- the linear velocity since the linear velocity is equal to the angular velocity multiplied by the radius, and the radius of the conveying roller 5 and the radius of the traveling wheel 2 have been determined, so that the thickness of the lime powder obtained
- the height of the thickness baffle plate 7 is adjusted first. If it is necessary to adjust the thickness of the lime powder, the height of the thickness baffle plate 7 is adjusted first, so that the worker pulls the frame 1 The force does not change much, and if the speed ratio is not adjusted by adjusting the thickness of the baffle plate 7, the rotation speed of the worker acting on the conveying roller 5 at the same walking speed is increased, and it is necessary to increase the pulling force of the worker and increase the labor of the worker.
- the strength is therefore in the design range. If the lime powder is increased, the height of the lime powder baffle is preferentially adjusted, which saves the worker's strength. Of course, the height of the lime powder retaining plate cannot be increased without limit. At least it is lower than the height of the discharge port of the hopper 3. Therefore, if the height of the baffle plate is adjusted to the maximum limit, if the thickness of the lime powder is to be increased, the speed ratio can be adjusted.
- the lime powder is provided with a width baffle plate 8 and a thickness baffle plate 7 to ensure uniformity of lime powder laying. Of course, in addition to adjusting the thickness of the lime powder by using the dial 16, it is also possible to adjust the power shaft by measuring the thickness of the lime powder after laying.

以下结合附图1-15对本发明的具体实施方式作进一步的详细说明。
