Abstract
Description
Technical Field
[0001] This utility model relates to the field of harvester technology, and in particular to a double-spiral auger feeding device for a seed melon harvester and the seed melon harvester itself. Background Technology
[0002] Seed watermelons are a branch of watermelons. Unlike common edible watermelons, seed watermelon cultivation primarily focuses on harvesting the seeds, which have economic value, including edible properties. Besides the traditionally utilized seeds, the rind contains abundant natural pectin and dietary fiber, while the pulp juice contains sugars and other organic nutrients. During harvesting and transportation, if the conveyor system is inadequate, seed watermelons may be damaged during transport, preventing them from entering the fruit-breaking mechanism and severely impacting the quality of the seeds produced.
[0003] In existing technologies, two common seed-carrying mechanisms are used in seed-harvesting machines: one uses baffles evenly spaced on a conveyor belt, and the other is a spiral auger conveyor. Conveying with a conveyor belt with baffles requires a specific conveying angle; a large angle can cause seeds to roll off and become damaged. Spiral auger conveyors, on the other hand, allow for adjustable conveying angles, reducing the risk of seed roll-off and making them the most common seed-harvesting method in this field. However, in recent years, the increasing number of seed-harvesting machines has led to a shortage of arable land, resulting in higher demands from large-scale growers and professional operators for harvester efficiency. Traditional single-drum feeding devices can no longer meet these needs. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a double-spiral auger feeding device for a seed melon harvester and a seed melon harvester, so as to solve the problems of low efficiency and uneven distribution of seeds and melons in a single auger feeding mechanism.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A double spiral auger feeding device for a seed melon harvester includes two parallel feeding cylinders. Both feeding cylinders are inclined and their outer walls are fixedly connected. The top of each feeding cylinder is provided with an upper fixed plate and the bottom is provided with a lower fixed plate. The bottom side of each feeding cylinder is provided with a feed inlet and the top side of each feeding cylinder is provided with a discharge outlet. Both the feed inlet and the discharge outlet are connected to the two feeding cylinders. The two feeding cylinders located between the feed inlet and the discharge outlet are not connected to each other. Each of the two feeding cylinders is provided with a spiral auger mechanism extending along the length direction of the feeding cylinder. The two ends of the spiral auger mechanism are rotatably connected to the upper fixed plate and the lower fixed plate respectively through bearing seats. One end of the spiral auger mechanism is externally connected to a drive mechanism.
[0006] The beneficial effects of this utility model are: the seeds and melons enter the subsequent mechanism under the pushing action of the double spiral auger, which greatly improves the working efficiency compared with the traditional single spiral auger feeding mechanism; when the seeds and melons are lifted to the discharge port, due to the action of the double spiral augers, the seeds and melons are relatively evenly distributed after entering the subsequent mechanism, reducing the failure of the subsequent mechanism caused by uneven distribution of seeds and melons.
[0007] Based on the above technical solution, the present invention can be further improved as follows.
[0008] Furthermore, the spiral auger mechanism includes an auger shaft, the two ends of which are rotatably connected to the upper fixed plate and the lower fixed plate respectively through the bearing seats. The end of the auger shaft is connected to the drive mechanism. Spiral auger blades are fixedly provided on the auger shaft. A steel bar is fixedly provided on the outer edge of the auger blades located at the lower part of the upper feed cylinder. The length direction of the steel bar extends along the edge of the auger blades.
[0009] The beneficial effect of adopting the above-mentioned further solution is that reinforcing bars are set on the edge of the auger blades at the feed inlet, which effectively reduces the loss of seeds caused by seed breakage during the lifting process.
[0010] Furthermore, a scraper is fixedly provided on the upper outer wall of the auger shaft, and the scraper is located at the discharge port.
[0011] The beneficial effect of adopting the above-mentioned further solution is that by setting a scraper on the upper part of the auger shaft to assist in material discharge, the seeds and melons are prevented from accumulating at the discharge port and causing damage to the seeds and melons.
[0012] Furthermore, a uniformly distributed baffle is provided between the bottoms of the two feeding cylinders, and the uniformly distributed baffle is located between the inner walls of the two feeding cylinders away from the feed inlet.
[0013] The beneficial effects of adopting the above-mentioned further solution are: when the seeds enter the feed inlet, they are evenly distributed to the two sides of the feed cylinder by the uniform distribution baffle, which further improves the uniformity of the distribution of seeds after entering the subsequent mechanism and reduces the failure of the subsequent mechanism due to uneven distribution of seeds.
[0014] Furthermore, the outer walls of the two feeding cylinders are fixedly connected by a housing fixing plate.
