Description

Technical Field

[0001] This invention relates to the field of road construction equipment technology, and more specifically, to a device and method for laying base stabilized soil. Background Technology

[0002] Base course stabilized soil is a material mainly made by mixing lime, cement, fly ash, and other binders with soil, gravel, or other aggregates. It is primarily used for paving road base courses. For the paving of base course stabilized soil in situations such as pedestrian walkways, auxiliary roads, road reconstruction, and road expansion, large machinery such as pavers is difficult to access the construction site, so it mostly needs to be done manually, resulting in a low level of mechanization. Summary of the Invention

[0003] This invention provides a base-stabilized soil laying device that can overcome some or more defects of the prior art.

[0004] The base stabilized soil laying device according to the present invention includes: a device body, the device body including a skeleton assembly, the skeleton assembly including a support frame, a support plate provided at the top of the support frame; a drive roller and a rolling roller rotatably provided at both ends of the bottom of the support frame in the length direction, the drive roller and the rolling roller being cylindrical and extending in the width direction of the support frame; a hopper provided at the top of the support plate, the hopper forming a material cavity for storing base stabilized soil, a discharge roller that rolls with the material cavity at the bottom of the material cavity; a discharge port provided at the support plate corresponding to the discharge roller, the discharge port being located between the drive roller and the rolling roller; the discharge port extending in the width direction of the support frame, neither end of the discharge port in the width direction of the support frame exceeding the corresponding end of the rolling roller in the width direction of the support frame.

[0005] In this invention, the base stabilized soil is stored in a silo, and the base stabilized soil is discharged by rotating the discharge roller. The drive roller is used to drive the discharge roller to rotate, and the rolling roller is used to roll the base stabilized soil that falls on the road surface to be paved, so as to form a compact and stable road base layer, thus improving the paving efficiency of the base stabilized soil.

[0006] Preferably, the hopper includes a detachable feed housing and a discharge housing. The feed housing has a first semi-circular groove at both ends along the length direction, and the discharge housing has a corresponding second semi-circular groove. The first and second semi-circular grooves are used to cooperate with the discharge roller.

[0007] In this invention, by setting a first semicircular groove and a second semicircular groove, which are preferably matched with the discharge roller, the rolling cooperation between the discharge roller and the first semicircular groove and the second semicircular groove is realized, thus achieving better uniform discharge of the discharge roller.

[0008] Preferably, the discharge roller includes a discharge roller body, and two feeding hoppers are formed along the length direction of the discharge roller body. The first semicircular groove forms a feeding port along the length direction, and the second semicircular groove forms a discharging port along the length direction.

[0009] In this invention, the take-up and release bucket is used to convey the base stabilized soil in the discharge roller. When the take-up and release bucket is facing the hopper, the base stabilized soil falls into the take-up and release bucket from the feed port; when the take-up and release bucket is facing the discharge port, the base stabilized soil falls from the discharge port to the discharge port and falls from the discharge port to the road surface to be paved.

[0010] Preferably, a first mating shaft is formed at one end of the discharge roller, a first bearing seat is provided at the support plate, a first bearing is provided at the first bearing seat, and a first journal is formed at the first mating shaft, which is used to rotate with the first bearing; a second mating shaft is formed at the other end of the discharge roller, a second bearing seat is provided at the support plate, a second bearing is provided at the second bearing seat, and a second journal is formed at the second mating shaft, which is used to rotate with the second bearing.

[0011] In this invention, the first bearing housing and the first journal are used to cooperate with the first bearing, and the second bearing housing and the second journal are used to cooperate with the second bearing. Therefore, the discharge roller can rotate better, and the first bearing housing and the second bearing housing can better support the discharge roller, thereby reducing the friction between the discharge roller and the first semicircular groove and the second semicircular groove, thus improving the operating stability of the discharge roller.

[0012] Preferably, a control component is provided at the support plate. The control component includes a detachably fitted upper shell and a lower shell, which together form a mounting cavity. A first fitting mechanism and a second fitting mechanism are rotatably provided within the mounting cavity. The second fitting mechanism is used to keep the first fitting mechanism in a first state when the corresponding discharge roller is in the discharge state, and to keep the first fitting mechanism in a second state when the corresponding discharge roller is in the non-discharge state. When the first fitting mechanism is in the first state, the discharge roller rotates to discharge material, and when the first fitting mechanism is in the second state, the discharge roller remains stationary.

[0013] In this invention, the control component is used to control the power transmission between the drive roller and the discharge roller, and the first and second mating mechanisms are used to control the rotation and stopping of the discharge roller.

