本实用新型涉及物料输送及计量技术领域，尤其涉及一种皮带称 量输送装置和搅拌站。 背景技术
皮带秤是一种应用于搅拌站和物料输送系统中的计量装置，用于 对放置在皮带上并随皮带连续通过的松散物料进行自动称量。 目前， 广泛使用的皮带秤主要包括滚轮皮带秤和电子皮带秤， 其中， 滚轮皮 带秤由滚轮连动机构、 称量盘、 积分器、 数码表和箱壳组成， 通过积 分器连续累计带式输送机运载物料的负荷，并将累计结果通过数码表 显示； 电子皮带秤由承重装置、 称重传感器、 速度传感器和称重显示 器组成， 承重装置将皮带上物料的重力传递到称重传感器， 物料速度 输入速度传感器，运算器对称重传感器和速度传感器的输出结果进行 计算和累计， 即可得到皮带上连续通过的物料总量。
由于皮带秤的负载具有不稳定性， 变化范围较大， 尤其是对于间 歇式皮带种， 通常需要频繁的带载启动， 在使用过程中会出现电机带 载启动电流过大和皮带打滑等现象。 现有技术中， 可以对皮带秤的负 载设计较大的盈余， 通过增加皮带秤的电机容量的方式， 扩大皮带秤 装置适应负载变化的能力。
发明人在实现本发明的过程中， 发现现有技术至少存在以下缺 点：
通过增加电机容量， 虽然能够适应皮带秤的负载变化， 但是会造 成设计盈余的浪费， 性价比较低。 实用新型内容
本实用新型实施例提供了一种皮带称量输送装置和搅拌站，用于 调节皮带承受的负载。
本实用新型实施例提供了一种皮带称量输送装置， 包括： 皮带
( 110 )和挡料板（ 120 ), 所述挡料板（ 120 )位于所述皮带 （ 110 ) 和所述皮带（ 110 )输送的物料之间， 通过改变所述挡料板（ 120 )与 所述皮带（ 110 )之间的位置关系和 /或角度关系，调节所述皮带（ 110 ) 的实际负载。
本实用新型实施例还提供了一种搅拌站， 包括所述皮带称量输送 装置。
本实用新型实施例在皮带称量输送装置上增加了角度和位置可 调的挡料板结构， 构造筒单， 实现方便， 通过调节挡料板能够根据现 场输送或配料的实际负载情况随时调节皮带的实际承受载荷，有效扩 大了皮带称量输送装置适应负载变化的能力， 减少了现场改装工作 量；可现场调试，能够消除皮带机带载启动跳闸、堵转或打滑等缺陷， 确保输送系统的稳定性； 减少设计盈余浪费， 降低能耗； 可以有效地 降低皮带机的型号规格， 扩大标准化内容。 附图说明
图 1为本实用新型实施例中皮带称量输送装置结构示意图； 图 2为本实用新型实施例中皮带称量输送装置的板体、耐磨板和 支撑杆结构示意图。
具体实施方式
下面将结合本实用新型实施例中的附图，对本实用新型实施例中 的技术方案进行清楚、 完整地描述， 显然， 所描述的实施例仅仅是本 实用新型一部分实施例， 而不是全部的实施例。基于本实用新型中的 实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的 所有其他实施例， 都属于本实用新型保护的范围。
如图 1所示，为本实用新型实施例中皮带称量输送装置结构示意 图， 包括： 皮带 110和挡料板 120, 挡料板 120位于皮带 110和皮带 110输送的物料之间， 通过改变挡料板 120与皮带 110之间的位置关 系和 /或角度关系， 可以调节皮带 110的实际负载。 皮带 110下方装 设有托滚 130, 该托滚 130支撑皮带 110及皮带 110承载的物料， 以 降低皮带 110所受的纵向张力。
具体地， 上述挡料板 120包括板体 121、 支撑杆 122、 铰链 124、 第一活动支点 125和第二活动支点 126, 支撑杆 122与皮带称量输送 装置的侧面连接， 用于支撑板体 121。
本实用新型实施例中的皮带称量输送装置的侧面设有 U 形槽 140, 第一活动支点 125和第二活动支点 126位于 U形槽 140中， 并 可在 U形槽 140中滑动， 通过改变第一活动支点 125和 /或第二活动 支点 126的位置， 调节挡料板 120与皮带 110之间的位置关系和 /或 角度关系。 皮带称量输送装置侧面的 U形槽 140的个数可以为一个， 也可以为多个；第一活动支点 125和第二活动支点 126可以位于同一 个 U形槽 140中， 也可以位于不同的 U形槽 140中。
