Description

Technical Field

[0001] This utility model relates to a fruit collection device for slopes, belonging to the field of fruit picking and collection technology. Background Technology

[0002] Camellia oleifera trees are not demanding in terms of terrain and can be planted in many locations. They can be planted not only in orchards with uneven terrain but also on slopes with a certain gradient. They are a widely planted economic forest fruit tree in the hilly and mountainous areas of southern China. After ripening, the fruit is usually collected by mechanically shaking it to the ground. To improve harvesting efficiency and reduce fruit damage, modern mechanized harvesting commonly uses vehicle-mounted camellia oleifera fruit harvesting equipment, such as the harvesting equipment disclosed in patent documents CN119234572A, CN117280942A, and CN114271100A. However, vehicle-mounted camellia oleifera fruit harvesting equipment is relatively large. In forested and mountainous areas with poor working conditions, harvesting machinery cannot enter or operate effectively due to issues of accessibility, maneuverability, safety, and damage to the terrain. Using separate vibratory harvesting equipment and fruit collection equipment can effectively reduce the size of the equipment and is more practical in the complex terrain conditions of the hilly areas of southern my country. The main type of fruit collection equipment is the inverted umbrella type. The inverted umbrella type refers to the umbrella cloth and ribs being unfolded and the two ends of the umbrella cloth being connected with zippers or Velcro to form an inverted umbrella shape. It is widely used, but when harvesting fruit on steep slopes (often exceeding 20° or even 30°), the fruit collection umbrella is set up at an angle and needs to be held manually to prevent it from sliding down the slope. In order to avoid manual handling, the fruit collection umbrella is also held tightly to the tree trunk to position it. However, the collection umbrella has poor stability during the fruit shaking process and is prone to shaking. In addition, because the collection umbrella is on the slope, there is a certain height difference between its front and rear ends. The shaking of the collection umbrella during the fruit collection process will cause fruit to be missed or run away, affecting the fruit collection rate and practicality. Utility Model Content

[0003] The fruit collection device for slopes provided by this utility model not only prevents the collection device from sliding down the slope, but also improves the stability of the collection umbrella on the slope, reduces the shaking of the collection umbrella when the fruit falls in, and reduces the height difference between the front and rear ends of the collection umbrella, thereby reducing the probability of fruit leakage and escape. It can be adapted to fruit collection on slopes with different gradients, improving the fruit collection rate and practicality.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A fruit collection device for slopes includes a ring frame, umbrella ribs hinged to the ring frame, and an umbrella cloth that is sequentially connected to the umbrella ribs and can be unfolded to form a collecting umbrella. The ring frame is characterized by comprising a U-shaped frame, two arc rods respectively hinged to the U-shaped frame, and a ground nail vertically fixed to the front end of the U-shaped frame. The two arc rods are symmetrically arranged on both sides of the U-shaped frame and can be detachably connected. The two arc rods and the U-shaped frame together form a ring that can be fitted around the outer circumference of the tree trunk. The umbrella ribs are hinged to the arc rods and the U-shaped frame.

[0005] Preferably, the U-shaped frame is composed of a semi-circular segment formed by a semi-circle and strip segments integrally formed at both ends of the semi-circular segment. Ground nails are fixed to the front end of the strip segments respectively. One end of the arc rod is hinged to the end of the semi-circular segment. The two arc rods are connected by a buckle and enclose the semi-circular segment to form a ring. Multiple umbrella ribs are hinged to the arc rod and the semi-circular segment respectively, forming a uniformly spaced distribution of umbrella ribs on the ring.

[0006] Preferably, the umbrella ribs are hinged to the arc rod and the semicircular segment respectively by bearing assemblies. The bearing assembly includes a fisheye bearing, a connecting rod threadedly connected to the fisheye bearing, an umbrella rib connector mounted on the fisheye bearing, and a limiting support fixed on the connecting rod. The lower end of the umbrella rib is coaxially fixed to the umbrella rib connector, the umbrella rib connector is supported on the limiting support, and the connecting rod is rotatably connected to the arc rod and the semicircular segment respectively.

[0007] Preferably, through holes corresponding to the connecting rod are opened on both the arc rod and the semicircular segment. The connecting rod passes through the through holes and is positioned by the positioning pin inserted at its bottom. The through hole at one end of the arc rod is aligned with the through hole at the end of the semicircular segment. The connecting rod passes through one end of the arc rod and the end of the semicircular segment to hinge one end of the arc rod to the end of the semicircular segment.

[0008] Preferably, the limiting support is L-shaped, with its lower end fixed to the connecting rod, and the umbrella rib connector supported on the upper end of the limiting support to tilt the umbrella rib.

[0009] Preferably, both the arc rod and the semicircular segment have upwardly inclined fixed edges fixed along their top edges, and leak-proof plates are attached to the fixed edges. The leak-proof plates on the arc rod and the semicircular segment together prevent the fruit from leaking into the ring.

