Description

Technical Field

[0001] The invention relates to the technical field of crop picking, in particular to a high-efficiency lotus root picking machine. Background Art

[0002] Lotus root has rich nutritional value and certain medicinal value, and is known as the "ginseng in water". The traditional way of collecting lotus roots mainly relies on manual labor, that is, first most of the water in the lotus field is pumped out, and then the lotus roots are dug with manual tools such as shovels and sickles, and finally screened and cleaned manually. This collection method is cumbersome, inefficient, labor-intensive, and extremely physically demanding for workers.

[0003] In order to overcome the shortcomings of traditional collection methods, various lotus root harvesting machines have gradually appeared on the market. These lotus root harvesting machines usually use water to flush the mud in the lotus field, so that the lotus roots in the mud leak out to the surface to improve the efficiency of lotus root harvesting. However, since lotus roots have many branches and the mud in the lotus field is hard, the connection strength between lotus roots and mud is very high. When flushing the lotus field with water, only the mud on the surface of the lotus roots can be flushed, and the lotus roots and mud are still difficult to separate, and manual digging is required. At the same time, when flushing the mud, the washed mud mixes with water to form muddy turbid liquid, which makes it difficult to identify the lotus roots under the turbid liquid, and the efficiency of lotus root harvesting is low.

[0026] refer to Figure 1-8 A high-efficiency lotus root harvester includes a fuselage 1, a moving mechanism 2, a bucket 3, a transport line 4, a flushing device 5, a scraper assembly 6, a lifting device 7, a collecting frame 8, and a cockpit 9. The fuselage 1 serves as the main structure of the entire lotus root harvester and carries various functional components. An engine 11 is provided on one side of the bottom of the fuselage 1 to provide power for the entire lotus root harvester. The engine 11 can be a diesel engine. The moving mechanism 2 is arranged at the bottom of the fuselage 1, and can drive the fuselage 1 to move freely in the lotus field, realize flexible operation and full coverage of the lotus field, avoid the situation of missing lotus roots, thereby avoiding the waste of lotus roots and economic losses. The bucket 3 is arranged on one side of the fuselage 1, and is used to shovel up the mud with lotus roots. The transportation line 4 is arranged at one end of the fuselage 1, and the length of the transportation line 4 can be greater than the length of the fuselage 1, and is used to smoothly and continuously transport the lotus roots or other materials excavated from the bucket 3 to the side of the fuselage 1 away from the bucket 3 for subsequent processing. At the same time, the bucket 3 shovels up the lotus roots together with the soil, and transports the soil with lotus roots to the tail of the fuselage 1 through the transportation line 4. In this process, the lotus roots and the soil can be naturally loosened without damaging the lotus roots, which is convenient for subsequent flushing to separate the soil from the lotus roots.

[0027] The flushing device 5 is arranged on the fuselage 1, and its position is convenient for flushing the lotus roots on the transport line 4. Through high-pressure water flow or other flushing methods, the soil and impurities on the surface of the lotus roots can be effectively removed to separate the lotus roots from the soil, thereby realizing the picking of the lotus roots. The scraper assembly 6 is arranged between the bucket 3 and the flushing device 5, and is located above the transport line 4. A scraping area is formed between the scraper assembly 6 and the transport line 4. The lotus roots or other materials in the scraping area are scraped upward by the scraper assembly 6 to ensure that the lotus roots are stably transmitted under the action of the transport line 4. The collection frame 8 is arranged on the side of the fuselage 1 away from the bucket 3, for receiving the washed lotus roots. The collection frame 8 may be provided with a picking area, and the washed lotus roots are manually placed in the collection frame 8. The cockpit 9 is arranged on the side of the fuselage 1 close to the bucket 3, providing the operator with a comfortable and safe working environment and a wide working field, so that the operator can conveniently control the various functions of the lotus root harvester in the cockpit 9 to realize efficient and accurate lotus root harvesting operations. The cockpit 9 is a prior art and will not be described here.

