DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] As Figures 1-5In it, a fruit diameter screening device for pitayas includes a frame body 1. A bottom plate 301 is provided on the frame body 1. A plurality of vertical plates 302 are arranged in parallel and at intervals on the bottom plate 301. A second through-channel 3 is provided between adjacent vertical plates 302. The second through-channel 3 is arranged obliquely. A hollow part 305 is provided at the bottom end of each second through-channel 3. Two guiding rods 4 arranged in a V-shaped pattern are provided at each hollow part 305. A collecting rack 6 is provided below the second through-channel 3 on the frame body 1. A plurality of partition boxes 601 are arranged along the length direction of the collecting rack 6; A second spring 309 is also connected between the bottom plate 301 and the frame body 1. A second vibration motor 310 is connected to the lower end of the bottom plate 301.

[0018] There can be multiple second through-channels 3. The pitayas roll from the higher end to the lower end of the second through-channel 3. Since the two guiding rods 4 are arranged in an involute shape, the distance at the higher end is narrower. When the smaller pitayas roll down, they fall into the partition boxes 601 of the collecting rack 6 below. The larger ones continue to roll until the distance between the guiding rods 4 is greater than the diameter and they fall into the next partition box 601.

[0019] Since there are leaves on the outer skin of the pitayas, the rolling resistance is increased, and the slopes of 2 and 3 need to be set steeper.

[0020] In addition, if there are relatively oval-shaped pitayas in the batch, it is necessary to turn on the second vibration motor 310. At this time, the narrow side of the oval-shaped pitaya will get stuck between the two guiding rods 4 and gradually slide down along the guiding rods 4 with the assistance of high-frequency vibration.

[0021] In a preferred solution, elevation plates 306 are provided at both lower ends of the second through-channel 3. The guiding rod 4 includes a rod body 401. A hollow channel 403 is provided between the two rod bodies 401. One end of the rod body 401 is hinged to the elevation plate 306 at one end of the second through-channel 3. An arc-shaped hollow groove 307 is provided on the elevation plate 306 at the other end of the second through-channel 3. The other end of the rod body 401 is stuck in the arc-shaped hollow groove 307 and swings. A first locking screw 308 is provided at the end of the rod body 401 in a threaded connection. The first locking screw 308 presses against the elevation plate 306 to lock the angle of the rod body 401.

[0022] The arc-shaped hollow groove 307 is centered on the hinge point of the other end of the rod body 401. Loosen the first locking screw 308, and the involute angle of the rod body 401 can be adjusted. If the overall size of the pitaya batch varies greatly, the V-shaped angle can be increased. If the overall size of the pitaya batch varies little, then adjust the rod body 401 to be more parallel.

[0023] In a preferred embodiment, the rod body 401 is provided with a through groove 404. An adjusting tongue 402 is arranged in the through groove 404. One side of the adjusting tongue 402 close to the hollow channel 403 extends out. A second locking screw 405 connected by threads is arranged on the side wall of the through groove 404. One end of the second locking screw 405 abuts against the side wall of the adjusting tongue 402.

[0024] By loosening the second locking screw 405, the lateral extension amount of the adjusting tongue 402 can be adjusted to increase or decrease the width of the hollow channel 403. If the overall size of the pitaya batch is relatively large, the hollow channel 403 is widened. If the overall size of the pitaya batch is relatively small, the hollow channel 403 is narrowed.

[0025] In a preferred embodiment, a channel baffle 303 is further arranged on one side of each vertical plate 302 close to the second through channel 3. One end of the channel baffle 303 is provided with a guide rod 304 slidably sleeved on the vertical plate 302. The distance between adjacent channel baffles 303 is adjustable.

[0026] The guide rod 304 is a screw rod. At least two nuts are sleeved on the guide rod 304, and the vertical plate 302 can be clamped to lock the position of the channel baffle 303. According to the included angle of the rod body 401 and the width of the hollow channel 403, the distance between the channel baffles 303 can be changed. For example, when the distance between the hollow channels 403 decreases, the distance between the channel baffles 303 also decreases, ensuring that the pitayas roll downward from the area of the hollow channels 403.

[0027] In a preferred embodiment, a first through channel 2 is further arranged on the frame body 1. A sieve plate 201 is arranged in the first through channel 2. The sieve plate 201 is arranged obliquely. The lower end of the sieve plate 201 is close to the higher end of the second through channel 3. The sieve plate 201 is provided with a plurality of filter holes 204. A collection box 5 is arranged below the sieve plate 201. A first spring 202 is connected between the lower end of the first through channel 2 and the frame body 1. A first vibration motor 203 is further connected to the lower end of the first through channel 2.

[0028] When the first vibration motor 203 vibrates, the first through channel 2 vibrates as a whole. The pitayas first pass through the first through channel 2 and roll downward along with the vibration. The soil, dust particles, etc. on the pitayas are screened and fall into the collection box 5, improving the cleanliness and preventing a large amount of dust from being brought into the separation box 601 and affecting the subsequent process.

[0029] The above embodiments are only the preferred technical solutions of the present invention and should not be regarded as limitations on the present invention. The protection scope of the present invention should be the technical solutions recorded in the claims, including the equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, the equivalent replacement improvements within this scope are also within the protection scope of the present invention.
