2. The construction waste processing device has an adjusting component that can change the angles of the crushing bucket and the crushing hammer. When encountering large pieces of construction waste, the control adjusting component can quickly switch the crushing hammer, use the crushing hammer to crush the waste, and adjust again to rotate the crushing bucket to the bottom to shovel the waste in, thereby improving the crushing efficiency and dumping efficiency of the waste.

[0022] 4. In the construction waste processing device, the moving component can change the position of the breaker hammer on the connecting seat. When the position of the breaker hammer needs to be fine-tuned when crushing the waste, the position of the breaker hammer on the Y-axis of the connecting seat is changed by the moving component, and the hydraulic cylinder changes the position of the breaker hammer on the X-axis of the connecting seat, so that the user can crush the waste conveniently without adjusting the position of the vehicle body many times.

[0023] 5. The construction waste treatment device connects the external water source to the water pipe while the crushing bucket shovels in the waste, and sprays water through the nozzle on the water pipe, so as to reduce dust at the feeding port of the crushing bucket. The connecting seat 2 can be rotated to change the angle of the nozzle, so that dust can be reduced in the area when the crushing hammer is working.

[0024] 6. The construction waste processing device can drive the baffle at the bottom of the screen box to open the discharge port at the bottom of the screen box when the support arm rotates, and then when the support arm rotates the crushing bucket to the top of the screen box, the baffle is also fully opened accordingly. At this time, the baffle is on one side of the transmission component to prevent waste from leaking out of the side of the transmission component, thereby ensuring that the discharge port at the bottom of the screen box is opened when the crushing bucket is dumped, reducing dust at the discharge port.

[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0040] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0041] In addition, in this application, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0042] The materials generated during the construction process need to be treated accordingly. Concrete waste is generally treated by crushing it first, and then the large pieces of concrete are placed in the crushing equipment with a bucket for crushing. The crushed concrete is screened and finally transported to the corresponding location by conveyor belt.

[0043] In the related art, when pre-processing large pieces of construction waste, it is necessary to first use a breaker to break them, and then replace the bucket to pour the pre-processed waste into the crushing equipment. The replacement requires multiple operations, which causes this method to take a lot of time. When large pieces of waste are buried, the breaker needs to be replaced. Therefore, a construction waste processing device that is easy to switch between a breaker and a shovel head is proposed.

[0044] In order to solve the problems in the related technology to a certain extent, the embodiment of the present application provides a construction waste processing device, in which the adjustment component 200 can change the angles of the crushing bucket 300 and the crushing hammer 400. When encountering large pieces of construction waste, the control adjustment component 200 can quickly switch the crushing hammer 400, and use the crushing hammer 400 to crush the waste. After adjustment again, the crushing bucket 300 is rotated downward to shovel the waste in, thereby improving the crushing efficiency and dumping efficiency of the waste.

[0045] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0046] Combination Figure 1-Figure 5 The embodiment of the present application provides a construction waste treatment device, including a vehicle body 100, a screening component 500 on the top of the vehicle body 100, and a transmission component 600 on the top of the vehicle body 100 close to the bottom of the screening component 500. The screening component 500 screens the crushed waste, mainly separating the iron waste from concrete and soil. The transmission component 600 lifts the separated waste to a certain height and transmits it to a corresponding device, or the waste falls and accumulates.

[0047] The vehicle body 100 includes a vehicle plate 110, and a column 120 is arranged on the top of the vehicle plate 110. The column 120 is provided with four and fixed to the top of the vehicle plate 110 by welding. One side of the column 120 is rotatably connected to the adjustment component 200, and the crushing bucket 300 and the crushing hammer 400 are rotatably connected to the adjustment component 200. The adjustment component 200 includes: a support arm 210 is rotatably connected to one side of the column 120, and a slider 220 is slidably connected to one side of the support arm 210. A stopper 230 for limiting the sliding position of the slider 220 is arranged at one end of the support arm 210; a shaft 270 is rotatably connected to the slider 220, and the outer wall of the shaft 270 is fixedly connected to a connecting seat 1 280, the column 120 is used to support the screening component 500, and can also support the support arm 210. Two support arms 210 are provided, which are respectively arranged on the outside of the two column 120. The inner side of the support arm 210 is provided with a groove near the crushing bucket 300. The opposite sides of the two support arms 210 are provided with grooves, and the grooves are used to limit the sliding position of the slider 220. The stopper 230 is welded to the end position of the support arm 210, and is used to limit the slider 220 from sliding out of the groove. The groove is shown in the attached figure. The two sliders 220 are connected with a shaft body 270 by a bearing. The outer wall of the shaft body 270 is provided with a connecting seat 280, and the two are fixed.

