Description

Technical Field

[0001] This utility model belongs to the field of shiitake mushroom cultivation technology, specifically relating to a shiitake mushroom picking cart for contestants. Background Technology

[0002] After the shiitake mushrooms mature, they need to be harvested. During harvesting, operators remove the mushrooms from the growing racks and place them into harvesting baskets. To facilitate the movement of the baskets, operators usually place them on a handcart and push the handcart between the growing racks to harvest the mushrooms. During harvesting, the harvested mushrooms need to be sorted according to size and quality, with different sizes and qualities placed in different harvesting baskets. However, the limited space on the handcart limits the number of baskets that can be placed, making it impossible to harvest multiple sizes of mushrooms simultaneously. This necessitates harvesting in batches, impacting harvesting efficiency. Utility Model Content

[0003] This utility model provides a handcart for picking shiitake mushrooms, which aims to solve the problem that the handcarts used in the existing technology cannot meet the needs of picking shiitake mushrooms of various sizes at the same time, thus affecting the picking efficiency.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a shiitake mushroom picking contestant cart, comprising:

[0025] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] Please refer to the following: Figures 1 to 3The present invention provides a description of the mushroom picking competition cart. The mushroom picking competition cart includes a cart body 1, a rotating frame 2, and a placement frame 3. The rotating frame 2 is rotatably mounted on the cart body 1; multiple placement frames 3 are freely hinged to the rotating frame 2. The rotating frame 2 is provided with multiple outwardly extending support arms 21, and the placement frames 3 are provided with upwardly extending connecting arms 31 for hinged connection to the ends of the support arms 21. The placement frames 3 are used to place picking baskets.

[0027] The mushroom picking cart provided in this embodiment, compared with the prior art, features a cart body 1 with uprights fixedly installed on both sides, the length of which is vertical. A central shaft is fixedly installed between the two uprights, and two rotating sleeves are fixedly installed on a rotating frame 2, rotatably mounted on the central shaft. Multiple support arms 21 extend outward from the rotating frame 2, and placement racks 3 are freely hinged at the ends of the support arms 21 away from the central shaft. A connecting arm 31 is fixedly installed on the top of the placement rack 3, and the top of the connecting arm 31 is hinged to the support arm 21, ensuring that the placement rack 3 remains below the support arm 21 in a free state. In use, multiple picking baskets can be placed on the placement rack 3. When switching picking baskets, the rotating frame 2 can be rotated to switch the corresponding basket. By pushing the cart body 1 to the planting rack, operators can classify the picked mushrooms and place them into multiple picking baskets. During a single harvesting trip, multiple sizes of shiitake mushrooms can be harvested simultaneously, improving harvesting efficiency.

[0028] In some embodiments, the aforementioned placement rack 3 may be adopted as follows: Figure 2 The structure shown. See also Figure 2 There are two connecting arms 31, located at opposite ends of the placement frame 3. Each connecting arm 31 consists of two intersecting diagonal rods, with the intersection of the two rods hinged to the support arm 21. Connecting arms 31 are also provided on one side of the placement frame 3. Each connecting arm 31 is composed of two intersecting diagonal rods arranged at an angle, with the intersection of the two rods located directly above the center of the placement frame 3. The intersection of the two diagonal rods is freely hinged to the support arm 21. By using two connecting arms 31, in the free state, the placement frame 3 is always positioned below the support arm 21, and the opening of the harvesting basket on the placement frame 3 always faces upwards. This prevents the harvesting basket from tilting and causing the mushrooms to fall out when the rotating frame 2 is rotated, thus improving stability during use.

[0029] In some embodiments, the aforementioned placement rack 3 may be adopted as follows: Figure 2 The structure shown. See also Figure 2The placement rack 3 has an opening on one side for easy access to the picking baskets. A detachable stop bar 4 is installed at the opening to prevent the picking baskets from sliding out. An opening is also provided on the side of the placement rack 3 away from the central axis of the vehicle body 1, allowing operators to place or remove the picking baskets through this opening. This improves ease of use.

[0030] Specifically, in this embodiment, the placement rack 3 can be made of welded steel pipes, which can reduce the weight of the overall welded rack. According to the size of the picking basket, a placement groove that matches the outer size of the picking basket is formed by steel pipes. The opening is located on one side of the placement groove, and the picking basket can slide out from the side of the opening, making it convenient to retrieve the picking basket later.

[0031] Specifically, in this embodiment, a stop bar 4 can be detachably installed on the placement rack 3. The stop bar 4 is located at the opening, which can limit the picking basket from sliding out of the opening. When the placement rack 3 is slightly tilted, it can prevent the picking basket from sliding out of the opening and improve the stability during use.

[0032] In some embodiments, the aforementioned stop 4 may be adopted as follows: Figure 2 The structure shown. See also Figure 2 Both ends of the stop bar 4 are connected to elastic elements 5. The other end of the elastic element 5 is installed on the placement frame 3. The elastic element 5 is used to pull the stop bar 4 against the side of the placement frame 3 with an opening. The elastic element 5 is a tension spring, with one end installed on the pull rod and the other end installed in the middle of both ends of the placement frame 3. In use, after the picking basket is installed on the placement frame 3, one side of the picking basket is located at the opening. This allows the pull rod to abut against the side wall of the picking basket. On the one hand, it can limit the picking basket inside the placement frame 3. At the same time, the force of the elastic element 5 can make the opposite side wall of the picking basket abut against the placement frame 3, ensuring the stability of the picking basket's installation position.

