As shown in fig. 4, 5 and 3, a main chamber 10 is formed at the lower part of the vehicle body 1, a rotary impeller 2 is mounted in the main chamber 10, the rotary impeller 2 is provided with three blades 21, and the rotary impeller 2 and the travelling wheel 13 share the same rotary shaft 20 to synchronously rotate; the front lower part of the main chamber 10 is provided with a ball inlet 31, and the ball inlet 31 is positioned at the front lower part of the rotary impeller 2; a ball guide cavity channel 11 is also communicated above the main cavity 10 of the vehicle body, and a ball outlet 32 is arranged at the upper part of the ball guide cavity channel 11; the ball outlet 32 faces forward, and a ball guide cavity arc turning section 110 is arranged between the lower section of the ball guide cavity 11 and the ball outlet 32; the lower end of the ball guide cavity channel 11 is positioned above the rear part of the rotary impeller 2, and a first guide roller 41 is arranged on the front side of the lower end of the ball guide cavity channel 11; the central axis of the first guide roller 41 is parallel to the central axis of the travelling wheel rotating shaft 20, the distance between the first guide roller 41 and the rear wall 5 at the lower end of the ball guiding cavity is equal to 0.93 times of the diameter of the ball, namely, the diameter of the ball is slightly smaller than the diameter of the ball (the diameter of the ball in a natural state without being extruded and elastic deformation), a bayonet 30 is formed between the first guide roller 41 and the rear wall 5 at the lower end of the ball guiding cavity, and the bayonet 30 can prevent the ball in the ball guiding cavity 11 from falling down into the main cavity 10 of the vehicle body, so the bayonet is named as a bayonet; the distance between the first guide roller 41 and the traveling wheel spindle 20 (i.e., the AQ distance in fig. 5) corresponds to 0.75 times the diameter of the ball. The front side of the lower end of the ball guide cavity 11 is also provided with a second guide roller 42, the second guide roller 42 is positioned above the first guide roller 41, the second guide roller 42 is parallel to the first guide roller 41, and the distance between the second guide roller 42 and the rear wall 5 of the lower end of the ball guide cavity is equivalent to 0.93 times of the diameter of a rolling ball and is slightly smaller than the diameter of the rolling ball.
As shown in fig. 5, each blade 21 of the rotary impeller comprises a proximal section close to the rotary shaft 20, such as AB section/GH section/DE section in fig. 3, and a distal section far from the rotary shaft 20, such as BC section/EF section/HK section in fig. 3, made of a rigid material, and made of an elastic plastic material, and the distance between the end of the proximal section (such as point B/H/E in fig. 3) and the central axis of the rotary impeller 2 is smaller than the distance between the first guide roller 41 and the central axis of the rotary impeller; the distance between the distal end of the telecentric section (point C/point F/point K in fig. 3) and the central axis of the rotating impeller 2 (refers to the distance in the natural state in which the telecentric section is not pressed by an external force; if the telecentric section is beside the first guide roller 41, the telecentric section is pressed to deform, and the distance between the distal end of the telecentric section and the central axis of the rotating impeller 2 is temporarily shortened, so that the distance after deformation is not referred to as the distance after deformation) is greater than the distance between the first guide roller 41 and the central axis of the rotating impeller 2.
The principle of use of the above embodiment is as follows: during playing, a plurality of rolling balls (rolling balls 81 and 82, rolling balls 83 and the like) can be placed on the ground, when a child pushes the toy barrow to advance on the ground (the moving direction is shown by arrows in fig. 6 and 7), the travelling wheel 13 drives the rotary impeller 2 to synchronously rotate, when the ball inlet 31 of the toy barrow is aligned with the rolling balls 81 on the ground and continues to push the toy barrow to advance, as shown in fig. 6, the rolling balls 81 enter the main chamber 110 through the ball inlet 31, as shown in fig. 7, and then are pushed by the blades 21 of the rotary impeller to move towards the rear upper part of the main chamber 10, as shown in fig. 8, at the moment, the highest point of the rolling balls 81 is higher than the first guide roller 41, so that the first guide roller 41 forms a part for preventing the rolling balls 81 from moving forwards, the rolling balls 81 can only move upwards, and then the rolling balls 81 can be pushed upwards by the blades 21 of the rotary impeller to pass through the bayonet 30; when passing through the bayonet 30, the ball 81 is elastically deformed by the pressing, slightly flattened, and the ball 81 slightly passing over the bayonet 30 is slightly restored to its natural shape by the elasticity, and the front end portion of the ball 81 is caught between the first guide roller 41 and the second guide roller 42, as shown in fig. 9, and the ball 81 in the ball guide passage cannot return downward to the main chamber 10 because the ball 81 is not subjected to a strong downward pressure. Therefore, when a subsequent additional ball 82 is rolled into the main chamber 10 and pushed up through the bayonet 30 to enter the ball guide channel 11, the previous ball 81 will be pushed up by the subsequent ball 82 and forced to move towards the ball outlet 32, and finally be ejected from the ball outlet 32 of the ball guide channel, as shown in fig. 10, the subsequent ball 82 will be temporarily clamped between the first guide roller 41 and the second guide roller 42 until the subsequent ball 83 is rolled up and lifted up, so that the subsequent ball pushes the front ball, i.e. the rear ball is continuously swallowed from the ball inlet 31, the front ball is continuously spitted from the ball outlet 32 to drop to the ground, and the rear ball is again used as a target to be chased. Thus, the cycle is continuously carried out, and the interestingness of the travelling process of the trolley is increased.
In the above embodiment, the distance between the first guide roller 41 and the rotation shaft of the traveling wheel 2 may be changed to be equivalent to 0.84 times the diameter of the ball, or 0.70 times the diameter of the ball.
In the above embodiment, the distance between the first guide roller 41 and the rear wall 5 at the lower end of the ball guide channel may instead be 0.90 times the diameter of the ball, or 0.97 times the diameter of the ball, as long as the distance is slightly smaller than the diameter of the ball, so that the ball cannot push down through the bayonet 30 under the action of gravity, but can push up through the bayonet 30 under the pushing of the rotating impeller blades 21.
Likewise, the distance between the second guide roller 42 and the rear wall 5 at the lower end of the ball guide channel may instead correspond to 0.90 times the diameter of the ball, or 0.97 times.
