Description
(54) ИЗМЕРИТЕЛЬНЫЙ ЗУБ КОВША ЗЕМЛЕРОЙНОЙ МАШИНЫ(54) MEASURING TOOTH BUCKET DIGGER MACHINE
Изобретение относитс к области разработки и транспортировки грунта и может быть использовано в измерительных зубь х ковшей землеройных машин. Известны измерительные зубь ковшей землеройных машин, включающие корпус с передней и задней гран ми и тензоэлементы 1. Недостатком таких зубьев вл етс то, что они не позвол ют измерить давление грунта на режушей кромке. Известны также измерительные зубь ковшей землеройных машин, включающие корпус с передней и задней гран ми и тензоэлементы 2. Недостаток их - мала точность измерени . Цель изобретени - повышение точности измерени давлени грунта на зуб. Поставленна цель достигаетс тем, что передн грань выполнена с продольным пазом по всей ее ширине под тензоэлементы, которые выполнены в виде нат нутых электроизолированных проволок, расположенных поперек передней грани зуба. На фиг. 1 и 2 приведены две проекции измерительного зуба ковша землеройной мащины; на фиг. 3 - продоЛьное осевое сечение зуба; на фиг. 4 - с.ечение А-А на фиг. 2. Измерительный зуб ковша землеройной машины состоит из корпуса 1 с продольным пазом 2 на передней грани 3, охватывающим длину режущей кромки, отдельных электроизолированных проволочек 4, закрывающих паз и нат нутых в поперечном направлении зуба, зажимных планок 5 с винтами 6, фольги 7, огибающей переднюю и заднюю грань зуба. Один конец фольги закреплен на передней грани винтом 8, второй - на задней грани винтом 9. Кажда проволочка уложена в отдельный желоб полукруглого сечени Проволочки также электроизолированы от корпуса зуба зажимных планок и фольги. К каждой проволоке, выполн ющей роль тензодатчика сопротивлени , со стороны паза на некотором рассто нии друг от друга присоединены два проводка. Дл вывода проводов 10 имеетс отверстие 11. Латунна фольга толщиной 0,1-0,2м предназначена дл предохранени изол ции проволочек от повреждени и попадани грунта внутрь паза зуба. Роль режущей кромки зуба выполн ет электроизолированна проволочка с радиуThe invention relates to the development and transportation of soil and can be used in measuring teeth of earthmoving machinery. Measuring teeth of buckets of earth-moving machines are known, including a housing with front and rear edges and tenso-elements 1. The disadvantage of such teeth is that they do not allow measuring the pressure of the soil on the cutting edge. Measuring teeth of buckets of earth-moving machines are also known, including a housing with front and rear faces and tenso-elements 2. Their disadvantage is the low measurement accuracy. The purpose of the invention is to improve the accuracy of measuring soil pressure per tooth. The goal is achieved by the fact that the front face is made with a longitudinal groove across its entire width under the strain elements, which are made in the form of tensioned electrically insulated wires located across the front face of the tooth. FIG. 1 and 2 shows two projections of the measuring tooth of the bucket of the earthmoving equipment; in fig. 3 - long axial section of the tooth; in fig. 4 - sec. Section AA in FIG. 2. The measuring tooth of the bucket of the earth-moving machine consists of a body 1 with a longitudinal groove 2 on the front face 3, covering the length of the cutting edge, separate electrically insulated wires 4, covering the groove and tensioned in the transverse direction of the tooth, clamp bars 5 with screws 6, foil 7 envelope front and back of the tooth. One end of the foil is fixed on the front face with a screw 8, the other is on the rear face with a screw 9. Each wire is laid in a separate trough of a semi-circular section. The wires are also electrically insulated from the tooth body of the clamping strips and the foil. Two wires are connected to each wire, which acts as a resistance strain gauge, from the groove side at some distance from each other. A hole 11 is provided to lead the wires 10. A brass foil 0.1-0.2 m thick is designed to protect the insulation of the wires from damage and the ingress of soil into the groove of the tooth. The role of the cutting edge of the tooth is performed by an electrically insulated wire with a radius
