The force hammer shifting rod is located below the hammer rod, the elastic element is connected with the hammer rod, the driving device is used for driving the force hammer shifting rod to move upwards or downwards, the force hammer shifting rod can drive the hammer rod to move upwards or downwards while moving upwards or downwards, and the force sensor is used for measuring and feeding back force value signals. The utility model has the beneficial effects that: 1, a complex angle adjusting mechanism is cancelled, the knocking position precision is ensured by fixing the mechanical bracket, and the mechanical interference is avoided; and 2, by simplifying the structural design and optimizing the control mode, the knocking force and the knocking position are automatically adjusted, and meanwhile, the equipment cost is reduced.

The present application relates to the technical field of pre-embedded part positioning device, in particular to a pile foundation pre-embedded part positioning device for mountain photovoltaic engineering, which comprises a positioning cylinder, the bottom end of the positioning cylinder is rotatably installed with three outer sheaths which are annularly and uniformly distributed, the inner part of each outer sheath is provided with an inner sheath, the distal end of each inner sheath and outer sheath is provided with a movable ski for increasing the pressure bearing area, the lower side of the positioning cylinder is provided with a matching sleeve, the matching sleeve is located inside the enclosed position of the three outer sheaths, the inner part of the outer sheath is provided with an auxiliary embedding device, the energy transmission structure formed between the matching sleeve and the response sleeve cooperates with the reset torsional spring and the power hammer, which can provide additional driving force when inserting the positioning sign, and the depth insertion of the reference pile can be completed without the traditional external force knocking, so that the construction personnel can complete the positioning and placement of the pre-embedded part under the condition of single-person operation, improve the initial reference construction efficiency of the pile foundation, and improve the accuracy and reliability of the pile foundation installation as a whole, which is especially suitable for the pile foundation positioning construction scene in mountain photovoltaic engineering.

This utility model proposes a weighing and monitoring system for pile foundation construction fill material, belonging to the technical field of driven stone pile drivers. This utility model achieves accurate acquisition of the amount of crushed stone filled during construction by weighing and accumulating the weight of the fill material in the concrete hopper each time. The technical solution includes a pile driver mast, a pile pipe, and a concrete hopper. A power hammer is fixed to the top of the pile pipe, and a first sliding wheel is provided on one side of the power hammer. A track is provided on the side of the pile driver mast opposite to the pile pipe, and the track cooperates with the first sliding wheel. A crossbeam is provided at the top of the pile driver mast, and a first pulley block is provided on the crossbeam. The power end of the first pulley block is connected to a first winch, and its resistance end is connected to a weighing device. The weighing device has a hook, which is connected to a fixed frame. The concrete hopper is fixed on the fixed frame, and the weighing device is used to weigh the weight of the fill material in the concrete hopper.

The utility model discloses a low-power-consumption hammer type feed grinder which comprises a base and a blanking interception assembly, a processing unit is arranged at the top of the base, and a driving part is arranged on the side of the processing unit and located at the top of the base; the discharging interception assembly comprises a clamping base arranged on the inner wall of the discharging port of the machining unit, the top of the clamping base is connected with a blocking part used for sealing the discharging port of the machining unit in a penetrating mode, and a locking part used for fixing the position of the blocking part is arranged at the penetrating position of the blocking part and the clamping base. The blanking interception assembly is arranged at the discharging position of the processing unit, the blocking part penetrating through the clamping seat in the blanking interception assembly is used for blanking and stopping crushed feed, and the locking part is used for limiting the blocking part, so that compared with direct blanking after the feed is crushed by the processing unit, the blanking interception assembly is simple in structure and convenient to use. According to the design, smashed and splashed feed can be conveniently received through the blocking part, kinetic energy of the splashed feed is consumed, and it is avoided that follow-up receiving operation is affected by splashing and falling of the feed.
