Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery and equipment, in particular to a small electric hole enlarging machine. Background Art

[0002] During the growth of Tremella, due to the small size of the inoculation port, it is not enough for the subsequent growth of Tremella, and it is necessary to expand the hole to expand the hole. In domestic production, a utility knife is generally used to expand the hole manually, resulting in inconsistency and instability in the size and shape of the incision. If the incision size is too small, the hole expansion effect cannot be achieved. If the incision size is too large, in addition to the Tremella mushroom stick being easily contaminated and affecting the yield or even scrapping, it may also cause the Tremella to grow and mature. The contact area between the Tremella and the culture medium is too large, resulting in the difficulty and workload of removing the Tremella ear base when the Tremella is harvested. Therefore, the existing artificial hole expansion will affect the yield and quality of Tremella. Utility Model Content

[0003] In order to solve the above problems in the prior art, the utility model provides a small electric hole enlarging machine, which can ensure that the incision formed by the hole enlarging has a regular shape and stable size.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] In a first aspect, the utility model provides a small electric hole expanding machine, comprising a main frame, a holding mechanism, a positioning mechanism and a plurality of hole expanding mechanisms, wherein the holding mechanism, the positioning mechanism and the hole expanding mechanism are all located on the main frame;

[0006] Each group of the hole expansion mechanism comprises a driving mechanism, a blade mounting frame and a blade, wherein the driving mechanism is connected to the blade mounting frame, the blade is slidably mounted on the blade mounting frame and fixed by a locking screw, and a plurality of blades are evenly distributed on the blade mounting frame;

[0007] The positioning mechanism includes an upper surface limiting device, a pressing plate and a clamping mechanism. The number of the upper surface limiting devices is consistent with the number of groups of the hole expanding mechanism. The upper surface limiting device is arranged on the side of the main frame where the blade is located and the side away from the main frame is a plane. The lowest point of the blade in the working state is lower than the lowest point of the upper surface limiting device. The blade is located in the middle hollow area of ​​the upper surface limiting device. The driving mechanism drives the blade to rotate, and the blade is used to cut the film on the Tremella fuciformis stick to form an incision.

[0008] The clamping mechanism includes a limit mounting piece, a limit vertical rod, a limit block, a transition plate and a cross plate, wherein the limit mounting piece is respectively installed with a group on both sides of the width direction of the main frame and arranged upward, each group of limit mounting pieces is rotatably connected with a limit vertical rod, one end of the two limit vertical rods close to the limit mounting piece is rotatably connected with a transition plate, the two ends of the cross plate are respectively rotatably connected with a transition plate, the end of the limit vertical rod away from the limit mounting piece is provided with the limit block, the pressing plate is connected to the cross plate, and the two limit vertical rods drive their respective limit blocks to approach or move away from each other when the pressing plate moves up and down, and the limit blocks are used to clamp the sides of the Tremella fuciformis sticks.

[0009] Optionally, the driving mechanism includes a motor and a reducer, the motor is electrically connected to the reducer, and the blade mounting bracket is fixedly mounted on the shaft of the reducer.

[0010] Optionally, the reducer is installed in the middle hollow area of ​​the upper surface limiting device.

[0011] Optionally, three groups of the hole expanding mechanisms are provided, one group of the clamping mechanisms is provided between two adjacent groups of the hole expanding mechanisms, and the pressing plate is connected to the transverse plates in the two groups of the clamping mechanisms at the same time.

[0012] The beneficial effects of the utility model are:

[0013] (1) The incision formed by the hole expansion of the utility model has a regular shape and stable size.

[0014] The existing artificial hole expansion is elliptical, and the hole expansion mouth is long or short. The hole expansion mouth that is too long will not only cause the Tremella to contact too much with the culture medium of the mushroom stick, resulting in the Tremella being contaminated, thus affecting the yield or even scrapping; but also will cause the Tremella to produce too many ear bases when harvesting, increasing the work of removing the ear bases, reducing the weight of the effective Tremella, and reducing the income of farmers. The hole expansion mouth that is too short cannot meet the nutrients required for the growth of Tremella, resulting in low Tremella yield and reduced income for farmers. The incision formed by the hole expansion of the utility model has a regular shape and stable size. By changing the cutting size of the hole expansion mechanism, the hole can be expanded to an incision size suitable for the healthy production of Tremella, which is helpful for the Tremella appearance and improves the stability of the good Tremella appearance. It is ultimately beneficial to farmers, bringing them more income and less cost, including the cost of hole expansion and ear base removal.