[0033] In some embodiments, the aforementioned placement rack 3 may be adopted as follows: Figure 1 , Figure 2 The structure shown. See also... Figure 1 , Figure 2 The placement rack 3 has an opening on one side that is angled inwards from bottom to top. When the picking basket is installed inside the placement rack 3, the side of the picking basket protrudes beyond the angled side of the placement rack 3. When the stop bar 4 is pulled by the elastic element 5, it moves upwards and inwards along the angled side until it abuts against the side wall of the picking basket. Therefore, even when the picking baskets are of different sizes, the stop bar 4 can abut against the inner wall of the placement rack 3, located at the intersection of the side of the opening of the placement rack 3 and the picking basket, ensuring the stability of the picking basket installed inside the placement rack 3.

[0034] In some embodiments, the rotating frame 2 may be adopted as follows: Figure 1 , Figure 3 The structure shown. See also... Figure 1 , Figure 3 A damping mechanism 6 is provided between the rotating frame 2 and the vehicle body 1 to increase the friction between them. A central shaft is fixedly mounted on the vehicle body 1, and a rotating sleeve rotatably mounted on the central shaft is fixedly mounted on the rotating frame 2. The damping mechanism 6 is provided between the rotating sleeve and the central shaft. The damping mechanism 6 increases the friction between the central shaft and the rotating sleeve. This ensures the stability of the rotating frame 2's position on the vehicle body 1 in the absence of external force. It prevents the rotating frame 2 from rotating arbitrarily relative to the vehicle body 1 during harvesting, thus avoiding instability in the harvesting basket's position and affecting the operator's work.

[0035] In some embodiments, the damping mechanism 6 described above may employ, for example... Figure 3 The structure shown. See also Figure 3 The damping mechanism 6 includes a damping ring 61, a limiting rod 62, and an elastic pull member 63. The damping ring 61 is fixedly mounted on the rotating frame 2, and its outer side is recessed with multiple arc-shaped grooves. The limiting rod 62 is slidably mounted on the vehicle body 1, and can slide into the arc-shaped grooves to limit the rotation of the damping ring 61. The elastic pull member 63 is installed between the vehicle body 1 and the limiting rod 62, and is used to pull the limiting rod 62 into the arc-shaped grooves. Multiple arc-shaped grooves are recessed on the outer ring of the damping ring 61, and these grooves are evenly spaced along the circumference of the damping ring 61. The limiting rod 62 is also slidably mounted on the vehicle body 1, with its length direction along the axial direction of the damping ring 61, and it always fits against the outer wall of the damping ring 61.

[0036] Specifically, in this embodiment, during use, the limiting rod 62 abuts against the outer wall of the damping ring 61 under the action of the elastic pull member 63. When the limiting rod 62 moves into the arc-shaped groove, the damping ring 61 experiences a certain resistance during rotation under the action of the elastic pull member 63. Only under the action of a certain external force can the limiting rod 62 slide out from the arc-shaped groove, thereby achieving a certain damping effect. This means that during the rotation of the rotating frame 2, the operator needs to apply a certain external force to drive the rotating frame 2 to rotate, while in the free state, the rotating frame 2 maintains a relatively stable state, making it convenient for the operator to place the mushrooms into the picking basket.

[0037] Specifically, in this embodiment, a slider is slidably arranged on the vehicle body 1 in the vertical direction, a limiting rod 62 is fixedly installed on the slider, and an elastic tension member 63 is a tension spring. The two ends of the elastic tension member 63 are respectively connected to the vehicle body 1 and the slider, and are used to pull the slider to move towards the axis direction close to the damping ring 61.

[0038] In some embodiments, the damping ring 61 may be adopted as follows: Figure 3 The structure shown. See also Figure 3 The damping ring 61 and the rotating frame 2 are coaxially arranged on the axis of the vehicle body 1, and the limiting rod 62 is slidably arranged on the vehicle body 1 along the radial direction of the damping ring 61. The damping ring 61 is fixedly installed on the rotating frame 2. When the damping ring 61 rotates, it will rotate together with the rotating frame 2, and the damping ring 61 is coaxially arranged with the central axis on the vehicle body 1. The number of arc-shaped grooves on the damping ring 61 corresponds one-to-one with the number of placement racks 3 on the rotating frame 2. The multiple damping rings 61 and multiple placement racks 3 are evenly spaced along the circumference of the rotating frame 2. When the limiting rod 62 slides into the root of the arc-shaped groove on the damping ring 61, the support arm 21 corresponding to one of the placement racks 3 is in a horizontal state. This makes it easier for operators to put the mushrooms into the picking basket.

[0039] In some embodiments, the aforementioned stop 4 may be adopted as follows: Figure 1 , Figure 2 The structure shown. See also... Figure 1 , Figure 2 The stop bar 4 can be attached to the bottom of the placement rack 3, and the elastic element 5 is used to pull the stop bar 4 against the bottom of the placement rack 3. When it is necessary to place the picking basket on the placement rack 3, the stop bar 4 can be pulled down and moved to the bottom of the placement rack 3, thereby preventing the stop bar 4 from covering the placement or removal of the picking basket. When the picking basket is placed on the placement rack 3, the stop bar 4 can be moved so that the stop bar 4 is attached to the intersection between the picking basket and the side of the placement rack 3.

[0040] Specifically, in this embodiment, the elastic element 5 is a tension spring, and one end of the elastic element 5 is a hook. A positioning rod for hanging the hook is fixedly installed on the outer wall of the placement frame 3. This facilitates the adjustment of the position of the stop bar 4 on the placement frame 3. The structure is simple and makes it easier to pick up and put down the picking basket.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