[0015] The advantages of adopting the above-mentioned further solution are: the two feeding cylinders are fixedly connected by the shell fixing plate, and the structure is simple.
[0016] Furthermore, the upper part of the feeding cylinder is provided with an observation window for observing the inside of the feeding cylinder.
[0017] The beneficial effects of adopting the above-mentioned further solution are: the observation window makes it convenient to observe the conveying situation inside the feeding cylinder, and it also makes it convenient to clean the inside of the feeding cylinder when a fault occurs.
[0018] Furthermore, the lower fixing plate is provided with multiple flow holes.
[0019] The beneficial effect of adopting the above-mentioned further solution is that the setting of the flow hole facilitates the leakage of soil and melon juice.
[0020] Furthermore, a first adjusting screw is provided at the upper part of the two feeding cylinders. One end of the first adjusting screw is hinged to the outer wall of the feeding cylinder, and the other end is used to hinge to the external frame. A second adjusting screw is provided below the discharge port. One end of the second adjusting screw is hinged to the outer wall of the feeding cylinder, and the other end is used to hinge to the subsequent mechanism.
[0021] The beneficial effects of adopting the above-mentioned further solution are: the tilt angle of the entire feeding mechanism can be adjusted by the first adjusting screw, and the setting of the second adjusting screw can facilitate the hinge connection with the subsequent mechanism and ensure the connection strength with the subsequent mechanism.
[0022] Furthermore, a connecting frame is provided below the discharge port, and the connecting frame is fixedly connected to the outer walls of both feeding cylinders. The first adjusting screw and the second adjusting screw are both hinged to the connecting frame.
[0023] The beneficial effect of adopting the above-mentioned further solution is that the setting of the connecting bracket facilitates the setting of the first adjusting screw and the second adjusting screw.
[0024] This utility model solves the above-mentioned technical problems and also provides a seed melon harvester, including the above-mentioned double spiral auger feeding device for seed melon harvesters.
[0025] The beneficial effects of adopting the above scheme are: the seeds and melons enter the subsequent mechanism under the pushing action of the double spiral auger, which greatly improves the working efficiency compared with the traditional single auger feeding mechanism. Due to the action of the double auger, the seeds and melons are relatively evenly distributed after entering the subsequent mechanism, reducing the failure caused by uneven distribution of seeds and melons in the subsequent mechanism.

[0033] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0034] Example 1
[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, an embodiment of this utility model includes two parallel feeding cylinders 1, both of which are inclined. The outer walls of the two feeding cylinders 1 are fixedly connected by a housing fixing plate 11. Specifically, the housing fixing plate 11 is provided with through holes that match the two feeding cylinders 1. The two feeding cylinders 1 are respectively fixedly installed in the two through holes. The feeding cylinders 1 can be fixedly connected to the inner wall of the through holes by welding, and the outer walls of the two feeding cylinders 1 abut against each other.
[0036] like Figure 2 , Figure 3 As shown, in order to ensure the stability of the fixed connection between the two feeding cylinders 1 and to enhance the strength of the connection between the two feeding cylinders 1, the two feeding cylinders 1 are also fixedly connected by a plurality of reinforcing ribs 16, which are spaced apart along the length direction of the feeding cylinders 1.
[0037] The top of the feeding cylinder 1 is provided with an upper fixing plate 2, and the bottom is provided with a lower fixing plate 3. The upper fixing plate 2 is fixedly connected to the top of both feeding cylinders 1 by bolts or welding. The upper fixing plate 2 also covers the top of both feeding cylinders 1. The lower fixing plate 3 is fixedly connected to the bottom of both feeding cylinders 1 by bolts or welding. The lower fixing plate 3 covers the bottom of both feeding cylinders 1. Through this setting, the top and bottom of the two feeding cylinders 1 can be fixed, ensuring the stability of the connection between the two feeding cylinders 1.
[0038] like Figure 3 As shown, the bottom side of the feeding cylinder 1 is provided with a feeding port 4, and the top side of the feeding cylinder 1 is provided with a discharging port 5. Both the feeding port 4 and the discharging port 5 are connected to the two feeding cylinders 1. The two feeding cylinders 1 located between the feeding port 4 and the discharging port 5 are not connected to each other. Specifically, the feeding port 4 is located between the bottoms of the two feeding cylinders 1. The two feeding cylinders 1 have a lower opening on the side wall corresponding to the feeding port 4. The feeding port 4 is formed by a mouth-shaped structure formed by a surrounding plate at the lower opening. The bottoms of the two feeding cylinders 1 are connected to each other to facilitate feeding. At the same time, a uniformly distributed baffle 7 is provided between the bottoms of the two feeding cylinders 1. The uniformly distributed baffle 7 is located between the inner walls of the two feeding cylinders 1 away from the feeding port 4.