[0014] Preferably, the first mating mechanism includes a first mating component and a second mating component; the first mating component includes a first rotating member, which includes a first mating disk, and a third mating shaft is formed at the center of one end of the first mating disk; the second mating component includes a first housing and a second housing that can be detachably mated, a positioning shaft is formed at the center of the first housing, a positioning hole is formed at the first mating disk, the positioning shaft is used to mate with the positioning hole, the second mating disk is slidably disposed inside the first housing, a plurality of circumferentially arrayed transmission pins are formed at one end of the second mating disk, the ends of the transmission pins are hemispherical, a transmission pin hole is provided at the first mating disk, a first spring mounting groove is formed at the transmission pin of the second mating disk, a second spring mounting groove is provided at the first housing, a first spring is sleeved at the transmission pin, the first spring is used to maintain the tendency of the second mating disk away from the first mating mechanism; the second housing includes an end cover and a fourth mating shaft formed at the end cover.

[0015] In this invention, the first mating component is used to cooperate with the second mating component to realize the synchronous rotation and separation of the first mating component and the second mating component. When the first mating mechanism is in the first state, the first mating component and the second mating component rotate synchronously. When the first mating mechanism is in the second state, the first mating component and the second mating component separate. Therefore, the power transmission control between the drive roller and the discharge roller can be better realized.

[0016] Preferably, the second mating mechanism includes a pressing shaft, a fourth mating shaft forming a first mating channel along the axial direction, abutting portion forming abutting portion that slides with the first mating channel at one end of the pressing shaft, a third spring mounting groove provided at the center of the pressing shaft along its length, and a second spring provided at the third spring mounting groove, the second spring being used to maintain the pressing shaft against the second mating disc; a control shaft provided at the other end of the pressing shaft, the control shaft including a control shaft body, a second mating channel provided along the length of the control shaft body, the second mating channel being used for sliding with the pressing shaft; a first threaded portion forming at one end of the control shaft body, a corresponding second threaded portion provided at the first mating channel, the first threaded portion and the second threaded portion being threadedly engaged; and a mating handle forming at the other end of the control shaft body.

[0017] In this invention, the control shaft body can axially press the second mating disk along the first mating channel via a thread, thus enabling the second mating disk to mate with the first mating disk. The control shaft is used to control the second spring. When the control shaft moves along the second mating disk, the control shaft applies prestress to the second spring. At this time, the second spring is under force. When the transmission pin shaft and the transmission pin hole are coaxial, the transmission pin shaft enters the transmission pin hole, and the first mating mechanism is in the first state. When the control shaft moves away from the second mating disk, the control shaft does not apply stress to the second spring. Therefore, under the action of the first spring, the transmission pin shaft leaves the transmission pin hole, and the first mating mechanism is in the second state.

[0018] Preferably, four support seats are symmetrically arranged on both sides of the support frame in the width direction. The four support seats are used to install the drive roller and the rolling roller. Mounting holes are formed at the support seats. Two first mounting shafts are formed at both ends of the drive roller along the length direction, corresponding to the mounting holes. Two second mounting shafts are formed at both ends of the rolling roller along the length direction, corresponding to the mounting holes. A first pulley is formed at the first mounting shaft on the same side as the control component, and a second pulley is formed at the second housing. A first belt is provided between the first pulley and the second pulley. A third pulley is formed at the first housing, and a fourth pulley is formed at the second mounting shaft. A second belt is provided between the third pulley and the fourth pulley.

[0019] In this invention, the first pulley, the second pulley, and the first belt are used to realize the transmission between the drive roller and the second mating assembly, and the third pulley, the fourth pulley, and the second belt are used to realize the transmission between the first mating assembly and the discharge roller.

[0020] Preferably, the surface of the drive roller is formed with raised patterns.

[0021] In this invention, the raised pattern can increase the friction between the drive roller and the ground to be paved, thus enabling the drive roller to rotate more effectively.

[0022] The present invention also provides a method for laying base stabilized soil, which can be applied to the above-mentioned base stabilized soil laying device, comprising the following steps: Step S1: Fill the silo with base stabilized soil; Step S2: Control the first cooperating mechanism to the second state and pull the paving device to the road surface to be paved; Step S3: Control the first coordinating mechanism to be in the first state, and the traction laying device lays the base stabilized soil along the road surface.