[0028] In some embodiments, the mobile mechanism 2 includes a travel motor 23, two crawler assemblies 21, and a steering wheel 22. The travel motor 23 is arranged at the bottom of the body 1, and can provide the moving power for the mobile mechanism 2. In order to enhance the mobility of the lotus root harvester in complex terrain, the two crawler assemblies 21 are symmetrically arranged on the side of the body 1 close to the bucket 3, and are respectively located at both ends of the body 1. The crawler assembly 21 is connected to the travel motor 23 by transmission. The travel motor 23 can be a hydraulic motor. The travel motor 23 can be connected to the engine 11 through an oil pump. The engine 11 drives the oil pump to provide high-pressure oil. The high-pressure oil is connected to the travel motor 23 through a pipeline and a control switch. The travel motor 23 drives the crawler of the crawler assembly 21 to travel. This is a prior art and will not be repeated here. In addition, in order to improve the steering flexibility of the lotus root harvester, the two steering wheels 22 are symmetrically located on the side of the body 1 away from the bucket 3. Through the rotation of the steering wheel 22, the lotus root harvester can realize steering operation to adapt to various working environments.

[0029] In some embodiments, the transport line 4 includes a transport frame 41, multiple transport components 42, and a transport rod chain 43. The transport frame 41 serves as a supporting structure and is firmly disposed at one end of the fuselage 1. A bucket 3 is disposed on one side of the transport frame 41. Multiple transport components 42 are disposed on the transport frame 41. The transport rod chain 43 is transmission-connected to the multiple transport components 42. The rotation of the multiple transport components 42 drives the transport rod chain 43 to rotate, thereby transporting the material on the transport line 4 from the side close to the bucket 3 to the side away from the bucket 3, thereby realizing the transportation of lotus roots with soil on the transport line 4.

[0030] In some embodiments, the transport assembly 42 includes a transport motor 421, a rotating rod 422, and two transport rollers 423. The transport motor 421 is arranged on the transport frame 41 to provide power for the transport assembly 42. The transport motor 421 can be a hydraulic motor, which can be connected to the engine 11 through an oil pump. The engine 11 drives the oil pump to provide high-pressure oil. The high-pressure oil is connected to the transport motor 421 through a pipeline and a control switch to provide power output of the transport motor 421. The rotating rod 422 is connected to the output shaft of the transport motor 421, and the power generated by the transport motor 421 can be transmitted to the subsequent transmission components. The two transport rollers 423 are respectively sleeved on the rotating rod 422 and establish a transmission connection with the transport rod chain 43. Through the rotation of the transport roller 423, the transport rod chain 43 can be driven to move continuously, thereby realizing the stable transmission of the material. The transport assembly 42 can use the power provided by the transport motor 421, through the effective cooperation of the rotating rod 422 and the transport roller 423, to drive the transport rod chain 43 to perform efficient and stable material transmission, which provides a strong guarantee for the smooth operation of the entire system.

[0031] In some embodiments, the transport rod chain 43 may include multiple transport rods, which may be metal rods. The two ends of the multiple transport rods may be connected by two rubber belts. The transport roller 423 may be provided with multiple teeth distributed in a ring shape on the surface. The teeth are inserted into the gap between two adjacent transport rods, so that the transport rod is pushed to move by the rotation of the teeth, thereby realizing the rotation of the transport rod chain 43, and then realizing the transportation of lotus roots with soil. At the same time, the gaps between the transport rods can facilitate the diversion of soil and lotus roots when the flushing device 5 flushes the lotus roots with soil, and then the soil and lotus roots are mixed with water and fall into the lotus field from the gaps, which can reduce the consumption of lotus field soil during lotus root harvesting and ensure the fertility of lotus field soil.

[0032] In some embodiments, the transport component 42 also includes multiple supporting wheels 424, which are arranged at the bottom of the transport rod chain 43 and fit with the bottom surface of the transport rod chain 43. The supporting wheels 424 can increase the supporting points of the transport rod chain 43, thereby further improving the stability of the transport component 42 during transportation and improving the carrying capacity of the transport line 4.

