Technical Field

[0001] The invention relates to the technical field of oil-tea fruit processing, in particular to a quantitative weighing device for oil-tea fruit and a working method thereof. Background Art

[0002] Tea oil fruit, also known as oil tea fruit, is the fruit of the oil tea tree. The camellia oil squeezed from the tea oil fruit can not only be used as a healthy cooking oil in daily life, used for cooking and making soup, etc., making the dishes light and non-greasy, but also rich in nutrition. At the same time, it can also be used to apply on the skin, which has the effect of reducing swelling and itching. After picking the tea oil fruit, it needs to be peeled and dried in turn, and then the obtained camellia seeds are squeezed to obtain the finished camellia oil.

[0003] Before peeling the picked tea-oil fruits, they need to be quantitatively weighed. Since the picking period of tea-oil fruits is around the frost season, most of the tea-oil fruits are ripe, and cracks will appear on the surface of ripe tea-oil fruits, which are easy to absorb moisture and affect the accuracy of the weighing data of the tea-oil fruits. At the same time, in the existing process of transporting the tea-oil fruits to the weighing structure, they need to be quantitatively distributed through a feed pipe. Due to the influence of the cracks on the surface of the tea-oil fruits, the feed pipe is easily blocked, which will affect the efficiency of the normal quantitative weighing of the tea-oil fruits. Summary of the invention

[0004] The technical problems solved by this solution are:

[0005] (1) How to solve the problem that the cracks on the surface of tea oil fruit easily cause blockage in the feeding pipe, which will affect the normal quantitative weighing efficiency of tea oil fruit;

[0007] The object of the present invention can be achieved through the following technical scheme: a quantitative weighing device for tea oil fruit, comprising a base and a weighing platform fixedly embedded on the top of the base, a storage box for loading tea oil fruit is arranged on the top of the weighing platform, and a mounting cover is fixedly arranged on one side of the weighing platform, a feeding pipe is fixedly inserted on the top of the mounting cover, an air-drying mechanism for drying tea oil fruit is arranged below the feeding pipe, and a material guiding mechanism for unblocking the feeding pipe is arranged on the front of the air-drying mechanism;

[0009] A further technical improvement of the present invention is that a cylinder is fixedly inserted on the base, the cylinder is longitudinally arranged, and a lever and a pressing plate are fixedly installed on the protruding end of the cylinder. A through hole is opened on the top inner wall of the material guide trough, and a guide block is movably inserted in the through hole, and the position and size of the guide block correspond to the output end of the discharge pipe.

[0010] A further technical improvement of the present invention is that: a force storage groove is provided at the bottom of the guide block, a first thrust spring is elastically arranged in the force storage groove, and the top end of the protruding end of the cylinder extends into the force storage groove; by timely controlling the protruding end of the cylinder to extend to the longest, the guide block extends into the discharge pipe, and the partition plate is slowly pulled out of the discharge pipe. During this process, due to the obstruction of the partition plate, the tea oil fruit remaining between the partition plate and the guide block provides pressing pressure to the guide block, so that the first thrust spring is squeezed and shortened in the force storage groove. When the partition plate is completely pulled out of the discharge pipe, the protruding end of the cylinder extends to cooperate with the thrust released by the first thrust spring, and provides thrust to the tea oil fruit stuck in the discharge pipe through the guide block, thereby achieving the effect of unblocking the discharge pipe.

[0011] A further technical improvement of the present invention is that the closed unit includes a partition plate movably inserted in the middle of the discharge pipe, one end of the partition plate is fixedly connected to a push-pull rod, the end of the push-pull rod away from the partition plate movably passes through the mounting cover, and the middle part of the push-pull rod is fixedly connected to a fixing pin; a guide frame for guiding the push-pull rod is fixedly installed on the inner wall of the mounting cover, and a tension spring is fixedly connected between the guide frame and the partition plate.

[0012] A further technical improvement of the present invention is that a flip rod is rotatably provided on the inner wall of the mounting cover, one end of the flip rod is slidably connected to a fixing pin, and the other end of the flip rod is fixedly connected to an L-shaped rod, and the middle part of the L-shaped rod is slidably connected to the lever.