[0015] (2) The utility model realizes handheld hole enlargement.

[0016] At present, most of the hole expansion workers are middle-aged and elderly female workers who are unable to undertake heavy physical labor. The utility model is light in weight and compact in size, so it can be held by one person with both hands. During the hole expansion stage, the mushroom sticks are stored in layers of steel frames one by one in an orderly interval. Therefore, the mushroom sticks can be expanded directly on the steel frame by hand, without having to take the mushroom sticks out of the steel frame manually and put them back after the hole expansion, which reduces the labor intensity and improves work efficiency. In order to locate the long side of the mushroom stick by eye, the upper surface limit device and the blade mounting frame can be made of materials such as white transparent acrylic plate. Due to the small working space, it is impossible to put in a large continuous hole expansion mechanism. The utility model can easily realize the continuous hole expansion function in a small working space through a simple structural design.

[0017] (3) The utility model can stably, reliably and completely cut the upper surface of the mushroom stick.

[0018] The mushroom stick is a solid object formed by wrapping the internal culture medium with an external membrane. During the rotary cutting process, the cut part of the membrane is in a relaxed state and will warp. If there is no upper surface limiting device to cover the surrounding areas, the cut part of the membrane will drive the uncut membrane to warp, causing the blade to be blocked by the warped membrane during the cutting process, resulting in the membrane being unable to be completely cut. Secondly, the surface of the mushroom stick is an arc-like surface with a high middle and low sides. The height position of the cutting blade is adjusted to adapt to the arc-like surface and fixed with a locking screw after adjustment to achieve complete cutting of the upper surface of the mushroom stick. At the same time, the upper surface limiting device also serves to limit the cutting depth of the blade.

[0019] (4) The utility model can complete the cutting of three holes at one time.

[0020] The utility model uses three motors to drive three groups of blades to achieve one-time cutting of three holes on a mushroom stick, and the height position of the cutting blade can be manually adjusted and fixed with a locking screw after adjustment, thereby ensuring the cutting depth of the three holes on a mushroom stick.

[0029] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0030] Embodiment 1

[0031] Please refer to Figures 1 to 3 A small electric hole enlarging machine comprises a main frame 1, a holding mechanism 2, a positioning mechanism 3 and a plurality of hole enlarging mechanisms 4. The existing Tremella fuciformis stick usually needs to open three incisions, so the hole enlarging mechanism 4 in this embodiment is provided with three groups, so that all the holes on a Tremella fuciformis stick can be cut at one time.

[0032] Reference Figure 1 and Figure 2 It can be seen that the main frame 1 of this embodiment is a plate-shaped body, wherein the holding mechanism 2 , the positioning mechanism 3 and the hole expanding mechanism 4 are all located on the main frame 1 .

[0033] like Figure 1 and 2 It can be seen that the holding mechanism 2 of this embodiment is a handle for the operator to hold.

[0034] like Figure 1 and 2It can be known that the positioning mechanism 3 includes an upper surface limiting device 31, a pressing plate 32 and a clamping mechanism 33. The clamping mechanism 33 includes a limiting mounting member 331, a limiting vertical rod 332, a limiting block 333, a transition plate 334 and a cross plate 335. The limiting mounting member 331 is respectively installed with a group on both sides in the width direction of the main frame 1 and is arranged upward. Each group of limiting mounting members 331 is rotatably connected to a limiting vertical rod 332. The ends of the two limiting vertical rods 332 close to the limiting mounting member 331 are respectively rotatably connected to a transition plate 334. The two ends of the cross plate 335 are respectively rotatably connected to a transition plate 334. A limiting block 333 is set at the end of the limiting vertical rod 332 away from the limiting mounting member 331. The limiting block 333 is used to clamp the side of the Tremella fuciformis stick. The pressing plate 32 is connected to the cross plate 335. Specifically, the pressing plate 32 is mounted on the horizontal plate 335 by screws; the transition plate 334 is mounted between the horizontal plate 335 and the limiting vertical rod 332 by pins; the limiting vertical rod 332 is mounted on the limiting mounting plate by pins to achieve rotation; the limiting block 333 is mounted on the limiting vertical rod 332 by pins to achieve rotation. When the pressing plate 32 moves up and down, the two limiting vertical rods 332 drive their respective limiting blocks 333 to move closer to or away from each other. At this time, the pressing plate 32 is pressed, and the limiting blocks 333 are opened by rotating the horizontal plate 335, the transition plate 334, the limiting mounting plate and the limiting vertical rod 332. After that, the pressing plate 32 is released, and the two limiting blocks 333 move closer to each other, which plays the role of limiting the short side of the mushroom stick.

