a rear water guide cavity communicated with the front water guide cavity is formed in the counterweight plate;

when stone is put into the stone throwing port, the stone presses the splash plate to turn over and the counterweight plate is tilted upwards to open the stone throwing port, so that the stone slides into the stone crusher from the inclined splash plate;

when the splash guard is empty, the counterweight plate is tilted downwards until the bottom of the feeding funnel blocks the splash guard, so that the splash guard blocks the stone throwing port, and the splash guard blocks broken stones in the stone crusher from splashing out of the stone throwing port;

when the rainwater falls onto the splash guard from the stone throwing port, the rainwater flows out through the front water guide cavity and the rear water guide cavity under the guidance of the splash guard component, and the splash guard component absorbs the rainwater to form a dust blocking layer so as to prevent flying dust in the stone crusher or buffer broken stones.

2. The asphalt mixture delivery apparatus of claim 1,

the rainwater detection module includes: the rainfall sensor is electrically connected with the control module;

the rainfall sensor is positioned at the stone throwing port;

the rainfall sensor collects rainfall data at the stone throwing port and sends the rainfall data to the control module;

and the control module controls the stone breaking mechanism to stop working when the rainfall data at the stone throwing port exceeds the rainfall set value.

3. The asphalt mixture delivery apparatus of claim 1,

the current detection module includes: a current sensor;

the control module detects current information of the motor through a current sensor.

4. The asphalt mixture delivery apparatus of claim 3 wherein,

the rotation speed detection module includes: a rotation speed sensor;

the control module detects rotational speed information of the motor through a rotational speed sensor.

5. The asphalt mixture delivery apparatus of claim 4,

the control module drives the scale factor regulator, the trigger circuit and the soft start circuit to drive the motor to start in frequency division according to the current information and the rotating speed information of the motor until the motor is stable.

6. The asphalt mixture delivery apparatus of claim 1,

the splash guard assembly includes: the water sucking device comprises a C-shaped frame, a water sucking unit and a baffle plate;

corresponding moving grooves are formed in two ends of the C-shaped frame respectively, the C-shaped frame is movably arranged in the front water guide cavity through two sliding columns, sliding springs are sleeved on the sliding columns, the sliding columns are movably inserted into the corresponding moving grooves, the water absorbing unit is located on the inner side of the C-shaped frame, and the baffle is longitudinally arranged on the beam part of the C-shaped frame;

the C-shaped frame and the baffle are propped against the inner side wall of the feeding funnel through the sliding column and the sliding spring;

rainwater flows into the C-shaped frame and the water absorption unit from the splash guard, the baffle blocks the rainwater from flowing into the stone crusher from the C-shaped frame, the C-shaped frame and the water absorption unit guide the rainwater to flow out through the front water guide cavity and the rear water guide cavity, and the water absorption unit absorbs the rainwater to form a dust blocking layer.

7. The asphalt mixture delivery apparatus of claim 6,

the bottoms of the C-shaped frame and the water absorbing unit are provided with a plurality of guide strips;

when the counterweight plate and the splash shield are turned reciprocally, the C-shaped frame and the water absorbing unit stretch reciprocally under the action of the sliding column and the sliding spring, dust or broken stones in the stone crusher enter the front water guide cavity and are positioned between the C-shaped frame and the water absorbing unit and the guide strips, the C-shaped frame and the water absorbing unit drive the dust or the broken stones to move towards the rear water guide cavity, and the guide strips block the dust or the broken stones from retreating until the dust or the broken stones enter the rear water guide cavity and slide out.

8. A production process employing the apparatus for producing an asphalt mixture conveying as defined in any one of claims 1 to 7, comprising:

the control module detects rainfall data at the stone throwing port through the rainwater detection module so as to control the on-off of the stone breaking mechanism;

after the broken stone mechanism is started, the control module respectively detects current information and rotation speed information of the broken stone mechanism through the current detection module and the rotation speed detection module so as to drive the broken stone mechanism to start in a frequency division mode until the broken stone mechanism is stable;

when stone is put into the stone throwing port, the stone pressing and splashing preventing mechanism turns over to open the stone throwing port so that the stone enters the stone crushing mechanism;

when the anti-splashing mechanism is empty, the anti-splashing mechanism blocks the stone throwing port so as to prevent broken stones in the stone breaking mechanism from splashing out of the stone throwing port; and

the splash-proof mechanism guides rainwater to flow out from the stone throwing port, and absorbs the rainwater to form a dust blocking layer so as to prevent flying dust in the stone breaking mechanism or buffer broken stones.