[0048] A moving assembly 700 is disposed on the top of the connecting seat 280 . The moving assembly 700 is used to change the position of the breaker 400 . The rotation of the shaft 270 can change the rotation angles of the breaker bucket 300 and the breaker 400 .

[0049] Specifically, the vehicle plate 110 is moved to the corresponding position manually or by driving, and the positions of the crushing bucket 300 and the crushing hammer 400 are changed by controlling the rotation of the shaft body 270. After the crushing hammer 400 performs preliminary crushing on the construction waste, the positions of the two are changed again by the shaft body 270 so that the crushing bucket 300 is in the lower position. The pre-treated waste can be shoveled into the crushing bucket 300 by moving the vehicle body 100. During the shoveling process, the position of the slider 220 in the groove can be controlled to clean the waste in the area. Finally, after the crushing bucket 300 is filled, the angle of the support arm 210 is controlled to raise the crushing bucket 300 to the top of the screening assembly 500 (see attached Figure 2 ), at this time, by controlling the operation of the crushing bucket 300, the construction waste in the bucket is crushed, and the crushed waste falls into the screening component 500, which screens the waste, and the screened waste is transmitted out by the transmission component 600.

[0050] Specifically, the model of the crushing bucket 300 is jw-23-8, which is common knowledge. It adopts a jaw crushing method to crush the waste, and a crushing chamber is composed of two jaw plates, a movable jaw and a static jaw.

[0051] In some embodiments, a gear 271 is disposed on the outer wall of the shaft 1 270, a gear 271 is fixed to the outer sleeve of the shaft 1 270, a gear box 240 is fixed to the top of the slider 220, a motor 250 is fixed to one side of the gear box 240, the motor 250 is electrically connected to an external power supply, the output shaft of the motor 250 is connected to the gear 1 241, and the gear 1 241 is meshingly connected to the gear 2 271.

[0052] Specifically, the motor 250 drives the gear 1 241, the gear 1 241 drives the gear 2 271 to rotate, and then drives the shaft 1 270 to rotate, so that the connecting seat 1 280 on the shaft 1 270 rotates. At this time, the upper and lower positions of the crushing bucket 300 or the crushing hammer 400 can be changed, so that the two can be quickly switched, which is convenient for dealing with large pieces of waste in the area.

[0053] In some embodiments, a hydraulic cylinder 260 is fixed on the inner side of the support arm 210 and is completely embedded in the groove. The hydraulic cylinder 260 is used to change the position of the slider 220 on the support arm 210. When the hydraulic cylinder 260 is fully retracted, it occupies half of the position of the support arm 210.

[0054] Specifically, by controlling the operation of the hydraulic cylinder 260, the sliding position of the slider 220 on the support arm 210 can be changed, and then the regional position of the crushing bucket 300 or the crushing hammer 400 can be changed, so as to facilitate the processing of construction waste.

[0055] In some embodiments, the moving assembly 700 includes: a bearing seat 710 is symmetrically fixed to the top of the slider 220 by bolts, and the facing surfaces of the two bearing seats 710 are rotatably connected to the screw 720 by bearings; a slide seat 730 is threadedly connected to the outer wall of the screw 720, and the slide seat 730 slides on the top of the connecting seat 280. A motor three 740 for driving the screw 720 is provided on one side of the bearing seat 710, and the motor three 740 is electrically connected to an external power supply.

[0056] Specifically, the moving assembly 700 can change the position of the breaker 400 on the connecting seat 280. When the breaker 400 needs to fine-tune its position when crushing waste, the moving assembly 700 can change the position of the breaker 400 on the Y axis of the connecting seat 280, and the hydraulic cylinder 260 can change the position of the breaker 400 on the X axis of the connecting seat 280, so that the user can crush the waste without having to adjust the position of the vehicle body multiple times.

[0057] The operation of the motor 3 740 drives the screw 720 to rotate, and the screw 720 drives the slide 730 to perform linear motion on the connecting seat 1 280, and the slide 730 changes the position of the breaker 400 on the Y axis of the connecting seat 1 280 (the Y axis is the axis of the connecting seat 1 280). Figure 1 (depending on the viewing angle).

[0058] In some embodiments, one side of the screw rod 720 is connected to the second connecting seat 731 by means of a damping bearing. The damping bearing has a damping feeling when rotating, which is common knowledge. A tube body 732 is provided at the bottom of the second connecting seat 731.

