Description
Изобретение касаетс горной промьвиленности , а именно исполнительных органов бурошнековой машины дл выемки угл . Из основного авт. св. Ns 314889 известен исполнительный орган бурошне ковой машины, включающий буровые коронки , соединенные шнековым ставом с вращателем машины, и неврйщаюшийс став, соединенный с ее подающим низмом. Невращающийс став, выполнен в виде фермы, на боковых сторонах которой закреплены кронштейны, несущие подшипники с установленным в них шне- ковым ставом. На боковых сторонах фермы параллельно ее продольной оси закреплены дугообразные щитки охватьшаю- щие с зазором шнековый став. Верхние концы дугообразных щитков наход тс вы ше верхней части фермы. Невращающийс и шнековые ставы состо т из отдельных, соедин емых между собой секций.СПНедостатком такого исполнительного органа бурсшнековой машины вл етс то, что куски угл или породы, вьталивающиес из кровли скважины, скапливаютс в пространстве, образованном верхней поверхностью, фермы и дугообразными щитками, а это приводит к заклиниванию исполнительного органа в скважине, что снижает надежность его работы. Целью изобретени вл етс повышение надежности работы исполнительного органа бурошнековой машины. Это достигаетс тем, что верхн часть фермы выполнена в виде двух наклонных поверхностей и установлена с воз можностью контакта с дугообразными щитками. На фиг. 1 показан исполнительный орган бурошнековой машины, вид сверху| на фиг. 2 - разрез А-А фиг. 1. Исполнительный орган бурошнековой машины вкгаочает буровые коронки 1, крайние из котфых соединены шнековым ставом 2 с вращателем машины 3, а средние привод тс во вращение при поThe invention relates to the mining industry, namely the executive bodies of the auger mill for coal excavation. From the main auth. St. Ns 314889 is known for the executive body of a drill machine, including drill bits, connected by a screw rod to the rotator of the machine, and non-halych stand, connected to its feeding base. The non-rotating stand is made in the form of a truss, on the sides of which there are brackets fixed, bearing bearings with a screw stand installed in them. On the sides of the truss, parallel to its longitudinal axis, arcuate shields of a screw stand are attached with a gap. The upper ends of the arcuate plates are located above the top of the truss. Non-rotating and screw staves consist of separate, interconnected sections. The disadvantage of such an executive body of the burrowing machine is that pieces of coal or rock penetrating from the roof of the well accumulate in the space formed by the upper surface, trusses and arcuate shields, and This leads to the seizure of the executive body in the well, which reduces the reliability of its operation. The aim of the invention is to increase the reliability of the executive body of the drilling machine. This is achieved by the fact that the upper part of the truss is made in the form of two inclined surfaces and is installed with the possibility of contact with arcuate shields. FIG. 1 shows the executive body of a boring machine, top view | in fig. 2 - section A-A of FIG. 1. The executive body of the boring machine includes drill bits 1, the outermost of the pumps are connected by a screw rod 2 to the rotator of the machine 3, and the middle ones are rotated at