[0010] Preferably, a collection opening is made on the canopy between adjacent ribs on the semicircular segment, and a fruit collection bag is connected to the collection opening.

[0011] The beneficial effects of this utility model are: This utility model discloses a fruit collection device for slopes. Two arc-shaped rods are hinged to a U-shaped frame. The two arc-shaped rods are detachably connected and, together with the U-shaped frame, form a ring that can be fitted around the tree trunk. A ground nail is fixed to the front end of the U-shaped frame. To install the collection device under the fruit tree, first align the U-shaped frame with the tree trunk and push it in so that the trunk enters the U-shaped frame. Then, connect the two arc-shaped rods to form a ring that fits onto the tree trunk. Next, insert the ground nail into the ground to fix the collection device to the ground. Finally, unfold the umbrella cloth and ribs to form a collection umbrella, thus completing the collection process. The installation involves using two curved rods and a U-shaped frame to enclose the collection device on the tree trunk. Ground nails are inserted into the ground to fix the collection device to the ground, preventing it from sliding down the slope and improving the stability of the collection umbrella on the slope. This reduces the shaking of the collection umbrella when fruits fall in. The tilt angle of the collection umbrella can be adjusted by changing the insertion depth of the ground nails to reduce the height difference between the front and back ends of the collection umbrella, thereby reducing the probability of fruit leakage and escape. This method can adapt to fruit collection on slopes with different gradients, improving the fruit collection rate and practicality. Attached Figure Description

[0017] The following is combined with Figures 1 to 5 The embodiments of this utility model will be described in detail below.

[0018] A fruit collection device for slopes includes a ring frame, umbrella ribs 1 hinged to the ring frame, and an umbrella cloth 2 that is sequentially connected to each umbrella rib 1 and can be unfolded to form a collection umbrella. The ring frame includes a U-shaped frame 3, two arc rods 4 respectively hinged to the U-shaped frame 3, and ground nails 5 vertically fixed to the front end of the U-shaped frame 3. The two arc rods 4 are symmetrically arranged on both sides of the U-shaped frame 3 and can be detachably connected. The two arc rods 4 and the U-shaped frame 3 together form a ring 6 that can be fitted around the outer circumference of the tree trunk. The umbrella ribs 1 are hinged to the arc rods 4 and the U-shaped frame 3.

[0019] The above-described fruit collection device for sloping land consists of an arc-shaped rod 4 hinged to a U-shaped frame 3. Two arc-shaped rods 4 are detachably connected and, together with the U-shaped frame 3, form a ring 6 that can be fitted around the tree trunk. Ground nails 5 are fixed to the front end of the U-shaped frame 3. To install the collection device under the fruit tree, first align the U-shaped frame 3 with the tree trunk and push it in so that the trunk enters the U-shaped frame 3. Then, connect the two arc-shaped rods 4 to form the ring 6, which is then fitted onto the tree trunk. Next, insert the ground nails 5 into the ground to fix the collection device to the ground. Finally, unfold the umbrella cloth 2 and umbrella ribs 1 to form a collection umbrella, thus completing the process. The collection device is installed by combining two arc rods 4 with a U-shaped frame 3 to fit the collection device onto the tree trunk. Ground nails 5 are inserted into the ground to fix the collection device to the ground, which not only prevents the collection device from sliding down the slope, but also improves the stability of the collection umbrella on the slope and reduces the shaking of the collection umbrella when the fruit falls. The tilt angle of the collection umbrella can be adjusted by adjusting the insertion depth of the ground nails 5 to reduce the height difference between the front and rear ends of the collection umbrella, thereby reducing the probability of fruit leakage and escape. It can adapt to fruit collection on slopes with different gradients, improving the fruit collection rate and practicality.

[0020] The U-shaped frame 3 is composed of a semi-circular segment 31 formed by a semicircle and strip segments 32 integrally formed at both ends of the semi-circular segment 31. Ground nails 5 are fixed to the front end of the strip segments 32 respectively. One end of the arc rod 4 is hinged to the end of the semi-circular segment 31. The two arc rods 4 are connected by buckles 8 and surround the semi-circular segment 31 to form a ring 6. Multiple umbrella ribs 1 are hinged to the arc rod 4 and the semi-circular segment 31 respectively, forming a uniformly spaced distribution of umbrella ribs 1 on the ring 6. When the two arc rods 4 are separated, the arc rods 4 are rotated outward on the U-shaped frame 3, so that the opening of the U-shaped frame 3 is open. The tree trunk can enter the U-shaped frame 3 as it is pushed in. The two arc rods 4 are connected together by the buckle 8. The semicircular segment 31 and the two arc rods 4 enclose each other to form a ring 6. The collecting device is put on the tree trunk. The ground nail 5 at the front end of the strip segment 32 is inserted into the ground to fix the collecting device to the ground, ensuring that the entire collecting device will not slide down the slope or shake, thereby reducing the shaking of the collecting umbrella and improving the stability of the collecting device. The insertion depth of the ground nail 5 can be adjusted according to the slope of the ground, thereby adjusting the tilt angle of the collecting umbrella and reducing the height difference between the front and rear ends of the collecting umbrella, so as to reduce the probability of fruit leakage and escape from the collecting umbrella during collection and improve the collection rate.