[0023] This invention enables the efficient filling, transportation, and laying of base stabilized soil. Attached Figure Description

Detailed Implementation

[0025] To further understand the content of this invention, the invention will be described in detail with reference to the embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the invention. Example 1

[0026] This embodiment provides a base stabilized soil laying device, which includes a device body 100, a frame assembly 110, a support frame 111, and a support plate 112 at the top of the support frame 111. At the bottom of the support frame 111, a drive roller 113 and a rolling roller 114 are rotatably provided at both ends along the length direction. Both the drive roller 113 and the rolling roller 114 are cylindrical and extend along the width direction of the support frame 111. A hopper 120 is provided at the top of the support plate 112. A material cavity 121 is formed inside the support frame 120. The material cavity 121 is used to store the base stabilized soil. The bottom of the material cavity 121 is provided with a discharge roller 440 that rolls with the material cavity 121. A discharge port 417 is provided at the support plate 112 corresponding to the discharge roller 440. The discharge port 417 is located between the drive roller 113 and the rolling roller 114. The discharge port 417 extends in the width direction of the support frame 111. Neither end of the discharge port 417 in the width direction of the support frame 111 exceeds the corresponding end of the rolling roller 114 in the width direction of the support frame 111.

[0027] In this embodiment, the base stabilized soil is stored in the silo 120. The base stabilized soil is discharged by rotating the discharge roller 440. The drive roller 113 is used to drive the discharge roller 440 to rotate. The rolling roller 114 is used to roll the base stabilized soil that falls on the road surface to be paved, so that the base stabilized soil on the road surface to be paved forms a compact and stable road base, thus improving the paving efficiency of the base stabilized soil.

[0028] When using this device, construction workers transport the base stabilized soil to the material chamber 121 using a dump truck or feeding equipment. The device body 100 is then towed by the towing unit located at the front of the device body 100. The towing device body 100 moves forward along the road to be paved, and the discharge roller 440 rotates as it moves forward along the paved road, transporting the base stabilized soil from the material bin 120 to the discharge port 417. The base stabilized soil then falls to the ground from the discharge port 417.

[0029] The drive roller 113 is located at the front of the main body 100 in the forward direction, and the rolling roller 114 is located at the rear of the main body 100 in the forward direction. Therefore, when the material drop port 417 is located between the drive roller 113 and the rolling roller 114, the base stabilized soil falling on the ground to be paved can be rolled by the rolling roller 114. The two ends of the material drop port 417 in the width direction of the support frame 111 do not exceed the corresponding ends of the rolling roller 114 in the width direction of the support frame 111. Therefore, the base stabilized soil falling on the road surface to be paved can be rolled evenly by the rolling roller 114.

[0030] Understandably, the trailer can be a tow hook or a tow hole, and towing can be done by a wheeled vehicle or by manpower.

[0031] The hopper 120 includes a detachable feed housing 322 and a discharge housing 323. The feed housing 322 has a first semi-circular groove 622b at both ends along the length direction, and the discharge housing 323 has a corresponding second semi-circular groove 723b. The first semi-circular groove 622b and the second semi-circular groove 723b are used to cooperate with the discharge roller 440.

[0032] In this embodiment, by setting the first semicircular groove 622b and the second semicircular groove 723b, which are preferably matched with the discharge roller 440, the rolling cooperation between the discharge roller 440 and the first semicircular groove 622b and the second semicircular groove 723b can be achieved, thus enabling the uniform discharge of the discharge roller 440.

[0033] The first housing 1336a and the second housing 1336b are fitted together by bolts, and the first semicircular groove 622b and the second semicircular groove 723b are fitted together to form a cylindrical surface for fitting with the discharge roller 440.

[0034] The discharge roller 440 includes a discharge roller 440 body, and two feeding hoppers 542 are formed along the length direction of the discharge roller 440 body. The first semi-circular groove 622b forms a feed inlet 622a along the length direction, and the second semi-circular groove 723b forms a discharge outlet 723a along the length direction.

[0035] When using this device, the take-up bucket 542 is used to convey the base stabilized soil in the discharge roller 440. When the take-up bucket 542 is facing the hopper 120, the base stabilized soil falls into the take-up bucket 542 from the feed port 622a. When the take-up bucket 542 is facing the discharge port 417, the base stabilized soil falls from the discharge port 723a to the discharge port 417 and falls from the discharge port 417 to the road surface to be paved.

[0036] It is understandable that the widths of the feeding hopper 542, the feed inlet 622a, and the discharge outlet 723a are the same.