[0039] Preferably, the uniform distribution baffle 7 includes two uniform distribution plates disposed between the bottoms of the two feeding cylinders 1. The two uniform distribution plates are arranged at an angle and are arc-shaped. When the seeds enter the bottom of the two feeding cylinders 1 from the feed inlet 4, the seeds are guided by the two uniform distribution plates, so that the seeds are smoothly introduced into the two feeding cylinders 1 respectively.
[0040] The top sidewalls of the two feeding cylinders 1 are provided with upper openings, and the two feeding cylinders 1 at the upper openings are interconnected. The discharge port 5 is formed by a surrounding plate around the opening. The discharge port 5 is provided with a connecting plate 9 around its perimeter. The connecting plate 9 is provided with multiple fixing holes 10. By setting the connecting plate 9 and the fixing holes 10, it is convenient to connect to the rear melon cutting mechanism with bolts.
[0041] Both feeding cylinders 1 are provided with a spiral auger mechanism 6 extending along the length of the feeding cylinder 1. The two ends of the spiral auger mechanism 6 are rotatably connected to the upper fixed plate 2 and the lower fixed plate 3 respectively through bearing seats. One end of the spiral auger mechanism 6 is externally connected to a drive mechanism.
[0042] like Figure 4 , Figure 5As shown in the embodiment of this utility model, the spiral auger mechanism 6 includes an auger shaft 601. The two ends of the auger shaft 601 are rotatably connected to the upper fixed plate 2 and the lower fixed plate 3 respectively through the bearing seats. The end of the auger shaft 601 is connected to the drive mechanism. A spiral auger blade 602 is fixedly provided on the auger shaft 601. A steel bar 603 is fixedly provided on the outer edge of the auger blade 602 located at the lower part of the upper feed cylinder 1. The length direction of the steel bar 603 extends along the edge of the auger blade 602. The steel bar 603 is provided on the edge of the auger blade 602 at the feed inlet 4, which effectively reduces the loss of seeds caused by the crushing of seeds during the lifting process.
[0043] In a preferred embodiment of this utility model, a scraper 604 is fixedly provided on the upper outer wall of the auger shaft 601. The scraper 604 is located at the discharge port 5. By providing a scraper 604 on the upper part of the auger shaft 601, the material can be discharged in an auxiliary manner, thus preventing the seeds and melons from accumulating at the discharge port 5 and causing damage to the seeds and melons.
[0044] The upper part of the feeding cylinder 1 is provided with an observation window 12 for observing the inside of the feeding cylinder 1. In one embodiment of the present invention, the observation window 12 includes an observation port provided on the feeding cylinder 1 and an observation door for opening and closing the observation port. The observation window 12 facilitates the observation of the conveying situation inside the feeding cylinder 1, and also facilitates the cleaning of the inside of the feeding cylinder 1 in case of a malfunction.
[0045] The lower fixing plate 3 is provided with multiple flow holes 13 to allow soil and melon juice to leak down from the flow holes 13, thus preventing soil and melon juice from accumulating on the lower fixing plate 3.
[0046] In an embodiment of this utility model, a first adjusting screw 8 is provided at the upper part of the two feeding cylinders 1. One end of the first adjusting screw 8 is hinged to the outer wall of the feeding cylinder 1, and the other end is used to hinge to the external frame. A second adjusting screw 14 is provided below the discharge port 5. One end of the second adjusting screw 14 is hinged to the outer wall of the feeding cylinder 1, and the other end is used to hinge to a subsequent mechanism (such as a melon crushing chamber). Further, a connecting frame 15 is provided below the discharge port 5. The connecting frame 15 is fixedly connected to the outer walls of both feeding cylinders 1. Both the first adjusting screw 8 and the second adjusting screw 14 are hinged to the connecting frame 15 (the specific structure of the first adjusting screw 8 and the second adjusting screw 14 is prior art and will not be described in detail here). The setting of the connecting frame 15 facilitates the setting of the first adjusting screw 8 and the second adjusting screw 14.
[0047] In this embodiment, the connecting frame 15 facilitates the setting of the first adjusting screw 8 and the second adjusting screw 14. The seed melons enter the subsequent mechanism under the pushing action of the double-spiral auger, significantly improving work efficiency compared to the traditional single-auger feeding mechanism. When the material is lifted to the discharge port 5, due to the action of the double augers, the material is relatively evenly distributed after entering the subsequent mechanism, reducing malfunctions caused by uneven material distribution. The inner cavities of the two feeding cylinders 1 are independent of each other, preventing melon vines and weeds from entangled and causing blockages.
