[0028] Please refer to Figs. 1 to 4 The first embodiment of the utility model provides a sand box 4 sand cleaning machine, which comprises:

[0029] The rack is a support structure of the whole device, which is welded by high-strength steel;

[0030] The roller conveying mechanism 1 is arranged on the rack and comprises a plurality of roller shafts 11, the end portions of the roller shafts 11 are rotatably connected to the rack through bearings, and rollers 12 are intermittently arranged on the roller shafts 11; the rollers arranged on adjacent roller shafts are consistent, which ensures the stable conveying of the sand box; and there is sufficient gap between adjacent rollers for the lifting of the lower nozzle.

[0031] The upper cover 2 comprises an outer frame 21, which is erected above the roller conveying mechanism 1 through a support; a metal sheet or a waterproof cloth is additionally arranged on the outer frame 21 to form the upper cover 2; when the sand box 4 reaches the upper cover covering position a, the sand box is washed, so that the sewage generated by the washing is shielded by the upper cover and cannot splash around.

[0032] The upper spraying system is located in the upper cover 2, comprising a connecting frame 22, the connecting frame 22 is installed in the outer frame 21, a plurality of nozzle deflector plates are arranged in the connecting frame 22, the two ends of the nozzle deflector plate are also rotatably connected with the connecting frame 22 through bearings, and each upper nozzle 23 is uniformly distributed on the nozzle deflector plate and can perform high-pressure flushing downward; each nozzle deflector plate is driven to rotate by an additional gear mechanism, so that the upper nozzle can swing left and right, and the box blocking part of the sand box can be better flushed;

[0033] The lower spraying system 3 comprises a lifting mechanism 31 arranged below the roller conveying mechanism 1 and corresponding to the position of the upper cover 2, and the driving end of the lifting mechanism 31 is upwardly arranged with a lifting frame 32, the lifting frame 32 has a plurality of horizontal rods arranged therein, a plurality of vertical rods 33 are arranged on the horizontal rods, the positions of the vertical rods 33 correspond to the gaps between adjacent rollers, and a rotary air cylinder is further arranged at the top end of the vertical rod 33, and the driving end of the rotary air cylinder is arranged with a lower nozzle 34, so as to increase the flushing area and effect by lifting and rotating the lower nozzle;

[0034] The water collecting system is located below the lower spraying system 3, comprising a water collecting tank, a primary filter screen and a secondary filter screen arranged in the water collecting tank, and the primary and secondary filter screens are regularly cleaned and replaced.

[0035] Specifically, the roller conveying mechanism 1 uses an alternating current motor as a power source, and uses chain transmission to drive each roller shaft 11, so as to reduce the load of the motor and improve the stability and reliability of transmission.

[0036] Specifically, the lifting mechanism 31 uses a hydraulic cylinder, and a reverse V-shaped baffle is further arranged at the driving end of the lifting mechanism 31 for shielding the water flow during flushing.

[0039] In order to reduce water splashing during flushing, the covering position a of the upper cover is greater than the sand box to be flushed:

[0040] When a metal sheet is used as the material of the upper cover, the lower edge of the metal sheet is higher than the sand box to avoid scratching;

[0041] When a waterproof cloth is used as the material of the upper cover, the waterproof cloth can be slightly longer, when the sand box enters the covering range of the waterproof cloth and triggers the sensor, the conveying stops and the flushing starts.

[0042] The flushing strategy of the sand cleaning machine is divided into three stages of pre-flushing, key-flushing and overall-flushing:

[0043] 1. Pre-rinsing is a preliminary rinsing of the sand box by a rotating nozzle driven by a lifting mechanism, which removes most of the loose impurities;

[0044] 2. Focused rinsing: The upper nozzle is used for oscillating rinsing, targeting the baffle of the sand box;

[0045] 3. Thorough Rinse: Activate the upper and lower spray systems simultaneously to ensure that all parts of the sandbox are thoroughly cleaned.

[0046] The beneficial effects of this utility model of a sand box cleaning machine are:

[0047] 1. The lower spray system is designed with a liftable lower spray head structure, which works in conjunction with the roller conveyor mechanism and the upper spray head structure to wash the sand box.
