The invention provides a device for automatically producing a regular positioning net. The device comprises a mechanical arm, a first feeding structure, a second feeding structure, a third feeding structure, a welding table, a welding assembly and a grabbing assembly. The second feeding structure and the third feeding structure are matched with the welding table to complete the welding work of the second transverse rib and the vertical rib; after welding of the second transverse bars and the vertical bars is completed, the second transverse bars and the vertical bars are transferred to the position above the welding assembly through the mechanical arm and are in lap joint to third transverse bars on the welding assembly, a plurality of reinforcing meshes formed by welding of the second transverse bars and the vertical bars are welded through the welding assembly, and a regular reinforcing mesh is formed; the whole production process is unmanned, automatic production of regular reinforcing meshes is achieved, the reinforcing steel bar lap joint and welding process is automatic welding, manpower and time consumption is reduced, the production cost is reduced, and efficiency is high; and meanwhile, potential safety hazards to workers are avoided, the welding error is relatively small, and the yield is increased.

The utility model discloses a kind of flat steel clamping assembly structure, including assembly groove and clamp, clamp includes two clamping pieces oppositely arranged along assembly groove extension direction, each clamping piece sequentially includes locking portion, clamping portion and with the stop portion of assembly groove cooperation, the clamping space for fixing flat steel is enclosed between the clamping portion of two clamping pieces and assembly groove;Clamping portion is L-shaped as a whole, including the first clamping section and the second clamping section of mutual connection, the end of first clamping section away from the second clamping section is connected with locking portion, the end of second clamping section away from first clamping section is connected with stop portion, locking portion and stop portion extend in direction of away from first clamping section, the end of first clamping section and locking portion compared with the end of first clamping section and second clamping section connection is inclined to the inside of clamping space. The above structure effectively improves the convenience, flexibility, reliability and versatility of flat steel clamping structure / device actual use.

The utility model relates to the field of fertilizing devices, in particular to a fertilizing device for vegetation recovery, which comprises a feed hopper, a support bracket, a sliding part, a lifting part, a tensioning part, a transmission part, a cam, a transmission shaft, a blanking shell and a filter screen, the outer end face side face of the feeding hopper is connected with multiple sets of supporting supports. The bottom of the feeding hopper is connected with a discharging shell, the side face of the discharging shell is rotationally connected with a transmission shaft, and multiple blocking plates are arranged on the side face of the transmission shaft. One end, far away from the transmission shaft, of the linkage belt is in transmission connection with the cam; the side of the cam is rotationally connected with the inner wall of the feed hopper; the cam contacts with the bottom of the filter screen; a supporting ring is arranged on the inner wall of the feeding hopper; the rolling wheels are used as a power source in a belt transmission mode, the power transmission efficiency of the device can be effectively improved, the situation that a motor is used in the device is avoided, and the production cost of the device is reduced.

The invention discloses a block copolymer binder and a preparation method and application thereof.The block copolymer binder is prepared through a template polymerization method and comprises a silicon-loving chain segment composed of repeating units of a silicon-loving monomer and a flexible chain segment composed of repeating units of a flexible monomer, the silicon-loving monomer is a monomer which has a polar group and can be connected with the silicon particles through chemical bonds. According to the segmented copolymer binder provided by the invention, the flexible chain segments and the silicon-philic chain segments are distributed at intervals on a molecular chain, so that the adhesion of the silicon-philic chain segments can be better played, the flexibility and processability of the binder are improved, and an electrode pole piece with good flexibility and stability can be prepared.
