Description

Technical Field

[0001] The invention relates to the technical field of vegetable harvesting, and in particular to a fungus harvester. Background Art

[0002] Black fungus, also known as black vegetable, fungus, and cloud fungus, belongs to the Auriculariaceae family and the genus Auricularia. It is a precious colloid fungus used for both medicine and food in my country, and is also recognized as a health food in the world. Black fungus is grown in Northeast my country, North China, Central South, Southwest China and coastal provinces in China. According to modern scientific analysis, black fungus contains substances such as plant collagen and fungus polysaccharides. The content of protein, vitamins and iron in dried black fungus is very high. Its protein contains a variety of amino acids, especially lysine and leucine.

[0003] At present, when growing black fungus, the fungus species are placed on a cylindrical mushroom stick. When the black fungus matures, it also grows in a circle around the mushroom stick. When the black fungus is harvested, it is usually harvested manually. However, manual harvesting is not only time-consuming and labor-intensive, but also easy to miss the best harvesting period of black fungus. The use of mechanical farm tools for harvesting black fungus will improve the efficiency of harvesting. However, there are few special equipment for harvesting black fungus on the market. There are only some harvesters improved from other harvesting machines. They mainly use an annular blade, which is put on the mushroom stick and cuts downwards when in use. However, the annular blade of this equipment cannot completely fit the mushroom stick during use, so that the mature black fungus on the mushroom stick cannot be completely harvested when completing a downward cut. It needs to be repeated several times. At the same time, part of the black fungus may be cut from the middle near the mushroom stick, which damages the black fungus, affects the quality of the black fungus and affects the secondary growth of the black fungus.

On the other hand, the blade 22 can be made to harvest the fungus along the edge of the mushroom stick, avoiding damage to the fungus and affecting its quality, and also avoiding affecting the secondary growth of the fungus. When in use, the driving structure 4 can drive the elastic member 3 to rise and fall in the cylinder 1, thereby driving the cutting structure 2 to rise and fall in the cylinder 1 to complete the harvesting.

[0048] In order to adapt to the shape of the mushroom stick, the housing 21 is configured to be retractable in this embodiment. Figure 2As shown, further, the housing 21 includes: a telescopic ring 211 and an arc plate 212. The two telescopic rings 211 are coaxially arranged, one of the telescopic rings 211 is located below the other telescopic ring 211, and the two telescopic rings 211 are arranged at intervals from top to bottom. One end of the elastic member 3 is connected to the outer side wall of one of the telescopic rings 211, as shown in FIG. Figure 1 , the elastic member 3 is connected to the side wall of the telescopic ring 211 above; a plurality of arc plates 212 are arranged between the two telescopic rings 211 in an annular array, the arc plates 212 are consistent with the curvature of the telescopic rings 211, the top and bottom ends of the arc plates 212 are respectively fixed to the side walls of the two telescopic rings 211, and a plurality of blades 22 are respectively arranged on the plurality of arc plates 212 in a one-to-one correspondence. In this embodiment, a plurality of arc plates 212 are arranged to avoid affecting the telescopic ring 211. In this embodiment, the structure of the housing 21 can be telescopic, which is convenient for adapting to the shape and size of the mushroom stick and has a wider range of applications.

[0049] This embodiment provides a specific method of a telescopic ring 211, such as Figure 3 As shown, further, the telescopic ring 211 includes: a first arc rod 213, a second arc rod 214, and an annular limiting plate 215. The first arc rod 213 is a hollow structure, one end of the first arc rod 213 is closed, and the other end of the first arc rod 213 is open, and the first arc rod 213 forms a hollow rod body; one end of the second arc rod 214 is hinged to the closed end of the first arc rod 213, and the hinge of the second arc rod 214 and the first arc rod 213 can be achieved by a pin or a torsion spring, and the other end of the second arc rod 214 is sleeved on the open end of the first arc rod 213, that is, a part of the second arc rod 214 is inserted into the first arc rod 213, and the length of the second arc rod 214 inserted into the first arc rod 213 can be adjusted during use. The first arc rod 213 and the second arc rod 214 can be made of plastic or other elastic plastics The second arc rod 214 and the first arc rod 213 are made of a material, and the combination of the second arc rod 214 and the first arc rod 213 is annular; two annular limiting plates 215 are provided, wherein one annular limiting plate 215 is arranged at one end of the second arc rod 214 which is sleeved inside the first arc rod 213, and the other annular limiting plate 215 is fixed to the open end of the first arc rod 213, and the second arc rod 214 is penetrated in the annular limiting plate 215, when the end of the second arc rod 214 moves to the open end of the first arc rod 213, the two annular limiting plates 215 contact each other, and the second arc rod 214 will not be separated from the first arc rod 213. By providing two annular limiting plates 215, the second arc rod 214 can be prevented from slipping out of the first arc rod 213. When in use, the second curved rod 214 and the first curved rod 213 can be held to stretch and contract to adjust the length of the second curved rod 214 located on the first curved rod 213, so that the blade 22 is in close contact with the side wall of the mushroom stick, which is convenient for harvesting the fungus along the edge of the mushroom stick, avoiding damage to the fungus and affecting its quality, and also avoiding affecting its secondary growth.

