The invention discloses a building decoration waste dustproof crushing and recycling device and a recycling process, and relates to the technical field of building decoration construction, the recycling device comprises a dustproof case and a crusher, one side of the dustproof case is provided with a feeding port, and the crusher is arranged at the bottom of the dustproof case; one side of the bottom of the crusher is provided with a recovery port for discharging crushed waste; the device further comprises an auxiliary feeding mechanism, and the auxiliary feeding mechanism comprises an overturning supporting plate and an auxiliary butt clamping mechanism. According to the waste crushing and recycling device, when waste is driven to be fed from the feed port formed in the side through the overturning action of the overturning supporting plate, the crushing clamping plates distributed on the two sides of the overturning supporting plate in pairs automatically conduct butt clamping towards the middle, the ultra-long waste within a certain size range is conveniently crushed and centered, and therefore the waste can fully and effectively enter the device from the feed port to be crushed and recycled.

The present application relates to a kind of full automatic stamping product automatic unloading device, including first slide and second slide, the bottom end of the first slide is equipped with connecting plate.The present application detects that the current zero component along the first slide is NG product, connecting plate will be opened immediately, then NG zero component will fall into the first slide and the second slide break, and be collected uniformly, and connecting plate opening will drive sealing plate to move along the first slide slope in the inside of sealing box, and its edge is slid on the slope of top block, so that sealing plate is separated from the bottom slope of the first slide, air groove is conducted, while crank mechanism is opened fan by pressing switch in the process of rotation, and the qualified zero component behind sliding is adsorbed and slowed down, to avoid that qualified product falls into the break of the first slide and the second slide due to not closing connecting plate in the process of sliding, without affecting the zero component after NG product to continue unloading, but quickly screening NG product, applicable to relatively fast stamping production line.

The utility model provides a kind of precision pesticide application device for tobacco disease, belong to tobacco disease control technical field. Including base, base top is equipped with medicine box, both side walls of medicine box are equipped with spray pesticide subassembly, spray pesticide subassembly includes support block one, for driving the drive part of support block one lifting, both side walls of support block one are symmetrically equipped with electric push rod two, the telescopic rod end of electric push rod two is equipped with support block two, support block two bottom is equipped with spray pipe, spray pipe bottom is equipped with C type frame, C type frame inner bottom is equipped with laser range finder, C type frame outer bottom is equipped with spray head two, spray pipe and spray head two between are equipped with three-way valve. The utility model through spray pesticide subassembly, under the joint action of drive part, electric push rod one, electric push rod two, laser range finder etc., can be accurately to stem and leaf, root pesticide application according to tobacco disease condition, improve the utilization rate of liquid medicine resource, effectively prevent considerable part of the sprayed liquid medicine to do useless work, realize the precision pesticide application to tobacco plant.

The invention belongs to the technical field of optical cable laying, and provides a comprehensive cable channel circulating relay type optical cable traction laying method, which comprises the following steps of: S1, preparing two pipe penetrating devices with special lengths and two corresponding teams of workers, namely a pipe penetrating device A and a team A, and a pipe penetrating device B and a team B; s2, the cover plate above the channel is uncovered according to the head-to-tail distance of the total length of the pipe penetrating device to form a skylight, and meanwhile, the cover plate is uncovered in the optical cable laying direction circularly according to the distance; and step S3, the A team and the B team are simultaneously provided with the A pipe penetrating device and the B pipe penetrating device, and the A team enables the head end of the A pipe penetrating device to penetrate from the first skylight and pushes the head end towards the optical cable laying direction. Cyclic relay traction is carried out on the optical cable through the specially-made pipe penetrating device so as to realize uninterrupted continuous laying, the process is rigorous, the division of labor is clear, the working time is reasonably utilized, additional power equipment is not needed, physical activities of workers are more convenient, the working efficiency is higher, the construction cost is lower, and idle work is completely eradicated.

This invention provides a method for assessing and deciding on the feasibility of lead-acid battery repair, relating to the field of lead-acid battery condition assessment technology. The method includes: collecting pre-repair performance indicators of aging batteries and constructing feature variables to quantify the internal aging mechanism of the battery; using the pre-repair state, aging feature variables, and repair operation parameters as inputs, and the post-repair performance as the objective, training a gradient boosting decision tree model that integrates a battery ohmic polarization physical model by introducing a physical constraint term into the loss function; using this model to predict the repair effects of various repair strategies for a specific battery; and combining a threshold to output a repair feasibility conclusion and recommend the optimal repair strategy. This invention solves the problems of traditional lead-acid battery repair assessment relying on experience and having low accuracy, achieving a scientific and quantitative assessment of repair potential and strategy optimization.