[0013] A further technical improvement of the present invention is that the air-drying mechanism includes an adjusting tube fixedly arranged on the top of the base, the adjusting tube is longitudinally arranged, and a transmission rod is movably inserted at the top of the adjusting tube, a limiting plate is fixedly installed on the top of the transmission rod, a second thrust spring is elastically arranged between the limiting plate and the adjusting tube, and the position of the limiting plate corresponds to the position of the pressing plate, and a piston is fixedly installed on the bottom end of the transmission rod.

[0014] A further technical improvement of the present invention is that: a first air pipe is connected to the side of the top of the regulating tube, an output end of the first air pipe is in contact with the side of the storage box, a second air pipe is connected to the bottom of the regulating tube, an output end of the second air pipe is connected to the middle of the discharge pipe, and the output end of the second air pipe is located above the partition plate; the L-shaped rod is pushed to rotate by the lever, and the flip rod drives the fixed pin and the push-pull rod to move horizontally, so that the partition plate blocks the inside of the discharge pipe, and the hot air blower is turned on, so that the blown hot air flow is injected into the discharge pipe through the regulating tube and the second air pipe, and then blown out from the opening of the discharge hopper. In the process of the hot air flow passing through the discharge hopper, it is convenient to dry the moisture at the cracks on the surface of the tea fruit, so as to avoid affecting the accuracy of the tea oil fruit weighing data.

[0015] A further technical improvement of the present invention is that a hot air blower is arranged on one side of the regulating pipe, the output end of the hot air blower is connected to the regulating pipe, and the output end of the hot air blower is located between the input end of the first air pipe and the input end of the second air pipe, and the output end diameter of the second air pipe is smaller than the diameter of the tea oil fruit.

[0016] A working method of a quantitative weighing device for oil-tea camellia fruit, the working method specifically comprising the following steps:

[0017] Step 1: Pour the picked tea fruit into the lower hopper through the external feeding equipment. At this time, the extended end of the cylinder is at half the length, the pressing plate is not in contact with the limit plate, the L-shaped rod is pushed to rotate by the lever, and the flip rod drives the fixed pin and the push-pull rod to move horizontally, so that the partition plate blocks the inside of the lower feeding pipe, and the hot air blower is turned on, so that the hot air flow blown out is injected into the lower feeding pipe through the regulating pipe and the second air pipe, and then blown out from the opening of the lower hopper. In the process of the hot air flow passing through the lower hopper, it is convenient to dry the moisture on the cracks on the surface of the tea fruit, so as to avoid affecting the accuracy of the tea fruit weighing data;

[0018] Step 2: After the tea-oil fruit in the lower hopper is dried, the extended end of the cylinder is controlled to extend from half the length to the set length, and the guide block rises to correspond to the bottom of the inner wall of the guide trough. At this time, the partition plate is partially pulled out of the lower tube through the tension of the tension spring, and the tea-oil fruit in the lower tube falls from the gap between the partition plate and the inner wall of the lower tube, and after colliding with the guide block, it enters the storage box along the guide trough;

[0019] Step 3: If a blockage occurs in the discharge pipe, the extended end of the cylinder is promptly controlled to extend to the longest position, so that the guide block extends into the discharge pipe, and the partition plate is slowly withdrawn from the discharge pipe. During this process, due to the obstruction of the partition plate, the tea-oil fruit remaining between the partition plate and the guide block provides a pressing force to the guide block, so that the first thrust spring is squeezed and shortened in the force storage groove. When the partition plate is completely withdrawn from the discharge pipe, the extended end of the cylinder is extended to cooperate with the thrust released by the first thrust spring, and the tea-oil fruit stuck in the discharge pipe is provided with a thrust through the guide block, thereby achieving the effect of unblocking the discharge pipe;

