Description

Technical Field

[0001] The utility model relates to the technical field of screening machines, in particular to a raw material screening machine for nut processing. Background Art

[0002] Nuts are a type of closed fruit with a hard peel and one or more seeds inside. Such as chestnuts, almonds, etc. Nuts are the essence of plants and are generally rich in nutrients. They contain high levels of protein, oil, minerals, and vitamins. They are very effective in promoting human growth and development, strengthening physical fitness, and preventing diseases. Nuts need to be screened because of their different sizes, so a screening device is needed.

[0003] A Chinese patent discloses a raw material screening machine for nut processing (application number: 202321285910.X). This scheme uses a first screen bin and a second screen bin installed on a mounting plate to vibrate so that nuts of different particle sizes fall into different receiving bins. The receiving bin can tilt the discharge door by pulling down the handle, so that the nuts in the receiving bin can be discharged faster. Before the nut raw materials are screened, the fruit will be mixed with shell debris, dust, sand and gravel and other debris, and these debris are very small and will fall directly into the receiving bin through the sieve holes of the sieve. After the nuts are screened, they need to be manually screened for a second time to separate them from the nuts, which increases the manual workload, makes the screening process more cumbersome, and reduces work efficiency. At the same time, manual contact with nuts will also cause pollution, which will affect the quality of the nuts and the benefits. On the other hand, the device only uses a vibrator to screen the nuts, and cannot separate the nuts of different sizes well. The nuts are easily stuck in the sieve holes of the sieve, affecting the screening work. When discharging the materials, the discharge door still needs to be opened manually to collect the materials, which is inefficient, easy to cause pollution, and not very practical.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-8 The utility model provides a technical solution of a raw material screening machine for nut processing. The utility model will be further introduced in detail below in conjunction with the accompanying drawings.

[0028] Embodiment 1:

[0029] A raw material screening machine for nut processing comprises a box body 1, a mounting frame 12 and a sieve plate 13. A group of connecting rods 2 are fixedly connected to the inner cavity of the box body 1, and a separation plate 3 is fixedly connected to the outside of the connecting rods 2. A collecting frame 4 is fixedly connected to one side of the inner cavity of the box body 1 below the separation plate 3, a dust collecting box 5 is slidably connected inside the collecting frame 4, and a baffle 6 is fixedly connected to one side wall of the collecting frame 4. A feeding hopper 10 is fixedly connected to the top of the box body 1, and a feeding pipe 11 is fixedly connected to the top of the feeding hopper 10. The feeding pipe 11 extends to the inner cavity of the box body 1 and is located above the right side of the separation plate 3. An air pump 7 is arranged at one end of the top of the box body 1 away from the feeding hopper 10, and an air outlet pipe 8 is fixedly connected to the output end of the air pump 7, and an exhaust square pipe 9 is fixedly connected to the other end of the exhaust square pipe 8. The exhaust square pipe 9 is arranged on the inner wall of the box body 1, and a protective net 34 is arranged at one end of the exhaust square pipe 9. The baffle 6 can prevent impurities from falling into the interior of the box body 1 from the gap, and the protective net 34 can also prevent nuts from splashing into the interior of the exhaust square pipe 9 during the falling process, so that the exhaust square pipe 9 can operate normally.

[0030] When used specifically, Figure 1 , Figure 2 and Figure 3 , Figure 4As shown, the nut raw material is put into the feeding hopper 10, and falls on one side of the separation plate 3 through the feeding pipe 11, and at the same time, the air pump 7 is turned on to inject high-pressure gas into the exhaust square tube 9 through the outlet pipe 8, and finally blown out from the other end of the exhaust square tube 9. Since the opening of the exhaust square tube 9 is designed in a direction inclined toward the separation plate 3, it allows the high-pressure gas to be blown from the lower part of the separation plate 3 to the upper part, which can better blow away the impurities mixed in the nuts, separate them from the nut fruits, and fall into the dust box 5 through the separation plate 3 for unified collection. After the collection is full, open the box door 35 and remove the dust box 5 from the collection frame 4 for cleaning, which is convenient for operation. This device can reduce foreign matter in the nuts and improve the quality of the nuts after separation. And the automatic operation does not require manual secondary separation, which improves the efficiency of nut raw material screening and reduces investment costs.