[0033] In some embodiments, the transport rack 41 includes a scraping section 411, a flushing section 412, and a picking section 413. The scraping section 411 is arranged on the side of the transport line 4 close to the bucket 3. The scraping section 411 is connected to the bucket 3. After the bucket 3 scoops up the lotus root with soil, it can be smoothly transferred to the next processing stage. Through the cooperation between the bucket 3 and the scraping section 411, the lotus root and the soil can be loosened while ensuring the integrity of the lotus root, which is convenient for the subsequent separation of the soil and the lotus root. A scraper assembly 6 is provided above the scraping section 411. With the assistance of the scraper assembly 6, the lotus root with soil can be lifted and maintained in continuous and stable transportation during transportation. The flushing section 412 follows the scraping section 411 and is located on the side of the scraping section 411 away from the bucket 3. A flushing device 5 is provided above the flushing section 412. The lotus root with soil transported on the flushing section 412 is flushed with water by the flushing device 5 to remove the soil on the surface of the lotus root, so as to separate the lotus root from the soil. Discharge troughs are provided at both ends of the scraping section 411 and the flushing section 412. The bottom of the discharge trough is lower than the top plane of the transport rod chain 43, and the height of the discharge trough is less than the height of the lotus root, so as to facilitate the discharge of the mud-water mixture from both sides of the transport frame 41. The flushing section 412 can form a certain angle with the horizontal plane, so that the mud on the flushing section 412 can be discharged faster under the impact of the water flow and its own gravity; the picking section 413 is located on the side of the flushing section 412 away from the bucket 3. In the picking section 413, the operator or automated equipment can further screen and classify the cleaned materials to ensure the quality and consistency of the final product and realize the collection of lotus roots.

[0034] In some embodiments, a lifting device 7 is further included, and the lifting device 7 includes two lifting units and a connecting rod 74. The two lifting units are symmetrically arranged between the top of the scraping section 411 and the top of the flushing section 412. The bottom of the scraping section 411 is hinged to the bottom of the flushing section 412. The connecting rod 74 is axially connected to the top of the scraping section 411, and the two ends of the connecting rod 74 are respectively hinged to the two lifting units near the side of the scraping section 411. The two lifting units can drive the connecting rod 74 to rotate, thereby realizing the scraping section 411 in the flushing The rotation on segment 412 realizes the shoveling depth of the bucket 3 in the lotus field, so as to shovel the lotus roots and the soil of appropriate thickness. Because when the shoveling depth of the bucket 3 is large, the thickness of the soil shoveled by the bucket 3 is large, which will increase the difficulty of subsequent separation of the soil and the lotus roots, and may easily lead to the lotus roots and the soil not being separated in time, resulting in the leakage of the lotus roots. When the shoveling depth of the bucket 3 is small, the thickness of the soil shoveled by the bucket 3 is small, so that the soil does not provide sufficient protection for the lotus roots, which may easily lead to the breakage of the lotus roots and reduce the integrity of the lotus root picking.

[0035] Specifically, the lifting unit includes a lifting seat 71, a lifting member 72 and an adjusting groove 73. The lifting seat 71 is arranged on the top side of the flushing section 412. One end of the lifting member 72 is hinged to the lifting seat 71, and the other end of the lifting member 72 is hinged to the connecting rod 74. Adjustment grooves 73 are arranged on both side walls of the top of the flushing section 412. A connecting rod 74 runs through the adjusting groove 73. The connecting rod 74 can slide in the adjusting groove 73. The adjusting groove 73 can be an arc groove. The lifting member 72 can be a hydraulic cylinder. The hydraulic cylinder oil can be connected to the engine 11. The engine 11 increases the power. Through the drive of the lifting member 72, the connecting rod 74 slides in the adjusting groove 73, so that the scraping section 411 rotates on the flushing section 412, and then the descending height of the bucket 3 is adjusted, so that it can be adjusted according to different picking environments to achieve complete picking of lotus roots.

[0036] In some embodiments, the flushing device 5 includes a water pump 51, a filter component, and a flushing component 52. The water pump 51 is disposed at the bottom of the fuselage 1, and can absorb water from the lotus field to provide a stable water source for subsequent flushing of lotus roots. The filter component is connected to the water pump 51, and can filter the water in the lotus field to improve the cleanliness of the water entering the water pump 51, thereby preventing debris in the water from affecting the operation of the flushing device 5. The flushing component 52 is disposed above the transport line 4. The flushing component 52 may include multiple high-pressure nozzles, which are connected to the water pump 51. The water outlet direction of the high-pressure nozzle is toward the transport line. Water is absorbed by the water pump 51 and transported to the flushing component 52, thereby achieving comprehensive and effective flushing of the materials on the transport line 4.