[0020] Step 4: After the set amount of tea oil fruit is loaded in the storage box, control the extended end of the cylinder to shrink to the shortest, and the lever will slide from the top of the L-shaped rod through the middle and then to the bottom. During this process, the partition plate will not move after blocking the discharge pipe. The pressing plate provides pressure to the limit plate to make the piston move downward to the lowest point. At this time, the piston is located between the output end of the hot blower and the input end of the second air pipe, so that the hot air flow blown out from the hot blower will be blown out from the output end of the first air pipe, pushing the storage box to move, and cooperating with the baffle and the elastic thrust of the third thrust spring to make the storage box swing back and forth, thereby leveling the tea oil fruit in the storage box. After turning off the hot blower, the storage box stops steadily, which is convenient for accurate weighing of the tea oil fruit.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] When the present invention is in use, the extended end of the cylinder is timely controlled to extend to the longest length, so that the guide block extends into the discharge pipe and the partition plate is slowly pulled out of the discharge pipe. During this process, due to the obstruction of the partition plate, the tea oil fruit remaining between the partition plate and the guide block provides pressing pressure to the guide block, so that the first thrust spring is squeezed and shortened in the force storage groove. When the partition plate is completely pulled out of the discharge pipe, the extended end of the cylinder is extended to cooperate with the thrust released by the first thrust spring, and the tea oil fruit stuck in the discharge pipe is provided with thrust through the guide block, thereby achieving the effect of unblocking the discharge pipe.

[0023] When the present invention is in use, the L-shaped rod is pushed to rotate by the lever, and the flip rod drives the fixing pin and the push-pull rod to move horizontally, so that the partition plate blocks the inside of the discharge pipe, and the hot air blower is turned on to allow the blown hot air flow to be injected into the discharge pipe through the regulating pipe and the second air pipe, and then blown out from the opening of the discharge hopper. In the process of the hot air flow passing through the discharge hopper, the moisture on the cracks on the surface of the oil-tea fruit is dried, thereby avoiding affecting the accuracy of the weighing data of the oil-tea fruit.

[0047] A working method of a quantitative weighing device for oil-tea camellia fruit, the working method specifically comprising the following steps:

[0048] Step 1: Pour the picked tea-oil fruits into the lower hopper 1 through the external feeding equipment. At this time, the extended end of the cylinder 303 is at half the length, and the pressing plate 304 is not in contact with the limit plate 906. The L-shaped rod 305 is pushed to rotate by the lever 310, and the flip rod 306 drives the fixing pin 308 and the push-pull rod 307 to move horizontally, so that the partition plate 301 blocks the inside of the lower feeding pipe 8, and the hot air blower 902 is turned on, so that the blown hot air flow is injected into the lower feeding pipe 8 through the regulating pipe 903 and the second air pipe 907, and then blown out from the opening of the lower hopper 1. In the process of the hot air flow passing through the lower hopper 1, it is convenient to dry the moisture at the cracks on the surface of the tea-oil fruits, so as to avoid affecting the accuracy of the tea-oil fruit weighing data;

[0049] Step 2: After the tea-oil fruits in the lower hopper 1 are dried, the extended end of the cylinder 303 is controlled to extend from half the length to the set length, and the guide block 311 rises to correspond to the bottom of the inner wall of the guide groove 302. At this time, the partition plate 301 is partially drawn out of the lower tube 8 by the tension of the tension spring, and the tea-oil fruits in the lower tube 8 fall from the gap between the partition plate 301 and the inner wall of the lower tube 8, and after colliding with the guide block 311, they enter the storage box 4 along the guide groove 302;

[0050] Step 3: If a blockage occurs in the feed pipe 8, the extended end of the cylinder 303 is promptly controlled to extend to the longest position, so that the guide block 311 extends into the feed pipe 8, and the partition plate 301 is slowly withdrawn from the feed pipe 8. During this process, due to the obstruction of the partition plate 301, the tea-oil fruit remaining between the partition plate 301 and the guide block 311 provides a pressing force to the guide block 311, so that the first thrust spring is squeezed and shortened in the force storage groove 313. When the partition plate 301 is completely withdrawn from the feed pipe 8, the extended end of the cylinder 303 is extended to cooperate with the thrust released by the first thrust spring, and the guide block 311 provides a thrust to the tea-oil fruit stuck in the feed pipe 8, thereby achieving the effect of unblocking the feed pipe 8.

