Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0030] Example

[0031] like Figure 1-5 As shown, a high-efficiency sand washing machine for machine-made sand production includes a machine body 1, characterized in that: a discharge port 11 is provided on one side of the machine body 1, and a sand and gravel feeding device 2 is provided on the other side, and two ports are provided at the bottom of the sand and gravel feeding device 2, namely a discharge port 22 and a fine sand port 25, and the discharge port 22 is connected with the cleaning inner cavity of the machine body 1, and a fine sand collecting bin 3 is provided at the bottom of the sand and gravel feeding device 2, and an anti-clogging discharge tray 21 and a fine sand filter seat 23 are provided inside the sand and gravel feeding device 2 and are in an upper and lower structure; the above technical scheme can orderly introduce the poured sand and gravel into the inner cavity of the sand washing machine to prevent blockage, so that the impeller of the sand washing machine is not restricted in stirring, and the efficiency of sand washing is improved. At the same time, before the sand and gravel are introduced, the sand and gravel can be filtered to filter out the fine sand, so as to facilitate the direct recovery of fine sand.

[0032] In this embodiment, a driving motor is installed on one side of the anti-clogging discharge tray 21, and at least one open discharge bin port 212 is evenly arranged inside, a closed material bin 211 is arranged between the discharge bin port 212 and the discharge bin port 212, and a guide port 213 is arranged at the bottom of the anti-clogging discharge tray 21. The above-mentioned driving motor drives the anti-clogging discharge tray 21 to rotate, thereby transporting sand and gravel, wherein the discharge bin port 212 is used to store the poured sand and gravel.

[0033] In this embodiment, the feed bin opening 212 is of a structure that is wide at the top and narrow at the bottom. When the anti-clogging feed disc 21 rotates, when the feed bin opening 212 rotates to the guide opening 213, its top opening is downward and fits with the guide opening 213. The rotation of the anti-clogging feed disc 21 causes the feed bin opening 212 to rotate, and the sand and gravel are transferred to the guide opening 213, and are introduced from the guide opening 213 into the fine sand filter seat 23 for filtration.

[0034] In this embodiment, the swing filter seat 26 includes a column 261, a movable swing rod 262, a filter seat 263, a swing mechanism 264, and a driving motor 265. The driving motor 265 is meshed and transmission-connected with the swing mechanism 264. The column 261 is fixed on the surface wall of the swing filter seat 26. The top rotating shaft of the movable swing rod 262 is movably connected with the inner groove on the surface of the column 261. The middle end is movably connected with the inner groove on the surface of the swing rod of the swing mechanism 264 through a connecting rod through a rotating shaft, and the bottom end is fixedly connected to the back of the filter seat 263. Excretion ports 2631 are provided on both sides of the filter seat 263. The swing mechanism 264 can be driven to rotate by the driving motor 265, and the movable swing rod 262 will be driven to rotate at the same time. Since the upper and lower ends of the movable swing rod 262 are movably connected through the rotating shaft, the movable swing rod 262 will drive the filter seat 263 to swing, thereby dispersing the sand and preventing it from piling up when falling and affecting the filtering effect.

[0035] In this embodiment, a vibration motor 24 is installed on the surface wall of the sand and gravel feeding device 2, the surface of the fine sand filter seat 23 is set to a detachable fine sand filter screen, and a first spring group 231 is installed at the bottom. The vibration of the vibration motor 24 is used to filter the fine sand filter screen to filter out the fine sand first for easy recovery.

[0036] In this embodiment, the fine sand filter seat 23 is inclined, with its right side arranged at the lower end, and it passes through the discharge port 22 and is embedded in the cleaning inner cavity of the machine body 1. The above-mentioned gravity can discharge the sand and gravel filtered on the fine sand filter net from the discharge port 22 and finally enter the cleaning inner cavity of the machine body 1.

[0037] In this embodiment, a spring vibration seat 31 is connected to the top of the fine sand collection bin 3, and a second spring group 32 is arranged between the plates of the spring vibration seat 31. A notch 33 is arranged in the middle of the spring vibration seat 31. The above is used in conjunction with the vibration motor 24. When vibrating, the second spring group 32 and the first spring group 231 will vibrate at the same time, thereby facilitating filtering of fine sand from the filter net.

[0038] In this embodiment, the notch 33, the fine sand port 25, and the top port of the fine sand collecting bin 3 are all on the same vertical line. The filtered fine sand can be dropped from the fine sand port 25, the notch 33, and the fine sand collecting bin 3 in sequence, and finally collected into the fine sand collecting bin 3.

[0039] Working principle:

[0040] First, pour the sand and gravel into the sand and gravel feeding device, then the anti-clogging discharge tray 21 of the driving motor is started and starts to rotate. While rotating, the sand and gravel will fall into the discharge bin port 212 for orderly collection and rotation. The speed of the driving motor can be set according to demand. The sand and gravel will be transported to the guide port 213 and then fall into the swing filter seat 26. At this time, the swing mechanism 264 is driven by the driving motor 265 to rotate, and the movable swing rod 262 is driven to rotate at the same time. Since the upper and lower ends of the movable swing rod 262 are movably connected by a rotating shaft, the movable swing rod 262 will drive the filter seat 263 to swing, thereby dispersing the sand and preventing it from piling up when falling and affecting the process. The filtration effect is achieved, and the dispersed sand falls into the fine sand filter seat 23 for filtration. At this time, the vibration of the vibration motor 24 will filter the fine sand, and the filtered fine sand will fall from the fine sand port 25, the slot 33, and the fine sand collecting bin 3 in turn, and finally be collected in the fine sand collecting bin 3. On the other hand, the sand and gravel that cannot be filtered will fall to the discharge port 22, and finally enter the inner cavity of the machine body 1 for sand washing; the design is provided with an anti-blocking discharge tray 21, which can be driven by a driving motor to rotate the anti-blocking discharge tray 21, so that the discharge bin port 212 and the closed bin 211 are alternated in sequence, thereby orderly transporting the sand and gravel to the inner cavity of the sand washing machine to prevent the inner cavity of the sand washing machine from being blocked; on the other hand, a fine sand filter seat 23 is provided, which can filter the fine sand for easy recovery.
