DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. In the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concept of the present invention.

[0016] Specific implementation method: Figure 1-4As shown, a chestnut cleaning machine comprises a trough body 1 with an opening at the top, wherein a spiral blade 3 is rotatably connected in the trough body 1, and the spiral blade 3 is transmission-connected to a reduction motor 5 arranged on the outside of the trough body 1, and a sieve plate 4 with a semicircular cross-section (the central angle of the circle is 180°) is also provided in the trough body 1, and the sieve plate 4 is densely covered with fine sieve holes, and chestnuts will not fall through the sieve holes, and the sieve plate 4 is located below the spiral blade 3 and the two are coaxial, and the two sides of the sieve plate 4 are connected to the inner walls of the two sides of the trough body 1, and the two ends of the sieve plate 4 are connected to the inner walls of the two ends of the trough body 1, and the chestnuts in the trough body 1 can only be located above the sieve plate 4 and not below the sieve plate 4, and a discharge port 13 is provided on one side of the trough body 1, and the discharge port 13 is located above the sieve plate 4, and a plurality of spray pipes 2 are provided above the trough body 1, and a plurality of first water spray holes are provided at the bottom of the spray pipe 2. When in use, combined with Figure 1 As shown, chestnuts are continuously put into the trough body 1 from the left end of the trough body 1, and the spiral blade 3 rotates to transport the chestnuts to the right, and the spray pipe 2 sprays many water jets downward to rinse the chestnuts. In this process, the chestnuts on the sieve plate 4 will be stirred due to the action of the spiral blade 3, and the chestnuts will be turned to the upper layer and turned to the lower layer again many times. The chestnuts themselves will also be turned over many times, so that almost all the chestnuts will be cleaned, and contact friction will occur between the chestnuts, which improves the cleaning effect. The dirty water flows down from the sieve plate 4, so that the water above the sieve plate 4 will not accumulate too much, and the chestnuts will not float. After cleaning, the chestnuts are discharged from the discharge port 13. Since the water above the sieve plate 4 will not accumulate too much, less water flows out of the discharge port 13 (it is best not to set the spray pipe 2 at a position close to the discharge port 13).

[0017] Furthermore, a discharge guide plate 11 is provided below the discharge port 13, and the discharge guide plate 11 gradually tilts downward in the direction from close to to far away from the trough body 1. The chestnuts discharged from the discharge port 13 can slide down along the discharge guide plate 11, and a collection box with small through holes can be placed below the discharge guide plate 11 for collection.

[0018] Furthermore, when the bottom of the trough body 1 is closed, a drain pipe 12 is provided on one side of the lower part of the trough body 1. The drain pipe 12 is located below the sieve plate 4. The drain pipe 12 can be connected to the sewer through a pipeline. The dirty water after flushing can be discharged through the drain pipe 12, so that a lot of water will not accumulate in the trough body 1.

[0019] Furthermore, the spiral blade 3 is provided with a coaxial central shaft 31. The interior of the central shaft 31 is a hollow cavity, and the central shaft 31 is provided with a plurality of secondary water spray holes communicating with the internal cavity. One end of the central shaft 31 is rotatably connected to a rotary joint 6, which is provided with a water inlet pipe 63, which communicates with the internal cavity of the central shaft 31. During use, the water inlet pipe 63 is connected to tap water via a pipe, and the secondary water spray holes can spray water from the interior of the chestnut layer (the upper surface of the chestnut layer is higher than the central shaft 31 and generally slightly lower than the top of the spiral blade 3), thereby improving the cleaning effect and efficiency.

[0020] Specifically, one end of the central shaft 31 is provided with a plurality of water holes 311, and the water holes 311 are connected to the cavity inside the central shaft 31. The rotary joint 6 is coaxial with the central shaft 31 and is sleeved on the outside of the central shaft 31. There is a gap between the rotary joint 6 and the central shaft 31. Two rotating sealing rings 62 are provided in the rotary joint 6, and bearings 61 are provided on the outside of the two rotating sealing rings 62. The rotary sealing rings 62 and the bearings 61 are sleeved on the outside of the central shaft 31. The water hole 311 is located between the two rotating sealing rings 62, and the water inlet pipe 63 is located between the two rotating sealing rings 62. The inner hole of the water inlet pipe 63 passes through the outer wall of the rotary joint 6, so that the water inlet pipe 63 is connected to the water hole 311. A shoulder can be provided near the end of the central shaft 31, with one bearing 61 contacting the shoulder. A retaining ring groove is provided at the end of the central shaft 31, containing a retaining ring. Another bearing 61 contacts the retaining ring. This prevents the rotary joint 6 from moving axially along the central shaft 31, thus achieving a rotational connection with the central shaft 31. To prevent the rotary joint 6 from rotating with the central shaft 31 (which would cause the pipe connected to the water inlet pipe 63 to bend), the water inlet pipe 63 can be fixed to the tank body 1.
