Abstract
Description
Technical Field
[0001] This utility model belongs to the field of carrot seed treatment technology, specifically a device for preventing clogging and delinting carrot seeds. Background Technology
[0002] Carrot seed harvesting and processing techniques are crucial to their yield. Most carrot seed production bases in China use manual harvesting. Compared to mechanical harvesting, manual harvesting allows for multiple batches of harvesting, ensuring that all harvested seeds meet the required maturity level. During manual harvesting, mature carrot inflorescences are first cut off and dried. Then, a carrot delinting machine is used to detach the seeds from the inflorescences. Large impurities such as long branches and flower stalks are separated and removed through a mesh screen, yielding crude carrot seeds. At this stage, the carrot seeds have fuzz, which can cause inflorescence fragments and other impurities to clump together, making them highly susceptible to moisture absorption and affecting subsequent packaging and storage. Therefore, carrot seed delinting equipment must be used to remove the fuzz from the carrot seeds.
[0003] Most carrot seed delinting equipment uses a power source to drive sticks to pound the seeds, and then separates the seeds from impurities such as hairs and inflorescences through tools such as sieves. However, existing carrot seed delinting devices often clog the sieves with hairs, inflorescences, and other impurities, requiring frequent shutdowns for cleaning, resulting in low efficiency. Therefore, it is necessary to design a carrot seed delinting device that automatically cleans impurities and prevents clogging. Utility Model Content
[0004] To address the above technical problems, this utility model provides an automatic carrot seed delinting device that cleans impurities and prevents clogging.
[0005] To solve the above technical problems, the technical solution of this utility model is as follows: a delinting device for preventing blockage of carrot seeds, including a delinting cylinder, a support leg, and a support base. The bottom of the delinting cylinder is fixedly connected to the support leg. A motor is fixedly connected to the support base. A rotating shaft is rotatably connected to the central shaft on both sides of the delinting cylinder. Several spirally spaced delinting teeth are fixedly connected to the rotating shaft. One end of the rotating shaft extends out of the delinting cylinder and is fixedly connected to the output end of the motor. A feeding hopper is fixedly connected to one side of the upper end of the delinting cylinder, and a negative pressure chamber inlet is fixedly connected to the other side of the upper end. A discharge valve is installed at the outlet of the feeding hopper. The negative pressure chamber is fixedly connected to the outside of the delinting cylinder. An air pump is connected to the negative pressure chamber. A chamber door is hinged to the outlet of the negative pressure chamber. A screen is fixedly connected to one side of the lower end of the delinting cylinder.
[0006] Furthermore, a blower fan is provided on the side of the delinting cylinder near the feed hopper. The blower fan shaft is sleeved on the rotating shaft and fixedly connected to the rotating shaft. A protective cover is provided on the outer periphery of the blower fan and fixedly connected to one side of the delinting cylinder.
[0007] Furthermore, a collection hopper is provided below the screen, the upper end of the collection hopper is fixedly connected to the lower side of the delinting cylinder, and a seed collection box is placed below the collection hopper.
[0008] Furthermore, a sieve plate is fixedly connected to the lower end of the negative pressure chamber, and a seed chamber is fixedly connected to the lower side wall of the negative pressure chamber below the sieve plate. A discharge port is opened at the lower end of the seed chamber, and a slide valve is installed on the discharge port.
[0009] Compared with the prior art, the present invention has the following advantages:
[0010] 1. This utility model connects a negative pressure chamber to the delinting cylinder. Under the action of gravity, the heavier carrot seeds are discharged through the screen below the delinting cylinder, while the lighter impurities such as lint are sucked into the negative pressure chamber above the delinting cylinder and collected. This prevents the lint and other impurities from accumulating inside the delinting cylinder and eventually clogging the screen, avoiding frequent shutdowns for cleaning and improving the efficiency of carrot seed delinting.
[0011] 2. This utility model opens an air inlet and installs a blower fan on the side of the delinting cylinder near the feed hopper. The blower fan is driven by a motor to rotate and blow air into the delinting cylinder. This can accelerate the movement of lint and other impurities in the delinting cylinder towards the negative pressure chamber, increase the adsorption efficiency of the negative pressure chamber for lint and other impurities, and ensure the cleaning effect of the negative pressure chamber on lint and other impurities in the delinting cylinder.
[0012] 3. This utility model, by installing a sieve plate at the bottom of the negative pressure chamber and connecting it to the seed chamber, can separate seeds that are accidentally sucked into the negative pressure chamber through the sieve plate and temporarily store them in the seed chamber. While cleaning impurities such as lint in the negative pressure chamber, the slide valve of the seed chamber discharge port is opened to discharge the carrot seeds in the seed chamber, thus avoiding the removal of these seeds along with impurities, which would adversely affect the yield of carrot seeds.

[0016] The present invention will be further described below with reference to the accompanying drawings.