实施例1,一种多用途公路施工装置,包括机架1,所述机架1下端呈矩形布置有四个行走轮2,所述机架1上端固定有料斗3,该料斗3可以为上大下小的梯形料斗,所述料斗3下端开有出料口4,所述机架1左右两侧转动连接有输送辊5,两输送辊5之间套连有间隔置于出料口下方的输送带6,其特征在于,所述输送带6的左侧上部设有高度可调的厚度挡料板7,所述料斗3和厚度挡料板7之间前后侧分别设有宽度挡料板8,该宽度挡料板8与厚度挡料板7之间滑动配合,该宽度挡料板8与其下端的输送带6之间滑动配合,还包括其中一个输送辊5(图1中所示为右侧的输送辊)和行走轮2(图1所示为右侧后部的行走轮5)之间连接的速度比调节装置,该速度比调节装置可以对行走轮2和输送辊5的速度比进行无极调节,该速度比调节装置伸出一速度比调节轴9,所述厚度挡料板7连接有厚度调节驱动装置,该厚度调节驱动装置伸出一与速度比调节轴9平行的厚度调节轴10,所述厚度调节轴10套固有第九齿轮11,所述速度比调节轴9前端套固有第十齿轮12,还包括置于第九齿轮11和第十齿轮12之间的转动连接在机架1上的动力轴13,所述动力轴13上固定有速度比扇形齿轮14和厚度扇形齿轮15,所述动力轴13前端转动连接有固定在机架1上的刻度盘16,所述动力轴13前端伸出刻度盘16且固定有与刻度盘配合的指针17,朝着厚度挡料板提升的方向旋转动力轴13,此时厚度扇形齿轮15与第九齿轮11啮合,当厚度扇形齿轮15与第九齿轮11脱离啮合时速度比扇形齿轮14与第十齿轮12啮合。在动力轴13上加有角度限位结构,该角度限位结构使得动力轴13只能在小于360的角度内旋转,且在该范围内旋转时厚度扇形齿轮15与速度比扇形齿轮14分别交替啮合与其对应的齿轮且不会同时脱离与其相配合的齿轮。具体的,该角度限位结构为,在动力轴13上固定一个挡杆18,围绕动力轴13圆周方向间隔设置两个固定在机架1上的限位挡块19,该挡杆18在两个限位挡块19之间旋转,当挡杆18接触到第一个限位挡块19时,此时厚度扇形齿轮15与第九齿轮11啮合,且此时厚度挡料板7到输送带6的距离最近,当动力轴13转动时,动力轴13带动厚度扇形齿轮15和速度比扇形齿轮14旋转,此时厚度扇形齿轮15带动第九齿轮11转动,第九齿轮11带动厚度挡料板7向上移动,当厚度扇形齿轮15脱离第九齿轮11时速度比扇形齿轮14与第十齿轮12啮合,此时厚度挡料板7停止在当下位置(此时厚度挡料板7处于最高位置),而第十齿轮12驱动速度比调节装置进行输送辊5和行走轮2之间的速度比的调节(此时是将输送辊和行走轮之间的速度比调大),当挡杆18接触到第二个限位挡块19时,此时动力轴13不能继续旋转,此时的速度比扇形齿轮14仍然处于与第十齿轮12啮合的状态,此时的石灰粉的摊铺厚度调节到最大。当需要调小石灰粉铺设到公路上的厚度时,反向旋转动力轴13,此时速度比扇形齿轮14与第十齿轮12啮合,驱动速度比调节装置将输送辊5与行走轮2的速度比条小,当速度比扇形齿轮14脱离第十齿轮12时,此时厚度扇形齿轮15啮合在第九齿轮11上,由第九齿轮11带动厚度挡料板7向着输送带6的方向移动,来降低输送带6输出的石灰粉的厚度,当挡杆18接触到第一个限位挡块19时,此时动力轴13不能朝着该方向继续旋转,此时的厚度扇形齿轮15与第九齿轮11仍然保持啮合,此时的厚度挡料板7处于最低位置。
所述指针17前方的动力轴13上装有手摇柄20。手摇柄方便操作者摇动动力轴13
该速度比扇形齿轮14和厚度扇形齿轮15之间为前后相叠布置或者前后间隔设置。
还包括连接在机架1左端的导料壳67,所述导料壳67上端具有一置于输送带6左端下方的接料口68,所述导料壳67还具有置于其下部的与接料口68相连通的下料口69。该接料口68和下料口69之间连通有物料通道70,该物料通道70上半部可以为朝着接料口向外张开,该物料通道70下半部可以为前后长度不变,该物料通道70上半部相接接料口,该物料通道70下半部相接下料口69,该下料口69的宽度可以等于两宽度挡料板8之间的宽度。这样设置使得接料口68处纵向宽度大于石灰粉输入的宽度,而石灰粉到下料口69输出的宽度还是等于两宽度挡料板8之间的宽度。当然该物料通道70也可以是整体是个直通槽。该输送带6左下方为该输送带8的出料处。所述导料壳67呈下料口69朝着远离机架1的方向倾斜放置。所述下料口69呈水平状。