[0037] One end of the discharge roller 440 forms a first mating shaft 443, a first bearing seat 444 is provided at the support plate 112, a first bearing 445 is provided at the first bearing seat 444, and a first journal 443a is formed at the first mating shaft 443. The first journal 443a is used to rotate with the first bearing 445. The other end of the discharge roller 440 forms a second mating shaft 446, a second bearing seat 447 is provided at the support plate 112, a second bearing 448 is provided at the second bearing seat 447, and a second journal 446a is formed at the second mating shaft 446. The second journal 446a is used to rotate with the second bearing 448.

[0038] As described above, the first bearing housing 444 and the first journal 443a are used to cooperate with the first bearing 445, and the second bearing housing 448 and the second journal 446a are used to cooperate with the second bearing 448. Therefore, the discharge roller 440 can rotate better, and the first bearing housing 444 and the second bearing housing 448 can better support the discharge roller 440, better reduce the friction between the discharge roller 440 and the first semicircular groove 622b and the second semicircular groove 723b, thereby improving the operating stability of the discharge roller 440.

[0039] The first bearing housing 444 and the second bearing housing 448 447 can be detachably coupled with the support plate 112.

[0040] A control component 230 is provided at the support plate 112. The control component 230 includes a detachably fitted upper housing 231 and a lower housing 232. The upper housing 231 and the lower housing 232 together form a mounting cavity. A first fitting mechanism 1033 and a second fitting mechanism 1034 are rotatably provided in the mounting cavity. The second fitting mechanism 1034 is used to keep the first fitting mechanism 1033 in a first state when the corresponding discharge roller 440 is in the discharge state, and to keep the first fitting mechanism 1033 in a second state when the corresponding discharge roller 440 is in the non-discharge state. When the first fitting mechanism 1033 is in the first state, the discharge roller 440 rotates to discharge material. When the first fitting mechanism 1033 is in the second state, the discharge roller 440 remains stationary.

[0041] Through the above scheme, the control component 230 is used to control the power transmission between the drive roller 113 and the discharge roller 440, and the first cooperating mechanism 1033 and the second cooperating mechanism 1034 are used to control the rotation and stop of the discharge roller 440.

[0042] In use, the first cooperating mechanism 1033 and the second cooperating mechanism 1034 are used to control the operating state of the discharge roller 440. When in the first state, the discharge roller 440 can rotate to discharge material; when in the second state, the discharge roller 440 is stationary.

[0043] Understandably, when construction workers add base stabilized soil to the material bin 120 and the main body of the traction device 100 to the road surface to be paved, the first coordinating mechanism 1033 needs to be in the second state. At this time, the discharge roller 440 is stationary, and the base stabilized soil will not fall to the ground when the main body of the traction device 100 moves. When the main body of the device 100 is pulled to the road surface to be paved for base stabilized soil paving, the first coordinating mechanism 1033 needs to be in the first state. At this time, the discharge roller 440 rotates, and the base stabilized soil can fall onto the road surface to be paved.

[0044] The first mating mechanism 1033 includes a first mating component 1135 and a second mating component 1136. The first mating component 1135 includes a first rotating member 1335a, which includes a first mating disk 1335b. A third mating shaft 1335c is formed at the center of one end of the first mating disk 1335b. The second mating component 1136 includes a detachably mating first housing 1336a and a second housing 1336b. A positioning shaft 1336c is formed at the center of the first housing 1336a. A positioning hole 1336d is formed at the first mating disk 1335b. The positioning shaft 1336c is used to mate with the positioning hole 1336d. The second mating disk 1135a is slidably disposed inside the first housing 1336a. 6e, a plurality of circumferentially arrayed transmission pins 1436f are formed at one end of the second mating disc 1336e. The end of the transmission pin 1436f is hemispherical. A corresponding transmission pin hole is provided at the first mating disc 1335b. A first spring mounting groove 1436g is formed at the transmission pin 1436f on the second mating disc 1336e. A corresponding second spring mounting groove 1436h is provided on the first housing 1336a. A first spring 1436i is sleeved at the transmission pin 1436f. The first spring 1436i is used to keep the second mating disc 1336e away from the first mating mechanism 1033. The second housing 1336b includes an end cap 1336j and a fourth mating shaft 1336k formed at the end cap 1336j.

[0045] Through the above scheme, the first mating component 1135 is used to cooperate with the second mating component to realize the synchronous rotation and separation of the first mating component 1135 and the second mating component 1136. When the first mating mechanism 1033 is in the first state, the first mating component 1135 and the second mating component 1136 rotate synchronously. When the first mating mechanism 1033 is in the second state, the first mating component 1135 and the second mating component 1136 separate. Therefore, the power transmission control between the drive roller 113 and the discharge roller 440 can be better realized.