[0017] like Figure 1 , Figure 2 The device shown is a delinting device for preventing clogging of carrot seeds, comprising a delinting cylinder 1, support legs 2, and support base 3. The bottom of the delinting cylinder 1 is fixedly connected to the support legs 2. A motor 4 is fixedly connected to the support base 3. A rotating shaft 5 is rotatably connected to the central shafts on both sides of the delinting cylinder 1 via bearings. Several spirally spaced delinting teeth 6 are fixedly connected to the rotating shaft 5. The delinting teeth 6 are evenly distributed on the rotating shaft 5. To increase the contact area between the carrot seeds and the delinting teeth 6, the delinting teeth 6 are inclined. One end of the rotating shaft 5 extends out of the delinting cylinder 1 and is fixedly connected to the output end of the motor 4 via a coupling. The upper side of the delinting cylinder 1 is fixedly connected to... The feed hopper 7 is connected to the feed inlet of the negative pressure chamber 8, which is fixedly connected to the other side of the upper end. The feed hopper 7 is equipped with a discharge valve, which is an electric star-shaped discharge valve. The negative pressure chamber 8 is fixedly connected to the outside of the delinting cylinder 1. The negative pressure chamber 8 is connected to a vacuum pump 9. The vacuum pump 9 works continuously to create a negative pressure inside the negative pressure chamber 8. A door 10 is hinged to the discharge port of the negative pressure chamber 8. When the door 10 is closed and locked, it seals against the side wall of the negative pressure chamber 8. A screen 11 is fixedly connected to one side of the lower end of the delinting cylinder 1. The mesh size of the screen 11 is larger than the average length of the carrot seeds so that the carrot seeds can pass through the screen 11 smoothly.
[0018] To facilitate the entry of impurities such as lint into the negative pressure chamber 8, a blower fan 12 is provided on the side of the delinting cylinder 1 near the feed hopper 7. An air inlet is provided on the side wall of the delinting cylinder 1 near the feed hopper 7. The shaft of the blower fan 12 is sleeved on the rotating shaft 5 and fixedly connected to the rotating shaft 5. While the motor 4 drives the rotating shaft 5 to rotate, the blower fan 12 rotates and blows air into the delinting cylinder 1, blowing the impurities such as lint toward the feed port of the negative pressure chamber 8 at the other end of the delinting cylinder 1. A protective cover 13 is provided on the outer periphery of the blower fan 12 and fixedly connected to one side of the delinting cylinder 1.
[0019] In order to temporarily collect the carrot seeds that fall from the sieve 11 and prevent them from scattering, a collection hopper 14 is provided below the sieve 11. The collection hopper 14 is a square cone-shaped funnel. The upper end of the collection hopper 14 is fixedly connected to the lower side of the delinting cylinder 1. A seed collection box 15 is placed below the collection hopper 14 to collect the carrot seeds that fall from the collection hopper 14.
[0020] In order to separate and collect the carrot seeds sucked into the negative pressure chamber 8 and prevent them from being cleaned away along with impurities, a sieve plate 16 is fixedly connected to the lower end of the negative pressure chamber 8. The sieve hole diameter of the sieve plate 16 is the same as that of the mesh 11. A seed chamber 17 is fixedly connected to the lower side wall of the negative pressure chamber 8 below the sieve plate 16. A discharge port is opened at the lower end of the seed chamber 17. A seed collection box 15 is also set below the discharge port. A gate valve 18 is installed on the discharge port.
[0021] The specific working process of this utility model is as follows:
[0022] The crude carrot seeds are added to the feed hopper 7. The motor 4 and the vacuum pump 9 are started. The rotating shaft 5 rotates under the drive of the motor 4, which in turn drives the blower fan 12 and the delinting teeth 6 connected to the rotating shaft 5 to rotate. The vacuum pump 9 continuously removes air from the negative pressure chamber 8, creating a temporary negative pressure inside the chamber. The discharge valve of the feed hopper 7 is then opened, and the crude carrot seeds enter the delinting cylinder 1. Under the impact of the delinting teeth 6, the seeds gradually lose their fuzz. The delinted carrot seeds are heavier than the fuzz and other impurities, so they fall through the screen 11 into the collection hopper 14 and are eventually collected in the seed collection box 15. The fuzz and other impurities are lighter and move to the left side of the delinting cylinder 1 under the airflow from the blower fan 12. When passing through the inlet of the negative pressure chamber 8 on the left side of the delinting cylinder 1, the seeds are drawn into the negative pressure chamber 8 by the negative pressure airflow to prevent impurities such as lint from accumulating in the delinting cylinder 1 and eventually clogging the screen 11. Delinted carrot seeds that accidentally enter the negative pressure chamber 8 fall through the screen plate 16 into the seed chamber 1 for temporary storage. After processing a batch of crude carrot seeds, the motor 4 and the vacuum pump 9 are turned off in time, the chamber door 10 is opened, and the lint and other impurities in the negative pressure chamber 8 are cleaned. At the same time, the baffle valve 18 is opened to discharge the carrot seeds in the seed chamber 11 into the seed collection box 15. After cleaning, the baffle valve 18 and the chamber door 10 are closed, and the motor 4 and the vacuum pump 9 are restarted. The carrot seeds are delinted again according to the above steps.