[0021] The umbrella rib 1 is hinged to the arc rod 4 and the semicircular segment 31 respectively via a bearing assembly 7. The bearing assembly 7 includes a fisheye bearing 71, a connecting rod 72 threadedly connected to the fisheye bearing 71, an umbrella rib connector 73 mounted on the fisheye bearing 71, and a limiting support 74 fixed to the connecting rod 72. The lower end of the umbrella rib 1 is coaxially fixed to the umbrella rib connector 73, and the umbrella rib connector 73 is supported on the limiting support 74. The connecting rod 72 is rotatably connected to the arc rod 4 and the semicircular segment 31 respectively. Figure 3As shown, the lower end of the fisheye bearing 71 is threadedly connected to the connecting rod 72, the limiting support 74 is installed on the upper end of the connecting rod 72, and the umbrella rib connector 73 is assembled in the inner hole of the fisheye bearing 71 and coaxially fixed to the lower end of the umbrella rib 1, so that the umbrella rib 1 can rotate relative to the fisheye bearing 71, satisfying the rotation requirements of the umbrella rib 1 when the umbrella fabric is unfolded or closed. The umbrella rib connector 73 is supported on the limiting support 74, which limits the tilt angle of the umbrella rib 1 when the umbrella fabric 2 is fully unfolded. The connecting rod 72 is rotatably mounted on the arc rod 4 and the semi-circular section 31. When the umbrella fabric 2 is unfolded, the umbrella fabric 2 pulls the umbrella rib 1 to rotate, and the connecting rod 72 rotates with the rotation of the umbrella rib 1.

[0022] Both the arc rod 4 and the semicircular segment 31 have through holes corresponding to the connecting rod. The connecting rod 72 passes through the through holes and is positioned by the positioning pin 75 inserted at its bottom. The through hole at one end of the arc rod 4 is aligned with the through hole at the end of the semicircular segment 31. The connecting rod 72 passes through one end of the arc rod 4 and the end of the semicircular segment 31, and hinges one end of the arc rod 4 to the end of the semicircular segment 31. The connecting rod 72 passes through the through hole and is inserted into the arc rod 4 and the semicircular segment 31. The positioning pin 75 prevents the connecting rod 72 from detaching from the arc rod and the semicircular segment 31. The through holes at one end of the arc rod 4 and the end of the semicircular segment 31 are aligned. The insertion of the connecting rod 72 and the positioning pin 75 limit the connection of the connecting rod 72 to form a hinge between the arc rod 4 and the semicircular segment 31. The simple structure allows the arc rod 4 to rotate freely on the semicircular segment 31. When the two arc rods 4 rotate to contact each other, the buckle 8 is fastened, so that the two arc rods 4 are connected and can no longer rotate. The two arc rods 4 and the semicircular segment 31 enclose to form a ring 6. When the buckle 8 is released, the arc rod 4 can be rotated outward, so that the opening of the U-shaped frame 3 is in an open state.

[0023] The limiting support member 74 is L-shaped, with its lower end fixed to the connecting rod 72. The umbrella rib connector 73 is supported on the upper end of the limiting support member 74, causing the umbrella rib 1 to be tilted. When the umbrella fabric 2 is fully unfolded to form a collecting umbrella, the limiting support member 74 supports the umbrella rib 1 at a certain tilt angle.

[0024] The arc rod 4 and the semicircular segment 31 are both fixed with upwardly inclined fixing edges 9 along their top edges. Leak-proof plates 10 are attached to the fixing edges 9. The leak-proof plates 10 on the arc rod 4 and the semicircular segment 31 together prevent the fruit from leaking into the ring 6. Figure 1 As shown, the anti-leakage plate 10 forms an upward-convex cone shape, which can prevent the fruit from falling into the ring 6 and reduce the fruit leakage rate.

[0025] A collection opening 21 is provided on the umbrella fabric 2 between adjacent umbrella ribs 1 on the semicircular segment 31, and a fruit collection bag 22 is connected to the collection opening 21. After the fruit falls into the collection umbrella, the fruit can be pushed into the fruit collection bag 22. After the fruit collection bag 22 is full, the fruit collection bag 22 is removed and the fruit is poured into the centralized collection point. Then the fruit collection bag is reconnected to the collection opening 21 to form a rapid centralized collection of fruit and improve collection efficiency.