实施例2,在实施例1的基础上,所述速度比调节装置包括左右水平设置且相互配合的第一无级变速轮21和第二无级变速轮22,所述无级变速轮包括相对的第一锥形轮23和第二锥形轮24,左侧的第一锥形轮23外端面同轴固定连接有活动轴62,所述活动轴62转动连接有第一移动盘25,所述活动轴62的后端伸出第一移动盘25轴向滑动且同轴连接有第一驱动轴26,第一驱动轴26转动连接在机架1上,左侧的第二锥形轮24转动设置在机架1上,右侧的第二锥形轮24外端面同轴转动连接有第二移动盘27,右侧的第一锥形轮23转动设置在机架1上,还包括设置在无级变速轮左右两侧的转动连接在机架1上的导向杆28,所述第一移动盘25和第二移动盘27的两侧分别螺纹配合在与其相对应的导向杆28上,所述导向杆28经第一传动机构连接在速度比调节轴9上,右侧后部的行走轮2经皮带传动连接在第一驱动轴26上,右侧的第一锥形轮23同轴连接有第一齿轮29,右侧的输送辊5同轴连接有啮合在第一齿轮29上的第二齿轮30,所述第一无极变速轮21与第二无极变速轮22之间套连有锥形带31。该锥形带31的两斜面分别于第一锥形轮23和第二锥形轮24相配合,第一锥形轮23和第二锥形轮24上可以圆周均布有多个沿着其斜面延伸的第一啮合齿,锥形带31的两斜面上设有与第一啮合齿相啮合的第二啮合齿,将第一锥形轮和第二锥形轮设置为齿带轮,将锥形带设置成齿带,使得两者配合的时候不会打滑,保证了传动的稳固性。该处的皮带传动包括套固在第一驱动轴上的第二皮带轮和同轴连接在右侧后部行走轮上的第三皮带轮,第二皮带轮和第三皮带轮之间经第二皮带连接在一起即可。该速度比调节装置在使用时,行走轮2经过皮带传动连接在第一驱动轴26上,第一驱动轴带动第一无级变速轮转动,第一无极变速轮21转动经锥形带31带动第二无级变速轮22转动,第二无极变速22经过第一齿轮29和第二齿轮30带动右侧的输送辊转动,输送辊带动输送带对石灰粉进行输送。由于左侧第一锥形轮23和第二锥形轮24相对设置,其把锥形带挤压在两者之间,因此当左侧的第一锥形轮23被第一驱动轴26驱动时也带动第二锥形轮24转动,左侧的两个锥形轮的转动经锥形带31带动右侧两的锥形轮转动。当需要无极调节输送辊和行走轮的速度比时,旋转动力轴,经动力轴经第一传动机构驱动导向杆旋转,由于导向杆与第一移动盘25和第二移动盘27螺纹配合,因此当导向杆转动时,带动第一移动盘25和第二移动盘27同时向前或向后移动,第一移动盘25带动左侧的第一锥形轮向前或向后移动,第二移动盘27带动右侧的第二锥形轮24向前或向后移动,当左侧的第一锥形轮23和右侧的第二锥形轮24同时向前移动时(朝着刻度盘16的方向移动),输送辊5和行走轮2的速度比减小,公路上的石灰粉变薄,当左侧的第一锥形轮23和右侧的第二锥形轮24同时向后移动时,输送辊和5行走轮2的速度比增大,公路上的石灰粉变厚,使用螺纹配合来调节第一无级变速轮21和第二无级变速轮22的作用直径比,使得其比例无极调速,且螺纹具有调整精确实时自锁的优点。使用该无极调速,可以任意调节可调范围内的速度比,也就是可以任意调节可调范围内的公路上铺设的石灰粉的厚度。该第一驱动轴26面朝活动轴62的端部开有轴向的活动孔64,该活动孔64径向对称的两端的第一驱动轴26内开有与该活动孔64相接的键槽65,此处的两个键槽65朝着活动轴62的端部开放,在活动轴62上径向对称固定有两个与键槽65对应的滑键66,活动轴62轴向滑动配合在活动孔64内,两个滑键66分别轴向滑动配合在两个键槽65内,这样就使得活动轴62可以相对第一驱动轴26轴向移动,且第一驱动轴26转动时可以带动活动轴62转动,进而带动左侧的第一锥形轮23转动。
实施例3,在实施例2的基础上,所述导向杆28前端啮合有第三齿轮32,配合在同一移动盘上的两个导向杆28上的两个第三齿轮32之间啮合有第四齿轮33,所述第四齿轮33同轴连接有第五齿轮34,两第五齿轮34之间啮合有第六齿轮35,所述第六齿轮35同轴连接有转动安装在机架1上的速度比调节轴9,构成导向杆28经第一传动机构连接在速度比调节轴9上的结构。
