[0002] Mobile grain conveyor is a kind of pneumatic conveying equipment for bulk particles that is currently being vigorously promoted by the domestic grain industry. It is widely used in docks, warehouses, grain processing plants and other places. The conveying objects include wheat, rice, corn, rapeseed and other granular materials.

[0003] like Figure 1 As shown, the suction nozzle of existing grain scoops is typically a rigid structure, mounted at the front end of the scoop arm. It can move forward, backward, left, right, and up and down with the scoop arm, completing grain scooping within a certain range. However, due to: 1) the limited range of motion of the scoop arm; and 2) in some cases, spatial constraints in the operating environment, such as in the corners of a warehouse or the bottom of a ship's cabin, these rigid suction nozzles cannot be moved to the scoop position, creating a dead zone. Summary of the Invention

[0004] The purpose of the utility model is to provide a suction nozzle device of a mobile trolley of a grain sucking machine, which can effectively solve the above problems and expand the operating range of the grain sucking machine.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0007] A handwheel is set at the rear of the frame, and the handwheel is connected to one end of the rocker forward. The other end of the rocker is connected to the angle adjustment shaft through a threaded pair. The angle adjustment shaft is connected to the shaft sleeve of the movable supporting wheel bracket. The movable supporting wheel is pressed against the suction pipe on the movable supporting wheel bracket. The front end of the suction pipe is connected to the suction nozzle, so that the suction nozzle can be adjusted up and down.

[0008] Furthermore, the suction nozzle is a square-to-circle suction nozzle, the rear end is circular, and the front end is rectangular. Furthermore, the rear end of the suction pipe is connected to a hose, and the hose is connected to the grain suction arm of the grain suction machine.

[0009] Furthermore, the hose is connected to the grain suction arm of the grain suction machine by using a quick clamp.

[0010] Furthermore, the suction pipe rotates around the angle adjustment axis to adjust the suction nozzle up and down.

[0011] Furthermore, the rocker is configured as a threaded rod.

[0012] Furthermore, the directional wheel is mounted on the front bottom of the frame via a caster mounting bracket.

[0013] Furthermore, an armrest bracket is welded to the vehicle frame, and an armrest is welded to the armrest bracket.

[0014] The advantages of this utility model are as follows:

[0015] (1) The utility model solves the problem that the existing grain sucking machine cannot fully cover the working range in some situations and therefore cannot suck all the grain in the working place, and needs to use other equipment or manual cleaning to clean up the remaining grain.

[0016] (2) The utility model of the mobile trolley suction nozzle device of the grain suction machine expands the operating range and space of the grain suction machine, and solves the problem that the existing grain suction machine cannot completely suck all the grain in the operating area and needs subsequent cleaning.

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] In general, mobile grain suckers use rigid suction nozzles for operation (such as Figure 1 In the working area where the rigid suction nozzle cannot reach, the rigid suction nozzle is removed and the suction nozzle device of the mobile trolley of the grain suction machine of this embodiment is connected to operate (as shown in FIG. Figure 2 shown).

[0030] Preferably, the above-mentioned rigid suction nozzle and the suction nozzle device of the mobile trolley of the grain suction machine in this embodiment are connected to the grain suction arm by a quick clamp, which is convenient for disassembly and assembly, and has a reliable connection and no air leakage.

[0031] The suction nozzle device of the mobile trolley of the grain suction machine in this embodiment is connected to the grain suction arm through a hose.

[0032] Reference Figures 3 to 8 As shown, the suction nozzle device of the mobile trolley of the grain suction machine of this embodiment includes a suction pipe 1, an armrest bracket 2, an armrest 3, a movable supporting wheel bracket 4, a handwheel 5, a universal wheel 6, a fixed wheel 7, an angle adjustment shaft 8, a caster mounting bracket 9, a rocker 10, a square-to-circular suction nozzle 11 and a frame 12;

[0033] Among them, handrail brackets 2 are erected on both sides of the frame 12, and the frame 12 and the handrail bracket 2 are welded to each other to form a rigid structure. Handrails 3 are provided on the handrail bracket 2 to facilitate operation by the staff.

[0034] A fixed wheel 7 is installed in the front bottom of the frame 12 (specifically, the fixed wheel 7 is installed in the front bottom of the frame 12 through a caster mounting bracket 9), and a universal wheel 6 is installed in the rear bottom of the frame 12. The operator controls the armrest 3 to move the suction nozzle device of the mobile trolley of the grain sucking machine of this embodiment forward, backward, left and right.

[0035] like Figure 9 As shown, a handwheel 5 is provided at the rear of the vehicle frame 12, and the handwheel 5 is connected to one end of the rocker 10 forward, and the other end of the rocker 10 is connected to the angle adjustment shaft 8 through a threaded pair (the rocker 10 is a threaded rod and is an external thread, and the angle adjustment shaft 8 is an internal thread), and the angle adjustment shaft 8 is connected to the shaft sleeve of the movable supporting wheel bracket 4, and a movable supporting wheel 41 is provided on the movable supporting wheel bracket 4, and a suction pipe 1 is provided above the movable supporting wheel 41.