[0037] In some embodiments, the scraper assembly 6 includes multiple scraper wheels 62, scraper belts 63, and multiple scraper plates 61. The transport frame 41 provides stable support for the scraper assembly 6. The multiple scraper wheels 62 are arranged on the side of the transport frame 41 close to the bucket 3, and can be arranged on the scraping section 411 and are connected to the transport assembly 42 in a transmission manner. The transport assembly 42 provides power for the rotation of the scraper wheels 62. The scraper belt 63 is connected to the multiple scraper wheels 62 in a transmission manner. The scraper belt 63 and the transport assembly 42 form a scraping area close to the bucket 3. Multiple scraper plates 61 are arranged on the scraper belt 63 at equal intervals. The multiple scraper wheels 62 are driven to rotate by the transport assembly 42, thereby driving the scraper belt 63 to rotate, and then driving the scraper plate 61 to rotate, so that the material in the scraping area is comprehensively and effectively scraped and transported. Through the rotation of the scraper plate 61, the scraper can cut into the mud to strengthen the conveying force of the lotus root with mud entering the scraping section 411 from the bucket 3, and prevent the thinner mud from slipping.

[0038] In some embodiments, the scraper wheel 62 and the transport roller 423 can be connected through a sprocket and chain structure transmission connection, which can realize synchronous and reverse rotation of the scraper wheel 62 and the transport roller 423, and then realize the same speed rotation of the scraper belt 63 and the transport rod chain 43, so as to realize the enhanced effect of the scraper assembly 6 on the transportation of lotus roots with soil on the transport rod chain 43, avoid different rotation speeds between the scraper belt 63 and the transport rod chain 43, and reduce the transportation effect of the transport rod chain 43 on the lotus roots with soil.

[0039] The specific working principle is as follows: Lotus roots generally grow in the soil 15 to 20 centimeters deep from the soil surface. The operator controls the engine 11 to start in the cockpit 9, and adjusts the depth of the bucket 3 through the lifting device 7 to make it descend to a depth of 15 to 20 centimeters in the soil to dig lotus roots and the accompanying soil. At the same time, the engine 11 provides power to drive the body 1 to move forward in the lotus field through the crawler assembly 21. The steering wheel 22 provides steering force under the action of the steering motor to achieve turning during operation.

[0040] As the lotus root harvester moves forward, the bucket 3 continuously scoops up the lotus roots and the accompanying soil, and the lotus roots and the accompanying soil are squeezed by the newly scooped soil and move toward the scraping section 411. At this time, the transport motor 421 drives the rotating rod 422 to rotate under the hydraulic action of the engine 11, and the rotating rod 422 drives the transport roller 423 to rotate, thereby rotating the transport rod chain 43, and then driving the soil blocks and the lotus roots in the soil to be transported toward the picking section 413.

[0041] During this process, the scraper wheel 62 rotates, driving the scraper plate 61 to rotate through the scraper belt 63. When the scraper plate 61 rotates to the scraping and conveying area, the scraper plate 61 will slap the lotus root with mud and cut into the mud, reducing the connection strength between the lotus root and the soil. Multiple transport intervals are formed by multiple scraper plates 61, so that the scraper plates 61 share part of the gravity of the lotus root with mud, thereby improving the carrying capacity of the transport line 4 and enhancing the stability of the lotus root with mud during transportation.

[0042] When the mud and lotus roots are transferred to the flushing section 412, the water in the lotus field is filtered by the filter assembly under the suction force of the water pump 51, and the water is sent to multiple high-pressure nozzles. The high-pressure nozzles form a water gun array, and the high-pressure water flow ejected is aimed at the lotus roots with mud. The mud on the lotus roots is washed away by the high-pressure water flow. The mixture of mud and water flows out along the gaps in the discharge troughs at both ends of the transport frame 41 and the transport bar chain 43, and falls into the lotus field, realizing the recycling of water resources. The lotus roots separated from the mud continue to be transferred backward to the selection section 413 under the action of the transport line 4, and the lotus root picker located in the selection section 413 picks the lotus roots into the collection frame 8. The debris and remaining mud left on the transport bar chain 43 continue to be transferred backward, and finally fall into the lotus field, which can reduce the loss of mud in the lotus field and maintain the fertility of the lotus field.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