[0046] It is understandable that when the first mating mechanism 1033 is in the first state, the transmission pin 1436f is engaged with the transmission pin hole, and the transmission pin 1436f is inserted into the transmission pin hole. At this time, when the second mating component 1136 rotates, it can drive the first mating component 1135 to rotate. When the first mating mechanism 1033 is in the second state, the transmission pin 1436f is not engaged with the transmission pin hole. Therefore, when the second mating component 1136 rotates, it will not drive the first mating component 1135 to rotate.

[0047] The second mating mechanism 1034 includes a pressing shaft 1334a, a fourth mating shaft 1336k forming a first mating channel 1334b along the axial direction, abutting portion 1334c forming at one end of the pressing shaft 1334a, the abutting portion 1334c slidingly engaging with the first mating channel 1334b, a third spring mounting groove 1534d provided at the center of the pressing shaft 1334a along its length, and a second spring 1534e provided at the third spring mounting groove 1534d, the second spring 1534e being used to maintain the tendency of the pressing shaft 1334a to abut against the second mating disc 1336e; the pressing shaft 1334a... At the other end of a, a control shaft 1334f is provided. The control shaft 1334f includes a control shaft body 1334g. The control shaft body 1334g has a second mating channel 1334h along its length, which is used for sliding mating with the extrusion shaft 1334a. A first threaded portion 1534i is formed at one end of the control shaft body 1334g, and a second threaded portion 1534j is correspondingly provided at the first mating channel 1334b. The first threaded portion 1534i and the second threaded portion 1534j are threadedly mated. A mating handle 1334k is formed at the other end of the control shaft body 1334g.

[0048] In this embodiment, the control shaft body 1334g can axially press the second mating disk 1336e along the first mating channel 1334b via threads, thus enabling the second mating disk 1336e to mate with the first mating disk 1335b. The control shaft 1334f is used to control the second spring 1534e. When the control shaft 1334f moves toward the second mating disk 1336e, it applies prestress to the second spring 1534e. At this time, the second spring 1534e is under force. When the transmission pin 1436f is coaxial with the transmission pin hole, the transmission pin 1436f enters the transmission pin hole. At this time, the first mating mechanism 1033 is in the first state. When the control shaft 1334f moves away from the second mating disk 1336e, it does not apply stress to the second spring 1534e. Therefore, under the action of the first spring 1436i, the transmission pin 1436f leaves the transmission pin hole. At this time, the first mating mechanism 1033 is in the second state.

[0049] The spring constant of the second spring 1534e is greater than that of the first spring 1436i.

[0050] The support frame 111 has four symmetrical support seats 315 on both sides of its width direction. The four support seats 315 are used to install the drive roller 113 and the rolling roller 114. The support seats 315 form mounting holes 316. The drive roller 113 has two first mounting shafts 813a at both ends of its length direction that correspond to the mounting holes 316. The rolling roller 114 has two second mounting shafts 914a at both ends of its length direction that correspond to the mounting holes 316. A first pulley 251 is formed at the first mounting shaft 813a on the same side as the control component 230. A second pulley 252 is formed at the second housing 1336b. A first belt 253 is provided between the first pulley 251 and the second pulley 252 to cooperate with them. A third pulley 254 is formed at the first housing 1336a. A fourth pulley 255 is formed at the second mating shaft 446. A second belt 256 is provided between the third pulley 254 and the fourth pulley 255 to cooperate with them.

[0051] In this embodiment, the first pulley 251, the second pulley 252 and the first belt 253 are used to realize the transmission between the drive roller 113 and the second mating assembly 1136, and the third pulley 254, the fourth pulley 255 and the second belt 256 are used to realize the transmission between the first mating assembly 1135 and the discharge roller 440.

[0052] In use, when the drive roller 113 rotates, the power is transmitted to the second mating assembly 1136 through the first belt 253. When the first mating mechanism 1033 is in the first state, the second mating assembly 1136 rotates synchronously with the first mating assembly 1135, so the second mating assembly 1136 can transmit power to the first mating assembly 1135. When the first mating assembly 1135 rotates, the power is transmitted to the discharge roller 440 through the second belt 256, so the rotation of the discharge roller 440 can be better realized.

[0053] The surface of the drive roller 113 is formed with raised patterns 813b.

[0054] As described above, the raised pattern 813b can increase the friction between the drive roller 113 and the ground to be paved, thus enabling the drive roller 113 to rotate more effectively. Example 2

[0056] In this embodiment, the above steps can effectively achieve the filling, transportation, and laying of base stabilized soil.