[0051] Step 4: After a set amount of tea oil fruit is loaded in the storage box 4, the extended end of the control cylinder 303 is retracted to the shortest, and the lever 310 will slide from the top of the L-shaped rod 305 through the middle thereof and then to its bottom. During this process, the partition plate 301 will not move after blocking the discharge pipe 8. The pressure is provided to the limit plate 906 through the pressing plate 304, so that the piston 904 moves downward to the lowest point. At this time, the piston 904 is located between the output end of the hot air blower 902 and the input end of the second air pipe 907, so that the hot air flow blown out from the hot air blower 902 will be blown out from the output end of the first air pipe 901, pushing the storage box 4 to move, and cooperating with the baffle 10 and the elastic thrust of the third thrust spring, the storage box 4 swings back and forth, thereby leveling the tea oil fruit in the storage box 4. After turning off the hot air blower 902, the storage box 4 stops steadily, which is convenient for accurately weighing the tea oil fruit.

The working method of the quantitative weighing device for oil-tea camellia fruit according to any one of claims 1 to 8, characterized in that: The working method specifically comprises the following steps: Step 1: Pour the picked tea-oil fruits into the lower hopper (1) through an external loading device. At this time, the extended end of the cylinder (303) is at half its length, and the pressing plate (304) is not in contact with the limit plate (906). The L-shaped rod (305) is pushed to rotate by the lever (310), and the flip rod (306) drives the fixing pin (308) and the push-pull rod (307) to move horizontally, so that the partition plate (301) blocks the inside of the lower feeding pipe (8). The hot air blower (902) is turned on, so that the hot air flow blown out is injected into the lower feeding pipe (8) through the regulating pipe (903) and the second air supply pipe (907), and then blown out from the opening of the lower feeding hopper (1); Step 2: After the tea-oil fruits in the lower hopper (1) are dried, the extended end of the cylinder (303) is controlled to extend from half the length to the set length, and the guide block (311) rises to correspond to the bottom of the inner wall of the guide groove (302). At this time, the partition plate (301) is partially drawn out of the lower tube (8) by the tension of the tension spring, and the tea-oil fruits in the lower tube (8) fall from the gap between the partition plate (301) and the inner wall of the lower tube (8), and after colliding with the guide block (311), enter the storage box (4) along the guide groove (302); Step 3: If a blockage occurs in the feed tube (8), the extended end of the cylinder (303) is promptly controlled to extend to the longest position, so that the guide block (311) extends into the feed tube (8), and the partition plate (301) is slowly withdrawn from the feed tube (8). During this process, due to the obstruction of the partition plate (301), the tea oil fruit remaining between the partition plate (301) and the guide block (311) provides a pressing force to the guide block (311), so that the first thrust spring is squeezed and shortened in the force storage groove (313). When the partition plate (301) is completely withdrawn from the feed tube (8), the extended end of the cylinder (303) is extended to cooperate with the thrust released by the first thrust spring. Step 4: After a set amount of tea oil fruit is loaded into the storage box (4), the extended end of the control cylinder (303) is contracted to the shortest, and the lever (310) slides from the top of the L-shaped rod (305) through the middle thereof and then to the bottom thereof. During this process, the partition plate (301) will not move after blocking the feed pipe (8). The pressure is provided to the limit plate (906) through the pressing plate (304), so that the piston (904) moves downward to the lowest point. At this time, the piston (904) is located between the output end of the hot air blower (902) and the input end of the second air pipe (907), so that the hot air flow blown out from the hot air blower (902) will be blown out from the output end of the first air pipe (901), pushing the storage box (4) to move, and cooperating with the baffle plate (10) and the elastic thrust of the third thrust spring, so that the storage box (4) swings back and forth.