[0059] Specifically, the connecting seat 2 731 is a two-way structure, one of which is connected to an external water source, and the other is connected to the pipe body 732. The pipe body 732 sprays the external water source to reduce dust in the feeding area of ​​the crushing bucket 300, thereby reducing the dust in the area.

[0060] In some embodiments, the rotation angle of the connecting seat 2 731 is 0-360 degrees. The user can rotate the connecting seat 2 731 according to the on-site conditions to reduce dust in different areas. The tube body 732 is an L-shaped structure. This shape makes it easier for the tube body 732 to be attached to the outer wall of the crushing bucket 300, reducing the occupied space. The water outlet end of the tube body 732 has a nozzle, which can atomize the external water source, thereby increasing the dust reduction area. The nozzle is an atomizing nozzle.

[0061] In some embodiments, a motor 121 for driving the support arm 210 to rotate is provided on one side of the column 120. The rotation angle of the support arm 210 can be changed by driving the motor 121. The principle can refer to the rotation of the driving connecting seat 280, both of which rotate through two gears.

[0062] In some embodiments, the screening assembly 500 includes: a feed hopper 510 fixed to the top of the column 120; a buffer column 530 is arranged on the top of the vehicle plate 110, and a screen box 520 is fixedly connected to the buffer column 530. There is no direct connection between the feed hopper 510 and the screen box 520. The screen box 520 is vibrated by a vibration motor, and the screen box 520 can be buffered by four groups of springs on the buffer column 530. Finally, the waste is screened by the screen in the screen box 520. The screen and the vibration motor are not shown in the drawings and are common knowledge. The screen box 520 is located below the feed hopper 510.

[0063] In some embodiments, one side of the column 120 is rotatably connected to the shaft 2 540 , one end of the shaft 2 540 is connected to the support arm 210 , and a baffle 550 is disposed on the outer side wall of the shaft 2 540 .

[0064] Specifically, shaft body 2 540 is rotatably connected to the two column bodies 120 respectively, and a gear cooperating with motor 121 is provided on shaft body 2 540 inside column body 120. When the support arm 210 rotates, shaft body 2 540 also drives baffle 550 to rotate, thereby changing the bottom material discharge situation of screen box 520 and reducing the leakage of waste from one side of transmission component 600.

[0065] In some embodiments, the rotation angle of the support arm 210 is 0-200 degrees. When the support arm 210 rotates, it can drive the second shaft 540 to rotate, and then drive the baffle 550 to rotate to change the bottom discharge condition of the screen box 520.

[0066] Specifically, while the support arm 210 is rotating, it can drive the baffle 550 at the bottom of the screen box 520 to open the discharge port at the bottom of the screen box 520, and then when the support arm 210 rotates the crushing bucket 300 to the top of the screen box 520, the baffle 550 is also completely opened accordingly. At this time, the baffle 550 is on one side of the transmission component 600, blocking the waste from leaking out of the side of the transmission component 600, thereby ensuring that the discharge port at the bottom of the screen box 520 is opened when the crushing bucket 300 is dumped, reducing dust at the discharge port.

[0067] Working principle: when in use, firstly, the vehicle plate 110 is moved to the corresponding position manually or by driving, and the motor 250 drives the gear 1 241, and the gear 1 241 drives the gear 271 to rotate, thereby driving the shaft 1 270 to rotate, so that the connecting seat 1 280 on the shaft 1 270 rotates, and at this time, the upper and lower positions of the crushing bucket 300 or the crushing hammer 400 can be changed. After the crushing hammer 400 performs preliminary crushing on the construction waste, the shaft 1 270 changes the positions of the two again, so that the crushing bucket 300 is at the bottom. The pre-processed waste can be shoveled into the crushing bucket 300 by moving the vehicle body 100, or the hydraulic cylinder 260 can be controlled to change the sliding position of the slider 220 on the support arm 210, thereby changing the regional position of the crushing bucket 300 or the crushing hammer 400, so as to facilitate the processing of the construction waste. Secondly, after the crushing bucket 300 is filled, the angle of the support arm 210 is controlled by controlling the motor 121 to raise the crushing bucket 300 to the top of the screening assembly 500 (see attached Figure 2), at this time, the construction waste in the bucket is crushed by controlling the operation of the crushing bucket 300, and the crushed waste falls into the screening component 500, and the screen box 520 is vibrated by a vibration motor, and the screen box 520 can be buffered by four groups of springs on the buffer column 530, and finally the waste is screened by the screen in the screen box 520. The screen and the vibration motor are not shown in the accompanying drawings and are common knowledge. The screen box 520 is located below the feed hopper 510, and finally the screened waste is transmitted out by the transmission component 600.