实施例4,在实施例1的基础上,所述厚度挡料板7前后端的机架1上转动连接有竖向的升降螺杆36,所述厚度挡料板7前后端分别固定有旋拧在升降螺杆36上的升降螺母37,升降螺杆36上端套固有第一锥齿轮38,两升降螺杆36之间设有转动连接在机架1上的传动轴39,所述传动轴39两端套固有分别于其相对应的第一锥齿轮38啮合的第二锥齿轮40,所述传动轴39前端向前越过前端的第一锥齿轮38,所述传动轴39前端经皮带传动连接到置于速度比调节轴9一侧的厚度调节轴10,构成厚度调节装置。或者在传动轴39前方的机架1上转动连接一个第四连杆41,在第四连杆41的后端套固一个第三锥齿轮42,该第三锥齿轮42啮合在前端的升降螺杆37上的第一锥齿轮38上,第四连杆41前端向前伸出机架1且经皮带传动连接到转动连接在机架1上的厚度调节轴10上即可。该升降螺母37在前后侧的厚度挡料板7上分别均设有两个,同一侧的两个升降螺母37上下间隔固定在厚度挡料板7上。该厚度调节装置在使用时,转动动力轴,动力轴13经过厚度扇形齿轮15带动第九齿轮11转动,第九齿轮11带动厚度调节轴10转动,厚度调节轴带动10经皮带传动带动传动轴39转动,传动轴39经第二锥齿轮40和第一锥齿轮38的啮合带动升降螺杆36转动,由于前后端的升降螺母37固定在厚度挡料板7上,因此升降螺杆36的转动经过升降螺母37带动厚度挡料板7的上下移动。
实施例5,在实施例1的基础上,所述宽度挡料板8包括一连接在料斗3上的向内倾斜的第一板801和与第一板801一体连接的横向的第二板802构成,第二板802与厚度挡料板7竖向滑动配合。第一板801和第二板802底壁均贴合有第一橡胶层,该输送带6为表面光滑的皮带,可以为PVC输送带,输送带6上表面与橡胶层滑动配合。在第一板801的面朝厚度挡料板7的侧端上贴合有第二橡胶层,该第二橡胶层压在厚度挡料板7上,而厚度挡料板7的面朝料斗3的侧面可以为光面,这样第二橡胶层与厚度挡料板7之间就构成了滑动配合。在输送带6的上层下侧上可以设置支撑输送带6的支撑台,该支撑台表面呈光滑状。第一橡胶层与输送带6的配合可以防止石灰粉从此处漏出,而第二橡胶层和厚度挡料板7的配合可以防止石灰粉从此处漏出。这两处不仅滑动配合且起到了密封石灰粉的作用。
实施例6,在实施例1的基础上,所述料斗3为上大下小的锥形料斗,所述料斗3的下侧前后侧面之间转动连接有拨料轴43,所述拨料轴43上均布有多个拨料杆44,所述拨料轴43的前端伸出料斗3经皮带传动连接到其中一个输送辊5上。该拨料杆44可以有多组,多组拨料杆44沿着拨料轴43长度方向间隔设置,每组拨料杆44圆周均布在拨料轴43上,相邻两组拨料杆44在圆周方向上交错设置。

实施例8,在实施例7的基础上,所述拨匀装置包括沿着输送带6宽度方向设置的固定在支撑杆53下端的第三连杆55,所述第三连杆55上均布有多个拨匀杆56。该拨匀杆56上可以转动连接一个螺栓,该螺栓旋拧在第三连杆上,然后在拨匀杆和第三连杆之间再连接一个伸缩杆进行限位使得拨匀杆56不能转动即可。这样设置使得任一拨匀杆56都可以根据需要进行调节其到输送带之间的间隔。
实施例9,在实施例1的基础上,两所述输送辊之间设有张紧辊57,所述张紧辊57压在输送带5的下层带上,所述张紧辊57前后端转动连接有轴承座58,所述张紧辊57前后端的机架1上开有竖向的长条形滑孔59,所述轴承座58上固定有伸出滑孔59的紧固杆60,该紧固杆60滑动配合在滑孔59内且伸出滑孔59的部分上旋拧有压在机架1上的紧固螺母61。轴承座58覆盖在该滑孔59上,也就是说滑孔59的横向尺寸小于轴承座58,松开紧固螺母61,可以上下移动张紧辊57来调节输送带6的张紧度,当调节好输送带6的张紧度后,拧紧紧固螺母61即可。
