Цепочно-планчатый конвейер включает раму 1 с установленными на ней ведущим валом 2 с парой звездочек 3 и ведомым валом 4 с парой звездочек 5. Звездочки 3 и 5 огибаются двумя па- щ раллельными цепными контурами 6 и 7, на которых шарнирно закреплены планки 8 с пальцами 9.The chain-and-belt conveyor includes a frame 1 with a drive shaft 2 mounted on it with a pair of sprockets 3 and a driven shaft 4 with a pair of sprockets 5. The sprockets 3 and 5 are bent around by two parallel chain circuits 6 and 7, on which the straps 8 sec. with fingers 9.

Установочное приспособление выполнено в виде размещенного параллельно ₁₅двум цепным контурам дополнительного цепного контура 10 со звездочками 11 и 12, которые насажены на дополнительные валы 13 и 14 в виде кривошипа 15, один конец которого закреплен на ₂₀ планке 8, а другой шарнирно через палец 16 закреплен на дополнительном цепном контуре 10.Positioning means is in the form disposed parallel ₁₅ two chain loops additional chain loop 10 with sprockets 11 and 12 which are planted on the additional shafts 13 and 14 in the form of a crank 15, one end of which is fixed to ₂₀ bar 8, and the other is articulated via a pin 16 fastened on an additional circuit 10.

При этом дополнительный вал 13 относительно ведомого вала 4, а дополнительный вал 14 относительно ведущего вала 2 смещены на расстояние, равное длине кривошипа 15. Звездочка 12 жестко посажена на дополнительном валу 14 соосно со звездочкой 17 ₃₀ цепной передачи 18, звездочка 19 которого жестко посажена на приводном валу 2.Moreover, the additional shaft 13 relative to the driven shaft 4, and the additional shaft 14 relative to the drive shaft 2 are offset by a distance equal to the length of the crank 15. The sprocket 12 is rigidly mounted on the additional shaft 14 coaxially with the sprocket 17 _{30 of the} chain gear 18, the sprocket 19 of which is rigidly mounted on drive shaft 2.

Цепочно-планчатый конвейер работает следующим образом.Chain-belt conveyor operates as follows.

При вращении ведущего вала 2 кру- ³⁵тящий момент передается через звездочки 17, 19, 12 и 3 на цепные контуры 6, 7 и 10, которые., в свою очередь, заставляют перемещаться планки 8 с пальцами 9 и кривошипы 15.When the drive shaft 2 rotates steep tyaschy ³⁵ is transmitted through sprockets 17, 19, 12 and 3 in the chain contours 6, 7 and 10, which., In turn, cause the slats to move fingers 8 to 9 and the cranks 15.

Звездочки 11 и 12 дополнительного контура 10 имеют одинаковый диаметр и число зубьев со звездочками 3 и 5 4ί смещены относительно них на расстоя ние, равное кривошипу. Тем самым пальцы планок работают точно в заданном положении.Sprockets 11 and 12 of additional contour 10 have the same diameter and the number of teeth with sprockets 3 and 5 4ί are offset relative to them by a distance equal to the crank. Thus, the fingers of the strips work exactly in the given position.

Положительный эффект состоит в том, что выполнение установочного приспособления в виде кривошипа и дополнительного цепного контуре позволяет осуществить строго заданное положение рабочего органа в виде планки с пальцами, что влечет за собой повышение надежности и долговечности конвйера.The positive effect is that the installation of the installation device in the form of a crank and an additional chain circuit allows you to implement a strictly specified position of the working body in the form of a strap with fingers, which entails an increase in the reliability and durability of the conveyor.

Claims

() CHAIN-PLANNED CONVEYOR This invention relates to the industry of continuous transport and can be used in agricultural engineering. A chain conveyor is known, which includes a frame, a drive and a driven shaft and sprockets mounted on them, bending around the flj traction unit. However, this conveyor is not reliable and durable. The closest technical solution to the invention is a chain-slat conveyor, which includes a frame, drive and driven shafts with asterisks, envelopes their two parallel chain links, which are connected to each other by means of pins with fingers, which are hinged on them, and an adjusting device with cranks, one end each of which is fixed on the corresponding, strap, and the other is installed with the possibility of interaction with the profiled track 2. However, during long-term operation, a profiled track is developed and skewed, as a result of which the roller leaves the mesh, and the fingers do not capture the mass. The aim of the invention is to increase reliability and durability. The goal is achieved by the fact that in a chain-iHo-slat conveyor, which includes a frame, drive and driven shafts and sprockets, enveloping their two parallel chain contours connected between them by means of fingers hinged to them, and an adjusting device with cranks, one end each of which is fixed on the appropriate bar, the adjusting device is made in the form of an additional chain contour located parallel to the two chain loops with the shafts, which are located relative to the driving and driven shafts crank, with a free end. 39 of each crank is hinged on the additional circuit circuit. FIG. t depicts a chain-slat conveyor, side view; Figure 2 is the same, top view. The chain-slatted conveyor includes a frame 1 with a drive shaft 2 installed on it, a pair of sprockets 3 and a driven shaft t with a pair of sprockets B "The sprockets 3 and 5 envelope by two parallel chain contours 6 and 7 on which the bars 8 with fingers 9 are hinged. The adjusting device is made in the form of an additional chain loop 10 placed parallel to the two chain loops with sprockets 11 and 12, which are mounted on the additional shafts 13 and H in the form of a crank 15, one end of which is fixed on the bar 8 and the other hingedly through The lec 16 is fixed on the additional chain contour 10. At the same time, the additional shaft 13 is relative to the driven shaft k, and the additional shaft 1 relative to the drive shaft 2 is shifted a distance equal to the length of the crank 15. An asterisk 1 2 is rigidly mounted on the additional shaft 1 coaxially with an asterisk 17 chain transmission 18, the sprocket 19 of which is rigidly seated on the drive shaft 2. Chain-slatted conveyor works as follows. As the drive shaft 2 rotates, the torque is transmitted through the sprockets 17, 19 12 and 3 to the chain loops 6, 7 and 10, which, in turn, cause the strips 8 to move with the fingers 9 and the crankshaft 15. The asterisks 11 and 12 are additional The contour 10 has the same diameter and number of teeth with 3 and 5 fi stars offset from them by a distance of 34 equal to the crank. Thus, the fingers of the slats work exactly in the set position. The positive effect is that the implementation of the installation device in the form of a crank and an additional chain loop allows you to carry out a strictly specified position of the working body in the form of a finger bar, which entails an increase in the reliability and durability of the conveyor. Claim chain conveyor comprising a frame, drive and driven shafts with asterisks, envelopes of two parallel chain loops interconnected by planks with fingers hinged on them, and crank fixtures, one end of each of which is fixed on the corresponding plank , characterized in that, in order to increase its reliability and durability, the mounting device is made in the form of an additional chain loop arranged parallel to two chain loops with shafts that are arranged with respect to the driving and driven shafts konturrv two parallel spaced, equal length kriboshipa, wherein the free end of each crank is pivotally mounted on an additional circuit loop.
