Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, and in particular relates to a scallion digging device and method. Background Technology

[0002] With the development of agricultural technology, the planting and harvesting techniques for scallions, as an important economic crop, are constantly improving. However, existing scallion digging equipment still has some problems, such as uneven digging depth, high scallion damage rate, and low digging efficiency. These problems seriously affect the yield and quality of scallions, increasing the labor intensity and production costs for farmers.

[0003] Traditional double-auger scallion digging devices typically employ a double-auger structure, using a rotating auger to excavate the scallions from the soil. However, this method tends to mix the scallion roots with the soil during digging, making the scallions difficult to clean and affecting their quality. Furthermore, the digging depth and efficiency of traditional double-auger digging devices cannot meet the needs of modern agricultural production. Summary of the Invention

[0004] In view of the defects or deficiencies in the existing technology, the present invention provides a scallion digging device and method, which can separate the scallion roots from the soil during the digging process, ensuring the quality of scallion digging, and allowing the overall digging mechanism to freely and flexibly control the soil entry angle and depth, thereby improving the efficiency of scallion digging.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] In a first aspect, embodiments of the present invention provide a scallion digging device and method, including a double-auger digging mechanism and a hydraulic power system. The double-auger digging mechanism includes a digging shovel and two symmetrically arranged augers directly below it. The double-auger digging mechanism is connected to the hydraulic power system through the auger rods, and is powered by the hydraulic power system.

[0007] Furthermore, the double auger digging mechanism also includes a shovel bar, an auger rod, and a lower fixed pad. There are two shovel bars and two auger rods. The two shovel bars are parallel to each other, and the two auger rods are parallel to each other. One end of the two shovel bars is fixedly connected to the digging shovel, and the other end is fixedly connected to the lower fixed pad.

[0008] Furthermore, the ends of the two auger rods near the excavator shovel are fixedly connected to the double auger.

[0009] Furthermore, the shovel rod and the auger rod are fixedly connected by a connecting mechanism.

[0010] Furthermore, the hydraulic power system includes a hydraulic motor, the output shaft of which is connected to the auger rod, and the end of the hydraulic motor away from the auger rod is fixed to the lower fixed plate.

[0011] Furthermore, it also includes a controllable adjustment mechanism, which includes a bottom bracket and a telescopic sleeve. One end of the telescopic sleeve is hinged to the bottom bracket, and the other end is fixedly connected to the vehicle frame.

[0012] Furthermore, in the scallion digging device as described in claim 6, the telescopic sleeve includes an inner cylinder and an outer cylinder, the outer cylinder is sleeved on the outside of the inner cylinder, the inner cylinder and the outer cylinder are slidably connected, a groove is provided on the side wall of the outer cylinder, a bolt is provided in the groove, and the bolt passes through the groove and is threadedly connected to the inner cylinder.

[0013] Furthermore, in the scallion digging device as described in claim 6, the bottom bracket is welded and fixed to the lower fixing plate.

[0014] Furthermore, in the scallion digging device as described in claim 6, the hydraulic power system includes a hydraulic cylinder, a connecting inclined plate is provided on the telescopic sleeve, one end of the hydraulic cylinder is hinged to the connecting inclined plate, and the other end is hinged to the shovel rod.

[0015] Secondly, embodiments of the present invention provide a method for digging up scallions, utilizing a scallion digging device as described above, comprising the following steps:

[0016] When in use, first start the hydraulic motor. The hydraulic motor drives the double augers to rotate in opposite directions through the auger rod, interlacing to break and loosen the soil. At the same time, the digging shovel is used to cut the soil and dig up the scallions. The front end of the digging shovel is used to cut the soil, and the rear end is designed to fold at a set angle to facilitate the digging of scallions. During the digging process, the soil entry angle and soil entry depth of the digging mechanism are adjusted by the hydraulic cylinder and telescopic sleeve.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. This invention uses a double auger digging device installed at the bottom of the chassis body. With the cooperation of the double auger and the digging shovel, the double auger first drills into the soil to break and loosen it, and then the digging shovel digs the scallions. This can separate the roots of the scallions from the soil during the digging process, ensuring the quality of the scallion digging.

[0019] 2.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Example 1

[0026] A typical embodiment of the present invention, such as Figure 1 As shown, a scallion digging device includes a double-auger digging mechanism, a controllable adjustment mechanism, and a hydraulic power system. The double-auger digging mechanism includes a digging shovel 1 and a double auger 3 aligned directly below it, which are fixed together by a connecting mechanism 11. The controllable adjustment mechanism can change the soil entry angle and digging depth of the double-auger digging mechanism, thereby realizing the functions of breaking and loosening the soil and digging scallions. Both the double-auger digging mechanism and the controllable adjustment mechanism are connected to the hydraulic power system, which provides the operating power.