[0050] like Figure 4 As shown, further, two elastic members 3 are provided, and the two elastic members 3 are symmetrically arranged, wherein the end of one elastic member 3 is connected to the outer side wall of the first arc rod 213, and the end of the other elastic member 3 is connected to the outer side wall of the second arc rod 214, that is, the two elastic members 3 are respectively connected to the first arc rod 213 and the second arc rod 214, which will not affect the extension and retraction of the telescopic ring 211. At the same time, this is also to utilize the rebound force of the elastic member 3 to insert the second arc rod 214 into the first arc rod 213 so that the length is just matched with the circumference of the mushroom stick. This embodiment provides a specific method of an elastic member 3, and the elastic member 3 includes: a first telescopic rod 31, a spring 32, and a fixing block 33. One end of the first telescopic rod 31 is connected to the side wall of the first arc rod 213 or the second arc rod 214, and the first telescopic rod 31 has a telescopic function. The other end of the first telescopic rod 31 is connected to the side wall of the cylinder 1. The driving structure 4 is used to drive the first telescopic rod 31 to rise and fall in the cylinder 1. The lifting and lowering of the first telescopic rod 31 drives the lifting and lowering of the telescopic ring 211 to achieve the function of harvesting the fungus on the mushroom stick; the spring 32 is sleeved on the first telescopic rod 31, and the end of the first telescopic rod 31 connected to the cylinder 1 is provided with a fixing block 33, one end of the spring 32 is fixed to the side wall of the first arc rod 213 or the second arc rod 214, and the other end of the spring 32 is fixed to the fixing block 33. When in use, the spring 32 is in a compressed state. The structure of the elastic member 3 in this embodiment utilizes the rebound force of the spring 32 stretched toward both ends to make the first telescopic rod 31 extend outward, so as to push the inner side walls of the first arc rod 213 and the second arc rod 214 against the side walls of the mushroom stick, so as to facilitate the blade 22 to harvest along the root of the fungus and avoid damage to the fungus.

[0051] Example 2

[0052] As a further improvement on Example 1, Figure 2As shown, in order to allow the blade 22 to cut against the mushroom stick, the blade 22 further includes: a connecting piece 221 and a cutting piece 222. The connecting piece 221 is horizontally arranged at one end of the arc plate 212, and the connecting piece 221 is connected to the inner side wall of the arc plate 212; the cutting piece 222 is obliquely arranged at the end of the connecting piece 221 away from the arc plate 212, and the end of the cutting piece 222 connected to the connecting piece 221 is higher than the other end of the cutting piece 222, and the end of the cutting piece 222 away from the connecting piece 221 is a tip, and the tip is the cutting end, that is, the cutting end of the cutting piece 222 is tilted downward, and the end of the cutting piece 222 away from the connecting piece 221 (that is, the tip) is flush with the inner side wall of the telescopic ring 211, when the elastic member 3 makes the telescopic ring 211 abut against the side wall of the mushroom stick, the tip of the cutting piece 222 can also abut against the side wall of the mushroom stick, so that the fungus can be cut along the edge of the mushroom stick to avoid damaging the fungus. The structure of the blade 22 in this embodiment allows the cutting end of the cutting piece 222 to abut against the side wall of the mushroom stick, so that the fungus can be cut along the edge of the mushroom stick to avoid damaging the fungus and affecting its quality. At the same time, the cutting end of the cutting piece 222 is tilted downward, so that when the driving structure 4 drives the first telescopic rod 31 downward, the cutting piece 222 has a downward force to cut the fungus.

[0053] Furthermore, the angle between the connecting piece 221 and the cutting piece 222 is 115°-150°, which limits the downward tilt angle of the cutting piece 222. Within this range, the fungus can be better cut off.

[0054] Among them, other structures of this embodiment are consistent with those of embodiment 1, and are just optimizations made to embodiment 1.

