The utility model belongs to the field of pesticide spraying device, concretely is a kind of lotus root planting organic fertilizer pesticide spraying device, the bottom of spraying device is provided with locating plate, the upper portion of locating plate is inserted with antiskid rod, the bottom fixedly connected with locating plate has connecting column, the bottom fixedly connected with connecting column has bearing plate, when the spraying device of connecting column upper portion is moved by bearing plate, the pesticide spraying pipe of spraying device side portion can carry out pesticide application to lotus root pond, and the bottom of bearing plate is in contact with lotus root pond silt ground area, avoid spraying device in the process of moving to sink into silt ground, to reduce work intensity, while the end of bearing plate is provided with pry plate, so that in the process of bearing plate movement, when the protruding soil layer is encountered in moving path, it can also pass smoothly, the stop block can prevent steering rod from continuing to rotate when steering rod is in vertical state, so that the steering rod can be kept in place, and multiple antiskid rods can form a fence to avoid the spraying device from falling during movement.

This invention discloses a rebar straightening device, including a frame, a straightening mechanism mounted on the frame, and a shearing mechanism slidably mounted on the frame. It also includes a discharge mechanism located on the side of the shearing mechanism away from the straightening mechanism. The discharge mechanism includes a first mounting component, a stop component, a discharge component, a discharge drive assembly, and a sliding drive component for driving the stop component to slide. The first mounting component is connected to the shearing mechanism, and the sliding direction of the stop component is the same as the sliding direction of the shearing mechanism. The discharge component is rotatably connected to the bottom of the first mounting component. The discharge drive assembly is located on the first mounting component and connected to the discharge component to drive the discharge component to rotate up and down. In this invention, the discharge drive assembly drives the discharge component to rotate downwards, forming a ramp structure. The cut rebar falls onto the discharge component, while the stop component actively slides and separates from the end of the rebar, releasing the constraint along the length of the rebar. This allows the rebar to roll smoothly off the discharge component, resulting in smooth discharge, reduced accumulation, no need for manual cleaning, and greater convenience.

The utility model relates to the technical field of ring rolling machine, especially a double station ring rolling machine for rolling and expanding metal ring body, which comprises a rack, a sliding seat, a pushing oil cylinder, a rolling mechanism, a rotating motor for driving the rolling mechanism to rotate, a support roller body rotatably arranged on the rack below the rolling mechanism, the support roller body is used for supporting the ring body and realizing rolling and expansion in cooperation with the rolling mechanism, the rack is in an inclined state with an inclination angle of 5-30 degrees to realize independent support of the metal ring body by the support roller body, the support roller body comprises a first roller part close to the rack and a second roller part outside the first roller part, the diameter of the second roller part is smaller than that of the first roller part, and the rolling mechanism comprises a first rolling part matched with the first roller part and a second rolling part matched with the second roller part. The utility model solves the technical problem that the existing ring rolling machine cannot flexibly adapt to the rolling requirements of different parts of the metal ring body.

This application relates to the field of vehicle technology and discloses a seat belt retractor and a vehicle, comprising: a retractor frame, the retractor frame having a mounting hole on one side along a first direction; a reel, a portion of which is rotatably disposed within the retractor frame for winding the seat belt, the reel extending along the first direction and passing through the mounting hole, the outer peripheral wall of the reel being spaced apart from the wall of the mounting hole; and a cover plate covering the mounting hole for shielding the mounting hole, the end of the cover plate facing the inner side of the retractor frame having a protrusion disposed between the reel and the wall of the mounting hole, the protrusion being spaced apart from the reel. The seat belt retractor provided by this application allows the protrusion to fill the gap between the reel and the wall of the mounting hole, thereby preventing the seat belt from getting stuck in the gap between the reel and the wall of the mounting hole, ensuring smooth seat belt retraction.