实施例10,在实施例1的基础上,所述导料壳67上端转动连接在机架1上,导料壳67和机架1之间设有长度可调的连接杆71,该连接杆71的两端分别铰接在导料壳67和机架1上。所述连接杆71铰接在导料壳67的位置位于导料壳67与机架1的转动连接部,连接杆71铰接在导料壳67面朝机架1的侧壁上。所述连接杆71包括中间的调节筒72以及置于调节筒72两端的第一调节杆73和第二调节杆74,第一调节杆73和第二调节杆74分别螺纹连接在调节筒72内,第一调节杆73上的外螺纹与第二调节杆74上的外螺纹旋向相反,所述第一调节杆73铰接在导料壳67上,第二调节杆74铰接在机架1上。所述调节筒72上套固有调节螺母75,加有调节螺母75方便工人用扳手夹持调节螺母75对调节筒72进行旋转。旋转调节筒72,使得第一调节杆73和第二调节杆74在调节筒72内转动,由于旋向相反,第一调节杆73和第二调节杆74相对靠近或远离,则连接杆71的长度增加或减小,由于连接杆71两端铰接在机架1上导料壳67上,因此连接杆71的长度的改变可以使得导料壳67的倾斜角度改变,导料壳67的倾斜角度的改变使得下料口69到地面的距离改变,可以根据需要铺设的石灰粉的厚度来调节下料口69到地面的高度,设置导料壳67,使得石灰粉出口到地面的距离更近,进一步保证了石灰粉厚度铺设均匀,且由于石灰粉出口到地面距离近,也有效的遏制了石灰粉的飘洒,降低了大气的污染。
本发明使用时,在机架1右侧装有扶手63,可以人工拉着该机架1进行行走施工,也可以通过拖拉机等动力车牵引着该装置进行行走,当机架1被牵引时,行走轮2转动,行走轮2的转动经速度比调节装置带动输送带6运动,输送辊5的运动带动拨料轴43转动,拨料轴43带动拨料杆44转动,拨料杆44使得料斗3内的物料向下掉落到输送带6上,物料掉到输送带6上之后由于设置宽度挡料板8,两个第一板801之间的宽度大于料斗3的下料宽度,使得物料可以完全进入到两第一板801内,而第二板802终端的宽度小于料斗3的下料宽度,有效的保证了出料的宽度,物料经过宽度挡料板8之后经过厚度挡料板7,厚度挡料板7的可调节的最大高度低于料斗3下料口到输送带6的高度,这样保证了输送带6的出料厚度,而输送辊5和行走轮2的速度比以及厚度挡料板7的高度均是可调的,由于该发明中的石灰粉在输送带6上的出料宽度是定值,而公路上铺设的宽度等于输送带6输出的宽度(虽然会有误差,但是误差在可接受范围内,同样可以使得铺设石灰粉的精度高于普通的铺设方式),而输送带6上每秒输出的石灰粉等于公路上铺设的石灰粉的。因此可以设输送带6输出的石灰粉的宽度W1,输送带6输出时的石灰粉的厚度为H1,每秒输出的石灰粉的长度为V1(输送辊5的线速度),每秒输出的石灰粉的体积为S1,公路上得到的石灰粉的宽度为W2,公路上得到的石灰粉的厚度为H2,公路上得到的石灰粉长度为V2(行走轮2的线速度),每秒公路上得到的石灰粉的体积为S2,可以得出S1=W1*H1*V1,S2=W2*H2*V2,因为S1=S2,得出W1*H1*V1 =W2*H2*V2,因为W1=W2,因此可以推导出H2=H1*V1/V2,可得出公路上石灰粉铺设的厚度为输送带6上石灰粉的厚度乘于石灰粉输送辊5的线速度除于行走轮2的线速度,由于线速度等于角速度乘于半径,而输送辊5的半径和行走轮2的半径已经确定,因此调节公路上得到的石灰粉的厚度可以通过调节厚度挡料板7的高度以及输送辊5和行走轮2的转速比来进行调节,当厚度挡料板7的高度增高或输送辊5和行走轮2的速度比增大时,公路上铺设的石灰粉厚度增加。在石灰粉铺设厚度调节的过程中,先调节厚度挡料板7的高度,如果是需要调节使得石灰粉厚度增加,那么先调节厚度挡料板7的高度,使得工人拉动机架1时用的力变化不大,而如果不调节厚度挡料板7直接调节速度比,使得工人在同样的行走速度下作用到输送辊5上的转速增加,必然需要增加工人的拉力,加大了工人的劳动强度,因此在设计的时候是在允许的范围如果增大石灰粉的铺设则优先调节石灰粉挡板的高度,这样节省了工人的力气,当然石灰粉挡料板的高度不能无限制的升高,至少其要低于料斗3出料口的高度,因此当挡料板高度调节到最高限值时如果还想增加石灰粉的铺设厚度,则调节速度比即可。该石灰粉设有宽度挡料板8和厚度挡料板7也保证了石灰粉铺设的均匀性。当然除了使用刻度盘16调节石灰粉铺设厚度,也可以通过测量铺设后的石灰粉厚度来来调节动力轴。当然要想进一步增加精度,且达到快速调节的作用,则先根据刻度盘16调节到需要的精度,此时可能会存在一些误差,此时再根据铺设后的石灰粉厚度的测量来反馈,再对动力轴13进行微调,可达到快速且精准的调节石灰粉厚度。