[0055] Example 3

[0056] As a further improvement on Example 1, this example provides a specific method of a driving structure 4, and further, the driving structure 4 includes: a thread groove and a driving member. The thread groove is provided on the inner wall of the cylinder 1, and the thread groove is provided along the height direction of the cylinder 1, and the fixing blocks 33 at the ends of the two first telescopic rods 31 are clamped in the thread groove, and the fixing blocks 33 are slidably connected with the thread groove, and the fixing blocks 33 can slide in the thread groove along the thread groove; the driving member has an output end, and the output end of the driving member is connected to the fixing block 33, and the driving member is used to drive the fixing block 33 to slide in the thread groove. The working principle of the driving structure 4 in this embodiment is as follows: the driving member drives the fixed block 33 to slide in the thread groove, driving the first telescopic rod 31 and the telescopic ring 211 to slide in the thread groove accordingly. Because they rotate and rise and fall along the thread groove, the telescopic ring 211 and the blade 22 can be driven downward to cut the fungus on the mushroom stick. At the same time, the telescopic ring 211 and the blade 22 can also rotate downward, which is convenient for rotating to cut the fungus on the mushroom stick, and the fungus in a circle on the mushroom stick can be harvested to avoid incomplete cutting and the need for rework.

[0057] like Figure 5 As shown, this embodiment provides a specific mode of a driving member. Further, the driving member includes: a support plate 41, an annular groove 42, a second telescopic rod 43, a motor, a rotating shaft, a gear 44, and an annular rack 45. The support plate 41 is annular and is arranged at the bottom end of the cylinder 1. When in use, the mushroom stick is sleeved in the support plate 41. At the same time, a net bag or a cloth bag or other structure can be arranged on the bottom surface of the support plate 41, and the fungus cut from the mushroom stick can fall into the cloth bag for collection, avoiding the collection by the harvesters. An annular groove 42 is provided on the top surface of the support plate 41, and the annular groove 42 is also provided on the top surface of the support plate 41 along the annular path of the support plate 41; the second telescopic rod 43 is vertically arranged, and the second telescopic rod 43 has the function of telescoping. The top end of the second telescopic rod 43 is rotatably connected to the side wall of the telescopic ring 211 located below, and the rotatable connection can be achieved through a bearing. When the second telescopic rod 43 rotates, it will not drive the telescopic ring 211 to rotate; the motor is arranged at the bottom end of the second telescopic rod 43, and the output shaft of the motor is vertically arranged, and the output shaft of the motor is connected to a rotating shaft; the gear 44 is fixed on the rotating shaft; the annular rack 45 is mounted on the inner wall of the annular groove 42, and the annular rack 45 is meshed with the gear 44. The working principle of the driving member in this embodiment is as follows: the motor works to drive the rotating shaft to rotate, so that the gear 44 thereon rotates synchronously, and the gear 44 is meshed with the annular rack 45. Therefore, when the gear 44 rotates, the gear 44 can also move on the annular rack 45, thereby driving the rotating shaft and the second telescopic rod 43 to move on the annular rack 45, so that the telescopic ring 211 rotates, and the first telescopic rod 31 and the fixed block 33 are driven to rotate while rotating in the thread groove. At the same time, the second telescopic rod 43 is also lifted and lowered synchronously with the lifting and lowering of the telescopic ring 211, and will not affect the rotation and lifting movement of the telescopic ring 211.

[0058] Among them, other structures of this embodiment are consistent with those of embodiment 1, and are just optimizations made to embodiment 1.

[0059] The advantages of the present invention are that, firstly, a cutting structure is arranged in the cylinder body of the device, and the annular cutting structure is mounted on the mushroom stick when in use, so that the fungus on a circle on the mushroom stick can be harvested; secondly, an elastic member is arranged between the shell of the cutting structure and the cylinder body, and the elastic force of the elastic member can make the blade on the inner wall of the shell body close to the mushroom stick. On the one hand, it can adapt to the shape of the mushroom stick, and the fungus on the mushroom stick can be harvested at one time during harvesting, avoiding repeated harvesting and improving the harvesting efficiency of the fungus; on the other hand, the blade can be made to harvest the fungus along the edge of the mushroom stick, avoiding damage to the fungus and affecting its quality, and also avoiding affecting the secondary growth of the fungus. When in use, the driving structure can drive the elastic member to rise and fall in the cylinder body, thereby driving the cutting structure to rise and fall in the cylinder body to complete the harvesting.