[0035] Among them, one group of clamping mechanisms 33 is respectively provided between two adjacent groups of hole expanding mechanisms 4 . In this embodiment, two groups of clamping mechanisms 33 are provided, and the pressing plate 32 is connected to the transverse plates 335 in the two groups of clamping mechanisms 33 at the same time.

[0036] like Figures 1 to 3 It can be seen that each set of hole expansion mechanism 4 includes a driving mechanism 41, a blade mounting frame 43 and a blade 42. The driving mechanism 41 includes a motor 411 and a reducer 412. The motor 411 is electrically connected to the reducer 412. The blade mounting frame 43 is fixedly mounted on the shaft of the reducer 412. The reducer 412 is mounted on the middle hollow area of ​​the upper surface limit device 31 by screws.

[0037] In this embodiment, four blades 42 are evenly distributed on the blade mounting frame 43, and the four blades 42 are distributed on the blade mounting frame 43 at intervals of 90 degrees. The blades 42 can be slidably mounted on the blade mounting frame 43 and fixed by locking screws, so that the height adjustment of the blades 42 can be manually adjusted to a suitable position, and then fixed by locking screws. Therefore, the motor 411 drives the four blades 42 of the blade mounting frame 43 to rotate at the same time through the reducer 412, and the blades 42 are used to cut the membrane on the Tremella fuciformis stick to form an incision, so that each blade 42 only needs to rotate 90 degrees, thereby improving the cutting efficiency.

[0038] In this embodiment, the number of upper surface limit devices 31 is consistent with the number of groups of the hole expansion mechanism 4. The upper surface limit device 31 is arranged on the side of the main frame 1 where the blade 42 is located, and the side away from the main frame 1 is a plane and connected to the main frame 1 by screws. The lowest point of the blade 42 in the working state is lower than the lowest point of the upper surface limit device 31. The blade 42 is located in the middle hollow area of ​​the upper surface limit device 31, that is, the rotation range of the blade 42 is all within the middle hollow area of ​​the upper surface limit device 31. Therefore, the upper surface limit device 31 covers the film cut by the blade 42 on all sides to assist the blade 42 to complete the cutting; at the same time, the upper surface limit device 31 also plays a role in limiting the cutting depth of the blade 42.

[0039] Therefore, the working principle of the utility model is as follows:

[0040] (1) The operator holds the holding mechanism 2 with one hand and moves the entire machine to the top of the Tremella fuciformis stick, and then moves it vertically downward. At the same time, the operator presses the pressing plate 32 with the other hand and moves it downward, thereby causing the limit rod 332 and the limit block 333 to open to both sides;

[0041] (2) When the upper surface limiting device 31 is about to touch the upper surface of the mushroom stick, the pressing plate 32 is released. At this time, the limiting vertical rod 332 and the limiting block 333 are retracted, clamping the two sides of the mushroom stick to play a limiting role; at this time, the entire machine continues to move downward until the upper surface limiting device 31 touches the upper surface of the mushroom stick;

[0042] (3) The three motors 411 are started simultaneously, driving the twelve blades 42 to rotate, completing the cutting of three holes on a mushroom stick, and then the waste membrane is manually removed.

[0043] Repeat this process to cut the next mushroom stick.

[0044] Thus, this embodiment can realize simultaneous cutting of three holes of a mushroom stick, and can ensure that the cutting depth and the incision formed by expanding the hole are regular in shape and stable in size. The whole is small and light, suitable for the working environment of Tremella fuciformis mushroom sticks, and convenient for operators.