如果皮带 110输送的物料重量一定，挡料板 120处于位置 2时皮 带 120所受的压力，小于挡料板 120处于位置 1时皮带 120所受的压 力。 因此， 当皮带 110输送的物料重量较小时， 可以通过移动第一活 动支点 125和第二活动支点 126, 来调节挡料板 120的位置， 例如， 将挡料板 120的位置调整在位置 1处，则物料直接与皮带 110接触的 面积和皮带 110的受力均增加， 可以增加物料的输送速度， 但需要保 证皮带 110的受力不大于启动额定载荷。
当皮带 110输送的物料重量变化较大时，通过移动第一活动支点 125和第二活动支点 126, 来调节挡料板 120的位置， 使得皮带 110 的实际载荷在电机额定驱动能力之内。 例如， 将挡料板 120调至位置 2, 则物料直接与皮带 110接触的面积和皮带 110的受力均减小， 虽 然降低了输送速度， 但能够确保电机的正常驱动。
需要说明的是， 改变挡料板 120的位置和角度的方法， 可以是手 动或自动， 可以靠人力、 气动或液压等方式。 本实用新型实施例所描 述的是实现挡料板 120位置和角度调节的一种筒单实用的结构和方 法，任何通过改变挡料板 120位置和角度调节皮带 110载荷的结构和 方法都属于本实用新型的保护范围。
此外， 为了减少挡料板 120与皮带 110之间的摩擦， 可以在板体 121的下边沿装设有耐磨板 123, 如图 2所示。 板体 121、 耐磨板 123 和支撑杆 122均成对出现， 以皮带 110中心线为中心对称分布， 共同 构成挡料板 120。 当调节板体 121、 耐磨板 123和支撑杆 122的位置 时， 也需要成对调节。
本实用新型实施例针对现有皮带称量输送装置带载启动电流较 大、适应负载变化范围较小的问题， 在皮带称量输送装置上增加了角 度和位置可调的挡料板结构， 构造筒单， 实现方便， 通过调节挡料板 能够根据现场输送或配料的实际负载情况随时调节皮带的实际承受 载荷， 有效扩大了皮带称量输送装置适应负载变化的能力， 减少了现 场改装工作量； 可现场调试， 能够消除皮带机带载启动跳闸、 堵转或 打滑等缺陷，确保输送系统的稳定性；减少设计盈余浪费，降低能耗； 可以有效地降低皮带机的型号规格， 扩大标准化内容。
本实用新型实施例还提供了一种搅拌站，该搅拌站包括皮带称量 输送装置， 所述皮带称量输送装置包括皮带和挡料板， 所述挡料板位 于所述皮带和所述皮带输送的物料之间 ,通过改变所述挡料板与所述 皮带之间的位置关系和 /或角度关系， 调节所述皮带的实际负载。
具体地， 所述挡料板包括板体和支撑杆， 所述支撑杆与所述皮带 称量输送装置的侧面连接， 用于支撑所述板体。 所述挡料板还包括耐 磨板， 所述耐磨板装设于所述板体的下边沿。 其中， 板体、 耐磨板和 支撑杆均成对出现，以皮带中心线为中心对称分布，共同构成挡料板。 当调节板体、 耐磨板和支撑杆的位置时， 也需要成对调节。
上述挡料板还包括铰链、 第一活动支点和第二活动支点， 所述皮 带称量输送装置的侧面设有 U形槽， 所述第一活动支点和所述第二 活动支点位于所述 U形槽中， 并可在所述 U形槽中滑动， 通过改变 所述第一活动支点和 /或所述第二活动支点的位置， 调节所述挡料板 与所述皮带之间的位置关系和 /或角度关系。 上述 U形槽为一个或多 个， 所述第一活动支点和所述第二活动支点位于相同或不同的 U形 槽中。
本实用新型实施例中的搅拌站在皮带称量输送装置上增加了角 度和位置可调的挡料板结构， 构造筒单， 实现方便， 通过调节挡料板 能够根据现场输送或配料的实际负载情况随时调节皮带的实际承受 载荷， 有效扩大了皮带称量输送装置适应负载变化的能力， 减少了现 场改装工作量。 以上所述仅是本实用新型的优选实施方式， 应当指出， 对于本技 术领域的普通技术人员来说， 在不脱离本实用新型原理的前提下， 还 可以做出若干改进和润饰，这些改进和润饰也应视本实用新型的保护 范围。