[0027] Specifically, the double-auger digging mechanism includes a digging shovel 1, a shovel bar 2, a double auger 3, an auger rod 4, and a lower fixing plate 5. Two shovel bars 2 and two auger rods 4 are provided, with the two shovel bars 2 and the two auger rods 4 parallel to each other. One end of each shovel bar 2 is fixedly connected to the digging shovel 1, and the other end is fixedly connected to the lower fixing plate 5. The ends of each auger rod 4 near the digging shovel 1 are respectively fixedly connected to the double auger 3.

[0028] The blade rod 2 and the auger rod 4 are fixedly connected by a connecting mechanism 11. The connecting mechanism 11 includes a connecting rod and a bushing. The bushing is fixedly connected to one end of the connecting rod. A bearing is provided inside the bushing. The bushing is rotatably connected to the auger rod 4 through the bearing. The end of the connecting rod away from the bushing is rotatably connected to the blade rod 2, so that the connecting mechanism 11 can connect and fix the blade rod 2 without affecting the rotation of the double auger 3.

[0029] The hydraulic power system includes a hydraulic motor 6 and a hydraulic cylinder 7. The output shaft of the hydraulic motor 6 is connected to the auger rod 4. The hydraulic motor 6 drives the auger rod 4 and the double auger 3 to rotate. The end of the hydraulic motor 6 away from the auger rod 4 is fixed on the lower fixed pad 5.

[0030] The controllable adjustment mechanism includes a bottom bracket 8 and a telescopic sleeve 9. One end of the telescopic sleeve 9 is hinged to the bottom bracket 8, and the other end is fixedly connected to the frame 12. The bottom bracket 8 is welded and fixed to the lower fixed pad 5.

[0031] The telescopic sleeve 9 includes an inner sleeve and an outer sleeve. The outer sleeve is fitted outside the inner sleeve, and the inner sleeve and the outer sleeve can slide relative to each other. A groove is provided on the side wall of the outer sleeve, and a bolt is provided in the groove. The bolt passes through the groove and is threaded to the inner sleeve. The inner and outer sleeves can slide relative to each other, thereby adjusting the length of the telescopic sleeve 9. The length of the telescopic sleeve 9 can be fixed by tightening the bolt, thereby adjusting the soil penetration depth of the double auger 3 and the digging shovel 1 using the telescopic sleeve.

[0032] The telescopic sleeve 9 is provided with a connecting inclined plate 10, which is fixed on the inner cylinder. One end of the hydraulic cylinder 7 is hinged to the connecting inclined plate 10, and the other end is hinged to the shovel rod 2, forming a sliding adjustment mechanism, thereby adjusting the soil entry angle of the double auger 3 and the digging shovel 1.

[0033] Specifically, since the telescopic sleeve 9 is hinged to the bottom bracket 8, and the bottom bracket 8 is connected to the blade rod 2 through the lower fixed pad 5, and the blade rod 2 is hinged to the telescopic sleeve 9 through the hydraulic cylinder 7 and the connecting inclined plate 10, when the telescopic sleeve 9 extends or shortens, the blade rod 2 rotates around the hinge point between the telescopic sleeve 9 and the bottom bracket 8, thereby adjusting the soil entry angle of the double-hinged auger 3 and the digging shovel 1.

[0034] This invention utilizes a double-auger digging device installed at the bottom of the chassis 12. With the cooperation of the double-auger 3, the digging shovel 1, and the connecting mechanism 11, the double-auger 3 is driven to rotate by a hydraulic motor 6. The power is provided by the hydraulic motor 6. First, the double-auger 3 drills into the soil to break and loosen it, effectively reducing digging resistance. Then, the digging shovel 1 digs the scallions. The digging shovel's entry angle is adjustable between 10° and 30°. The front end of the digging shovel 1 maintains a small entry angle to cut the soil. The rear end of the digging shovel 1 is designed with a certain angle of folding to facilitate the digging of the scallions. The hydraulic cylinder 7 is connected to the shovel rod 2 via a hinge, converting pressure energy into the extension and retraction of the rod while also allowing the double-auger 3 and the digging shovel 1 to swing at a certain angle. Furthermore, the connecting mechanism 11 connects and fixes the shovel rod 2 without affecting the rotation of the double-auger 3. Meanwhile, the excavation mechanism is hinged by the telescopic sleeve 9 and the blade rod 2 is hinged by the hydraulic cylinder 7, which allows the overall excavation mechanism to freely and flexibly control the soil entry angle and depth, increasing the machine's flexibility.

[0035] Example 2

[0036] This embodiment provides a method for digging up scallions, utilizing a scallion digging device as described in Embodiment 1, including the following steps:

[0037] In operation, the hydraulic motor is first started. The hydraulic motor drives the double augers to rotate in opposite directions through the auger rod, interlacing to break and loosen the soil, effectively reducing digging resistance. At the same time, the digging shovel is used to cut the soil and dig for the scallions. The front end of the digging shovel can cut the soil, and the rear end is designed to fold at a certain angle to facilitate the digging of scallions. During the digging process, the digging mechanism's entry angle and depth are adjusted by the hydraulic cylinder and telescopic sleeve, increasing the machine's flexibility.
