The invention discloses a lateral clamping type carrot harvesting monomer, and belongs to the technical field of agricultural machinery. The harvesting single body comprises a machine frame, a crawler-type chassis, a ploughshare type furrow opener, a leaf supporting mechanism, a transverse clamping and conveying mechanism, a righting curved surface, a conveying belt with a baffle and a leaf and fruit separating mechanism, wherein the ploughshare type furrow opener, the leaf supporting mechanism, the transverse clamping and conveying mechanism and the righting curved surface are sequentially arranged in the advancing direction. The carrots and the soil are turned up and guided to one side of the machine tool by the ploughshare type furrow opener; the tassel lifting mechanism lifts tassels straight and guides the tassels into the transverse clamping and conveying mechanism; the transverse clamping and conveying mechanism clamps the tassels to transversely convey the tassels in the direction perpendicular to the advancing direction of the machine tool, and the root fruits naturally droop due to gravity. The centralizing curved surface centralizes the vertically suspended root fruits into a horizontal posture; the conveying belt with the baffles keeps the horizontal postures of the roots and the fruits and continues conveying; the tassel and fruit separating mechanism adopts a high-speed rotating disc cutter to accurately cut off tassel and fruit joints at a unified position. By means of an innovative lateral conveying mode, the problems that in an existing longitudinal conveying technology, tassel postures are different, the net cutting rate is low, and the structure is complex are solved, and the device has the advantages of being simple in structure, accurate in separation, low in damage rate and high in operation efficiency.

The invention discloses a self-edge-searching flexible attaching and chamfering device which comprises a plate carrying table and a displacement carrying base. A follow-up attaching mechanism is arranged on the displacement carrying seat and comprises a floating base, a floating carrying seat and an elastic floating assembly connected with the floating base and the floating carrying seat. The floating base is provided with a horizontal limiting part used for limiting the floating carrier seat to move in the horizontal plane, and when the floating carrier seat is subjected to abutting force in any horizontal direction, the elastic floating assembly generates elastic reset force on the floating carrier seat. A chamfering main shaft mechanism is arranged on the floating carrier seat, and the axial direction of a chamfering main shaft is vertical. Omnidirectional horizontal flexible follow-up fitting can be achieved, steering adjustment is not needed, and the chamfering fitting degree and uniformity are greatly improved. The posture of the cutter is stable, inclination and deviation are avoided, and chamfered surfaces are straight and consistent. And vertical bidirectional floating compensation is achieved, overcutting and missed cutting are eradicated, and it is guaranteed that the cutting depth is uniform. The track planning precision requirement is lowered, high-precision scanning is not needed, operation is simplified, and the machining efficiency is remarkably improved.

The application relates to the technical field of television equipment processing, in particular to a television face frame material head automatic cutting machine, which comprises a machine base and a placing frame for placing a face frame, a limiting column for positioning the face frame is arranged on the placing frame, the limiting column is provided with a plurality of limiting columns and is arranged in a rectangular shape, a pressing mechanism for pressing the face frame and a cutting mechanism for cutting off the material head on the face frame are arranged on the machine base, a discharging port for discharging the cut-off material head is arranged on the machine base, and a waste collecting mechanism for collecting the material head is arranged in the machine base; the limiting columns on the placing frame are arranged in a rectangular shape, a worker can quickly and accurately position the face frame on the placing frame, the face frame is pressed by the pressing mechanism, and the stability of the face frame during cutting is guaranteed; meanwhile, the cutting mechanism can accurately control the cutting force and angle to cut the material head, the face frame is prevented from being cracked or scratched, and the automatic cutting of the material head on the face frame is realized.

The invention relates to the technical field of tea planting, and discloses tea trimming equipment for tea planting, which comprises a cross beam, two upright posts, rollers arranged at the bottom of the cross beam, first sliding rails arranged at the bottoms of the upright posts, pushing handles arranged at the bottoms of the rollers, cutters arranged on the back surfaces of the upright posts, and a first support arranged between the two upright posts, the diameter adjusting mechanism is arranged above the cutter, the self-adaptive adjusting effect of the surrounding diameter of the cutter is achieved through the diameter adjusting mechanism, a movable rod is driven by an electric telescopic rod to drive a second sliding block to slide along a second sliding groove, flexible scaling of the surrounding radius of the cutter is achieved, the leaf crown diameters of tea trees of different ages and varieties can be accurately matched, and the practicability is high. In addition, the first motor is matched to drive the gear to be in meshing transmission, so that the cutter stably surrounds the tea tree, and the precision and adaptability of the pruning operation are further improved.
